All You Need to Know About the Digital Radios NXDN Vs. DMR

There is a crossroads when you consider migrating to digital radios. All radios worked together for many years, and it didn't matter what manufacturers you choose. For instance, if you had some Motorola radios, but Kenwood has some latest hot product, it wasn't a problem earlier, but it doesn't work anymore with Hytera digital radios. Ideally, FCC is an attempt to hunt the room for more radio users. It indicates that license free radios PMR 446 would use less bandwidth to transmit through. Manufacturers have made their equipment capable of doing this, and frequently users bought replacement radios to be compliant. Hence, they created more slots available in between. You can think of it as users suddenly standing shoulders to shoulders turning sideways. 

Furthermore, FCC is known to be a stepping stone on the way to the final destination of 6.25 Hz. The major problem here is that you can't transmit voice through the narrow bandwidth, but you can transfer data. It is where digital radios come into the picture. Two critical technologies created are time division multiple access that is TDMA, and frequency division multiple access that is FDMA. The primary part about these technologies is that they are compliant with the FCC. But you should know that these technologies are incompatible without each other.

Either of technology works if you want to connect with few individuals. DP4401e radio featuring TDMA is a clear-cut winner if you have multiple groups to communicate. It would be best if you had numerous frequencies to provide capacity even though FDMA accomplishes the same goal. In some cases, you also have to increase your infrastructure costs and put restrictions on multiple group communication. TDMA technology makes it realistic if you want to incorporate individual calls. Under FDMA, no transmission can go through if there is a transmission on the frequency. You can effectively utilize personal calls, group calls, and all calls with a single frequency under TDMA. While this can be quite confusing, but professionals can help you navigate the nuances of various technologies and choose a plan that meets your digital migration platform.
