Some of the first products based on 802.11n show the wireless standards performance potential—and problems. During eWEEK Labs tests, Linksys products based on Version 1.0 of the 802.11n draft standard were, indeed, fast—faster than anything weve tested to date—but issues involving range and interference with legacy wireless networks show room for improvement. The IEEE 802.11n […]

Ordinarily, we conduct wireless throughput testing in our West Coast offices, intentionally subjecting wireless products to the crowded radio frequency environment that is downtown San Francisco.

On April 6, the city of San Francisco announced it will pursue the bid presented by EarthLink and Google to provide citywide Wi-Fi services for residents and visitors alike. While the joint proposal offers both paid and free tiers of service, what is painfully obvious is that advertising will play a significant role for both […]
