An apparatus, method and system are illustrated which provide a media access control polling protocol, using two types of polls, for packet data transmission in the uplink direction, in fixed wireless communication systems. The preferred system embodiment includes a plurality of subscriber units having transceivers for wireless communication, a base station having a transceiver for wireless communication with the plurality of subscriber units, and a data interface unit (DIU) operatively coupled to the base station through a network access controller. The DIU transmits a first poll, which authorizes transmission of a first predetermined amount of data, referred to as a standard allocation, for prompt throughput of small messages, such as acknowledgements. For subscriber units having additional data for transmission, the DIU transmits a second poll on a distinct or separate subchannel, which authorizes transmission of a second predetermined amount of data, referred to as an extended allocation, for transmission of larger blocks of data which are less delay-sensitive. In addition, power measurement is performed on all poll responses, to allow for transmission power level changes prior to and during data transmission, for greater data throughput.

In general, the SRM provides a network provider with visibility and control of its broadband network. A SRM connection manager receives setup signals to and from a subscriber and acts on them by analyzing the setup signals and by either comparing the setup signals to predefined rules, which are either static or dynamic, or modifying them. The access server provides intelligence to the SRM by verifying authentication information according to the connection manager's database and continuously updating the connection manager database for further modification of the subscriber's acquired session.
