ReFLEX
        The SkyTel ReFLEX 2Way data network provides reliable and secure wireless
          connectivity for collecting and using data from fixed and remote assets.
          It has a nationwide footprint and runs in the licensed 900Mhz frequency
          band, with no competition with voice traffic. The ReFLEX network
          was the first to carry 2Way messaging and guaranteed message delivery.
          And during the Hurricane Katrina disaster, ours was the only network
          still up and running.
