Here are a few things you'd want to know about Bluetooth...

1. Bluetooth by nature is a short-range wireless technology.

Bluetooth was initially made specifically for wireless headsets hence its “range” was never meant to be anything more than the length of a typical backyard.

2. Bluetooth Signals are easily interfered with.

Much like almost any other modern wireless technology, Bluetooth signals can be negatively affected by things like walls, floors, other wireless devices, or even a human body.

If you want a better range & less interference, try to stay clear of the things mentioned above.

3. There are two types of Bluetooth.

In short, they are “Class 1” and “Class 2.”  Class 1 has better range (100m/300ft) but drains your battery faster, whereas Class 2 has a shorter range (10m/30ft) but is more efficient when it comes to battery usage.  

4. The “Actual Range” depends on a lot of things.

Things that can affect the range: Bluetooth version, Bluetooth type, Bluetooth profile, Brand & make, where you’re using it, what’s around you… etc and many more. Getting a bad range doesn’t necessarily mean your device is bad; try it elsewhere before you give it a conclusion.

5. The “Transmitter” and the “Receiver.”

Every Bluetooth connection consists of a “transmitter” and a “receiver.” The “transmitter” sends the signals to the “receiver.” In a typical Bluetooth headphone connection, your phone is the transmitter and the headphone is the receiver.

There are cases where one device can do both, but it is unlikely that they’ll be able to do both at the same time.

Here are some examples:

• Transmitters: Phone, Computer (can sometimes use as receiver), TV.
• Receiver: Headphones, Speaker
