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
There is no such thing as “transmitting digital”. All RF signals are analog. Digital vs. analog is purely in how the receiver interprets the analog signal.
By “RF” I think you mean AM and FM radio, and related technologies like VHF voice. These are analog signals that are interpreted that way by the receiving equipment. WiFi and Bluetooth are also analog transmissions, albeit at a different frequency than AM, FM, or VHF. The receivers interpret it as a digital signal.
The range doesn’t really relate to analog vs. digital, satellite Internet is digital and it goes thousands of miles. Range is a function of frequency (lower goes farther) and power (higher power goes farther).
