Bluetooth was originally designed to exchange lots of data at close range in continuous streaming data applications!
The devices can send and receive data at the same time. This is perfect for many common consumer products such as computer headsets where the two devices are close to each other whether running MS Windows, APPels MAC-OS, Linux, Android, ....!
In normal use, 10 meters is a good indication of what can be achieved between two Bluetooth devices indoors.

There are many factors that affect Bluetooth range, such as transmitter output power,
Receiver sensitivity, Physical obstacles, The antennas, .....!
While the radio performance and antennas are fairly static for a given Bluetooth device, the environment can vary greatly. Outdoors, in an open field, you can easily achieve a range of up to a hundred meters. But this is a rare situation. Indoors, obstacles such as concrete walls will dampen the radio signal and the effective range will be drastically reduced.

While basic Wi-Fi/WLAN is handy for everything, dont use it, or at least only use it when necessary Wi-Fi is ubiquitous these days, but that doesnt mean
