A Network World columnist thinks voice over WLAN isn’t going to get far: He really states the obvious here: "It's likely that wireless VoIP in the enterprise will follow a similar adoption pattern as that of WLANs: for enterprises where it makes sense, it will be deployed. And for enterprises where it doesn't make sense, it won't."
Gee, do ya think?
The way that vendors are squabbling these days, he may be right that voice over WLAN won't get far though. I've been told by some system integrators that once Cisco came out with its Wi-Fi phone, it stopped cooperating with the entrenched voice over WLAN guys, like Symbol and SpectraLink. That has resulted in some very unhappy customers who have Cisco radios and another vendor's phones and a system that doesn’t work well. Nobody is going to want voice over WLAN if they hear those kinds of stories.
I think that voice over WLAN will be used first by traveling business users. They'll use softphones that let them make calls from their laptops or PDAs while on the road. If that works out well and enough people do it, they may begin to pressure IT departments to deploy a more robust service on campus.
