Comparison of common and high-quality wifi jamming technology

Admin Posted on 2022-11-09

1. Ordinary shielding:

Pros: Inexpensive wifi jammer, simple technology

Disadvantages: uncontrollable, large interference: interference to the surrounding, interference to the base station, large radiation, short life.

Technical features: A large number of low-power or high-power devices remain on simple technical solutions.

Second, high-quality shielding:
Advantages: moderate price, good wifi jammer effect, low radiation, high reliability.

Disadvantages: no detection and positioning function, easy to be misled and misunderstood, slandered, large radiation, leaks, interference

Technical features:

1. Adopt strong signal digital point frequency hopping technology, high efficiency, 150 times less radiation than ordinary shielding technology.

2. Outdoor shielding is mainly used to improve efficiency and reduce indoor radiation power by hundreds of times.

3. Multi-channel combining technology, full-frequency antenna replaces N frequency division antennas, suitable for wireless remote, laying the foundation for distributed antennas.

4. Distributed antenna technology, rationally distributes shielding power, spread the power signal, reduces antenna radiation, provides dozens of times efficiency, and eliminates dead spots and leaks at the same time.

5. Jammer mart has a unique TD synchronization technology. For China Mobile's 3G (TD-SCDMA) and 4G (TD-LTE) networks, it only blocks downlink pilot frequency slots, eliminates interference to base stations, and obtains mobile and radio Approved by the management committee, while reducing radiation dozens of times.

Detection + blocking method

power wifi jammer

(1) Ordinary detection

Pros: Inexpensive, nice concept

Disadvantages: frequent failures, high radiation, when detection fails, only shielding equipment can be turned on at all times, false alarms and false alarms.

(3) Pure pseudo base station technology

Advantages 1. It can detect information about the existence of the mobile phone, which is convenient for checking the mobile phone and tracing the mobile phone. source. 2. Small radiation
Disadvantage 1. One can only detect mobile phones using a GSM network. If the cost of the full system is high 2. The surface is reliable, and the mobile phone will fail after the frequency is locked. The mobile phone can make calls, send messages, and surf the Internet without being detected when the mobile phone frequency is locked on 3G and 4G.
