ITU-R M.1801-2 1 RECOMMENDATION ITU-R M.1801-2*Radio interface standards for broadband wireless access systems, in
9、cluding mobile and nomadic applications, in the mobile service operating below 6 GHz (Questions ITU-R 212-4/5 and ITU-R 238-2/5) (2007-2010-2013) 1 Introduction This Recommendation recommends specific standards for broadband wireless access1in the mobile service. These specific standards are compose
10、d of common specifications developed by standards development organizations (SDOs). Using this Recommendation, manufacturers and operators should be able to determine the most suitable standards for their needs. These standards support a wide range of applications in urban, suburban and rural areas
11、for both generic broadband Internet data and real-time data, including applications such as voice and videoconferencing. 2 Scope This Recommendation identifies specific radio interface standards for BWA systems in the mobile service operating below 6 GHz. The standards included in this Recommendatio
12、n are capable of supporting users at broadband data rates, taking into account the ITU-R definitions of “wireless access” and “broadband wireless access” found in Recommendation ITU-R F.13992. This Recommendation is not intended to deal with the identification of suitable frequency bands for BWA sys
13、tems, nor with any regulatory issues. 3 Related ITU Recommendations The existing Recommendations that are considered to be of importance in the development of this particular Recommendation are as follows: Recommendation ITU-R F.1399 Vocabulary of terms for wireless access.

ITU-R M.1801-2 5 WWINA Wireless wideband Internet access XGP eXtended Global Platform 5 Noting Recommendation ITU-R F.1763 recommends radio interface standards for broadband wireless access systems in the fixed service operating below 66 GHz. The ITU
29、Radiocommunication Assembly, recommends that the radio interface standards in Annexes 1 to 8 should be used for BWA systems in the mobile service operating below 6 GHz. NOTE 1 Annex 9 provides a summary of the characteristics of the standards found in Annexes 1 to 8. Annex 1 Broadband radio local ar
30、ea networks Radio local area networks (RLANs) offer an extension to wired LANs utilizing radio as the connective media. They have applications in commercial environments where there may be considerable savings in both cost and time to install a network; in domestic environments where they provide ch
31、eap, flexible, connectivity to multiple computers used in the home; and in campus and public environments where the increasing use of portable computers, for both business and personal use, while travelling and due to the increase in flexible working practices, e.g., nomadic workers using laptop per
32、sonal computers not just in the office and at home, but in hotels, conference centres, airports, trains, planes and automobiles. In summary, they are intended mainly for nomadic wireless access applications, with respect to the access point (i.e. when the user is in a moving vehicle, the access poin
33、t is also in the vehicle). Broadband radio local area network standards are included in Recommendation ITU-R M.1450, and can be grouped as follows: IEEE 802.11 ETSI BRAN HIPERLAN ARIB HiSWANa. 1 IEEE 802.11 The IEEE 802.11 Working Group has developed a standard for RLANs, IEEE Std 802.11-2012, which
34、 is part of the IEEE 802 series of standards for local and metropolitan area networks. The medium access control (MAC) unit in IEEE Std 802.11 is designed to support physical layer units as they may be adopted dependent on the availability of spectrum. IEEE Std 802.11 operates in the 2 400-2 500 MHz
35、 band and in the bands comprising 3 650-3 700 MHz, 4.94-4.99 GHz, 5.03-5.091 GHz, 5.15-5.25 GHz, 5.25-5.35 GHz, 5.47-5.725 GHz and 5.725-5.850 GHz. 6 Rec. ITU-R M.1801-2 IEEE Std 802.11 employs the frequency hopping spread spectrum (FHSS) technique, direct sequence spread spectrum (DSSS) technique,
36、orthogonal frequency division multiplexing (OFDM) technique, and multiple input and multiple output (MIMO) technique. Approved amendments to the IEEE 802.11-2012 base standard include Prioritization of Management Frames (IEEE 802.11ae), and Robust Audio Video Streaming (IEEE 802.11aa). The URL for t
