Abstract

A method for transmitting wireless signals from a plurality of wireless access points (AP) to a train is disclosed in this invention. The method includes a step of connecting a high speed wide-area local area network (WLAN) switch between a network and a multiplexed Ethernet fiber system for receiving and transmitting a plurality of Internet signals to the plurality of wireless access points (AP). The method further includes a step of implementing a wireless signal receiving and distribution system on the train for processing a roaming and handover from receiving the plurality of signals from one of the wireless access point to a next wireless access point. The method further includes a step of distributing the plurality of signals to a plurality of passenger-users traveling on the train.
