Abstract:
System manufacturers that provide wireless telecommunications equipment to cellular operators, often do not manufacture their own transceivers. They get their own supplies from various base station power amplifier vendors. Unfortunately cellular operators and system providers take design considerations of those primary power amplifiers for granted. The consequences are: Operators are overpaying for base station amplifiers to meet power and capacity demands. Base stations are complicated systems and the optimum technical design considerations of the power amplifier sub-systems have a major impact on multi-carrier Code Division Multiple Access (CDMA) Base Transceiver Station (BTS) performance. This paper discusses those power amplifier vendor claims, demonstrates design considerations and economic design solutions of consequent savings for the operator, based on a realistic market case. We realize that upfront savings, in power amplifier units, in a US market of approximately 550 multi
carrier basestation sectors would exceed $ 10 M.
