1. A wireless network, comprising:
a centralized node; and
a plurality of remote nodes in communication with the centralized node via a wireless uplink channel and a wireless downlink channel;
wherein the wireless uplink channel carries data from the plurality of remote nodes to the centralized node and the wireless downlink channel carries data from the centralized node to the plurality of remote nodes, and
wherein the centralized node is configured to detect a silent period associated with voice communications received from one of the plurality of remote nodes over the uplink channel and to deactivate unsolicited grant service to the one of the plurality of remote nodes and not activate request polling responsive to the detection of the silent period.
