Base band distribution systems
Telecommunications Glossary |
Usually used when the viewing areas are close together, and when tv monitors are used for viewing. the base band audio/video output from the satellite receivers is fed directly into the monitor. this form of wiring uses several twisted pair wires which can be very expensive when wiring more than 50 feet because of the need for many amplifiers and splitters. the picture quality is much sharper using a base band system, than with any other system. glossary/8

Backbone microwave system, английский
A series of directional microwave paths carrying common information to be relayed between remote points. the backbone microwave system is engineered to allow the insertion of signals, the dropping off of signals and the switching of signals along its length at designated relay points. in order to maintain the signals in the highest possible quality, the equipment used in the backbone microwave system is normally of a higher technical performance level than other microwave electronics in the network. antennas are always directional.
