December 10, 2010 — The fourth version of the Bluetooth protocol, known as Bluetooth Smart or Bluetooth Low Energy (BLE), is placing a new focus on the Internet of Everything (IoE). The Bluetooth SIG (Special Interest Group) recently unveiled several of the IoE features being added to Bluetooth in 2016.
The planned upgrades include improvements in data transmission range and speed (four- and two-fold increases, respectively) without increasing energy consumption. The current version of Bluetooth Smart supports ultra-low peak, average and idle mode power consumption, allowing Bluetooth devices to run for a month on standard coin-cell batteries, the organization says. The Bluetooth standard can typically transmit data over a distance of 32.81 feet, but has the potential to send information up to 109.3 yards.
This is good news for a number of industries, wearables being one, which will now be able to better connect to the variety of small cell networks, such as smart homes, industrial automation, smart infrastructure, and mission-critical devices used in medicine and hospitals, while maintaining long battery life, according to the Bluetooth SIG.
July 23, 2015 — The white-hot market that is beacon technology got another boost this week when Google unveiled Eddystone, a new and open format for Bluetooth Low Energy (BLE) beacons for anyone to use.
BT beacons may be the fastest moving technology of the small cell landscape. Beacons are designed to be discoverable by any nearby Bluetooth Smart device, via its identifier, which is a public signal. But, of course, that raises the privacy red flag. To address that, there is a built in a feature called Ephemeral Identifiers (EIDs) which change frequently and allow only authorized clients to decode them. EIDs will enable you to securely do things like find your luggage once you get off the plane or find your lost keys.
Google’s entry into the beacon space is a validator. It is another in a long line of stamps of approval from the industry that this technology is not going away. Apple, Google, Facebook and Twitter all have dedicated resources to Bluetooth Low. That is music to my ears – about time they came up with something I can really use.
