Abstract:
1. An apparatus for transmitting WPAN (Wireless Personal Area Network) MAC (Medium Access Control) frames, comprising: a transport frame management unit for 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.
