NEW ORLEANS—Major carriers disagree on the commercial viability of public WLAN hot spots and, as such, are taking very different approaches to the market.
While companies such as Nextel Communications Inc. and Sprint PCS Group are taking a wait-and-see approach to 802.11b, or Wi-Fi, others such as Verizon Wireless Inc., AT&T Wireless Services Inc. and Cingular Wireless are moving ahead with new services. The latter moves are not surprising, considering the rapid rollouts of wireless LAN hot spots. Currently, there are some 3,000 commercial, pay-per-use WLANs deployed throughout the United States, the majority of which run on Wi-Fi.
