(1)Wireless LAN 802.11b
he IEEE 802.11b specification builds on the original IEEE 802.11 standard by providing up to 11Mbps data rates in a direct sequence spread spectrum air interface using Barker codes for spreading 1 and 2 Mbps data rates and CCK modulation for 5.5Mbps and 11Mbps data rates. Nuntius has expertise in WLAN technologies and can provide solutions on multiple platforms. The diagram below shows an 802.11b solution that includes RF, analog baseband, digital baseband (with the PHY), and the MAC. For more information, contact Nuntius Systems, Inc.
