In a recent column on HomePlug's future (see link below) I said the demise of the Consumer Electronics Association's (CEA) rival powerline specification R7.3 left ITRAN's future unclear. Not true. The Israeli powerline chip maker has a lot going on, including a deal with Microsoft that actually helps clarify the giant's fuzzy digital home strategy.

Two years ago, ITRAN failed to convince the HomePlug Alliance its technology was superior to Intellon's. It then joined the CEA to help develop the R 7.3 specification, a process beset by delays and bad timing, ending in failure. But today, when HomePlug is fighting hard to compete against wireless in the high-speed PC networking space, ITRAN is poised for success in command and control, an arena with few competitors and where wireless is inappropriate.

Last month, ITRAN announced a new development platform for its IT800SCP chip. The technology is a collaboration between ITRAN and Microsoft that implements ITRAN's IT800 powerline command/control transceiver and Microsoft's Simple Control Protocol (SCP) in a single system. Using these tools, developers can network lightweight devices such as appliances, light switches and alarm clocks. In essence, SCP extends Universal Plug and Play (UPnP) to devices that don't have the processing power to handle TCP/IP traffic. ITRAN's technology transmits data at 7.5K bit/sec, a far cry from HomePlug's 14M bit/sec rated speeds, but perfect for networking low-power consumer electronics and white goods such as washing machines.

If you've never heard of SCP, you're not alone. But it's a key piece (along with UPnP) of what Microsoft will use to connect all our home devices, including its Tablet PCs and Smart Display. (For a white paper on the technology, see link below.)

"The more devices Microsoft can put its operating systems on, the more licensing revenue it will earn," says In-Stat analyst Jaclynn Bumback. Microsoft's short-term vision is to extend the PC's reach into entertainment with the Smart Display. With it, you can carry the device around the home to control whatever you have programmed into your PC (play music, view pictures, etc.) Eventually Microsoft will use the PC for home control using UPnP and SCP as its backbone, Bumback says.
