摘要：
A frequency control apparatus and method for railway wireless communication are provided. The frequency control apparatus includes a variable frequency processor and a fixed frequency processor. The variable frequency processor selects an available variable frequency and wirelessly receives non-safety-related train running information from a base station at the selected variable frequency. The fixed frequency processor wirelessly receives safety-related train running information at a predetermined fixed frequency.
