Abstract

The present invention relates to a communication system and methods of use thereof. The system includes sets of complementary radios for transmitting and receiving signals to achieve high reliability and reduced costs. The sets of complementary radios are in wireless communication with each other. A new connection is made by selecting from amongst the complementary radios. Switching between complementary radios during a connection is also permitted. Optimized protocols and hardware for implementing the system are disclosed.
