Modern telecommunication is making our planet shrink by reducing the effect of geographic distance between any two cities in the world. Telecommunication, as we see it today, is enabled by a combination of few backbone technologies that can efficiently carry voice and data related information with great speeds and reduced distortion. We look at three path-breaking technologies that rest at the heart of any global telecommunication network today.
The most cost effective way of transmitting information over long distances is the wireless way. Specific radio and microwave frequencies are used to carry information. Line-of-sight alignment is required for two wireless transceivers to communicate with each other. For this purpose, we require tall telecom towers that keep the transmission devices high above buildings, hills and other structures situated in the vicinity.
Telecom towers are constructed in a variety of ways depending on the exact requirement. The most common design is the steel latticed structure made using L-section steel elements. Tubular section telecom tower is another popularly used design. For longer range microwave link, we also have dedicated Reinforced concrete buildings holding the telecom devices with manned control centers within it.
Fiber Optic Link around Globe (FLAG)
One of the fastest modes, with highest immunity to noise is the use of Fiber Optic cables. Although expensive, FLAG links span across continents with long stretches passing even undersea through deep ocean beds. These cables have very high bandwidth throughput. Most of Internet traffic from around the world is routed through FLAG undersea cables. Signals travelling through these cables travel in the form of light pulses, which is the fasted medium ever known. Light pulses are also immune to electromagnetic interference and are virtually noise-free.
Earth Stations
Satellite communications is one of the popularly used global means of communication. The arrangement involves base stations, or earth station with large parabolic antennae that beam and receive signals with other stations through geo-synchronous communication satellites. Communication through earth stations and satellites involves thorough knowledge of behavior of the earth's atmosphere and the way high frequency radio beams travel through it.
A telecom service provider with global presence will need to use a fine combination of the technologies mentioned above for transmission of data.
Telecom turnkey solutions help service providers set up infrastructure for each of these modes of communication on a specialized project basis. The overall construction and design of these installations is an area of expertise of turnkey telecom solution providers.
