WT4 Millimeter Waveguide System: The WT4/WT4A Millimeter- Wave Transmission System
01 December 1977
The WT4/WT4A c o m m u n i c a t i o n s y s t e m is d e s i g n e d to p r o v i d e longdistance communication service at a lower per circuit cost when fully loaded and with an order of magnitude higher reliability then has been achieved previously in right-of-way systems. In the WT4 version, capacity is almost two times that of any existing system, and in the WT4A version, capacity is twice that of WT4. Digital signal transmission is used which can accommodate any mix of voice, high-speed data, TV, and PICTUREPHONE® service. The system can be installed readily on any terrain and any right-of-way. Methods and procedures have been developed for easy low-cost maintenance.
