That's more like it, if this is in a very long hallway, and there are no barriers (walls) between the two BT devices.Īnd while they use different bands and technologies, BT still operates in the very popular, widely used 2.4GHz RF band. Then it claims the range is '40 meters indoors'. Keep reading and it claims (I'm paraphrasing) the effective range is 200 meters. Speaking of 'in theory', I note the specs for BT5.x claim the range is 400 meters! Yeah right. But as soon as distance is needed, the external antenna of the dongle is desired. Internal devices are great for BT devices that will be used in very close proximity to the computer - such as keyboards and mice. External RF devices (BT, wifi adapters, RF mice, etc.) ensure the antenna(s) used in that device are on the outside of the PC's metal case.

This also typically means (to me) to ensure the BT adapter is an external device (like a USB dongle) - that is, something that sticks out and away from the case, and not a device that installs totally inside a metal (which provides excellent RF shielding - not good in this scenario) PC case.
