Abstract:
1. A multi-tier communication system for providing wireless access to a portable wireless access device that is able to establish wireless links with the communication system by using at least two different communication protocols of which a first communication protocol having a different broadcast strength than said second communication protocol, said multi-tier system comprising: a. a first wireless communication network including a plurality of first gateways forming a low power tier for providing wireless services by establishing wireless communication links with one or more of the portable wireless access devices using said first communication protocol at a low broadcast strength operating over a small geographic area; b. a second wireless communication network including a plurality of second gateways forming a higher power tier for providing wireless services by establishing wireless communications with one or more of the portable wireless devices using said second communication protocol at a higher broadcast strength operating over a larger geographic area; and c. a system traffic controller configured to effect establishment of a wireless communication link between a first portable wireless access device and said first wireless communication network if said first wireless communication network is capable of providing a service requested by said first portable wireless access device, thereby achieving a more nearly optimal utilization of radio spectrum.
