11. Fixed Home Access:Nokia RoofTop Wireless BroadbandRouted Mesh Wireless Networks • Models the Internet • Each node is an IP router & becomes part of the infrastructure • Minimizes upfront infrastructure • Adds robustness with subscribers • Routing simplifies line of sight so coverage is practical in neighborhoods • Only needs line of sight to another node • Routes around obstacles • Adaptive intelligence self-configures and self-heals • Installation and operations are simple • Robust to changes and congestion Makes wireless broadband scaleable and efficient

12. Technology mature and chipsets available Already well down cost curve - market making factor Can be deployed internationally Licence-exempt 'anything goes' approach: but industry standards prevail Bluetooth and WLAN can co-exist with minor capacity degredation The impact in the longer term of other uses within this band, such ISM, FWA, etc, may lead to additional spectrum requirements Spectrum Issues: 2.4GHz 2.4GHz Band

13. Deployment at 2.4 GHz • Chosen band for both Bluetooth and WLAN products - set for major increase in usage • Attractive for global mass market • Used for personal / local communications but…... • Global solutions will emerge challenging existing regulation: • distinction of 'private / public' will blurr and should bedismantled for the future converging market • The impact in the longer term of other uses within this band, such ISM, FWA, etc, may lead to additional spectrum requirements

14. Nokia applauds the UK Govt. 5GHz consultation HAN's/WLAN/5GHz will be an essential component of the future converged world and the Global Mobile Information Society Potential to become a global frequency band, with global mass market - but not there yet Private and public operation should be allowed Support for WRC-2003 to harmonise the 5GHz band on a global basis is required Support outdoor use for FWA in part of 5GHz Spectrum Issues: 5.xGHz 5.xGHz Band

15. Deployment at 5 GHz • Multiple companies worldwide are in process of designing chipsets to support 5GHz deployment • Initial deployment of consumer level 5GHz solutions in 2002. Early adopters in 2001. • Deployment in US will be based on IEEE802.11a - should be allowed in Europe also • WLAN (Hiperlan 1 & 2, IEEE802.11a) standards should use the same spectrum, channel arrangements, and all conform to the ERC requirement of spreading and power control • Fixed Wireless Access devices should be allowed to use part of this band • Need dramatic cost reductions to rival 2.4GHz solutions in Home Area Networks.

18. Response to the Minister • HAN's / WLAN / Bluetooth are an essential component of the future converging world and the Global Mobile Information Society • The consultation on the ultilisation of the 5GHz band is applauded • The UK has a leading role to play in the ulitilisation of the 5GHz band and decisions taken on the use of this band should be as sustainable and future proof as possible and in the context of the global market • Regulation should reflect the market developments of the best effort 'internet' service paradigm and the removal of the distinction between 'public and private' • The planning of the 5GHz spectrum should be as detailed in table 1 (attached)
