![]() Three Ring doorbells side-by-side in a store.Īs you can see from the table, all but the relatively expensive ‘Elite’ model (which is Power over Ethernet) use wireless. I obviously won’t be talking about specific jamming devices or how you can use/buy them – this article is purely to help you understand the risks and how to avoid them so that your Ring Doorbell install (which is as much as security device as a convenience device) isn’t useless when you most need it. It is worth noting that Wi-Fi jamming attacks are highly illegal and regularly investigated by the FCC, but they are sometimes used by organized crime to help breaking into properties by blocking wireless signals (such as from ‘smart’ WiFi cameras) so their theft won’t be recorded.Īs a result, I wanted to write this article to discuss WiFi jammers more. A detailed study in January 2021 by Michigan State University found that Wi-Fi, ZigBee, Bluetooth and cellular data can all be jammed fairly easily with various jamming attacks:ĭespite the significant advancement of wireless communication and networking technologies in the past decades, realworld wireless communication systems (e.g., Wi-Fi, cellular, Bluetooth, ZigBee, and GPS) are still vulnerable to malicious jamming attacks. ![]() They basically ‘shout’ loads of (radio) noise out, just like if you stood behind a radio commentator and shouted into their microphone, no-one listening at home would be able to understand anything. Since WiFi is just radio waves, if there’s suddenly loads of extra ‘traffic’ on the 2.4 Ghz and 5 Ghz bands, there will be no way for the wireless signal to effectively get from the device to the receiver.Īnd that’s exactly what a wireless jamming device is. Now it’s worth clarifying that I mean a lot of radio noise. In normal circumstances, walls and buildings will reduce the signal strength, but you should still be able to use WiFi over 150-300 feet.īut if there’s suddenly a lot of ‘noise’ in a local area, there is no longer a clear path. However WiFi – which is just radio waves either at 2.4 Ghz or 5 Ghz frequencies – relies on a fairly clear path between the device (such as a phone or smart home device) and the receiver (such as an internet router). ![]() This is used by phones and laptops when out and about, and also by dozens of devices around the home. Wireless (also called WiFi) is a great invention, offering the ability to easily access the internet without a physical Ethernet connection.
