Smart Personal Objects Technology devices are built on a brand new computing platform incubated in Microsoft Research (MSR). Microsoft worked with National Semiconductor to develop a chipset, which consists of an application chip and a tiny radio frequency receiver. The platform has been optimized for low power draw, miniaturization and low cost. To provide connectivity to SPOT devices, Microsoft created DirectBand, a set of radio technologies that enables the transmission of Web-based information to smart objects. DirectBand includes the custom radio receiver chip, a nationwide wide-area network based on FM subcarrier technology and new radio protocols created specifically to meet the unique communication requirements of smart objects. Content such as news, weather and sports information is broadcast to smart devices as wireless "channels." Subscribers can customize the channels and the information within each channel so they see only the information that is important and relevant to them. They establish their preferences by interacting with a simple SPOT device Web site from their PC. A personalized Web site makes the care and nurturing of multiple smart devices easy and convenient.
But will these devices work outside of US. From what I've read so far, only Japan features as another country where these devices will work. I am really eager to know whether these will work in India, since the chips that goes in these devices were designed at the National's design centre in Bangalore.
