o Wi-Max e a desvalorização das rádios AM/FM

É a opinião (excertos) de Corey Deitz (a merecer boa atenção):

«One of the scenarios I see coming together is the devaluation of AM and FM radio stations as technologies like WiMax take hold (...) WiMax will help to migrate Internet Radio from desktops to autos and other portable devices. WiMax radio signals (carrying broadband content at 70 megabits per second) should initially have a range of 30 miles. So, theoretically, an Internet radio station made available through a WiMax transmitting station centered in the middle of any American city will have the power to easily cover a 60-mile circumference, easily providing enough reach to rival most AM and FM stations being measured by Arbitron. (...) So, when the time comes when any enterprising programmer can create an Internet radio station which has the reach potential of terrestrial AM and FM properties, what does that do to their value? Well, I’m no financial genius but it seems to me it lowers their value – substantially. Before Internet radio, satellite, cell phones, and podcasts, AM and FM stations were considered non-renewable resources. In other words: the radio spectrum could hold only so many and no more could be created. (...) But, Internet radio stations can operate on low overhead which means they can also take more chances in specialized programming. They do not need as big an audience as a terrestrial station to be successful. An Internet radio station also doesn’t need 12 minutes of commercials each hour to be profitable, like many AM and FM operations. (...)And, although much weight has been put on HD Radio as part of the future saving grace of AM and FM, at least one question arises: will HD Radio infrastructure outpace WiMax infrastructure – and even if it does, will it matter?»
