Wi-Fi Planet's Eric Griffith takes a look at DiVitas, a startup that's focused on putting enterprises in control of their own FMC (fixed/mobile convergence) services. That puts DiVitas up against most UMA (unlicensed mobile access) providers, who are keeping control of services in the hands of carriers, not enterprises.

"Our vision: designing and developing a new appliance for the enterprise that goes behind the firewall and meets campus mobility requirements, while also extending functions into the off-campus, cellular space, plus Wi-Fi hotspots and hotzones," says Rich Watson, the company's Director of Product Management.

"The DiVitas setup is pretty simple: install their server appliance on the company network and put a DiVitas software client on every voice handset supported by the company," Griffith writes, "The handsets can be Wi-Fi only, cellular only, or dual-mode with both. While Divitas works with all three, the real benefit obviously comes with the dual-mode units."

The company says their product will be both affordable and easy to install. "DiVitas sees 70 percent of employees tethered to phones on their desk," Griffith writes. "The plan is to set them free."
