Digital bits from the processor are converted to analog signals via a Digital-to-Analog Converter (DAC), mixed with a local oscillator to reach the target radio frequency, boosted by a Power Amplifier (PA), and sent to the antenna.

Wireless communications primarily utilize the radio frequency (RF) and microwave bands of the electromagnetic spectrum, ranging from around 3 kilohertz (kHz) to 300 gigahertz (GHz). Higher frequencies offer greater bandwidth (and thus faster data rates) but suffer from shorter transmission ranges and poorer penetration through solid objects.
