Wireless alternative

Loea Corp., a subsidiary of San Diego-based Trex Enterprises Corp., has released a laser-based, gigabit-speed transceiver that can transmit 1.25 gigabits per second, making it a good alternative, or backup, to fiber-optic links in campus environments.

Using the 71 to 76 gigahertz portion of the spectrum, the wireless technology uses pencil-size, low-power laser beams of about 30 milliwatts to carry information, even through fog or rain. The technology is available on the General Services Administration schedule through networking integrator Marshall Communications Corp. of Washington. Early adopters include the University of Hawaii, which uses a 2.7 mile link to join two campuses, and the Navy's Pacific Missile Range Facility in Hawaii.
