A WiFi signal jammer is a device used to block or interfere with the transmission and reception of wireless LAN (WiFi) signals. It can be used for different scenarios and purposes, including the following aspects:
Security and confidentiality: Some institutions or organizations need to protect the security of their internal networks to prevent unauthorized access. In some situations, such as military installations or government agencies, using a WiFi signal jammer can block the spread of wireless signals, thereby preventing unauthorized personnel from accessing the network.
Privacy protection: In some public places, such as libraries, cafes or conference rooms, using WiFi signal jammers can prevent others from stealing personal information or conducting network attacks through WiFi networks. This practice helps protect user privacy and data security.
Cheating prevention in the exam room: During exams, using WiFi signal jammers can prevent candidates from using wireless devices to obtain improper help or answers. This type of signal blocker typically works within the perimeter of the exam room, preventing candidate devices from communicating with external networks.
Electromagnetic radiation control: Sometimes, specific locations or sensitive equipment may need to limit the use of wireless signals to reduce the potential impact of electromagnetic radiation on human health or other equipment. WiFi signal jammers can be used in these situations to help control the propagation range of wireless signals.
It should be noted that using a WiFi signal jammer may violate local laws and regulations because it may interfere with other people's normal network connections. Before using or purchasing a WiFi signal jammer, be sure to understand and comply with the relevant regulations in your area.
