Made a lot of effort for the location of wireless device, the most attractive is Federal Communications Committee (FCC) rule of supporting to be used to strengthen 911 (E911) Phase.(911 (E911) of wireless enhancing rule is through providing additional information to manage to improve the efficient and the reliability of wireless 911 services for 911 yardmans when the wireless 911 call.E911 program that this is wireless is divided into two parts, Phase I and Phase.After effective request of local public safety answering point (PSAP), Phase I needs carrier wave to report wireless 911 caller's telephone number and the aerial position that receives conversation.Phase in most of the cases needs wireless carrier to go to provide accurate more positional information in 50 to 300 meters.The popularization of E911 need the exploitation of new technology and to renewal of local 911 PSAP or the like).In the E911 Phase, the trust of FCC has comprised the desired position degree of accuracy based on circular error probability.Need web-based system (at the wireless location system of gathering radio signal on the network receiver) to satisfy in 100 meters 67% caller and 95% caller's degree of accuracy in 300 meters.Need be based on the system of hand-held set (at the wireless location system of gathering radio signal on the movement station) to satisfy in 50 meters 67% caller and 95% caller's degree of accuracy in 100 meters.Wireless carrier is allowed to be adjusted at the setting accuracy on the service area, therefore, can not guarantee the degree of accuracy of any given position estimation.

Though some reason; Such as; Degree of accuracy and output (number of the successful location of each calling) are limited FCC; Being used for the single LBS service of E911, is not extra service quality (QoS) parameter, such as reaction time (location and delivering position are estimated to the time of request or selected application program).The FCC relevant with the degree of accuracy of the particular example that is used for cellular call is set at emergency (911 centers or PSAP).The degree of accuracy criteria limit of the strictness of state-of-the-art and FCC is used for applying widely the choice of technology of location technology.The based on network option that is used for the E911 Phase comprises the up-link arrival time poor (U-TDOA), arrives at angle (AoA) and TDOA/AoA mixing.The non-based on network location option that is used for the E911 Phase comprises the use with the Navistar GPS of augmenting from land side data in server (GPS), and it comprises synchronization timing, orbital data (astronomical ephemeris) and obtains data (code phase and Doppler's distance).

Except the FCC E911 that is used for wireless voice communication adapts to positioning system, other use arrival time (TOA), arrival time poor (TDOA), arrive at angle (AoA), arrive at power (POA), the wireless location system that arrives at difference power can be used for manifesting and satisfies the specific position based on positioning service (LBS) demand.

In following detailed description part, we provide the relevant location technology that can combine to adopt with the present invention and the more background information of wireless communication system.In the remainder of background information part, we provide relevant wireless location system more background information.

At United States Patent(USP) No. 5; 327; 144; On July 5th, 1994, in " Cellular Telephone Location System (cell phone positioning system) " the early stage work relevant with wireless location system has been described, this patent discloses the system that a kind of mistiming (TDOA) technology of using arrival is used for locating cellular telephone.At United States Patent(USP) No. 5; 608; On March 4th, 410,1997, " System for Locating a Source of Bursty Transmissions (being used for locating the system in the source of burst transfer) " disclose ' 144 patents in the further improvement of disclosed system.These two patents all transfer assignee TruePosition of the present invention company.TruePosition continues the significant improvement of exploitation to original inventive concept.

In the past few years; Cellular industry has improved the number of the air interface protocol that can be used by wireless telephone; Improve the number of wireless or the frequency band that mobile phone can be worked; Refer to or relate to the number of mobile phone term with expansion, to comprise " PCS ", " wireless " or the like.The air interface protocol that uses in the wireless industry now comprises AMPS, N-AMPS, TDMA, CDMA, GSM, TACS, ESMR, GPRS, EDGE, UMTS WCDMA or the like.

Wireless communication industry has been admitted the value and the importance of wireless location system.In June, 1996, this Federal Communications Committee's promulgation is used for wireless communication industry to dispose the requirement of the positioning system that supplies the wireless 911 caller's use in location.The distribution of these systems is disposed because dwindle the use of emergency response resource, so can dwindle emergency response time, the life-span of saving and save huge cost widely.In addition, observe and research is reached a conclusion, various wireless applications will have very big commercial value in the future such as the charging of position sensing, queuing management or the like.

