Free Air Point to Multi-point Optical Networks

So how about optical? Typical fixed radio wireless work at frequencies of 900MHz to 40GHz with typical bandwidth of 2MHz to 100MHz. 100MHz bandwidth can only supply about 800megabits of data over the entire area covered by the frequency. Optical systems operate at 600THz and theoretically can transmit nearly 3.6petabites/second as technology advances. Current technology works easily at 40gigabits or nearly about 1000 times more data than a typical 6MHz radio wireless point to multi-point system.

With the proper optics (much like found in a typical laser printer) a base station could be built that can do multi-point communications at 111 megabytes per degree. In a typical urban setting, this would provide wireless Internet access at costs much less than current radio systems.
