Every mobile phone does not have its own unique radio wavelength. Mobile phones operate within specific frequency bands allocated by regulatory authorities for wireless communication. These frequency bands are standardized to ensure compatibility and efficient use of the radio spectrum.
In most countries, mobile phone networks use various frequency bands for different generations of cellular technology (e.g., 2G, 3G, 4G, and 5G). These frequency bands are shared among multiple devices, allowing them to communicate with the network infrastructure and establish connections.
Within a given frequency band, multiple mobile phones can operate simultaneously, each using a different channel or frequency within that band. The network assigns these channels dynamically to individual phones, allowing them to communicate without interference.
However, it's important to note that each mobile phone does have a unique identifier called an International Mobile Equipment Identity (IMEI) number. The IMEI is a unique code assigned to each mobile device, and it helps identify the device itself rather than the radio wavelength it uses for communication.
So while mobile phones share frequency bands, they can be differentiated based on their unique IMEI numbers, but these numbers are not directly related to the radio wavelength used for communication.
