Switch - A switch is a multi-port network bridge that processes and forwards data at the data link layer (layer 2) of the OSI model. Some switches have additional features, including the ability to route packets. These switches are commonly known as layer-3 or multilayer switches.
Router - A router is a networking device that forwards data packets between computer networks, commonly specialized hardware. This creates an overlay internetwork, as a router is connected to two or more data lines from different networks.
Infrared (IR) - Infrared (IR) is a wireless mobile technology used for device communication over short ranges.
Radio Frequency - RF is any frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. Many wireless technologies are based on RF field propagation.
Microwave - A series of microwave repeaters, spaced up to 50 miles (80 kilometers) apart, which relay messages over long distances using highly directional microwave
