You
can barely find something that doesn't have a myth, history or legend
associated with it. However, the question many often ask is whether the
myths they hear are true or false. Since Bluetooth became popular, there
have been so many beliefs that people have held on to about this
amazing technology. And this is the time to drop some of these beliefs
or myths.
Non-discoverable Bluetooth is secured
Your Bluetooth is not secured even if it cannot be found by other devices so the best option is to switch off your Bluetooth when it's not in use. If your Bluetooth is on, your phone can be hacked because your Bluetooth Device Address (BDA) might be hidden in non-discoverable mode and hackers can take advantage of this loophole.
Enabling Bluetooth kills your battery
Many people believe that immediately they switch on their phone's Bluetooth, they begin to lose battery. This actually false. Even if the Bluetooth icon stays on for hours, it has no impact on the battery. This is because many smartphones now come with Low Energy Module which allows you to use your Bluetooth without your phone shedding any battery.
Bluetooth is not good for your health
Health experts are yet to agree on whether the radiation from your smartphone is harmful or not. This is same with Bluetooth which is one of the reasons why Bluetooth headset is becoming popular as it is safer than receiving calls with your phone.
Bluetooth only functions in small rooms
Bluetooth devices can work anywhere, including a small room. The only problem is the operating distance between the devices. However, this may not be an issue anymore as there are now three classes of Bluetooth that can transfer files over a wide distance range. Bluetooth Class 1 devices have a range of around 100 metres, Bluetooth Class 2 devices have a range of around 10 metres and Bluetooth Class 3 devices have a range of less than 10 metres. Most smartphones and smartphones and tablets use Bluetooth Class 2 or 3.
Bluetooth interferes with WiFi
Most wireless technologies including Bluetooth and WiFi use 2.4 GHz radio frequency to exchange data. Due to this, many people have the perception that the Bluetooth and WiFi often clash because they are broadcasting on the same wireless frequency. This is not the case because Bluetooth is super-fast as it hops over other devices to prevent any interference without dropping in speed.
