SPOTLIGHT: Nifty technologies, unproven ROI

VoWiFi is a potentially more reliable, flexible and cheaper alternative to cellular networks for making wireless phone calls within buildings. Dual-mode handsets will even let someone pass from a WiFi network onto a cellular one without dropping a call. That could mean mobile workers will not need a desk phone, since a cell phone shifts to the office network once on campus. Nifty technologies, but how many businesses will see the pay-back to justify building out a WiFi infrastructure and investing in the handsets? The guess of this analyst is that, for the next few years at least, only a minority of businesses will do so. Analysis
