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

HUAWEI 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

HUAWEI 3 Why WLL? BTS2 BTS1  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

HUAWEI 4 Usual Problems in WLL technologies 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

HUAWEI 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…
