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.

Cisco halts plant relocation plans News & Analysis 2/1/2002 Post a comment Cisco Systems has abandoned plans to merge its Bellshill and Cumbernauld plants near Glasgow into a new facility. The decision not to go ahead with the relocation spells the end of the promise of 200 extra jobs associated with the development.
Full fart framåt för Sectra News & Analysis 2/1/2002 Post a comment Sectra har under den senaste tiden rönt stora framgångar. Företaget har fått sitt genombrott på den norska marknaden inom digital röntgen. Bolagets avlyssningssäkra GSM-telefon, Tiger, har godkänts av NATO.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
