A Frequency Reuse Scheme for GPRS Network

In this paper, a novel frequency reuse scheme, 2*6 reuse, is proposed for the GPRS network. The simulation results show that 2*6 reuse outperforms the 1*3 frequency reuse scheme, which is usually considered as optimal. Moreover, compared with recent proposals such as 3*3, and 2*2 reuse schemes, 2*6 demonstrates superior performance. For example, with 5 hopping transceivers in a cell and 29 hopping frequencies, the average overall cell area throughput enhancement over 1*3 reuse is about 40% for the 2*2 reuse, 55% for the 3*3 reuse and 85% for the 2*6 reuse. The 2*6 reuse scheme also provides the highest cell capacity. Importantly, that in contrast to other simulated reuse schemes, the 2*6 reuse brings the average throughput with CS3 coding scheme very close to the achievable maximum and provides good throughput even in remote locations within the cell
