`
`ABSTRACT
`
`A packet centric wireless point-to-multipoint (PtMP) tele(cid:173)
`communications system is provided. The telecommunica(cid:173)
`tions system includes a wireless network that provides for
`true QoS. A media access control (MAC) layer is used in a
`packet-centric wireless point to multi-point (PtMP) telecom(cid:173)
`munications
`system,
`the
`telecommunications
`system
`includes a wireless base station coupled to a first data
`network, one or more host workstations coupled to the first
`data network, one or more subscriber customer premise
`equipment (CPE) stations in wireless communication with
`the wireless base station over a shared bandwidth using a
`packet-centric protocol, and one or more subscriber work(cid:173)
`stations coupled to each of the subscriber CPE stations over
`a second network. The MAC layer includes a resource
`allocation means that allocates shared bandwidth among the
`subscriber CPE stations to optimize end-user quality of
`service (QoS).
