**Infrared Wireless Networking** uses infrared beams to send data transmissions between devices. Infrared wireless networking offers higher transmission rates, reaching 10Mbps to 16Mbps.

As expected, infrared light beams cannot penetrate objects; therefore, the signal is disrupted when something blocks the light. Infrared can be either a directed (line-of-sight) or diffuse technology. A directed infrared system provides a limited range of approximately 3 feet and typically is used for personal area networks. Diffused infrared can travel farther and is more difficult to block with a signal object. Diffused infrared wireless [[dido:public:ra:xapend:xapend.a_glossary:l:lan|LAN]] systems do not require line of sight, but usable distance is limited to room distances.

Infrared provides a secure, low-cost, convenient cable-replacement technology. It is well suited for many specific applications and environments.
