What is RF and how is it measured?Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 gigahertz (GHz) to as low as 9 kilohertz (kHz).

What is a good RF signal?RF signal strength and wireless clients
Generally wireless client needs to be perceived at least −60 dBm or better in order to ensure the data rate of 11 Mbps and above. In fact, required signal strength varies with the modulation and channel bandwith.

Wireless transmissions are made up of radio frequency signals, or RF signals, which travel using a variety of movement behaviors (also called propagation behaviors). RF communication starts when radio waves are generated from an RF transmitter and picked up, or [heard" by a receiver at another location.
What is RF testing equipment?RF test and measurement equipment is necessary for the design, test, manufacture, and debug of radio frequency devices. Every device which uses RF, from TV and radios to Wi-Fi, cell phones, GPS, etc.

For interplanetary travel, a spacecraft can use its engines to leave Earth's orbit. It is not explicitly necessary as the initial boost given by the rocket, gravity slingshot, monopropellant/bipropellent attitude control propulsion system are enough for the exploration of the solar system (see New Horizons).
How do probes communicate with Earth?Operators at the Deep Space Network take commands, break them into digital bits, precisely aim these big antennas at the spacecraft, and send the commands to the spacecraft using radio waves. The antennas of NASA's Deep Space Network are the indispensable link to robotic explorers venturing beyond Earth.wafer testing
