Hey, this is Ameerah Mason from UK. I am a scientist. Recently, I have researched on radio communication. PMR446 (‚??Personal Mobile Radio‚??) is called a European standard for license-free wireless communications. Radios also follow this standard as it is usually very affordable and effortless to find. They are frequently used by store staff, security guards, traffic controllers, etc. In addition, some baby monitors and toys also use the License free radios PMR 446.
