1、QUESTION ITU-R 238-1/5*, *, *Broadband wireless access systems for the mobile service(2006-2007)The ITU Radiocommunication Assembly,consideringa) that there is a need to provide broadband wireless access for mobile terminals in a varietyof environments;b) that it is desirable to recommend radio inte
2、rface standards for broadband wireless accesssystems operating in the mobile service;c) that it is desirable to identify the technical and operational requirements for broadbandwireless access systems operating in the mobile service;d) that in todays radiocommunications, mobile “broadband” services
3、provide similarcapabilities and experience, with the added benefit of mobility, as is available from widely-deployed wireline networks, such as cable modems and higher speed DSL, in particular whenreceiving and transmitting multiple media applications;e) that there are mobile systems currently in op
4、eration and also in development that providebroadband wireless access in various frequency bands;f) that information transfer methods based on asynchronous transfer mode (ATM) and internetprotocol (IP) are being used in broadband infrastructure;g) that standardization bodies are addressing the archi
5、tecture and technical features ofbroadband wireless access systems operating in the mobile service,notingthat studies on BWA are also performed in the context of IMT-2000 and systemsbeyond (see Question ITU-R 229/8),decides that the following Questions should be studied1 What are the technical and o
6、perational requirements for broadband wireless access systemsin the mobile service?2 What are the applicable radio interface standards for broadband wireless access systems inthe mobile service?3 What are the applicable antenna systems suitable for broadband wireless access systems inthe mobile serv
7、ice?4 What are the frequency sharing and/or compatibility criteria associated with BWA systemsoperating in the mobile service?_* Broadband wireless access is defined in Recommendation ITU-R F.1399.* This Question should be brought to the attention of ITU-D Study Group 2 and ITU-R Study Group 9.* Former Question ITU-R 238-1/8.- 2 -further decides1 that the results of the above studies should be included in one or more Recommendations,Reports, or Handbooks;2 the above studies should be completed by 2010.Category: C2
