GGSN SGSN MGW PCRF SAE GW HSS OCS MME/UPE WiMAX or LTE = Same Level of Upgrade 2G, 3G Network (GSM, EV-DO, HSPA) 2G, 3G Core Network Upgrade core network to support more IP data traffic New data overlay network 4G Network: (WiMAX or LTE) All IP Core Radio Access Network (RAN): > 90-95% of new CapEx* Core Network Equipment < 10% of new CapEx* Both WiMAX & LTE require new RAN equipment & devices. Neither is “backward compatible” to 3G. Both can interwork well with existing 2G, 3G networks. * Intel estimates. Percentage varies based upon the operator’s existing network.

  5. Future Data Rate & Latency Comparisons of WiMAX and 3G Evolution Today

  6. WiMAX Direct Impact on 3G PC Modem Pricing Wireless Notebook Modem ASP Trajectory $150 Since Intel came out with Echo Peak 2.5-3G Cellular $111 ASP* 3 Chip .11N+.16E Single Chip .11N+.16E** WiFi .11ABG WiFi .11N $0 2006 2007 2008 2009 2010 *ABI Research, Q3’07 preliminary ** Intel Estimates

  7. Mobile WiMAX™ 2.0 (802.16m)300+ Mbps (2010/2011) 7 * Note: Actual mobility & throughput depends on environmental conditions and Service Provider provisioning. Aggregate peak sector throughput calculated using 20 MHz for DL. FDD support in 2010 Peak sector throughput over 300 Mbps DL* (in 20 MHz) TDD & FDD support Multi-carrier support; BW of up to 100 MHz Increased VoIP capacity Even lower link access latencies Enhanced coverage Enhanced multi-radio coexistence and inter-technology handover Integrated multi-hop relay Self-organizing base stations Increased mobility: Up to 350 km/hr*

  8. IEEE 802.16m Backward Compatibility • 802.16e/802.16m Mixed • Operate on the same RF carrier with same/different BW (a) • Support a mix of 16e & 16m MS on same RF carrier (c and e) • .16e MS same performance as16e BS (b=c) • .16m BS support handover of .16e MS to/from.16e BS (b   c) • .16m MS operate with .16e BS with same performance as.16e MS (b=d) • .16m able to disable legacy support for e WiMAX Release 2.0 (16m) will be tightly backward compatible to release 1.0 (16e) 8
