Although the FCC continues to defend itself against litigation that targets designated entity rules adopted for the 700 MHz D-block, wireless association CTIA removed the last legal challenge against open access provisions that pertain to the 700 MHz C-block, as it voluntarily asked the D.C. Circuit Court last Friday to dismiss CTIA’s pending lawsuit. Under rules adopted for the 700 MHz auction conducted earlier this year, the FCC implemented open access provisions that require the C-block license winners to permit subscriber usage of third-party handsets and applications as long as such devices and applications cause no harm to network operations. Asserting that the open access requirements violate the U.S. Constitution, CTIA asked the D.C. Circuit Court late last year to overturn the rules. In the year since CTIA filed its complaint, however, key players in the wireless industry, including Verizon Wireless and the Android initiative led by Google, have taken steps to open their networks to third-party devices and to promote the development of handsets and other products that can work across networks. As such, Verizon Wireless, a C-block auction winner, withdrew its legal challenge against the C-block rules at the same time that CTIA submitted its petition. Explaining CTIA’s decision finally to follow in Verizon’s footsteps, a spokesman proclaimed: “it is evident to even the most casual observer that the American consumer enjoys a handset marketplace that is vibrantly and fiercely competitive.”