As mention that wireless communication industry in the U.S. and in the world, is used many air interface protocols in the different frequency band ranges.Usually, air interface and frequency band range do not influence the efficient of wireless location system on the wireless telephone of location.

All air interface protocols use the channel of two classifications, and wherein channel is defined in of a plurality of transmission paths in the single link between the several points in the wireless network.Channel can be through frequency, through bandwidth, through synchronous time slot, limit through coding, offset keying, modulation scheme or the combination in any through these parameters.Be called the information that control or first classification of access channel are used to carry relevant wireless telephone or transmitter, be used for starting or end call, perhaps be used to transmit pulse data.For example, the Short Message Service of some type transmits data on control channel.Different air interface uses different terms to remove the description control channel, and still, the function of control channel is similar in each air interface.Be called as the typically transport voice or the data communication on the interface aloft of channel of second classification of voice or Traffic Channel.In case used control channel to set up calling, Traffic Channel begins to be used.Voice and user data channel typically use special-purpose resource, that is, this channel can only be used by single mobile device, and control channel uses resources shared, that is, this channel can be by a plurality of user captures.Voice-grade channel does not deliver the identifying information of relevant wireless telephone or transmitter usually when transmission.Though for some application site on voice-grade channel possibly be best, to use for some wireless location, this difference can make the use of control channel more worthwhile more economically than the use of voice-grade channel.

Following paragraph is discussed some difference of interface protocol aspect aloft:

AMPS, this is the original aerial interface protocol that is used for cellular communication in the U.S., and in TIA/EIA standard I S 553A, describes.The independent dedicated channel of AMPS system assignment supplies control channel (RCC) to use; It is according to frequency and definitions of bandwidth; And be used for transmitting from BTS to the reverse voice channel of mobile phone A (RVC); Be used for from the mobile phone to BTS, transmitting, can take any channel, this channel is not distributed to control channel.

N-AMPS, this air interface is the expansion of AMPS air interface protocol, and in EIA/TIA standard I S-88, defines.It uses substantially and the identical control channel that in AMPS, uses, but is to use the different voice-grade channel with different bandwidth and modulation scheme.

TDMA also is called D-AMPS, and the characteristics of this interface that in EIA/TIA standard I S-136, defines are that frequency of utilization separates with the time.Digital control channel (DCCH) is transmitted with pulse in distributed time slot, and this time slot possibly appear in the frequency band Anywhere.Digital service channel (DTC) possibly take the frequency assignation identical with the DCCH channel, but in given frequency assignation, does not take identical time slot allocation.In cellular band, be held independent as long as be used for the frequency assignation of each agreement, carrier wave can use AMPS and TDMA agreement.

CDMA is that by the characteristics of this air interface of EIA/TIA standard I S-95A definition frequency of utilization separates with code.Because adjacent cells can use identical frequency sets, CDMA must operate under the power control of extreme care, is produced as the situation of the far-near problem that those skilled in the art know; Make the method for most of wireless location be difficult to obtain accurate position (still, referring to the United States Patent(USP) No. that is used to address this problem 6,047; On April 4th, 192,2000, Robust; Efficient, Localization System).Control channel (in CDMA, being known as access channel) can be shared identical frequency band with Traffic Channel, but is separated by coding.

GSM is that by the characteristics of this air interface of the international standard global system definition that is used for mobile communication frequency of utilization separates with the time.GSM distinguishes between physical channel (time slot) and logic channel (information that is transmitted by physical channel).Some reproduction time slots on carrier wave constitute physical channel, and it is to be used to transmit the information of user data and signaling by the different logical channel.

