Feasibility Study for a GSM Private Cordless Base Station Based on Total Frequency Hopping
This paper continues addressing the problem of allocating frequencies in a GSM-based Private Cordless Base Station (PCBS) system introduced in  by the term of a GSM Home Base Station. Total Frequency Hopping (TFH) is presented in order to overcome the frequency allocation and the inter-PCBS synchronisation problems. The PCBS system will use the same frequency band as the overlaying GSM network and thus create more interference to it. Earlier simulations have revealed that the negative impact of the underlying PCBS system to the GSM network performance is minimal if the PCBS transmission power is low. In this paper we investigate if the PCBS system with low transmission power will actually itself be able to function despite the interference from the overlaying system. Furthermore, a simple way to synchronise to the frequency hopping BCCH is presented with time analysis.
