Abstract:
A network interface card for providing an interface between a host and a wireless asynchronous transfer mode based communications network, which comprises:a controller means for controlling the network interface card;a memory means, connected to said controller means, for providing cell queue management and wherein said memory means is partitioned into a plurality of areas and data of a single type is stored within a given one of said plurality of areas;a cell formatter/deformatter means, connected to said memory means and a MODEM/radio means, for providing error checking on cells processed by the network interface card;a memory pointer processor means, connected to said cell formatter/deformatter means, for providing data movement functions such that said controller means is relieved of these data movement functions;a TDMA/TDD framer means, connected to said controller means, for synchronizing and delineating frames received by said network interface card;MODEM/radio means, connected to said controller means and said TDMA/TDD Framer means, for modulating and demodulating cells to be transmitted and received from said wireless asynchronous transfer mode communications network; andan antenna means, connected to said MODEM/radio means, for sending and receiving cells over said wireless asynchronous transfer mode communications network.
