Splintering Wireless Landscape? Is it just me or is not the wireless landscape in the U.S. becoming more and more splintered technology/compatibility wise as far as roaming coverage goes? Not so long ago we had 850 cellular and 1900 PCS. Most platforms other than the handful of GSM operators and iDEN were CDMA or TDMA with backup capability on AMPS, which was universally available on 850 nationwide. Now, we mostly have a mix of CDMA and GSM that not only don't mingle, but AMPS is going away as well. In addition, we have a proliferation of new bands (800 ESMR, 1700/2100 AWS, 700 Mhz, 2500 MHz.....) that will not be common to all carriers and devices, nor will they have compatible technologoes deployed on them in most cases. The combination of supported bands and corresponding technologies will be unique to each carrier's phone lineup. I don't know, but are we moving into an era where universal roaming coverage will be worse than it was not that long ago? Or do we put our hopes in multimode chipsets and hope that phones with those chipset make it to market?
