1. A system for providing reliable data transmission, comprising:
a stationary receiver comprising:
a first hard-wired connection to a first network, the first network connected to a first access point of a radio cell, the first hard-wired connection configured to communicate to a device of a mobile user via a first wireless transmitter of the first access point;a second hard-wired connection to a second network, the second network separate from the first network and also connected to the first access point of the radio cell, the second hard-wired connection configured to communicate to the device of the mobile user via a second wireless transmitter of the first access point;a third hard-wired connection to a third network; anda redundancy box configured to selectively couple communications via the third hard-wired connection to one of the first hard-wired connection and second hard-wired connection. |
