XAP Home Automation protocol
Encyclopedia
xAP is an open protocol used for home automation and supports integration of telemetry and control devices primarily within the home. Common communications networks include RS232, RS485, Ethernet
& wireless
. xAP protocol always uses broadcast for sending the messages. All the receivers listens to the message and introspects the message header to verify whether the message is of its interest. xAP protocol has the following key advantages.
Ethernet
Ethernet is a family of computer networking technologies for local area networks commercially introduced in 1980. Standardized in IEEE 802.3, Ethernet has largely replaced competing wired LAN technologies....
& wireless
Wireless
Wireless telecommunications is the transfer of information between two or more points that are not physically connected. Distances can be short, such as a few meters for television remote control, or as far as thousands or even millions of kilometers for deep-space radio communications...
. xAP protocol always uses broadcast for sending the messages. All the receivers listens to the message and introspects the message header to verify whether the message is of its interest. xAP protocol has the following key advantages.
- It makes use of existing infrastructure wherever possible (for example it can co-exist with various physical layers like RS232 or wireless LAN)
- It can even intercommunicate between multiple networks like RS232 or wireless by just deploying a physical bridge.
- xAP does not require any central controller. All nodes can act as sender or receiver.
- xAP system provides distributed and fault tolerant architecture which allows continuous operation of systems even in the event of component failures.
