Frequency hopping plan with radio network synchronization
Dongjie Huang, J.J. Shi · 2006
It has been demonstrated that inter-site synchronization has the potential to significantly increase capacity in cellular networks based on GSM and EDGE. In combination with frequency reuse and fractional loading, synchronization reduces interference through intelligent allocation of frequency hopping parameters. This paper discusses frequency-planning strategies for synchronized GSM and EDGE networks. In addition, field trial results in a mature GSM market are presented. In particular, FLP 1/1 with synchronization is compared with an optimized ad-hoc plan in terms of voice quality and number of call drops.
