Wireless Communication Short-range wireless communication. Line of sight communication. Data transmission bidirectionally. Computer infrared network adapters both transmit and receive data through ports on a device.
Omni directional Single base station within line of sight of all other stations on LAN Station typically mounted on ceiling Base station acts as a multiport repeater Ceiling transmitter broadcasts signal received by IR transceivers IR transceivers transmit with directional beam aimed at ceiling base unit
Infrared Data Association communication protocol
Infrared Data Association IrDA via USB IrDA with mobile phone
Establishing an Infrared Network Need infrared port for the connectivity. Port will receive and transmit data. Install the infrared adapters. Work in the direct line of sight direction. The speed of connection is very slow.
