The wireless devices are causing interference to the local Japanese emergency services, cellular-phone services and other local businesses, such as trucking companies, that all pay to use frequencies,” said Gunnery Sgt. Sonia F. Powell, Marine Corps Bases Japan spectrum manager for G-6 Communications.
According to MCBJ/III Marine Expeditionary Force Order 2400.1, family radio-service devices, commonly known as “walkie talkies,” baby monitors, wireless television cameras and cordless phones, unless they operate in the 2.4 gigahertz frequency range, are prohibited. Most cordless phones transmit at 900 megahertz, which causes interference.Learn more from Defense Video & Imagery Distribution System.