Control channel (CCH) comprises BCCH (BCCH), CCCH (CCCH) and DCCH (DCCH), and it is transmitted with pulse in the time slot of distribution that supplies CCH to use.CCH can being assigned with at frequency band Anywhere.Traffic Channel (TCH) can take identical frequency assignation with CCH, but in given frequency assignation, does not take identical time slot allocation.CCH uses the identical modulation scheme that is called as GMSK with TCH.The packet radio service (GPRS) that GSM is general and be used for the data rate that GSM develops the enhancing of (EDGE) system and reuse the GSM channel architecture still, can use a plurality of modulation schemes and data compression so that higher data throughput to be provided.GSM, GPRS and EDGE radio protocol range the classification that is called GERAN or GSM edge radio access network.

UMTS is called UTRAN (UMTS terrestrial radio electricity access network) strictly speaking, is by the air interface as the succession's of GERAN agreement international standard third generation partner program definition.UMTS also is called as WCDMA (perhaps W-CDMA) sometimes, and it represents WCDMA.WCDMA is direct expansion technique, and this refers to it will expand its transmission on wide 5MHz carrier wave.

WCDMA FDD (FDD) UMTS air interface (U-interface) is separated physical channel through frequency and code.WCDMA TDD (time division duplex) UMTS air interface is separated physical channel through utilizing frequency, time and code.All distortion of this UMTS radio interface comprise the logic channel that is mapped as transmission channel, and it is mapped as W-CDMA FDD or TDD physical channel once more.Because adjacent cell site can use identical frequency sets, WCDMA also uses the power control of extreme care to be directed against the common near-far problem of all cdma systems.Control channel is considered to access channel in UMTS, and data or voice-grade channel are considered to Traffic Channel.Insert and to share identical frequency band and modulation scheme, but separate by code with Traffic Channel.In this instructions, control and the access channel introduced usually, perhaps the voice-and-data channel refers to all types of controls or voice-and-data channel, and what the preferred term that no matter is used for specific air interface is.In addition, be given in the air interface (for example, IS-95CDMA, CDMA 2000, UMTS and W-CDMA) of many types of using in the whole world, this instructions is not got rid of any air interface from the inventive concept of describing herein.Those skilled in the art will recognize that the interface of other that uses in other place is derivant or analog in aforesaid those classification.

The GSM network provides many potential problems for existing wireless location system.At first, when Traffic Channel in use the time, the wireless device that is connected to the GSM/GPRS/UMTS network seldom transmits.The use of using and be used for safe interim nickname (interim moving station mark symbol (TMSI)) of on Traffic Channel, encrypting provides to be used to trigger the limited serviceability that wireless location system is perhaps kept watch on for the radio net of wireless location system assigned tasks.The wireless device that is connected to such GSM/GPRS/UMTS radio net only periodically " is listened to " transmission that is used for wireless device; And except during the call setup, voice/data computing and the conversation fault, do not transmit signal and give zonal receiver.This has reduced the probability that detects the wireless device that is connected to the GSM network.Through " bang (pinging) " all wireless devices in a zone on one's own initiative, it is possible for overcoming that this limits.But this method is placed on big emphasis on the performance of wireless network.In addition, the activity of wireless device bang can warn mobile device user to use this positioning system to lower efficiency, perhaps increase worry based on the application of poll location.

The application No.11/198 that more than quotes; 996; " Geo-Fencing in a Wireless Location System " described by wireless location system and adopted, the method and system that the wireless device that is moved in the geographic area limiting of wireless communication system services is positioned.In such system, can delimit geographic restrictions zone (geo-fenced area), then, can keep watch on one group of predetermined signal link of this wireless communication system.This supervision also can comprise any one that detects mobile device and carried out following behavior with respect to the geographic restrictions zone: (1) gets into the geographic restrictions zone; (2) withdraw from geographic restrictions zone and (3) entering within the scope of the predetermined degree of approach of approaching geographical restricted area.In addition, this method can also comprise at least one the detection of having carried out these behaviors in response to this mobile device, triggers the positioning function of the pinpoint accuracy in the geographic position that is used for confirming this mobile device.The application has described the notion that is used to use the geographic restrictions zone; With based on geographic position of calculating and the lane place of presetting delimited by local, regional or national legal jurisdiction, allow, allow selectively, limit, refuse or postpone some function or service method and system.But the present invention is in no way limited to be employed in the above application No.11/198 that quotes, the system of describing in 996 around earth technology.

