TETRA Technology Advantages & Benefits
So why is the world of PMR communications moving from analogue to digital? The way to answer this question is to compare the relative advantages and disadvantages of analogue and digital in the important performance areas of: Voice Quality, RF Coverage, Non-Voice Services, Security and Cost.
Nowadays, practically everything electronic uses digital technology and wireless communications are no exception. Even though analogue FM PMR communications will remain a viable option for several years, the move towards digital PMR started over a decade ago and the trend is still rapidly increasing and many end users are using the new DMR technology for their communications.
The core technologies used in the TETRA standard provide a number of inherent advantages and benefits as well. These core technologies are:
