PLANNING THE TELEPHONE HIGHWAYS
The millimeter waveguide system now under development at Bell Laboratories is expected to go in service in 1980 as the next stage of evolution beyond coaxial cable. It has a capacity of 1/4 million voice channels and will become the backbone of the long-distance network. Waveguide resembles a rugged steel pipe. Virtually all coaxial cable routes are on private right-of-way. Land use and environmental impact might be minimized if waveguide were located on freeway right-of-way where the routing is coincident and where the right-of-way is adequate to permit economic construction without disruption to highway usage or safety. A joint study is proposed to evaluate the feasibility of this alternative.
