They all using frequencies to transmit signals so how RF is transmitting analog and Bluetooth and Wifi digital signals ? And why transmitting analog signals over long distances is easier than bluetooth ?
In: Technology
RF just stands for Radio Frequency. Bluetooth is a protocol that was invented for low power short range communication. It doesn’t work for longer ranges because it wasn’t invented to do so. WiFi is another protocol that was invented for longer range. They both are just transmitting radio, but Bluetooth was made for lower power. It like the difference between a keychain light and a large flashlight. They both do the same thing, but one was meant to be low power for shorter distances.
