BTS18000 overviewFront page of manual Welcome screenUser’s help screenNortel Networks Confidential 1--1BTS18000 Reference ManualCopyright E2002--2004 Nortel Networks1 BTS18000 OVERVIEW1.1 Key market trends1.1.1 Operating expenses savingsMost of the operators in Europe and Asia are going to install UMTS equipment ontheir networks, including UMTS radio cabinets. In most of the cases, these radioequipments will be co--located with existing GSM sites.Moreover, as GSM capacity increases in urban areas (voice and data traffic),operators will need to install new radio transmitters and will be forced to limit thenumber of additional radio cabinets required to carry the increasing traffic, in orderto contain the ”floor investments” at an acceptable level.This results in a need for a Base Transceiver Station (BTS) solution with a highnumber of transceivers per square meter, thus a cabinet which can house more TRXsin the same footprint than S8000 and S12000 cabinets. This results as well in theneed for reduced power consumption, operational effectiveness, antenna towerloading.1.1.2 Advent of new technologiesThe existing GSM European operators are almost all planning the deployment ofa 3G networks based on UMTS technology. Some of them have even started in 2001but the massive deployment is just about to start.In Asia, the scenario is almost the same and the Asian operators are also preparingfor 3G (CDMA 2000 or UMTS).In the Americas, the path to 3G for GSM operators is likely to stop off atGPRS/EDGE in a first stage with limited infrastructure investment before investingmassively in 3G technology.The challenge for these operators is to increase the capacity and complete thecoverage of their GSM network while they are starting their investments in 3Ginfrastructure. This results into two major difficulties for the operators:Radio sites congestion.Most of the urban sites are highly constrained by BTS footprint and will hardlyaccommodate for both 3G and increased capacity GSM/GPRS base stations.Therefore, dense and compact GSM and UMTS product solutions are required toanswer to this constraint.

GSM radio sites will bereused. Some solutions, as dual mode UMTS/GSM base stations and/orinfrastructure sharing between 3G operators, will allow cost--effectivelylaunching UMTS services, before smoothly migrating the subscriber base fromGSM to UMTS.This results in a need for a BTS solution supporting both GSM and UMTS.1.1.3 Investment protectionMost of the GSM operators are facing the challenges to increase the capacity andcoverage of their existing networks as traffic is growing, and in the same time startto invest in new UMTS network elements and buy expensive licenses. As aconsequence, the protection of the operators’ existing investments while they investin new network components is becoming more and more important to preserve theirbusiness profitability.This results in a need for a BTS solution which should offer the maximum ofcompatibility with the existing S8000 and S12000 BTSs installed on the field (e.g.possibility to expand existing sites).1.1.4 Network coverageGSM coverage is not everywhere today and the GSM operators will complete thecoverage of their network in the coming years, mainly in not very dense and ruralareas.This results in the need for a very cost--effective, low capacity solution, offeringhigh coverage capabilities in order to limit the investment and balance the businesscase of the operator for the low revenue generating areas.
