Bluetooth mesh in lighting: What comes next?
Mesh networking with Bluetooth has a bright future. By taking advantage of existing lighting systems you open the door to huge added value possibilities, both for your business and its customers.
While mesh networking is nothing new, it is only now starting to be adopted in industrial and commercial environments. Bluetooth Mesh offers a low power mesh network with the potential to deliver many and varied added value services.
Mesh networks explained
Some people in the industry view mesh networking as the next ‘shiny object’, nothing more than another excuse to raise prices. But mesh does deliver significant benefits over star or peer-to-peer networks and looks set to make a real impact on the industrial IoT and in the smart home in the years to come.
The reason is simple: mesh networks solve a specific problem. A conventional wireless router offers limited coverage if you can’t hardwire additional access points to it, which drives up complexity and expense in large spaces such an office building. On the other hand, mesh networks bring wireless connectivity to such a space far more simply than ever before.
Renesas:Outdoor Sensor for Automatic Home or Building HVAC System
The outdoor sensor unit(s) for automatic home or building HVAC systems provide outdoor data from one or multiple bearings (North, East, West, South) to a master actuator. This can be one or all of the following data:
- Outdoor air quality (OAQ according to the Environmental Protection Agency)
- Temperature and relative humidity (degrees, percentage)
- Light/Sun (lux)
- Barometric pressure (mbar)
蓝牙5和Mesh技术为物联网市场带来强而有力的加值作用
物联网发展到如今,无线技术纷繁复杂,往往会出现在同一区域的不同设备上,这些无线通信设备之间会出现相互干扰的现象。然而,蓝牙5标准可以减少和其他无线通信技术之间存在的干扰,帮助设备在复杂的物联网环境中与其他无线设备并存。
蓝牙5是由蓝牙技术联盟在2016年提出的蓝牙技术标准,蓝牙5在蓝牙4.2核心规范上大幅提升效能,包括「2倍的传输速度」「4倍的传输距离」「8倍的广播数据传输量」等新优势,强化了在物联网方面的新特性,重点提高物联网的功能。