It is the radar detector as being used for the networking of vehicle that a demonstration of the distortion of this LDP client device 110 is used, perhaps as the WiFi hotspot locator.Under two kinds of situation, this LDP server 220 is used to record to send to the network information and the position of the application that can locate the outside.

The use of the accurate timing that is used for dispatching communication is derived in the outside

Battery life possibly be at least some key in application that can be used in the location specialized equipment of providing for oneself.In addition, can predict with in the specialized equipment of location, periodically charging or replace the relevant effort of battery is the important cost reason.Equipment is considered to have three state: activation, idle, sleep.

Activate=with network service

Idle=as to be among the state that can get into state of activation

Sleep=low power state

Power consumption in state of activation is by numeral and the driving of the efficient of RF electronic equipment.It is ripe that these technology all are considered to, and its power consumption is considered to optimized.This power consumption in sleep pattern is to be driven by the amount that circuit during sleep state activates.Less circuit means power consumption still less.A kind of method with minimize power consumption is with minimizing in idle condition consumed time amount.During idle condition, this equipment must periodically be listened to networking command (paging), and if receive, get into state of activation.In standard movement station (MS), the paging command that when can occur being used for any particular mobile station through restriction minimizes the time quantum that expends in idle condition.

The absolute external time reference of this aspect utilization of the present invention (GPS, A-GPS, the information of perhaps on cellular network, broadcasting) is accurately to calibrate the inherent time reference of location private client equipment.The internal temperature sensor device will allow this equipment to remove the benchmark of temperature compensation its oneself.GPS or A-GPS receiver can be parts that is used for confirming based on the position of the LDP client device 110 of the position estimation of equipment engine.

Suppose that this location specialized equipment has the precise time benchmark, this network can go on precise time, to get into idle pattern by controlling equipment, thereby maximization expends the time quantum under minimum power rating.This method also will be minimized in the sleep pattern the unsuccessful trial with devices communicating, thereby will be minimized in the load on this communication network.

Speed, time, highly, regional service

This LDP client device functionality can be incorporated in other the electronic equipment.Likewise; Not only be based on the position in the service area; And based on being used for various electronic equipments; Such as time, speed or the height of cell phone, PDA, radar detector or other interactive system, LDP (by means of the database of service parameter that supplies to use and rule can with the location aware devices of external server wireless communication) can be used for permitting, restriction or denial of service.Time comprises the time and a period of time on daytime, and therefore, the duration of service can be limited.

Moving closer to of intelligence

This LDP client device 110 can with the pairing of another LDP client, with provide intelligence near service, should permit here, restriction or denial of service can be based on the right degrees of closeness of LDP.For example, in theft-prevention applications, LDP client device 110 can be integrated in the vehicle, and other LDP can be integrated in auto radio, navigational system or the like simultaneously.Right through in LDP server 220, the LDP groups of clients being registered as, and the trigger condition of confirming based on the position of activating or removing is set, generate a burglary-resisting system.Under the situation of unwarranted deletion, this LDP client device 110 in the equipment of removing can denial of service or permission service when the position of the stolen equipment that has merged the LDP client is provided.

F. location technology: based on network, based on equipment with hybrid

Each is wireless (radio), and positioning system comprises transmitter and receiver.This transmitter generates echo signal [s (t)], and it is by receiver collection and measurement.The measurement of echo signal can occur on wireless device or the network workstation.This transmitter or receiver can move in signal measurement interim.If the motion of any one (perhaps two) can accurately be limited (priori), the both can move.

Based on network location technology

When this measurement occurred on the network (the one or more receivers that distribute on the geography or the group of transceiver), this positioning system was considered to based on network.Based on network wireless location system can use TOA, TDOA, AOA, POA and PDOA to measure, usually be included in final position calculation in two or more independently measure and mix.The receiver of this networking or XCVR are known with different titles, comprise base station (honeycomb), access point (wireless local accesses network), reader (RFID), main frame (bluetooth) or sensor (UWB).

