Interference Analysis of GPS Jammers to Wireless Communication System

With the widespread use of the Global Positioning System (GPS), the use of GPS jammers is becoming more and more common. However, GPS jammers can interfere with wireless communication systems, thereby affecting communication quality and performance.

1 Introduction

Wireless communication systems play an important role in modern society, allowing us to transfer information quickly and communicate over long distances. The Global Positioning System (GPS) is a technology commonly used in navigation, positioning, and time synchronization. However, with the advent of GPS jammers, wireless communication systems may be disrupted, resulting in loss of communication and reduced quality.

2. How GPS jammers work

A GPS jammer is a device used to jam and disrupt GPS signals. It usually works by sending jamming signals to suppress or override GPS signals. These interfering signals can be broadband signals transmitted in the GPS frequency band, or narrow-band signals. These jamming signals can be sent in random or regular patterns to mislead or interfere with GPS receivers.

3. GPS jammers interfere with wireless communication systems

The use of GPS jammers may cause the following types of interference to wireless communication systems:

3.1 GPS receiver failure

The interference signal of the GPS jammer can suppress or shield the GPS signal, causing the GPS receiver to fail to work normally. This means that the wireless communication system cannot obtain accurate GPS positioning information, which may cause positioning errors and communication interruptions.

3.2 Signal Interference

The interference signal sent by the GPS jammer may interfere with the frequency band used by the wireless communication system, resulting in a decrease in the quality of the communication signal. This can cause issues such as communication interruptions, increased packet loss, and slower communication rates.

3.3 Multipath Interference

GPS jammers may introduce multipath interference, that is, signals undergo reflections from multiple paths during propagation, resulting in overlapping signals. This may lead to an increase in bit error rate and a decrease in communication performance.

4. Solutions

In order to reduce the interference of GPS jammers to wireless communication systems, the following solutions can be adopted:

4.1 Technical Optimization

The wireless communication system can be optimized through technical means to make it more resistant to interference. For example, adopt higher frequency communication frequency band, use more advanced modulation and demodulation technology, increase error correction capability, etc.

4.2 Filtering and blocking

Filters and shielding devices can be used to block the jamming signals of GPS jammers to protect wireless communication systems from GPS jammers.

4.3 Regulations and laws

Governments can issue regulations and laws to limit and regulate the use of GPS jammers. This will help reduce the use of GPS jammers and their interference with wireless communication systems.


The interference of GPS jammers to wireless communication systems is a concern. Not only can it lead to communication disruption and degradation, but it can also negatively impact applications such as positioning and navigation. Therefore, we should adopt corresponding solutions to reduce the use of GPS jammers and interference to wireless communication systems.
