Abstract

A system and method is disclosed for dynamically allocating bandwidth among devices connected to a short-range radio communication link, wherein the link possesses a maximum allowable bandwidth (Max) for all connection. As devices request connection to the link, each device transmits a CoD device class, and a bandwidth requirement for each device, wherein a weighted value is derived therefrom. The invention proceeds according to protocol by comparing the bandwidth of a requesting device to the Max value of the link. If the bandwidth requirement<Max, then the connection is allowed. As additional devices request connection, the bandwidth requirement values are added together and are compared to the Max value. If the sum<Max, then each device is allocated it's a specific value of bandwidth, along with additional bandwidth that is derived from et weighted value. If the sum>Max, the requesting connection is denied.