In web-based system, because this measured signal rises on this mobile device, web-based system receives and arrival time of measuring-signal, arrive at angle or signal intensity.The source of the site error in based on network positioning system comprises: network workstation topological structure, signal path loss, multiple signals, common channel signal disturb and the region profile.

The network workstation topological structure that has the website that is in line (along road) or have a website of neighbor site seldom is inappropriate for based on network location technology.

The signal path loss can or use higher emissive power to compensate through the long sampling period.Owing to allow lower emissive power, some radio environments (wide zone, multiple access insert spread spectrum system, such as IS-95 CDMA and 3GPP UMTS) have sense of hearing performance issue.

Because intensive urban environment especially is a problem, also will influence the output of setting accuracy and web-based system by the caused multiple signals of constructive and destructive interference of signal path reflection, diffraction.Can be used for a plurality of, the receiving antenna that separates of signals collecting and the back acquisition process of a plurality of reception signals compensates multichannel through utilization, before position calculation, from the signal of gathering, to remove time and frequency error.

Can pass through the distinctive characteristic of surveillance equipment (for example: color code), perhaps filter through digital common mode and the signal of gathering between correlativity be minimized in the common channel signal that multiple access inserts in the radio environment and disturb to remove the spur signal composition.

Based on network TOA

Based on network arrival time, system relied on from echo signal this device broadcasts and that received by this network workstation.The distortion of based on network TOA comprises following these of concluding.

Single workstation TOA

Can be between XCVR, sending, estimated distance two-way time of the polling signal that between XCVR, returns is then measured.In fact, this range observation is based on the TOA of this return signal.Range estimation combined with the known position of network node provides position estimation and error estimation.Single workstation TOA is useful in commingled system, and extra positional information in this commingled system is available such as arriving at angle or arriving at power.

In the CGI+TA localization method that an example of the commercial application of single workstation TOA technology is described in for the ETSI technical standard of GSM:03.71 and in positioning service (LCS); Functional description; Find among the level 2_23.171 by third generation partnership project (3GPP).

Synchronizing network TOA

Based on network TOA uses the absolute time that radio broadcasting is arrived on a plurality of receiver websites in the location in synchronizing network.Because signal is advanced with known speed, this distance can be calculated according to the arrival time on receiver.It is two points that the arrival time data of on two receivers, gathering will make the position constriction, and need go to resolve this accurate position from the TOA data of receiver.This network base station be important synchronously.The inaccurate position estimation error that directly is converted at the timing synchronization aspects.Other fixed error source that can measure is included in antenna and the reaction time of cable on the network receiver.

When (atomic) clock of superelevation degree of accuracy or GPS type radio time reference were realized property born and portability, the embodiment in the future that synchronizing network TOA is possible was the transmitter and receiver that is used to lock onto common time standard.When both have common timing when transmitter and receiver, can directly calculate the leap time, and confirm distance according to the leap time and the light velocity.

Asynchronous network TOA

Based on network TOA uses the relative time that radio broadcasting is arrived on based on network receiver in the location in asynchronous network.This Technology Need is known in distance between the website of single receiver and any difference in single receiver timing.This signal arrival time thereby can only stay the leap time between equipment and each receiver by standardization on the receiver website.Because radio signal is advanced with known speed, this distance can be calculated by the arrival time that on receiver, derive, standardized.The arrival time data of from three of more receiver, gathering will be used to resolve this accurate position.

Based on network TDOA

In arrival time of (up-link) Network Based difference wireless location system, with high degree of accuracy receive at a plurality of networks/transmitting-receiving station on to the echo signal of being sent gather, processing and mark timestamp.Thus, accurately know the position and the distance between several stations of each network workstation.This network receiving station timestamp otherwise need with highly firm clock high level of synchronization, or need know poor in the timing between receiving station.

