A CB radio, because it has much higher power, can transmit about 5 miles 8 kilometers using a 5-watt transmitter. Cell phones operate within cells , and they can switch cells as they move around. Cells give mobile phones incredible range. Someone using a cell phone can drive hundreds of miles and maintain a conversation the entire time because of the cellular approach.

What does a base station do? What are 2G and 3G networks? Mobile phones work by sending and receiving low power radio signals. The signals are sent to and received from antennas that are attached to radio transmitters and receivers, commonly referred to as mobile phone base stations.
What happens when I make a call from my mobile phone? The first step in the process is for the phone to check that there is coverage in the area that the call is made. It can be used to replace cables between computers, tablets, speakers, mobile telephones between one another or with printers, scanners, keyboards, mice, game pads, portable phones, personal assistants, hands-free microphone or earphone systems, radios, digital cameras, bar code readers and interactive advertising booths.
With some mobile phone models, it is already being used for paying and validation of transport tickets, and could eventually replace credit cards see here opens in a new window an example of NFC application.
It allows automatic detection with reading distances greater than for NFC. LoRa is a long-range network technology which supports low bandwidth communication between connected objects. The great advantage of LoRa, compared with a conventional cellular network, is the autonomy of receivers as well as the cost of use. The LoRa network has been designed to minimize energy consumption.
