You don't really disagree. Obviously, the smart radio, perhaps controlled through the new Xilinx SRAM processors, instantly programmable in Java over the net, is not yet feasible for mass use in PCS. I am outlining a goal for the industry to be achieved step by step through the extension of unlicensed spectrum, such as the ISM band today, with bandwidth insulated spacially as well as by codes and frequencies. Today, for example, the bottom end of the spectrum accommodates millions of cordless phones, garage door openers, AM radio stations, and other transmissions without crippling interference. As Moore's Law proceeds, this solution will become ever more widely applicable. In the next few years, when practically everyone totes pdQs around the globe, and Qualcomm buys a floundering Ericsson, some such frequency agile mode will become mandatory. |
