Abstract
Abstract An ad-hoc, peer-to-peer radio access system for cellular communications systems using time division duplex as a way of maximizing the bits/hz/km2 for cellular systems. The network architecture of the ad-hoc system allows the radio access to be integrated with the fixed components of a conventional cellular system, PSTN or ISP. The objective is to make the system of the invention transparent to the features and services provided by the external network. The advantages of such a system to a cellular operator are that significantly less infrastructure is required, and that the RF spectrum is more efficiently utilized resulting in much lower building and operating costs. The system architecture is comprised of remote terminals, routers, gateways, and at least one gateway controller that interfaces the ad-hoc system to a cellular network system. The ad-hoc system of the invention allows for both voice and data transmissions and receptions.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
265 words
An ad-hoc radio system comprising: a series of remote radio terminals each comprising a radio transceiver and a control processor, said control processor comprising software means for determining a routing path of a call, for communicating with other said radio terminals, and for establishing the respective said radio terminal as a hop for other said radio terminals during a call-connection; a plurality of gateways, each said gateway being in operative communication with at least some of said series of remote radio terminals; a gateway controller in operative communication with said plurality of gateways; said gateway controller comprising call control and routing means for directing calls to a destination, and interconnecting means for connecting said series of remote radio terminals to an external network, whereby originating calls from a said radio terminal may be directed to a destination serviced by the external network and calls originating from the external network may be directed to a said radio terminal; said call control and routing means comprising routing information means for directing an originating call from a said radio terminal via a said gateway to an external network, and for directing a call from an external network to a said radio terminal via a said gateway; and a plurality of wireless routers operatively connected between said series of remote terminals and said plurality of gateways for wirelessly interconnecting said series of radio terminals and for wirelessly interconnecting said series of radio terminals to said plurality of gateways, whereby said remote radio terminals may indirectly communicate with each other and said gateways through one or more said wireless routers.
Claim 2
Dependent Claim
