Fixed Broadband Wireless Networks

2. Fixed Broadband Wireless Networks Innovations that will make fixed wireless a consumer option Lauren Hipp Nokia

3. Agenda • The Local Loop • Wireless alternatives • Self-configuring, wireless mesh networks

4. The Internet “Edge” The Last Mile is the toughest Internet infrastructure to provide • e-Business is accelerating the need for high speed access • Existing infrastructure doesn’t provide the speed and/or reach •Increased competition is driving down revenues and squeezing profits • the cost model for new infrastructure is changing • carriers are playing catch-up • The best solution varies, depending on cost and/or geographical reach

5. Dial-Up xDSL ISDN T1/E1 Service Provider The Internet “Edge” Wireless provides fast, affordable solutions that ANYONE can deploy

6. Wireless Local Loops Unlicensed wireless represents the only means for communication between two sites without having to pay a tariff or usage fee for use of the network Wireless local loop networks “cut” the line fees associated with carrier solutions Service providers capture 100% of the revenue

7. Types of Wireless Solutions • Traditional wireless solutions use Point-to-Point or newer Point-to-Multipoint solutions • Last hop access solutions • Limited to line of sight • Base station / client architecture • New multihop technology allows service providers to extend their reach to a greater number of customers • Creates routed mesh networks that model the Internet

8. Corporate Corporate Building the Wireless Internet • Internet Core: Fixed • High speed fixed access points • Wired DS3+ to Core • Metropolitan Area: High Speed Edge • RF engineered PTP/PIMP links • Unlicensed or licensed (LMDS) RF • The best solution varies for each customer segment. • A combination is needed to serve the whole market. • Neighborhoods: Ad-hoc Routed Mesh • Unlicensed spectrum

9. Components of Wireless Internet Point-to-Point Networks • A dedicated link between two nodes • Each customer requires a radio at the base station and a CPE radio • Highest performance solution -- well suited for high speed dedicated access and backhaul links

10. Components of Wireless Internet Point-to-Multipoint • A shared link between the base station radio and multiple CPE radios • CPE radios must have direct line of sight to the access point • Coverage limited to a single hop • Easier to deploy -- well suited for small networks and backhaul links

11. Components of Wireless Internet • Multipoint-to-Multipoint • The only way to affordably reach mass markets • Creates a wireless mesh -- just like the Internet • More than an access network -- each node is part of the infrastructure, routing date through the network • Line of sight problems are simplified • Networks scale

12. Wireless Mesh Local Loop • Total system economics must consider several components: • Up front investment • Demand driven deployability • Long term operational costs • Complexity of adds, moves, and changes • Robustness to interference and congestion • Actual price/performance of the solution • Density and scalability • Spectrum efficiency

13. Wireless Mesh Local Loops • Packet switched high speed data • Symmetric, high burst bandwidth • Always-on connectivity • Adaptive, Self-configuring, Multihop • Mitigates line-of-sight and extends POP reach • Self-configuring, self-healing  low cost operations • Adaptive cell-size for bandwidth scaling • Competitive position compared to alternatives • Competitive, independent solution against ISDN/DSL today • 3-5 year price/perf improvement is steep • Clear competitive edge where no high-speed wired infrastructure • Scalable, cost effective to deploy, manage and upgrade

14. Building the Wireless Internet Wireless Internet access is just getting started: • More reach • More bandwidth • More competitive options for service providers.
