WiFi Phones

Product Round-Up


Voice over IP technology is no longer new, as evidenced by the increased rate of adoption in both business and consumer markets. Service providers of all sorts are rushing to add voice to their offerings, and hardware vendors are steadily growing their product lines.

The latest obsession has become mobility, which comes in many flavors, and productivity demands and improved wireless networking solutions have created a need for VoIP technology to also be extended to the wireless world. Being untethered from their desktops enables workers to be more effective, and the ability to access corporate wireless networks can dramatically decrease cellular calling costs, which has prompted many phone manufacturers to develop WiFi-enabled handsets. On the consumer side, the Skype phenomenon has also caused vendors to make similar products available for home and SOHO use, many of which have been specifically designed for user with Skype. Some of the handsets are relatively basic, while others offer SIP compatibility and many of the features users have come to enjoy — even demand — from their cellular devices.

With that in mind, this month’s product round-up features a selection of WiFienabled phones. These represent many of the products available to businesses and consumers, and we encourage you to use this list as a starting point for selecting the WiFi handset that is best suited to your specific needs and budget. There is also a selection of cellular/WiFi dual mode handsets available already, as the fixed/mobile convergence (FMC) movement gains traction. Those products will likely be covered in a later issue.
