spectrum

The distribution of energy arranged in order of wavelengths, it is a primary concern of next-generation wireless technology. For example, the NTIA released a report discussing the potential for 3G wireless technology to share the 1.7 GHz frequency band with existing users (which include the U.S. Department of Defense). By consensus, the NTIA concluded that frequency-sharing along this spectrum was not feasible since that particular band is used for classified command communications and contol of military satellites.
