We also performed hands-on evaluations of these data services by sending one of our lab associates on the road with his laptop and a bag full of cellular data NICs, trying to get a feel for how effective these services are for notebook mobilization (see "Wireless on the Road,"). Finally, we took a stab at analyzing the leading converged PDA/phone devices that rely on embedded cellular data modems to put information in your hand (see "Are Smartphones Lagging Behind?").
We asked providers to describe their existing and planned data service infrastructures, specific options for connecting handheld devices and notebook computers to their networks, and pricing for these services. We also asked carriers to summarize their value-added data services, including application services and Web optimization. Finally, we delved into some connectivity and security issues, including IP addressing options, integrated security services, and the integration of carrier and enterprise networks.
We concluded that all the providers deliver viable enterprise data services, each with differentiators. However, we were disappointed by the lack of detail in most responses--with the exceptions of AT&T Wireless' and Nextel's replies--and an unwillingness to dedicate internal resources to follow-up inquiries, though in fairness to the vendors, we did hit them at the peak of summer vacation season. Still, we couldn't help but wonder why these vendors wouldn't jump at the opportunity to tell their stories to our readers. Finally, based on our analysis of the offerings and hands-on experience with these services, we came away with the impression that though today's services can deliver positive ROI for some organizations, performance must improve and prices must come down before broad deployment occurs. The magic numbers? We'd like to see several hundred Kbps of throughput and unlimited usage at less than $50 per month. According to our reader poll, you agree.
