US Patent 7477873 Wireless communication system and method for facilitating wireless communication

In a system and method for facilitating wireless communication between agents in a wireless network, each agent is equipped with an agent's device (10a, 10b) using a main wireless infrastructure (2) and a separate auxiliary wireless infrastructure (1). Initial contact between any first agent's device (10a) and any other agent's device (10b) is made within the auxiliary wireless infrastructure, whereas, once this initial contact has been established, all ensuing communications between the first agent's device (10a) and the other agent's device (10b) take place within the main wireless infrastructure.
