Voice over IP over Wi-Fi continues to show promise: Two stories today, one in NetworkWorldFusion on VoIP in the mud and Vocera in the hospital and the other, a baffling press release from Motorola and NEC full of marketing buzz about WLANs, cellular, and VoIP.
The former story describes a mining camp in Laos being set up with VoIP and a satellite dish as the only reasonable way to run communications. (Previous generations would have settled for walkie-talkies.) NWFusion also writes about Vocera's introduction into a hospital -- Vocera has a nifty communicator device for telephony that ties right in WLAN systems.
The Motorola and NEC announcement seems to be the intent to work together, but not an actual product. They'll develop some combo system that can handle cellular and Wi-Fi while providing VoIP, all in a single handset. Or so I think when I cast away the marketing phrases and jargon.
