Zigbee Vs Wifi Lights4/21/2021
Todays lighting components must be able to talk to one another, meaning they must use the same communication protocols to trigger specific actions, such as synchronizing and dimming light fixtures.Popular wireless protocols include Infrared, Bluetooth, Wi-Fi, Zigbee, Thread, Z-Wave and KNX.
Zigbee Vs Wifi Lights Trial Lighting ApplicationsThis article identifies standard features as well as dissimilarities among three popular wireless protocols Bluetooth,Wi-Fi and Zigbee and outlines best industrial lighting applications for each technology. Wi-Fi first gained popularity for media streaming gaming, browsing the web and other data-heavy activities because of its high bandwidth capability. Wi-Fi uses radio frequency to transmit data through the air. The communication protocol is stable and cost-effective, yet traditionally many designers avoided the technology in industrial applications because of its high power requirements. ![]() Because of the limitations on the number of network-connected devices, the technology is more suitable for small commercial lighting applications. Its maximum speed of 250 kbps at 2.4 GHz makes it slower than other popular wireless standards. However, ZigBee shines in comparison to the other wireless protocols in power consumption efficiency. Zigbee was designed to transmit small packets of data at relatively infrequent intervals, making it easy to connect battery-operated devices such as LED lighting. Mesh-networked devices use each other to transmit signals; often referred to as many-to-many (m:m) communication. Mesh networking topology strengthens connectivity and increases network scalability, opening the pathway for designers to incorporate the technology in increasingly sophisticated industrial lighting applications. Zigbee aims to be the global standard for all Internet of Things (IoT) solutions. According to the Zigbee Alliance, the IoT market is expected to grow from 180 million in 2014 to more than 1 trillion by the year 2020. It is no surprise, therefore that manufacturers, like GRE Alpha Electronics, are jumping at the chance to get in on this technology. The company specializes in the design of solid-state lighting power supplies and lighting control accessories and is a trailblazer in the design of Zigbee-certified devices. Its SLD-SMARTDIM wireless dimming module, for example, is Zigbee-enabled and compatible with a wide variety of smart switches and controls. The module delivers flicker-free 0-100 dimming and a fast response time for easy control of constant voltage LED fixtures. The newest version, Bluetooth Low Energy (LE), uses very little power compared to the original variety. The addition of mesh networking support in the summer of 2017, opened the floodgates to sophisticated industrial lighting applications. Like Zigbee, the technology supports complex many-to-many device communication, and networks can be designed to cover large physical areas. The technology is also interoperable across products from different vendors and is secure, scalable and upgradeable, making it a key player in the IoT market and especially suitable for large-scale industrial lighting automation applications. GRE Alpha recently partnered with the EnOcean Alliance to further develop its wireless offerings to Bluetooth LE-enabled devices and other wireless applications.
