The remainder with this document will address each communication technology on the basis of the criteria that are above.
KNX
KNX is definitely an international standard of communication typically set up in wired pair that is twisted. KNX was developed in 1990 and was made being a very protocol that is robust be utilized in industrial automation applications. The protocols dependability cannot be questioned since it implements many OSI communication layers and it is quite complex. KNX is also controlled by the KNX relationship and any ongoing business often spends tens of thousands of dirhams on their workers to go through trained in order to comprehend the inner workings regarding the system. KNX is a complex protocol by nature, and was designed well before the \"smart home\" concept came to be, therefore the hardware that has the ability to offer the complexity of KNX is costly not only to engineer, but also to manufacture and so the hopes for this technology to be cheaper than its present options is futile.
KNX has and it is a choice that is popular accommodations since 2006 and has been implemented in a lot of developments like the Shangri-la in Dubai, Rotana Hotels within the Marina, Fairmont, Movenpick to call a couple of. KNX is also being specified by numerous real estate professionals for major developments within the Abu Dhabi Reem Island and Yas Island.

Zigbee
ZigBee is an open network that is wireless protocol based on the IEEE specification IEEE 802.15.4, which allows the Controller to talk to its Modules via Radio Frequency. The typical is just a development of the ZigBee Alliance, that has been started within the final end of 2002. It is an industry alliance in excess of 230 enterprises who occupy the development that is worldwide of technology. The first ZigBee products came available on the market at first of 2005. Because Zigbee standardises only the reduced protocol levels (radio layer), the manufacturers that are different defined their own greater computer software layers. As a result ZigBee devices of different manufacturers are not suitable for one another.
Reliability of Correspondence: Yes. A wireless mesh network is created and ensures multiple course routing to every module which translates to long reach, and high dependability in case there is interference if not in case there is in-path unit failure.
Security of Communication: No. Zigbee makes use of weak hashing algorithms and has been investigated become penetrable. Penetration is not effortless but computer software tools such as for instance \"Killerbee\" exist and that can enable anyone with small Linux and experience that is scripting hack into a preexisting Zigbee network.
Cost: No
Features and Capabilities: Yes
Investment Protection: Yes
Interoperability: No
