Advantages of 6.25 kHz – Channel Availability

N x d n re have more available license frequencies in the UHF band than analog, DMR, or P25. Devices such as cell phones, car fob, Bluetooth headphones and satellite TVs are a couple of examples that use radio waves. When communicating over these radio waves, each piece of technology takes up a slice in the overall electromagnetic spectrum. Within the electromagnetic spectrum, there is a limited amount of space a device can take up. For example, we have three quarters of a circle representing one version of the electromagnetic specter One cell phone takes up that entire spectrum to communicate on. If we put a two way radio and a laptop on the same spectrum to communicate at the same time with the cell phone, we are going to run into some issues. If all devices try to talk on the same sliver, spectrum, it would be impossible for anything to communicate. There are regulation set up to make sure instances like this don't happen. In the United States, the Federal Communications Commission or the FCC controls the use of the electromagnetic spectrum. For two way radios, there is a limited amount of spectrum available in any given area. From big cities to small towns, The FCC helps regulate the technology usage and allocates frequency licenses to these radios and locations. There was specific spectrum in which radios could operate on. This was the twenty five kilohertz channel spacing. Over time, radios were filling up on the twenty five kilohertz channel spacing, limiting the amount of total licenses available. In twenty thirteen, the FCC mandated that two way radios must transition from twenty five kilohertz to twelve point five kilohertz. Twelve point five kilohertz creates twice the amount of available channels compared to the twenty five kilohertz channel spacing. At the same time, the FCC also the six point two five kilohertz channel spacing available. Icom and JVC Kenwood jointly developed a two way radio protocol that can operate on six point two five kilohertz. This is called next generation digital narrowband or n x d n for short. With NXTN radios, it can operate on the same channels found on the twelve point five kilohertz channel spacing. Plus, an exclusive additional, one thousand two hundred twenty two channels found on six point two five kilohertz.
