| Abstract: | As a radio dispatching communication system, TETRA has been applied in urban rail transit. The design of strength of radio field has to meet special requirements due to complicated radio environment. The calculating model and design principle are proposed in this paper. A method based on field design is presented to reinforce the swith across sections and remove multipath infections so as to ensure credible dispatching and control functions and of optimization of TETRA. |
