A radio frequency (RF) modem shelf for use in a fixed wireless access network comprising, a plurality of base stations capable of bidirectional time division duplex (TDD) communication with wireless access devices disposed at subscriber premises. The shelf comprises: a) a first RF modem for communicating with wireless access devices using TDD frames, each TDD frame having an uplink for, receiving data and a downlink for transmitting data; and b) a modulation controller associated with the RF modem shelf for determining an optimum modulation configuration for each of the wireless access devices communicating with the first RF modem. The controller causes the first RF modem to transmit downlink data to a first wireless access device in a first data block having a first optimum modulation configuration and to transmit downlink data to a second wireless access device in a second data block having a different second optimum modulation configuration.

Wireless access system using multiple modulation formats in TDD frames and method of operation

There is disclosed a radio frequency (RF) modem shelf for use in a fixed wireless access network comprising a plurality of base stations capable of bidirectional time division duplex (TDD) communication with wireless access devices disposed at a plurality of subscriber premises. The radio frequency (RF) modem shelf comprises: a) a first RF modem for communicating with a plurality of the wireless access devices using TDD frames, each TDD frame having an uplink for receiving data and a downlink for transmitting data; and b) a modulation controller associated with the RF modem shelf for determining an optimum modulation configuration for each of the plurality of wireless access devices communicating with the first RF modem. The modulation controller causes the first RF modem to transmit downlink data to a first wireless access device in a first data block having a first optimum modulation configuration and to transmit downlink data to a second wireless access device in a second data block having a different second optimum modulation configuration.

There is disclosed a TDD frame transmission synchronization apparatus for use in a fixed wireless access network comprising a plurality of base stations capable of bidirectional time division duplex (TDD) communication with wireless access devices disposed at a plurality of subscriber premises. The TDD frame transmission synchronization apparatus comprises a frame allocation controller for receiving from a first radio frequency (RF) modem shelf associated with a first base station access requests generated by a first group of wireless access devices communicating with the first base station and determining from traffic requirements associated with the access requests a time duration of a longest downlink portion of TDD frames used by a first one of a plurality of RF modems in the RF modem shelf to communicate with a first wireless access device. The frame allocation controller further determines a frame allocation of the downlink portion and the uplink portion of TDD frames used by the plurality of RF modems to communicate with the first group of wireless access devices.

Wireless access system for allocating and synchronizing uplink and downlink of TDD frames and method of operation

There is disclosed a radio frequency (RF) modem shelf for use in a fixed wireless access network comprising a plurality of base stations capable of bidirectional time division duplex (TDD) communication with wireless access devices disposed at a plurality of subscriber premises. The radio frequency (RF) modem shelf comprises: 1) a first RF modem capable of communicating with a plurality of the wireless access devices using TDD frames, each TDD frame having an uplink for receiving data and a downlink for transmitting data; and 2) a modulation controller associated with the RF modem shelf capable of determining an optimum modulation configuration for each of the plurality of wireless access devices communicating with the first RF modem, wherein the modulation controller causes the first RF modem to transmit first downlink data to a first wireless access device in a first data block having a first optimum modulation configuration and to transmit second downlink data to the first wireless access device in a second data block having a different second optimum modulation configuration.
