This is why it’s important to know how to block Bluetooth signals. If a malicious and/or annoying caller comes from a particular network, it may be necessary to prevent it from accessing your device. Numerous devices now have Bluetooth capabilities, so the jammers can work on anything from a cell phone to a speaker. They can block anything from a cell phone to a wifi network.Ī Bluetooth signal jammer blocks a Bluetooth signal. They can also lessen unwanted calls and keep infected networks from spreading malware. They prevent phone usage in restricted areas like jails or restaurants. They do this by sending out noise that interferes with other devices in the area. What Is a Bluetooth Jammer?Ī jammer is any device that blocks the signals of electronic devices. Check out our other articles for the benefits of a WiFi jammer and browse our collection of available WiFi jammers today. Bluetooth requires a close connection of fewer than 30 feet, while wifi can spread across a 300-feet range.ĭue to their similarities, most WiFi jammers also have the ability to block Bluetooth signals. WiFi is for accessing the internet, while Bluetooth is for connecting devices.Īnother important difference between the two signals is the distance they can spread. The difference lies in which devices can send out these signals, as only a wireless router can provide WiFi for another device.īoth WiFi and Bluetooth provide wireless communication but for different purposes. WiFi signals can be used by almost any modern device, from cell phones to laptops. It’s important to understand the differences.

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.
