Radios have been featured a lot in the past but off late people have started moving towards more advanced technologies such as the mobile phones and the internet. Even then these radios are being used in the defence and safety departments of various countries. The technological advancements have also been made in the radio technologies and people have started to move from the DMR radio to the TETRA radio which is the latest in the technology as of now. These radios are further advancements of the trunked radio technology that has been used for the emergency services and at airports and metro train stations throughout the world.
Trunked radio offers you with a solution of minimizing the number of lines that would be required if many people would have wanted to connect at the same time. TETRA radio further advances the same technology and offers the following upgrades:
- Lowers the cost of infrastructure which would have been more in case these radios were not used.
- It uses small frequency transmitters and hence the depth of penetration of the signals is greater and hence a larger area is covered in the same amount of signals for which other radios would have required great signal strength.
- Works well in low signal areas wherein other radios would require installation of repeaters. Hence acts as a cost saver.
- Transfers and receives data at a comparatively very fast speed as compared to other normal radios.
- Can receive and transmit encrypted signals at both the user ends.
