Linearity is the property of a mathematical relationship or function which means that it can be graphically represented as a straight line.

Examples are the relationship of voltage and current across a resistor (Ohm's law), or the mass and weight of an object.

Proportionality implies linearity, but linearity does not imply proportionality.

Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 MHz and 3 GHz, also known as the decimetre band as the wavelengths range from one meter to one decimetre.

Radio waves with frequencies above the UHF band fall into the SHF (super-high frequency) or microwave frequency range.

Lower frequency signals fall into the VHF (very high frequency) or lower bands.

UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception.

They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications.

Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects.

The tags contain electronically stored information.

Passive tags collect energy from a nearby RFID reader's interrogating radio waves.

Active tags have a local power source such as a battery and may operate at hundreds of meters from the RFID reader.

Unlike a barcode, the tag need not be within the line of sight of the reader, so it may be embedded in the tracked object.

RFID is one method for Automatic Identification and Data Capture (AIDC).

Optoelectronics is the study and application of electronic devices and systems that source, detect and control light, usually considered a sub-field of photonics.

In this context, light often includes invisible forms of radiation such as gamma rays, X-rays, ultraviolet and infrared, in addition to visible light.

Optoelectronic devices are electrical-to-optical or optical-to-electrical transducers, or instruments that use such devices in their operation.

Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects.

It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain.

A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the object(s).

Radio waves (pulsed or continuous) from the transmitter reflect off the object and return to the receiver, giving information about the object's location and speed.
