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.
