Voice over Wi-Fi growing, Eliminating wireline phones

Voice over Wi-Fi is growing, as predicted, since (a) Operators are happy to offload voice and especially data and, with Operator permission, the (b)Mobile phone manufacturers are building it into their (smart)phone platforms. This is part of the wider solution that Operators are employing to manage the deluge of data swamping their networks (see other articles for more details on how Operators are offloading mobile data to manage the exponential growth that they are experiencing, to prevent their Mobile Internet business from being broken).

UMA is the buzzword: enables Voice connections (transparent to the User) using available Wi-Fi connections. UMA is a piece of software that is built into the phone. It is a lot easier to use than a separate Voice over IP apps that must be installed and configured by the user, and that requires the user to have a IP data plan.

BlackBerry already has UMA  across their model line, and Android may offer it (there are rumors that this is being tested; see petition requesting it). Apple iPhone has Wi-Fi but does not yet include UMA, but it could easily (perhaps we’ll see it in a future release).

UMA can deliver significant savings of $500/year or more, by eliminating a landline phone and allowing the user to solely use their mobile phone. It’s the equivalent of replacing your landline phone by solely using your cellphone (than can also save you up to $1,000/year, surprisingly), but the Operator typically encourages this and includes it at little/no cost! You get free voice in the Home/Office! One can save a lot on International Roaming and Long Distance charges, too, since UMA calls are routed over Wi-Fi back to the Home network, and appear (and are billed) as local calls–as if you were calling from your home/office. In actual use, we found that “Road warriors” could save up to $1,000/month by using a UMA device (such as a BlackBerry) to make calls over Wi-Fi while traveling.
