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.

Drones are, in essence, flying autonomous vehicles. Pros & cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight, as are piloted airplanes? Is the technology advancing faster than we can answer the questions it poses?
