The source of interference can be "jamming" a certain frequency band, or it can be a wide variety of communication technologies that simultaneously undermine the security system.

For example, Ajax uses 5 frequency bands for communication:
2G/GSM (900/1800 MHz), 3G/UMTS (2100 MHz) and LTE (900/1800/2600 МHz, depending on sales area) networks of cellular operators
Wi-Fi network (2.4 GHz)
Jeweler Radio (868.0–868.6 MHz or 868.7–869.2 MHz, depending on region)
Broadband jammers that can interfere with multiple networks simultaneously (for example, Wi-Fi and GSM) can be:
Handheld or portable wifi signal jammer, the size of a mobile phone, the power consumption is relatively low; therefore, they block data transfer within a distance of 5-15 meters (without obstructions).
