Will the future of radio be a merge of P25 and TETRA technologies?

Paul Ludvik is NSW business development manager for ComGroup Australia and is has a clear view on the future of radio. At the website of Radiocomms he said: 

"In my 19 years within the two-way radio industry I have seen many changes and developments. I have seen the transition of radios using crystals, diode matrix boards, EPROMs and DSPs for programming and frequency changes, along with the introduction of data with MDTs, GPS and telemetry within the two-way radio medium."

Recently the industry has begun to move into the digital world with TETRA and P25 protocols, adding new vibrancy to the radio industry, as the government invests in P25 technology with a focus on interoperability and high-level encryption. Within the Australian market, TETRA technologies are starting to gain real momentum thanks to the changes in the ACMA 400 MHz frequency band, allowing 25 kHz with 10 MHz or more frequency splits within 400 MHz high-density areas to cater for this technology. However, the new kid on the block is definitely DMR, which encapsulates the benefits of both P25 and the TETRA technologies......

The bridge between two-way radio, cellular and IT is becoming more and more apparent, with the onset of LTE or 4G adding to the mix, with the possibility of one day having two-way radios as an application on your smartphone. So who knows what is around the corner, but whatever the future brings, it is important that the radio industry embraces it and makes an investment in skills and training, so that we can better manage this transition and have some control of our market and destiny.
