Alcatel-Lucent has come up with an interesting and perhaps game changing invention. It is a cell data transmitter that is roughly the size of an old Rubik's cube. The company has been able to put the technology for 2G, 3G and 4G networks together in one device so that cell phone companies can maximize coverage. Each cube covers about 2 city blocks. The cubes can be stacked for areas needing better bandwidth. They can also be installed almost anywhere, so this will be a great idea for college campuses and sports stadiums. They will also work well for rest stops and may actually encourage drivers to stop to use their smart phones as they will know they can get better coverage at the rest stop.
