Bluetooth 5 provides, for [[Bluetooth Low Energy|BLE]], options that can double the data rate (2{{nbsp}}Mbit/s burst) at the expense of range, or provide up to four times the range at the expense of data rate. The increase in transmissions could be important for Internet of Things devices, where many nodes connect throughout a whole house. Bluetooth 5 increases capacity of connectionless services such as location-relevant navigation<ref>{{cite web|url=http://www.computerweekly.com/news/450298598/Bluetooth-5-standard-brings-range-speed-and-capacity-boost-for-IoT|title=Bluetooth 5 standard brings range, speed and capacity boost for IoT|access-date=18 June 2016|archive-date=18 June 2016|archive-url=https://web.archive.org/web/20160618143744/http://www.computerweekly.com/news/450298598/Bluetooth-5-standard-brings-range-speed-and-capacity-boost-for-IoT|url-status=live}}</ref> of low-energy Bluetooth connections.<ref>{{cite web|url=https://www.bluetooth.com/news/pressreleases/2016/06/16/-bluetooth-5-quadruples-rangedoubles-speedincreases-data-broadcasting-capacity-by-800|title=Bluetooth 5 Quadruples Range, Doubles Speed, Increases Data Broadcasting Capacity by 800% – Bluetooth Technology Website|website=bluetooth.com|access-date=12 December 2018|archive-url=https://web.archive.org/web/20181209055417/https://www.bluetooth.com/news/pressreleases/2016/06/16/-bluetooth-5-quadruples-rangedoubles-speedincreases-data-broadcasting-capacity-by-800|archive-date=9 December 2018|url-status=dead}}</ref><ref>{{cite web|url=https://arstechnica.com/gadgets/2016/06/bluetooth-5-spec-coming-next-week-with-2x-more-range-and-4x-better-speed/|title="Bluetooth 5" spec coming next week with 4x more range and 2x better speed [Updated]|date=10 June 2016|access-date=14 June 2017|archive-date=10 June 2019|archive-url=https://web.archive.org/web/20190610041359/https://arstechnica.com/gadgets/2016/06/bluetooth-5-spec-coming-next-week-with-2x-more-range-and-4x-better-speed/|url-status=live}}</ref><ref>{{cite web|url=http://www.techradar.com/news/networking/bluetooth-5-everything-you-need-to-know-1323060|title=Bluetooth 5: everything you need to know|date=10 June 2016|access-date=11 June 2016|archive-date=5 May 2021|archive-url=https://web.archive.org/web/20210505011821/https://www.techradar.com/news/networking/bluetooth-5-everything-you-need-to-know-1323060|url-status=live}}</ref>
