The correct answer is False. W-CDMA does not require a complete change of RF equipment at each base station. In fact, W-CDMA can be deployed in a variety of ways, including using existing GSM base stations with minor modifications. This makes W-CDMA a cost-effective option for operators looking to upgrade their networks.
W-CDMA is a third-generation (3G) cellular technology that was developed by the Third Generation Partnership Project (3GPP). It is a wideband code division multiple access (WCDMA) system that uses a spread spectrum technique to allow multiple users to share the same radio frequency (RF) spectrum. W-CDMA is a more efficient use of RF spectrum than previous cellular technologies, such as GSM, and it offers a number of advantages, including higher data rates, better voice quality, and greater capacity.
W-CDMA can be deployed in a variety of ways. One option is to use new W-CDMA base stations. This is the most expensive option, but it offers the best performance. Another option is to use existing GSM base stations with minor modifications. This is a more cost-effective option, but it does not offer the same performance as using new W-CDMA base stations. A third option is to use a combination of new W-CDMA base stations and modified GSM base stations. This is a middle-ground option that offers a balance between performance and cost.
The choice of which deployment option to use depends on a number of factors, including the operator’s budget, the coverage requirements, and the traffic load. In general, new W-CDMA base stations are the best option for operators with high traffic loads and demanding coverage requirements. Modified GSM base stations are a good option for operators with lower traffic loads and less demanding coverage requirements. A combination of new W-CDMA base stations and modified GSM base stations is a good option for operators with intermediate traffic loads and coverage requirements.
