Description
Technical field
This utility model relates to a kind of mobile hot spot device, particularly open a kind of multimode LTE radio networking device.
Background technology
LTE(Long Term
Evolution, Long Term Evolution) it is the Long Term Evolution of the UMTS technical standard organized to set up by 3GPP, formally set up the project in December, 2004 3GPP Toronto TSG RAN#26 meeting and start.
His main feature has:
1, low network delay (little IP packet can have the delay less than 5ms under optimum condition), compare former wireless connect technology and have shorter handing-over and set up connection time.2, strengthen mobile status connect support, as acceptable terminal under different frequency ranges with under the translational speed of up to 350km/h or 500km/h use network service.3, download use OFDMA, upload use SC-FDMA to save electric power.Downlink resource includes frequency resource, time resource and space resources, the most existing frequency division multiplexing, has again time division multiplex, has again space division multiplexing.It is the least resource unit that can distribute to a user on downlink that ETSI TS 136 211 specification defines Resource Block Resource Block (LTE downlink).One Resource Block includes 12 subcarriers and continues the time of a time slot；One time slot 0.5 millisecond, contains 7 OFDM symbol (symbol)；And each OFDM symbol (symbol) occupies the frequency resource of 12 subcarriers.4, support that FDD (FDD) communicates with time division duplex (TDD), and accept to use the time-division half-duplex operation of same wireless connect technology.5, frequency range listed by all frequency ranges is supported.These frequency ranges are used in IMT-2000 specification by International Telecommunication Union's radio communication group.6, increasing frequency range motility, 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and 20MHz frequency bandwidth all can be applicable to network.And 5MHz is supported to cause this technology to there will be problem when spread overwide areas, because old standard such as 2G GSM and cdmaOne uses this frequency bandwidth equally by W-CDMA.7, support from covering the millimicro microstage base station (such as Home eNodeB and Picocell femto cell) of tens of meters to the Macrocell macrocell base stations covering 100 kilometers.Relatively low frequency range is used to provide for the suburb network coverage, and base station signal can provide perfect service in the coverage of 5 kilometers, can provide high-quality network service, and can provide the acceptable network service in 100 kilometers in 30 kilometers.In urban area, higher frequency range (such as the 2.6GHz in Europe) can be used for providing high-speed mobile broadband service.Under this frequency range, base station area coverage will be equally likely to or less than 1 kilometer.8, support that at least 200 active connections are connected into single 5MHz frequency bandwidth simultaneously.9, the network structure simplified: E-UTRA network is only made up of eNodeB.10, communication standard (such as GSM/EDGE, UMTS and CDMA2000) can be had with interactive operation and can coexist with them.User can carry out call in the area having LTE signal and data are transmitted, cdmaOne and the CDMA2000 network under LTE uncovered area can be directly switch into GSM/EDGE or based on W-CDMA UMTS even 3GPP2.11, packet switched wirelss interface is supported.12, support multicast/Broadcast Single Frequency network (MBSFN:
Multicast/Broadcast Single-frequency Network).This characteristic can use LTE network to provide the services such as such as mobile TV, is the competitor of DVB-H broadcast.
For meeting seriality and the international roaming demand of business after LTE introduces, multimode multi-frequency section termination will be market transition stage one inevitable choice.For operator, LTE not only requires after introducing that its terminal increases support LTE pattern and corresponding working frequency range on the basis of original multimode, also to increase the working frequency range that may insure that user realizes international roaming.
Present end product is all walking miniaturization, integrated direction, and like product the most on the market the most simply supports that single pattern works, or both of which, therefore brings obstacle in global roaming uses.Additionally portable product uses battery to power mostly, terminal volume can be caused excessive, lose portability.
