On ZigBee technology and application smart home Internet of Things connection helper

Wireless networks come in a wide variety of specifications, such as the most common Wi-Fi, which is a high-speed transmission standard that enables wireless local area networks (WLANs) to connect mobile devices wirelessly. As for smart homes, smart buildings, wireless sensing networks, etc., most of them do not use Wi-Fi, but use ZigBee technology for transmission. ZigBee has entered the home control and automation market with short distance, low power consumption and low cost. It has also been adopted and imported by many manufacturers. Then let's dive deeper into the technology and applications of ZigBee...

Achieve a wide range of applications for IoT applications

ZigBee is a short-range, low-power wireless communication protocol standard . It was first proposed by Honeywell Corporation of the United States. It was conceived and developed in 1998, and launched a self-networking (Self Organization) wireless peer-to-peer (ad-hoc). The network standard, the ZigBee Alliance business organization established by it, was incorporated into the IEEE 802.15.4 standard specification in 2001 by the Institute of Electrical and Electronics Engineers (IEEE), and officially released ZigBee 1.0 (also known as ZigBee 2004) in 2005. Since the industrial specification, ZigBee has gradually become one of the low-speed short-range wireless communication technologies common to all industries.

Intelligent Home Internet of Things Connection: On ZigBee Technology and Applications

ZigBee has evolved to version 1.2, extending application standards to home entertainment and control, wireless sensing network (WSN), industrial control, embedded sensing, medical data collection, smoke screens and tamper warnings, and architecture In the field of automation, and there are various application class standards (Profile Class), when the Internet of Things (IoT) era is coming, ZigBee Alliance launched version 2.0, which focuses on smart energy specifications.

In addition, the 3.0 version will be officially launched in 2015, which will unify the different ZigBee standards of various devices in the past, so that applications can be highly interoperable and secure, while maintaining the advantages of low power consumption, providing the most suitable industry standard for the Internet of Things. .

Brief description of ZigBee technology, low cost, short distance, low cost, multiple network topologies

ZigBee is based on WPAN (Wireless Personal Area Network) applications, and its underlying IEEE Media Access Control Layer (MAC) and Physical Layer (Physical Layer; PHY) are adopted in the IEEE 802.15.4 standard. .

The main features are short distance (within 50 meters), low speed (250Kbps), low power consumption, low cost, low complexity, fast installation, reliability and security, and can support a large number of network nodes (up to 65,000). And support a variety of network topologies (such as Star Star, Cluster Tree Cluster, Mesh mesh).
