The Standards Board Review Committee of the Institute of Electrical and Electronics Engineers earlier this month approved the 802.11g standard for wireless communications. An estimated 6 million users already have 802.11g devices.
The theoretical top rate for 802.11g is 54 Mbps, compared with 11 Mbps for the earlier 802.11b standard, making possible wireless applications such as streaming videoconferences.
There is a disadvantage to 11g, however: Its signals don't travel quite as far as 802.11b signals. In GCN Lab tests, 11g products normally became ineffective around 60 feet to 80 feet from a network access point in an office environment, whereas some 11b products' signals could reach beyond 120 feet.
