摘要
The present invention relates to a WLAN bridge device utilizing a TDMA / TDD MAC protocol and a method and system for implementing MAC using a software upgrade.;The present invention is to configure a wireless relay link using a first wireless LAN bridge (hereinafter referred to as a "master") connected to an IP core network, a plurality of second wireless LAN bridge (hereinafter referred to as "slave") connected to a base station In one embodiment, the master and the slave transmit and receive an RF signal, and perform an orthogonal frequency division multiplexing (OFDM) modem / radio frequency (RF) module for encoding or decoding an RF signal according to a WLAN physical layer standard. ; Process the information of the physical layer decoded by the OFDM modem / RF module to form a medium access control (MAC) frame of a time division multiple access (TDMA) / time division duplex (TDD) scheme, and then transmit to a higher layer or the upper layer A TDMA MAC module configured to convert the TDMA / TDD MAC frame received from the physical layer into information of the physical layer and transmit the information to the OFDM modem / RF module; And a network interface module configured to process data transmitted and received between the IP core network and the master or between the base station and the slave, and to process a response to a ping request and a Simple Network Management Protocol (SNMP) message. Provided is a WLAN bridge device utilizing a MAC protocol of the TDMA / TDD scheme.;According to the present invention, it is possible to provide a higher data rate and stability than the conventional WLAN bridge technology, and there is an effect of smoothly transmitting a large amount of traffic. In addition, it can contribute to improving service quality for wireless Internet users, including public wireless LAN or Wibro, and reducing service provider's network construction cost.;WLAN, Bridge, TDMA, TDD, MAC, Protocol, FPGA, VHDL
