The research on Repeater Coordination Based on band plan

  •  Jianyu Zheng    


It is very troublesome that repeaters could interfere with one another.So we need to coordinate them .In our paper, we flexibly use the technology CTCSS to avoid interfere and accommodate more simultaneous users with the least repeaters. Then we propose a mixed-frequency-band repeater networks consist of some single-frequency-point repeater networks. Secondly, considered that the causes and solutions of interference might occur in a repeater networks, we propose a "band plan" to reduce the "Multi-path" interference in frequency and phase.Then combined with the most efficient repeater networks, we apply our model for “band plan” into the plat area. According to some limiting conditions, we bring the reality datum into our repeater networks model to accommodate 1,000 simultaneous users , and conclude that the minimum of repeaters is 76. Finally, we apply our plan into the mountain area, when meeting some new circumstances there, we adjust our”band plan” and change the repeaters to make them without interfere.
