Bluetooth technology is one of the world's best known brands and one of the most ubiquitous wireless communications technologies on the planet. It's been in existence since 2000 and has found its way into billions and billions of devices. Last year alone, over three billion Bluetooth devices were shipped by manufacturers.
Introduction:Bluetooth Mesh Technology
Bluetooth mesh networking is the latest chapter in this incredible technology story and 150 companies, all members of the Bluetooth SIG, have helped create it.
Flavors and Features
- Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) was the first flavor of Bluetooth to be released. It was intended to act as a cable replacement technology and soon came to dominate wireless audio products and be the enabler for new computer peripherals, such as wireless mice and keyboards.
- Bluetooth Low Energy (LE) was the next truly distinct Bluetooth technology to appear. It was optimized to use as little energy as possible with devices that incorporate it and able to operate and communicate wirelessly, powered by only a coin-sized battery, which could often last for many years.
- It's been very widely adopted. It's hard to find a smartphone or tablet that doesn't support Bluetooth LE. Health, sports and fitness devices, like activity trackers, rely on Bluetooth LE technology. So do wearables, like smart watches. The impact of this Bluetooth flavor has been impressive and widespread.
Motivation for Mesh Networking
Bluetooth mesh networking was created because mesh topologies offer the best way to meet various, increasingly common communications requirements, typified by applications such as building automation and sensor networks. Those requirements include:
- Coverage of very large areas
- "Just works interoperability"
- The ability to monitor and control large numbers of devices
- Optimized, low energy consumption
- Efficient use of radio resources, leading to scalability
- Compatibility with currently available smartphone, tablet and personal computer products
- Industry-standard, government-grade security
Why build with Bluetooth ?
Bluetooth wireless connectivity is easy to implement and can help you achieve mass market adoption. Backed by a proven record of market creation, technology innovation and global leadership, Bluetooth sets the standard for wireless connectivity.
Origin of the Bluetooth Name
For how innovative the technology, the name doesn’t sound techie. It’s not an acronym and doesn’t stand for anything. So what does it mean?
Surprisingly, the name dates back more than a millennia to King Harald “Bluetooth” Gormsson who was well known for two things:
- Uniting Denmark and Norway in 958.
- His dead tooth, which was a dark blue/grey color, and earned him the nickname Bluetooth.
2.Code for Collaboration
- In 1996, three industry leaders, Intel, Ericsson, and Nokia, met to plan the standardization of this short-range radio technology to support connectivity and collaboration between different products and industries.
- During this meeting, Jim Kardash from Intel suggested Bluetooth as a temporary code name. Kardash was later quoted as saying, "King Harald Bluetooth...was famous for uniting Scandinavia just as we intended to unite the PC and cellular industries with a short-range wireless link."
