Will a jammer block one frequency or multiple bands at the same time?

Hello everyone! I don't know much about jammers, so I want to know how they work-do they block only a single band or several bands at the same time?

When the electronic jamming equipment industry was just beginning to develop, signal jammer were used to block a single frequency band. Later, with the development of these useful interference devices, more and more frequency bands were added to the list, and new types of jammers were developed and manufactured. They have very few antennas, so they can only block very few signals at a time.

The most popular combination of blocked frequency ranges is a combination of frequencies in a certain frequency band. For example, GSM frequencies (such as GSM850, GSM900, GSM1800 and GSM1900) are no longer blocked individually, but are blocked together by signal jammers. More and more frequencies are added to the interference list, and new types of jammers have been created, such as WiFi/Bluetooth/3G/GSM jammers, 4G/LoJack/XM radio jammers, and even multi-frequency desktop jammers.

As you can see, modern technology is not standing still and is constantly improving to provide us with awesome new features.
