AI summary

A system for extending coverage of a wireless Internet service by using a mobile communication network is provided. The system includes a wireless access point, a combiner, and a distributor. The combiner is connected to the wireless access point. The combiner includes a filter that isolates a signal band of a wireless Internet signal corresponding to the wireless access point and a signal band of a mobile communication signal corresponding to the mobile communication network. After isolation, the combiner outputs the wireless Internet signal or the mobile communication signal. The distributor is connected to the combiner and at least one antenna. The distributor receives the wireless Internet signal from the combiner and outputs the received wireless Internet signal via the antenna.
