Optical & broadcast communication equipment · Hangzhou, China

Community and rural coverage

Cost-effective transmission for residential districts, villages and remote areas, where the run to the antenna is long and coverage has to hold over distance.

Overview

Broadcast television

Coverage projects are decided by geography. The headend is the simple part; what determines whether the service works is the path from the transmit antenna to the receiver, and the terrain in between.

That is why we ask for a coverage map and the approximate radius before quoting. The same headend can need a different output level, a different antenna or an additional site depending on the answer.

How the system works

What goes in the rack

These are the units this kind of project normally needs. The exact mix depends on the scale — tell us the site and we will confirm it.

Design

What decides the design

Four things that change the specification more than the equipment list does.

  • Terrain and radius Send the coverage map or an approximate radius. Obstructions matter more than distance, and they decide the output level.
  • Output level and licensing Transmit power is set by local regulation. Tell us the country and we will confirm the permissible configuration.
  • Power availability Remote sites often have unstable or limited power. The equipment range covers both AC and DC arrangements.
  • Weather and housing Outside-plant equipment has to survive the local climate. Specify the environment and we will confirm the enclosure rating.

Typical configurations
