A "3D" processor could make wireless communication more efficient according to scientists at the University of Florida. It could benefit both WiFi and cellular data services. One of the limitations of current WiFi tech is that it uses a "planar ... processor" to handle the wireless signal. Because these processors are (in practical terms) two-dimensional, they can only work with a limited range of wireless frequencies. Expanding the range of frequencies planar processors can handle is only possible by making them wider, a little like increasing capacity on roads. But making the ... (view more)

Microsoft wants to use unused TV frequencies to provide Internet service in rural areas. It believes its size could help bring down the costs of the technology. The system is known as white-spaces technology and uses wireless frequencies that are in ... the band reserved for over-the-air TV broadcasts but aren't currently being used. While Microsoft plans to use some of these frequencies, it wants the government to reserve at least three frequencies in each local area for use with the technology.
