Abstract :
An advanced co-channel allocation system for use of 2.45 GHz multiple wireless gates in a train station has been developed. It is desirable to use a co-channel allocation system when designing a multiple gate system to effectively utilize frequency resources. The new co-channel allocation system doesn´t need to phase lock. Each transmitter has a highly stable oscillator. The installation cost of this co-channel operation system is lower than the old model which needs to phase lock. The interferences in a multiple wireless gate using this new co-channel system are discussed and compared with experimental results. The operation of advanced model has been successfully tested with the newly developed highly stable RLL DR oscillator.<>
