  • Distributed wireless transmission and reception system, and expanded wireless network
    Patent number: 9294183
    Abstract: The present invention relates to a distributed transmission and reception system, and an expanded wireless network. The distributed transmission and reception system according to one embodiment of the present invention comprises a distributed transmission system, a distributed reception system, and a distributed relay system. A source signal of a source radio is divided into a plurality of signals through the distributed transmission system, is relayed through an associate's radio, and can be distributed into and transmitted to other networks which are located out of a distance range. A destination radio positioned in another network can restore the original signal of the outgoing radio with the help of relay from the associate's radio via the distributed reception system. The associate's radio providing help in relay amplifies only a part of the source signal, and thus the intensity of the signal can be enhanced.
