![]() ![]() Today, you can find smart home gateway that supports multiple protocols including WiFi, ZigBee and Z-Wave. Devices include door/window sensors, door locks, PIR motion detectors, Smoke/heat detectors. ZigBee products operate in the 2.4GHz wireless signal, the ZigBee Alliance has many different standard for specific technologies, for example ZigBee IP, ZigBee RF4CE, and ZigBee PRO, and recently has combined all application profiles into a single solution called ZigBee 3.0 on the other hand, the Z-Wave uses the 900 MHz spectrum to communicate. Although both of them are quite similar, read this article you can know difference between Z-Wave and ZigBee. 1# Z-Wave and ZigBeeīoth Z-Wave and ZigBee are widely used in Smart Home products, they own low-data, short distance transmission characteristic, and their mesh networking capability can extend the transmission distance if necessary. Today, these IoT & SmartHome protocols own specific pros and cons, they offer different data transmission speeds, range of transmission, power consumption, and level of security. Having the solid understanding of network, data security and privacy concerns is very important to security professionals. Against this backdrop, knowledge on IoT and the various communication technologies/protocols associated with it becomes key." said William Pao. "With IoT becoming so prevalent, it is difficult not to count security as part of the whole IoT revolution. ![]() ![]() In this article, William Pao is pleased to introduce the different protocols that widely used in today's IoT and Smart Home industry, these protocols include familiar Z-Wave, ZigBee, WiFi and less popular EnOcean and Sigfox, Neul, and LoRaWAN. William Pao is the senior consultant from A & S International magazine, he has expertise in IoT and Smart Home industry. Almost 6.4 billion IoT products will be in use worldwide in 2016, up 30 percent from 2015, and will reach 20.8 billion by 2020. Based on recent market research published by Gartner, the Internet of Things (IoT) has already become popular market that attracts many users and suppliers.