Can represent from the mistiming of having measured between the signal of any a pair of receiving station collection by the hyperbolic curve of position.It is the somewhere on this hyperbolic curve that the position of this receiver can be confirmed as, and the mistiming between the received signal is constant here.Confirm the position between the receiving station is hyp at each through iteration, and calculate the point of crossing between hyperbolic curve, can confirm position estimation.

Based on network AoA

This AOA method is used a plurality of antennas or many antennas on the website of two or more receivers, to confirm the position of transmitter through the incident angle of the radio signal confirming on each receiver website, to confirm to arrive at.The initial description of position is provided in the cellular environment out of doors; Referring to United States Patent(USP) No. 4; 728; 959, " direction finding location (Direction Finding Localization) ", this AoA technology can also be used in the indoor environment of using ultrabroad band (UWB) or WiFi (IEEE 802.11) radiotelegraphy.

Based on network POA

Arriving at power is the approximate measure that between single network node and wireless device, uses.If this system is made up of the transceiver with forward direction available between equipment and network node and reverse radio channel, can order this wireless device to use certain power to be used for transmission, in addition, the power of this equipment transmitter should be known (priori).Because the power of radio signal is along with distance (from radiowave because the decay of air and the combined influence of free space loss, plane earth attenuation and diffraction loss) reduces, the estimation of this distance can be confirmed from receiving signal.With the simplest word, when the distance between transmitter and receiver increases, with the modelling of the radio energy of this ejaculation for as on the surface that spreads over celestial body.This spherical model refers to wireless power on receiver along with square reduction of this distance.Can come this simple POA model of refinement through the calibration that utilizes complicated more propagation model and on possible transmission website, transmit via test.

Based on network multichannel POA

This location technology that arrives at power uses the characteristics of physical environment to remove location of wireless devices.Radio transmits not by target reflection and absorption on the demand line to the road of receiver (perhaps network antenna or device antenna), causes multichannel to be disturbed.On receiver, the copy of the decay of a plurality of time delays of this transmission arrives at and is used for gathering.

This POA multichannel fingerprint technique uses the amplitude of the degraded signal of multichannel to go to characterize to receive signal to be used for the comparison with the known amplitude mode database that receives from certain calibrating position.

In order to adopt the multichannel fingerprint, the operator detects radio net (using the test transmission of on service area, carrying out with lattice) and is used for comparing after a while to set up the amplitude mode fingerprint database.Need detection periodically again to upgrade this database, to compensate by variation in the caused radio environment of seasonal variations and the perhaps influence in space of building in the zone of calibration.

Based on network PDOA

Arrive at difference power and need have the one-to-many arrangement of a plurality of sensors and individual transmitter or a plurality of transmitters and single-sensor.This transmitter power of PDOA Technology Need and sensing station are known (priori), make to amplify or the power measurement of decay detection on survey sensor local (to antenna and sensor).

Location technology based on equipment

Receiver or transceiver based on equipment are known with different titles: movement station (honeycomb), access point (wireless local access network), transponder (RFID), slave (bluetooth) or label (UWB).In system, owing to measured signal rises on network, based on the system's reception of equipment and the arrival time or the signal intensity of measuring-signal based on equipment.The calculating of this device location can be carried out on equipment, and perhaps the measuring-signal characteristic can be transmitted to the processing that server is used to add.

TOA based on equipment

The absolute time that a plurality of radio broadcastings are arrived on mobile receiver is used in TOA location based on equipment in synchronizing network.Because signal advances with known speed, this distance can by or on receiver, perhaps communicating by letter returns to network, and the arrival time of on server, calculating.Arrival time data from two transmitters are 2 points with the position constriction, and need go to resolve this accurate position from the data of the 3rd transmitter.This network base station be important synchronously.The inaccurate position estimation error that directly is converted in timing synchronously.Other the intrinsic source of error that can measure is included in antenna and the reaction time of cable on the network transmitter.

