Given the impressive efficiency of BLE, one may think that it has completely supplanted the classic version. A small 1,000 mAh coin cell battery can keep it going for up to two years, according to the blog. “The data is sent in small (20 bytes) packages, but the range can be even more than 100 meters (330 feet) and the minimum latency between unconnected state to data transfer can be counted in a handful of milliseconds, while in BT Classic it’s about 100 ms.”Īs a result, all it takes to power basic BLE devices is a very small battery. That’s because where BC consumes a full watt, BLE only consumer 0.1-0.5 watts of energy. The amount of energy saved as a result is quite impressive.Īccording to The Droids on Droids, an Android blog, it can achieve “as much as 100x lower power consumption” than its classic counterpart. The way BLE achieves a reduction in energy consumption is by staying in sleep mode until roused by activation through a connection. The original form that some may call Bluetooth classic was reinvented more than once, most significantly in 2011 when it released version 4.0 AKA Bluetooth Low Energy (BLE), which leads some to refer to the other version as Bluetooth Classic (BC). Data is split into packets and exchanged through one of 79 designated Bluetooth channels (each of which have 1 MHz in bandwidth).”Īs with all technology, Bluetooth did not remain static. “Bluetooth operates in the 2400-2483.5 MHz range within the ISM 2.4 GHz frequency band. The distance between Bluetooth devices is often much smaller, as in the case of using a wireless keyboard within a couple of feet of your computer or a wireless headset near your phone. That’s why the signal won’t usually extend beyond 30 feet. The person in there refers to the distance with the range of a person. Among the names they were considering were variations on PAN for personal area network. ![]()
