What is IDU in telecom?

, , Leave a comment

IDU stands for “indoor unit” and in the telecommunications industry, it refers to the device that is connected to the computer router or television to accept the signal from a satellite for example. The signal may be for satellite television or part of an internet service provided by a telecommunications company, internet service provider, or satellite TV company. The basic function of the IDU is to receive and or decode signals that it is able to receive. With this kind of function, IDUs are also referred to as signal decoders and readers. In today’s world of evolving technology, many television and internet services are provided by telecommunications providers through the use of satellites. The signals that come from these satellites are transmitted to offices and households through special decoders like the indoor unit or IDU. Without this particular device, the satellite television or digital internet service signal may not be accepted and decoded properly for viewing purposes. Signals are then rendered that useless if there is no IDU attached to a router or television set.

Along with ongoing enhancements in satellite TV and internet technology, some companies have also made enhancements to their indoor units or IDUs. Some of these units not only receive and decode satellite signals but also provide added features like pay-per-view options. There are also some who configured IDUs to receive transmissions and signals from other satellites which is typically illegal in nature. Despite this concern though, the use of satellite-based television and internet service is growing more and more popular in the US and in many industrialized and developing countries around the world.

Many people appreciate having IDUs because of the ease in operations and the hassle-free installation. It is typically connected near the TV or computer router and does not take too much space. Operating it is also made simple and easy making navigation of the internet and TV channels smooth and hassle-free. With IDUs installed in homes and offices, these devices are also equipped with internal testing functionality to ensure that they are functioning well.
