In telecommunications, a point-to-point connection refers to a communications connection between two communication endpoints or nodes.

- Point-to-point (telecommunications)

Although an experimental 40 mi microwave telecommunication link across the English Channel was demonstrated in 1931, the development of radar in World War II provided the technology for practical exploitation of microwave communication.

- Microwave transmission

Other examples of point-to-point communications links are leased lines and microwave radio relay.

- Point-to-point (telecommunications)

20th- and 21st-century technologies for long-distance communication usually involve electrical and electromagnetic technologies, such as telegraph, telephone, television and teleprinter, networks, radio, microwave transmission, optical fiber, and communications satellites.

- Telecommunications

Microwaves are widely used for point-to-point communications because their small wavelength allows conveniently-sized antennas to direct them in narrow beams, which can be pointed directly at the receiving antenna.

- Microwave transmission

Telecommunication over fixed lines is called point-to-point communication because it is between one transmitter and one receiver.
