Point-to-point (PTP) wireless networks are a type of wireless bridging system in which two devices are connected to each other using a one-to-one wireless connection. These networks are used to exchange data between the two devices by converting it from a wired cable connection into a radio frequency signal using antennas. Point-to-point wireless networks are often used to connect two devices that are located far apart from each other, or to connect devices in situations where it is not possible or practical to use a wired connection, such as where it is not possible to lay cables or where it would be too expensive to do so.
Point-to-point wireless networks typically use high gain directional antennas to transmit and receive signals in a specific direction, rather than broadcasting in all directions like omnidirectional antennas. This allows them to focus the transmission of the signal and improve the range, data speed, and reliability of the connection between the two devices.
The most common frequency band for point-to-point wireless used by brands such as Ubiquiti and Cambium is the 5 GHz unlicensed band, but can also include higher frequencies in the microwave and millimetre wave bands.
