In this current era of network innovations, Bluetooth technology is a standard concept. Thanks to its highly reliable wireless design and performance, it is one of the most popular & easiest ways of linking devices between various products that support this wireless technology such as smartphones, headphones, speakers, and fitness trackers. Bluetooth 5 is the brand’s newest breakthrough.
Bluetooth’s short history: Bluetooth was invented by Ericsson in 1994. Its name was chosen based on the King of Denmark in the 10th century named Harald Bluetooth. The Bluetooth Special Interest Group was formed in 1998 (Bluetooth SIG). As at that time, Ericsson, Nokia, IBM, Intel, and Toshiba formed the Bluetooth SIG.
Bluetooth-5 New Things
1. Simplified nomenclature
With the new version of Bluetooth, the Special Interest Group (SIG) that controls the standard chose to call it “Bluetooth 5” with no decimal point. This version still makes use of the low-energy protocol (and it has been greatly improved) but all contained in a single brand: Bluetooth 5. The Bluetooth SIG wanted to make the branding easier and more easily understood by the public.
2. Faster data transfer speed
When it comes to data transfer, Bluetooth 5 is twice quicker than v4.2. The v4.2 has a 1Mbps transfer rate, while the Bluetooth 5 transfer rate is 2Mbps.
3. Low power consumption
Bluetooth 5’s low power consumption is one of its benefits. The technology of the model relies more on the protocol for Bluetooth Low Energy (BLE), thereby reducing battery usage. Practically, if it sends more information per second rate, it also reduces the amount of time it will do so. In other words, the lower power consumption rate also means a higher transmission speed.
4. Longer communication range
The Bluetooth 5 standard makes it possible for low-energy communications to exchange data for a greater range. Much more scope: up to four times the Bluetooth 4.2 LE standard, up to nearly 800 feet or 240m. While in the real work you can do much less, it still is a huge improvement over the older Bluetooth versions. On all devices, you’re not going to get that kind of scope all the time and developers should actively choose to compromise maximum scope bandwidth. However, it is great for many devices on the Internet of Things (IoT), which often relay tiny amounts of data, but need to extend their transmission throughout a house or a large shop.
5. Increased advertising capacity
In Bluetooth communication, two main modes are used for transmission, that is Advertising and Scanning. Advertising means that the system sends advertising packets to other Bluetooth devices. All Bluetooth devices, initially start their communication in Advertizing mode. Once advertising packets are sent, target devices (scanners) pairs with it and start mutual1 communication.
In Bluetooth devices, advertising was done on three channels, while Bluetooth 5.0 makes use of 40 channels to transmit data which are all in 2.4GHz ISM band. Out of the 40 channels, 3 channels are used to transmit headers that refer to a larger payload of date in the remaining 37 channels. This feature allows for sending more payload data in the area.
6. More functionality for IoT
Bluetooth 5’s major improvements are for its Low Energy mode (BLE) only. BLE is an entirely separate standard from classic Bluetooth, first released in Bluetooth 4.0 and then enhanced in the updates v4.1 and v4.2. As of Bluetooth 4.2, BLE mode transmits much less data than the classic Bluetooth while keeping a similar range, less delay, and consuming a fraction of power.
To add to the available higher-bandwidth and longer-range links, Bluetooth 5 has introduced enhancements in low-energy service. This gives, for instance, an eight-fold increase in the capacity of transmitting data. That means eight times the number of connected devices. The Bluetooth SIG has pictured homes and businesses packed with IoT devices and has created the Bluetooth 5 standard to make them more powerful.
Bluetooth is everywhere and is rapidly growing. What started as a way of connecting dorky-looking headsets has now turned into a powerful wireless system that connects everything from speakers to heart monitors, wearables and weather stations. The latest Bluetooth update offers further enhancements but if you use the old device, it will not give you the 5.0 instant advantages. Bluetooth 5.0 is compliant with backward versions. But with other users of the upgrade edition, you can meet your needs. We gain a fourfold range of 4.2, twofold speed, and eightfold broadcast capability. Also, the Bluetooth Low Energy requirement is the best advantage for version 5. For this reason, we understand that wireless headphones can not communicate over Bluetooth Low Energy, but now version 5.0 can communicate over Bluetooth Low Energy with all audio devices.
