It’s important to understand the differences. Despite their similarities, they are not identical. WiFi and Bluetooth are so similar that they are often confused. Other ways of sending signals between devices work in different ways, have different purposes and are only available on certain devices. Knowing what Bluetooth is also requires knowing what it is not. It’s also one of the most important, as not knowing the network or signal of the device in question can make it impossible to interfere with it. If two or more piconets combine, a scatternet is formed.įinding a device on a piconet and/or scatternet is the first step in blocking Bluetooth signals. This ensures that they don’t use a frequency that’s already been taken by another device.īluetooth signals can form a connected network of up to 8 devices known as a piconet. This allows them to have their own designated signals so they don’t interfere with other critical technology like medical devices.īluetooth signals use a technique known as spread-spectrum frequency hopping to quickly change channels. It’s important to understand how Bluetooth signals work before trying to block them.īluetooth devices can use any of 79 different unique frequencies or channels. Since it’s relatively new, not everyone may understand it even if they use it every day. What Is Bluetooth?īluetooth is a common technology that’s present in all sorts of modern devices. Read our guide to Bluetooth jammers to learn what Bluetooth is and how to block it. This can increase security, prevent solicitation, and provide other benefits. The Bluetooth jammer is the easiest one because it is designed for this purpose.īy emitting an identical signal, jammers interfere with the functioning of other nearby devices. There are as many options for how to block Bluetooth signals as there are devices that can access them. While this makes it easier for them to communicate, it can also cause security issues. Almost all modern devices are capable of emitting Bluetooth signals.