When (atomic) clock of superelevation degree of accuracy or GPS type radio time reference are realized property born and portability, be used for network transmitter and the receiver that the both locks onto common time standard based on the embodiment in the synchronizing network TOA of equipment possible future.When both have common timing when transmitter and receiver, can directly calculate the leap time, and confirm according to leap time and the light velocity should distance.

TDOA based on equipment

TDOA based on equipment is based on the signal of gathering on the mobile device from the network transmitter that distributes on the geography.Only if this transmitter also provides (directly perhaps via broadcasting) its position or transmitter site to be retained in the device memory; Otherwise this equipment can not directly be carried out the TDOA position estimation, but must the information of the signal correction of gathering be loaded to land side server.

This network cell site signal broadcasting needs transmitter and highly firm clock synchronization, perhaps need be between transmitter station difference in regularly be for being arranged on the wireless device, perhaps be arranged on position on the side server of land and confirm that engine knows.

Use is included in the forward link trilateration (EFLT) that is used as the medium degree of accuracy in CDMA (ansi standard IS-95, the IS-2000) network and retreats the AFLT of localization method (AFLT) and strengthen (both in ansi standard IS-801 by standardization) system based on the commercial positioning system of the TDOA of equipment.

Ultra broadband (UWB)

Operation provides definition and restriction to the part 15.503 of FCC rule for UWB.Ultra broadband is the embodiment in modern times that is used for the oldest technology of modulated radio signal (Marconi (Marconi) spark-gap transmitter).Pulse code modulation (PCM) is used to be coded in the data on the spread spectrum signal of broadband.

Radio ultra wide band system is uploaded feed signals in the frequency wideer than the radio communications system of routine, and normally is difficult to detect.By the amount of frequency spectrum that the UWB signal takies, that is, the bandwidth of UWB signal is 25% of centre frequency at least.Therefore, be the bandwidth that the UWB signal at center will have the minimum of 500MHz with 2GHz, and be that the bandwidth of minimum of the UWB signal at center will be 1GHz with 4GHz.The most common technology that is used to produce the UWB signal is to transmit pulse with the duration less than 1 nanosecond.

Use special broadband signal to go to transmit binary message, the UWB technology is useful for the location near (via POA), AoA, TDOA or these technological mixing.In theory, the degree of accuracy of TDOA estimation is the effects limit that receives some reality, such as integral time, signal to noise ratio (snr) on each receiving station, and the bandwidth of sending signal.The Cramer-Rao constraint illustrates this correlativity.It can be approximated to be:

${\mathrm{TDOA}}_{\mathrm{rms}}=\frac{1}{2\mathrm{\π}{f}_{\mathrm{rms}}\sqrt{2\mathrm{SbT}}}$

Here f _RmsBe the rms bandwidth of signal, b is the noise equivalent bandwidth of receiver, and T is integral time, and S is the less SNR of two websites.TDOA formulate lower limit.In practice, this system will handle and disturb and multichannel, and wherein the both trends towards limiting actual SNR.The UWB radiotelegraphy does not receive the influence of multichannel disturbing effect to a great extent, allows the coherence bandwidth of different multichannel compositions by the multiplex (MUX) of receiver parsing because the signal bandwidth of UWB signal is similar to.

The possible agency of the power that in UWB, is used to arrive is the use of signal bit rate.Owing to signal to noise ratio (snr) descends along with power increases, faster after certain point, reduce s/n in the increase of specific power ratings, thus still less throughput than in fact meaning bigger information entropy and leaving from Shannon capacity.Because the power of UWB signal is along with distance (from radiowave through air, and the decay of the combined influence of free space loss, plane earth attenuation and diffraction loss) reduces, the bit rate of maximum possible will increase and reduce along with distance.When restriction was used for range estimation, this bit rate (the perhaps bit error rate) can be as the approaching indication of perhaps leaving this wireless device.

With the simplest word, when the distance between transmitter and receiver increases, with the modelling of the radio energy of this ejaculation for as on the surface that spreads over celestial body.This spherical model refers to wireless power on receiver along with square reduction of this distance.Can come this simple model of refinement through the calibration that utilizes complicated more propagation model and on possible transmission website, transmit via test.
