How to get backward compatibility in next gen WLANs News & Analysis 2/1/2002 Post a comment Designers of next-generation high-speed wireless LAN (WLAN) devices are primarily concerned with two issues: Which high-speed standard, 802.11a or the proposed 802.11g, will offer the best solution? And, how do they address backward compatibility with a legacy 802.11b infrastructure?
802.11g spec: Covering the basics News & Analysis 2/1/2002 Post a comment Adopted last November after a long and often-heated debate, the IEEE 802.11g draft standard extends data rates for 2.4-GHz wireless-LAN (WLAN) systems to 54 Mbits/second and provides backward compatibility with existing 802.11b (Wi-Fi) equipment.
WLAN vendors debate 802.11g spec, coexistence issues News & Analysis 2/1/2002 Post a comment Though security has been getting the lion's share of attention in discussions of wireless local-area and personal-area networking, it is, paradoxically, the easiest problem to fix through basic attention to keys and virtual private networking.
