From high-tech lasers to old school wire, Marines test both ends of communications spectrum
By: Todd South  
Marines recently hit both ends of the communications spectrum with Jarheads in Okinawa using infrared lasers to send large data files without using radio frequencies that easily can be jammed to stateside Marines shooting old-school high frequency comms from Wisconsin to Miramar, California.
Marines with 7th Communications Battalion, III Marine Expeditionary Force at Camp Hansen, Okinawa, tested the “free space optics†system under development by the U.S. Naval Research Laboratory. They transferred data at higher rates by using an infrared laser for ground-to-ground comms, according to a III MEF release.
