1. A wireless point-to-multipoint system for combining requests for bandwidth by a data source for transmission of data over a wireless network, comprising: a central node; and a scheduler coupled to the central node; wherein the scheduler receives bandwidth requests from one or more data sources, each bandwidth request having a data source identifier, a priority identifier, and an amount of required bandwidth, wherein the scheduler schedules each of the bandwidth requests in an order to be serviced based on the priority identifier associated with each bandwidth request and an order in which each bandwidth request was received, wherein the scheduler combines the amount of required bandwidth specified by each of the scheduled bandwidth requests having the same data source identifier into a data burst bandwidth, and wherein the central node grants each data burst bandwidth to a respective data source over the wireless network.
