The Bluetooth Special Interest Group (SIG) first unveiled the tentative specifications that the Bluetooth 5 could come with. However, now, the new specifications have been finalised by the industry group and are also set to be featured in new devices. The SIG says, devices with the new Bluetooth 5, can be expected to be in the market in “two to six months”.
According to the official website for Bluetooth 5, the new and updated feature will come with twice the bandwidth, four times the range, and eight times the broadcasting message capacity of Bluetooth 4.2, when used with low energy devices. The maximum speed is now 2Mbps, up from 1Mbps. However, according to the needs of the device, the bandwidth can be decreased in order to allow for four times longer range while maintaining similar low power requirements.
“Bluetooth is revolutionising how people experience the IoT. Bluetooth 5 continues to drive this revolution by delivering reliable IoT connections and mobilising the adoption of beacons, which in turn will decrease connection barriers and enable a seamless IoT experience,” said Mark Powell, Executive Director of Bluetooth SIG.
Additionally, Bluetooth 5 supports larger data packets than its predecessors. It works with 255-octet packages. In simpler words, Bluetooth 5 makes more efficient use of the crowded 2.4GHz band, with less broadcast time required to complete tasks. As you’d expect, the Bluetooth 5 specifications are backwards compatible with its predecessors. For low energy devices this means down to Bluetooth 4.0 LE, and for all the others the interoperability goes back to the specification of the Bluetooth 1.1.
Further, the enhancements in Bluetooth 5 bring better functionality to Internet-of-Things (IoT) devices. Bluetooth 5 aims at delivering reliable IoT connections and mobilising the adoption of beacons, which in turn will decrease connection barriers and enable a seamless IoT experience. Also, for developers, Bluetooth 5 offers the ease to build IoT solutions based on feature need, like range, speed and security, which can be adjusted for a variety of environments and end products. The increased speed of Bluetooth 5 lays the groundwork for the next generation of Bluetooth audio, and the increased range will deliver reliable IoT connections that make full-home, building, and outdoor use cases a reality.
