If you are comparing the unit price of two radios, you need to check that they really are comparable.
A TETRA radio unit on its own is worthless if you don’t have all the elements that make it a working unit. So, instead of simply considering the radio’s price, you need to see the whole package.
The most important thing is to check the radio offered actually works in your frequency and has the correct TETRA Encryption Algorithm (TEA) activated – this will be either TEA1, TEA2 or TEA3. Because without the correct TEA in both the radio and base station, your radio can never connect to your network. You also need the proper software to operate it, a battery and a charger to get it powered and not forgetting an antenna.
Your radio must be configurable to fit your specific duties. Check that the functions you need, like GPS, are actually included. If the offered price includes only the radio unit, it may seem a bargain, but you will need to buy all the other items separately. The result could be a much higher final price than a “plug & play” radio package, with all the necessary items included in the price.
Don’t fall into the trap of a low price if it doesn’t give you what you need –always check that it gives value for money.
