Data protection is important! Many of our customers buy jammers primarily to protect their privacy and information security. Today we talk about the data protection that jammers offer.
Our personal information, location data and communication content can be tracked, collected or monitored. Faced with this situation, some people began to consider the use of jammers to block wireless signals to protect their privacy. With the increasing consideration of privacy issues, we understand that not only individuals but also many companies are increasingly paying attention to the use of jammers to protect privacy in everyday life.
Why should people use jammers to protect their privacy?
1. prevent tracking and monitoring
Modern cell phones, auto-GPS and IoT devices continuously upload user location information and may collect data even without explicit permission. In my previous articles "Are GPS jammers effective against trackers?" and "To block the GPS tracking of your vehicle" I wrote about how to prevent trackers. You can also read it.
Signal jammers can block GPS, Wi-Fi and cellular signals to prevent location tracking and reduce the risk of data loss. This does not mean that you have to use the purchased jammer frequently. I think you can use the purchased GPS jammer if you suspect that you are being followed.
2. prevent eavesdropping and data interception
Public Wi-Fi networks are vulnerable to attacks by people with suspected malicious intent and users' login credentials, chat logs and bank details can be stolen.
By using a jammer, wireless communication signals can be jammed to prevent unauthorized monitoring or data leaks. If you want to know which frequencies need to be jammed to prevent eavesdropping, you can "Case analysis of the scenario of the decision to buy jammers (part 1)", where I analyze the frequencies of the signals from the listening devices.
3. protection of personal space
In a conference room, office or at home, there may be a risk of unauthorized recording devices or smart speakers listening in. Our product SDP16DT is suitable for large conference rooms and offices.
Interfering with radio signals can restrict the remote control and data collection of smart devices and thus improve data protection.
4. control digital distractions and improve your concentration
Many schools, conference rooms and movie theaters want to reduce the distractions of cell phone use so people can focus more on face-to-face communication. Has your school started using jammers? Regarding the content of school jammers, "Is it necessary to use a cell phone jammer in the examination room?" and "The role of cell phone jammers in schools" provides more detailed analyses.
Precautionary measures when using jammers
The following problems should be avoided when using jammers:
Avoid interfering with other people's normal communication
I must tell you that jammers not only interfere with your devices, but can also interfere with the cell phone signals of people around you and prevent them from making phone calls or surfing the Internet. Therefore, if you use a jammer, you must be careful not to interfere with the normal lives of others.
In fact, most jammers do not interfere with other people's normal lives. If you read my previous article "The influence of wall materials on the penetrability of signals emitted by cell phone jammers", you know that jammers can't penetrate walls to work. Do you understand? The jammer only works in one room and does not normally affect other rooms.
Alternatives to jammers
You don't have to rely on signal jammers to protect your privacy. If you don't want to buy a jammer, I recommend you try the following methods:
- Use a jammer bag (Faraday cage): Place your phone in a jammer bag to block all radio signals. Let me explain this in detail. Faraday cages can interfere with wireless communication signals such as Wi-Fi, cell phone signals (4G/5G), Bluetooth, GPS, etc. However, if your Faraday cage is not completely closed, e.g. if the holes in the metal mesh are too big, some radio frequency signals can still get through.
- Switch off GPS, WLAN and Bluetooth: Turning off all signals will definitely reduce the possibility of your device being tracked and monitored.
- Use encrypted communication apps: I also recommend that you use encrypted communication apps to ensure secure information transfer and prevent data leaks.
- Customize the device's privacy settings: We know you can set privacy permissions on devices like cell phones, but some people are too lazy to set them up. You can set them up! This can limit the app's permissions and reduce unnecessary data collection.
