How to defend against Wi-Fi and cellular jamming?

@emily_s The OP is asking specifically about WiFi and cellular jamming. The jam detection feature you’re referring to is for the signal between the sensors (entry, motion, etc.) and the base station.  Is there jam (wireless interference) detection for the SimpliSafe’s WiFi and cellular signals as well?

Is there anything to prevent a burglar from jamming the WiFi signal between the base station and router, and from jamming the cellular backup signal, thereby preventing the system from alerting central monitoring and/or sending alerts/texts to users’ phones?

@Boring_Joe​ in part of our article, we discuss how WiFi and cell technology themselves are already resistant to jamming, and defeating them would require highly specialized equipment that most crooks would not really have access to. That's on top of having to know exactly where the equipment is that they want to jam, and also what frequencies all of these transmitters are using.

In terms of just the SimpliSafe system, that's why we always emphasize the importance of layers of security. If you have Outdoor Cameras, you'll be able to spot intruders sneaking around your property and leaving suspicious gadgets before they can even get near. And if they manage to get the WiFi disconnected, the Base Station (assuming you have Monitoring active) will automatically switch to cellular - triggering the warning notification as well. And of course, your local sensors will still be able to trigger the audible alarm. With the right setup, you've got those crooks stopped in their tracks.

@lance843​ I note you mentioned about having more sensors so that it's difficult to jam all of them at the same time, but wouldn't a wide band jammer be able to jam everything within a large area? There are some that can jam everything within a 5000sq ft area, so it would jam all 10 sensors along the way. 

@Boring_Joe​ WiFi and cell stay available at the same time. The very nanosecond that a signal can't be sent through WiFi, the Base Station sends it through cell instead.

I understand that the base station sends a signal the nanonsecond it loses wifi. However, wide band jammers are getting more affordable and easier to obtain nowadays. Would there be a situation where thieves were able to jam both wifi + cell at the same time to prevent the base station sending a signal?

Or for example, if they jammed the cell first then jammed the wifi, the base station wouldn't be able to send out a cellular warning after the wifi went down if 4G was already jammed?
