The new 802.11g wireless networking specification, which Apple utilizes in its AirPort Extreme products, is helping to maintain strong growth in the Wi-Fi industry, according to a research report. The Dell’Oro Group released a report Wednesday indicating that “sales in the second quarter of products based on the new 802.11g standard are more than making up for a decline in revenue from 802.11b-based products,” according to CNET News.com. Overall shipments of 802.11 products grew 6 percent in the second quarter compared with the first, while revenue increased 2 percent to $419 million.
