This is presumably because, to date, there haven&#8217;t been many long range end-user products. There aren&#8217;t many devices out there because you need Bluetooth 5 hardware at both ends of communication and existing devices can&#8217;t be upgraded. <\/p>\n\n\n\n<p>Device manufacturers have been waiting for the &#8216;device at the other end of the communication&#8217; (beacons, sensors, smartphones, single board computers) to become compatible before creating new products using Bluetooth 5 which is a chicken and egg situation. There are also tradeoffs around backwards compatibility and battery power. It&#8217;s more complex to create a device that supports Bluetooth 5 and is backwards compatible with Bluetooth 4. Advertising both at the same time uses more power and hence reduces the battery lifetime.<\/p>\n\n\n\n<p>In order to validate Bluetooth 5&#8217;s long range claims, Nordic have a <a rel=\"noreferrer noopener\" aria-label=\"new blog post testing long range (opens in a new tab)\" href=\"https:\/\/devzone.nordicsemi.com\/nordic\/nordic-blog\/b\/blog\/posts\/testing-long-range-coded-phy-with-nordic-solution-it-simply-works-922075585\" target=\"_blank\">new blog post testing long range<\/a>.
