IEEE 802.11a/b/g WiFi/WLAN MAC & WLAN PHY Layer IP Core

Overview

The IEEE 802.11a/b/g core is licensable independent WLAN PHY/physical Layer & WLAN MAC Layer Modem enables customers to develop cost effective Wireless LAN solution.The WLAN PHY Layer Core is developed in VHDL and fixed point DSP based C code as per the IEEE standard and it runs on any DSP and FPGA target and WLAN/WiFi MAC Layer runs on Microprocessor of ARM , Motorola and freescale etc. We can port the same any hardware platform with less effort.

The WLAN standard specifies the PHY for a higher data rate extension in the 2.4 GHz ISM band to the 802.11b standard and uses an Orthogonal Frequency Division Multiplexing (OFDM) modulation system similar to 802.11a.It supports the 802.11b specified data rates of 1, 2, 5.5 and 11 Mbps in DSSS/CCK modulation technique and also includes data rates of 6, 9, 12, 18, 24, 36, 48 and 54 Mbps using OFDM technology.