37、he IEEE 802.11 Working Group is http:/www.ieee802.org/11. IEEE Std 802.11-2012 and some amendments are available at no cost through the Get IEEE 802 program at http:/standards.ieee.org/about/get, and future amendments will become available for no cost six months after publication. Approved amendment
38、s and some draft amendments are available for purchase at http:/ 2 ETSI BRAN HIPERLAN The HiperLAN 2 specifications were developed by ETSI TC (Technical Committee) BRAN (broadband radio access networks). HiperLAN 2 is a flexible RLAN standard, designed to provide high-speed access up to 54 Mbit/s at
39、 physical layer (PHY) to a variety of networks including Internet protocol (IP) based networks typically used for RLAN systems. Convergence layers are specified which provide interworking with Ethernet, IEEE 1394 and ATM. Basic applications include data, voice and video, with specific quality-of-ser
40、vice parameters taken into account. HiperLAN 2 systems can be deployed in offices, classrooms, homes, factories, hot spot areas such as exhibition halls and, more generally, where radio transmission is an efficient alternative or complements wired technology. HiperLAN 2 is designed to operate in the
41、 bands 5.15-5.25 GHz, 5.25-5.35 GHz and 5.47-5.725 GHz. The core specifications are TS 101 475 (physical layer), TS 101 761 (data link control layer), and TS 101 493 (convergence layers). All ETSI standards are available in electronic form at: http:/pda.etsi.org/pda/queryform.asp, by specifying the
42、standard number in the search box. ETSI TC BRAN has also developed conformance test specifications for the core HIPERLAN 2 standards, to assure the interoperability of devices and products produced by different vendors. The test specifications include both radio and protocol testing. ETSI TC BRAN ha
43、s worked closely with IEEE-SA (Working Group 802.11) and with MMAC in Japan (Working Group High Speed Wireless Access Networks) to harmonize the systems developed by these three fora for the 5 GHz bands. 3 MMAC3HSWA4MMAC HSWA has developed and ARIB5has approved and published a standard for broadband
44、 mobile access communication systems. It is called HiSWANa (ARIB STD-T70). The scope of the technical specifications is limited to the air interface, the service interfaces of the wireless subsystem, the convergence layer functions and supporting capabilities required to realize the services. The te
45、chnical specifications describe the PHY and MAC/DLC layers, which are core network independent, and the core network-specific convergence layer. The typical data rate is from 6 to 3Multimedia Mobile Access Communication Systems Promotion Council (now called “Multimedia Mobile Access Communication Sy

The OFDM technique and TDMA-TDD scheme are used. It is capable of supporting multimedia applications by providing mechanisms to handle the quality-o
47、f-service (QoS). Restricted user mobility is supported within the local service area. Currently, only Ethernet service is supported. The HiSWANa system is operated in the 5 GHz bands (4.9-5.0 GHz and 5.15-5.25 GHz). Annex 2 IMT-2000 terrestrial radio interfaces The section titles are taken from 5 of
48、 Recommendation ITU-R M.1457, additional updated information can be found there. 1 IMT-2000 CDMA Direct Spread6The UTRAN radio-access scheme is direct-sequence CDMA (DS-CDMA) with information spread over approximately 5 MHz bandwidth using a chip rate of 3.84 Mchip/s. Higher order modulation (64-QAM
49、 in downlink and 16-QAM in uplink), multiple input multiple output antennas (MIMO), improved L2 support for high data rates and coding techniques (turbo codes) are used to provide high-speed packet access. A 10 ms radio frame is divided into 15 slots (2 560 chip/slot at the chip rate of 3.84 Mchip/s). A physical channel is therefore defined as a code (or number of codes). For HS-DSCH (high-speed downlink packet access HSDPA), E-DCH (high-speed uplink packet access HSUPA) and associated signalling channels, 2 ms subframes consisti
