PMR

PMR (Private Mobile Radio)

PMR is an abbreviation for Private Mobile Radio or also known as Personal Mobile Radio. It is a system of license-free, short-range radio frequencies that enable personal communication over short distances. This system is widely used for personal and business communication, especially where quick and reliable wireless communication is needed without the requirement of acquiring a license.

Key Features of PMR:

License-free operation: It operates on license-free frequencies, meaning users do not need to obtain special licenses to use these devices.

Short distance: PMR devices are designed for communication over short distances, which is ideal for personal communication within a group or for business use in confined spaces.

Easy usability: PMR radios, similar to walkie-talkies, are typically easy to operate, making them user-friendly without the need for complex settings.

Wide usability: PMR finds applications in various situations, such as outdoor activities, organized events, industrial and business environments, and anywhere reliable and fast wireless communication over short distances is needed.

PMR is a popular choice for those who need a simple and efficient way of wireless communication without the complexity associated with licensed frequencies.

PMR radio frequencies are typically assigned in predefined channels. For simplified usage, they are often referred to by numbers corresponding to these channels.

Here is an example of channel numbering for PMR radios:

1. 446.00625 MHz

2. 446.01875 MHz

3. 446.03125 MHz

4. 446.04375 MHz

5. 446.05625 MHz

6. 446.06875 MHz

7. 446.08125 MHz

8. 446.09375 MHz

9. 446.10625 MHz

10. 446.11875 MHz

11. 446.13125 MHz

12. 446.14375 MHz

13. 446.15625 MHz

14. 446.16875 MHz

15. 446.18125 MHz

16. 446.19375 MHz

These frequency ranges are typical for the PMR446 standard, which is often used in Europe for license-free short-range communication.
