'''xAP''' is an open protocol used for [[home automation]] which supports integration of telemetry and control devices primarily within the home.<ref name="ICACT-2008">{{cite conference |last1=Fioretti |first1=F. |last2=Pierleoni |first2=P. |last3=Pasqualini |first3=S. |url=https://www.researchgate.net/profile/Paola-Pierleoni/publication/4325507_On_use_of_xAP_Home_Automation_Protocol_for_networking_in_critical_environments/links/55380c310cf226723ab614d6/On-use-of-xAP-Home-Automation-Protocol-for-networking-in-critical-environments.pdf |title=On use of xAP Home Automation Protocol for networking in critical environments |conference=10th International Conference on Advanced Communication Technology (ICACT 2008) |location=Gangwon, Korea |pages=1960–1965 |date=17–20 February 2008 |access-date=12 June 2025 |doi=10.1109/ICACT.2008.4494171 |isbn=978-89-5519-136-3}}</ref> Common communications networks include [[RS-232]], [[RS-485]], [[Ethernet]] and [[wireless]]. The xAP protocol exclusively uses broadcast messages.<ref name="ICACT-2008" /> xAP receivers listen to all broadcast messages and read the message header to verify whether the message is of its interest.<ref name="ICACT-2008" /> The xAP protocol has the following key advantages:<ref name="ICACT-2008" /><br />
* It makes use of existing infrastructure wherever possible (for example it can co-exist with various physical layers like RS-232 or wireless LAN)<br />
* It can intercommunicate between multiple networks like RS-232 or wireless by just deploying a physical bridge.<br />
* xAP does not require any central controller. All nodes can act as sender or receiver.<br />
* xAP system provides distributed and fault tolerant architecture which allows continuous operation of systems even in the event of component failures.<br />
