  1. CDMA2000: Enhancing your fixed network with a new WLL concept Innovation Never Stops Huawei Technologies

  2. Problems for wired networks C.O • Higher investment (CAPEX) • equipment • cable expenses • construction expenses • Land rent • Longer deployment delays • Can’t fulfill market needs • Operation and maintenance (OPEX) • difficult adjustment • difficult maintenance, more workload • Impossible in certain areas • only where cables may arrive C.O C.O C.O

  3. BTS1 BTS2 Why WLL? • Lower investment • Transmission in the air, no need for cables • Less infrastructure • Less Land rent • Faster deployment • Flexible networking, easier adjustment • Meet the need of increasing markets • Convenient maintenance • Fewer site = fewer workload • Wider coverage • No physical obstacles • Easier coverage for remote areas • Easier Expansion • Coverage expansion (just add sites) • Capacity expansion (just add modules) • LE is no more limited by copper losses

  4. Product Maturity Vendors’ proprietary solutions Operators totally depend on one vendor specially for the users’ terminals Frequency availability usually limits the choices Low capacity per site due to spectral efficiency among others Operators need a big number of sites Limited coverage distance, due to technology limitations= More sites required, more complicated frequency planning Low speed data No evolution path Usual Problems in WLL technologies

  5. CDMA presents the solution1. A Mature Technology CDMA Surpasses 202 Million Global Subscribers 3G CDMA2000 applications reach up to 86 Million subscribers all over the world Source: CDG, March 2001 through March 2004

  6. BTS3606 BTS3612 PSTN PLMN ISDN Internet MSC/HLR iManagerTM M2000 SoftSite BSC/PCF/IWF iSite iSite CDMA presents the solution2a. Standard with Open interfaces Huawei CDMA2000 Solutions 1 2 SS7 PDSN/FA HA V5.2/ SS7/ R2 AAA Packet Domain Radio Access

  7. CDMA presents the solution2b. Abundant User Terminals ETS1000/1200/1500 ETS2000/2200/2500 • Huawei CDMA Fixed Terminals • CDMA2000 1X (450/800/1900 MHz) • Support reverse polarity/16kc/12kc pulse • High-quality voice call with 8/13kbps QCELP and 8kbps EVRC • Data capabilities up to 153.6kbps • POTS, CLIP, G3 FAX, circuit / packet data, payphone, etc. • Optional outdoor/indoor antenna

  8. 450MHz 800MHz 1900MHz 2100MHz 2.1GHz 800MHz CDMA presents the solution3. Multiple Working Frequency Band • Huawei supplies all system products in above frequency bands, including user terminals. • Today, huawei is leading the CDMA450 market.

  9. CDMA presents the solution4. Higher Capacity per site 1 CDMA2000 BTS in average configuration equals: 4 GSM BTS sites 4 Analog AMPS sites 20 DECT sites 30 PHS sites The capacity (Spectrum Efficiency) of CDMA2000 1x is6~7 timesof that in GSM, and 25~30 timesof that in PHS.

  10. GSM1800 CDMA450 IMT- 2000 GSM 900 CDMA presents the solution5. Wider Cell Coverage 450MHz has the Best Radio Propagation! • Assumption: • Cell load: 50％ • FER: 1% • Transmit power of BTS: 20W • Transmit power of MS: 200mW • Height of MS antenna: 1.5m • Height of BTS antenna : urban:30m, suburb and rural: 50m

  11. Video On Demand Internet Browsing Video meeting Online game Location Service CDMA presents the solution6. High Speed Data Solution • Circuit data service • Fax: G3 • Asynchronous data service: 9.6k or 14.4k • Packet data service • Max. Data rate: forward 153.6kbps, reverse 153.6kbps • VOD, web surfing, online game, … Fax

  12. CDMA presents the solution7. Clear Evolution Path CDMA2000 1X EV - DO 2.4Mbps/153.6kbps (Rel 0) 3.1Mbps/1.8Mbps (Rel A) CDMA2000 1X 153.6kbps(Rel 0) 307.2kbps(Rel A) Larger system capacity & hold time IS95A 9.6kbps /14.4kbps IS95B 76.8/115.2kbps CDMA2000 1X EV - DV 3.1Mbps /1.8Mbps 1995 1998 2001 2003 2005 To achieve the evolution from 1x to 1x EV-DO with Huawei equipment, the only hardware required is the EV-DO channel boards, all the rest is software upgrade thanks to Huawei’s broadband platform deployed in 1x.

  13. Leased Line Services B N A 1Mbps 64Kbps 256Kbps Cash Center Government CDMA WLL EV-DO 512Kbps 128Kbps Sonatrach University

  14. CDMA WLL 1X + EV-DO FWT FWT LAN + 1x + EV-DO = Enterprise Solution LAN 1 Mbps AP WLAN PBX • Extend the limit of coverage with LAN\PBX Enterprise (BNA)

  15. IP Backbone CDMA WLL EV-DO P S T N IP Phone FWT VOIP based on EV-DO

  16. About Huawei CDMA2000 Applications • CDMA solutions in over 30 countries, for over 40 operators • Network capacity of over 12 million subscribers • Leadingvendor for CDMA450 end-to-end solution • The first CDMA commercial network in Western Europe • World’s firstinternational roaming

  17. Conclusion • WLL is no more a sacrifice that fixed operators must accept in order to provide access to certain unreachable areas. WLL is no more an “Only Voice Services and low speed data solution”. • With CDMA, fixed operators can transparently provide their PSTN services to the users, as well as High Speed Data Services with rich contents and VAS. • With CDMA, operators can even provide ADSL like services using the EV-DO technology with up to 2.4Mbps. • CDMA allow the operator to consider Limited Mobility as an option to the user, as well as upgrade to full mobility in the future if required with minimum investment. • Huawei Technologies has put a special focus on different CDMA2000 technologies, and today provides complete end-to-end solutions including applications like LBS, PTT, Wireless PABX, Wireless IN…
