April 4, 2002--Canon's Canobeam DT-55, built for fiberless transmission of Gigabit Ethernet, features an Auto-Tracking System and constant footprint function. It has a range of 100 to 1,000 m.
With the auto-tracking function, the Canobeam DT-55 maintains alignment between units with maximum reliability, even under conditions in which buildings or other platforms sway due to altitude or wind conditions. With constant footprint, the DT-55 adjusts the beam according to the distance it must travel, maintaining beam focus and signal strength fully over its 100-m to 1,000-m range. No FCC frequency allocation is required.
