[Overview of the work being carried out in ITU on Wireless Access Systems (WAS)]

  • [The work on Wireless Access Systems is being carried out by] - [Working Parties 8A] - [and] - [9B] - [, responsible for the mobile and fixed services aspects of WAS, respectively.]

[ITU-R Questions]
  • [Question ITU-R 212/8: Nomadic wireless access (NWA) systems, including RLANs for mobile applications]
  • [Question ITU-R 215/8: Frequency bands, technical characteristics, and operational requirements for FWA systems using mobile technology]
  • [Question ITU-R 140/9: Fixed Wireless Access (FWA) systems using mobile-derived technologies]
  • [Question ITU-R 142/9: Radio local area networks (RLANs)]
  • [Question ITU-R 220/9: FWA conveying IP packets or ATM cells]
  • [Question ITU-R 229/9: Frequency arrangements based on frequency blocks for systems in the fixed service]
[These studies can be categorized as follows:]

  • [1. Preferred frequency bands, spectrum requirements and frequency channelling plan.]
  • [2. Suitable technology for WAS.]
  • [3. System characteristics and operational requirements including interface to switched networks.]
  • [4. Performance and availability objectives.]
  • [5. Frequency sharing criteria, interference effects and service area boundary.]
  • [6. Radio local area networks (RLANs).]
