Homonym: jammers (Sports)
Jammers are devices designed to disrupt or block communication signals, such as those used in mobile phones, Wi-Fi networks, and GPS systems. They work by emitting radio frequency signals that interfere with the normal operation of these devices, preventing them from sending or receiving information. Jammers can be used for various purposes, including security, privacy, and military applications.
While jammers can be effective in certain situations, their use is often restricted or illegal in many countries, including the United States. This is because they can interfere with emergency communications and other critical services. As a result, individuals and organizations must be cautious and aware of the legal implications of using jammers.
