Wireless communication between electronics devices can be done using these modules. Operating in the unregulated spectrum these low power transceivers are an ideal way to connect microcontrollers and computers together using common WiFi, Bluetooth, Xbee and other protocols.
Without using wires there is a lot of flexibility in extending systems around a local area where cabling is unsightly or difficult. Communicating with mobile vehicles also demands no wires lest there be a big tangle!
Communication can be done using serial, TCP/IP, UDP for maximum flexibility in data transmission. Connect remote sensors to a computer across your garden or across the world. Stream data from a remotely operated vehicle.
