The National Telecommunications and Information Administration (NTIA) and the Federal Communications Commission (FCC) have released reports regarding making available additional spectrum for advanced wireless services, including third-generation (3G) mobile systems. The FCC's (www.fcc.gov) report focuses on the 2500 -2690 MHz band and notes that implementation of sharing, segmentation, or relocation options would significantly affect deployment of and impose considerable costs on these system operators. NTIA's (www.ntia.doc.gov) report analyzes the potential for 3G systems to operate without causing interference in the 1710-1850 MHz radio frequency bands now used exclusively for communications by the U.S. Department of Defense and other federal government agencies.
