The Coalition for 4G in America submitted a letter and paper supporting the promotion of interoperability across the entire 700 MHz Band to ensure the development of a multiband commercial and public safety device ecosystem. The 4G Coalition supports the establishment of a band class for all paired bands in the Lower 700 MHz block and another band class for the Upper 700 MHz block. The 4G Coalition is made up of RTG, RCA, Sprint Nextel, T-Mobile, MetroPCS, Cellular South, Access Spectrum and Xanadoo.
