Wireless Internet telecommunications
Many people try to predict the future. Weather forecasters do it. Financial analysts do it. Science fiction writers do it. We make and change travel plans based upon weather forecasts. We buy and sell stocks based upon predictions of future performance from financial analysts. Science fiction writers have successfully predicted advances like travel to the moon, robots, and communication satellites. Success rates strongly depend on the bases...
