Swedish-Finnish telecom company TeliaSonera has started selling hybrid phones that will automatically make phone calls via the Internet when in range of a WiFi hotspot, and use the normal cellphone network when not in a hotspot. Some other dual mode phones have been available, but this is the first phone (manufactured by Samsung) that will switch automatically between the two. The firm is targeting in home use first, which is clever, because we make a lot of calls from home. If you have a wireless router in your house, the phone will automatically make VoIP calls, saving money.
Devices like this illustrate the need to design communitywide broadband networks that offer BOTH fiber and wireless connectivity. We are going to want and need both, and communities should plan and design for both.
