Patent ID: 7505483

Claim:
An apparatus for transmitting WPAN (Wireless Personal Area Network) MAC (Medium Access Control) frames, comprising: a transport frame management unit for creating MAC transport frames through transport frames if the transport frames are generated from an upper protocol and application layer unit, classifying, by kinds, the created MAC transport frames in a MAC layer, and managing the classified MAC transport frames by queues, wherein said kinds comprise beacon frames, asynchronous streams and isochronous streams; a first-stage transport frame storage unit for storing the transport frames under the management of the transport frame management unit; a first-stage transport frame control information storage unit for storing storage information about the transport frames under the management of the transport frame management unit; a transport memory control unit for transmitting the transport frames stored in the first-stage transport frame storage unit at a high speed; a second-stage transport frame storage unit for storing the transport frames read and transferred from the first-stage transport frame storage unit by the transport memory control unit; a second-stage transport frame control information storage unit for storing storage information about the transport frames read and transferred from the first-stage transport frame control information storage unit by the transport memory control unit; and a transport frame transmission unit for grasping a position of the corresponding frame through the storage information stored in the second-stage transport frame control information storage unit if a transmission time of the transport frames is determined, reading and transmitting the transport frames stored in the second-stage transport frame storage unit to a physical layer unit.
