· Jammer: Negatively impacts others by blocking their communications (e.g., a jammer in a café stops all customers from making calls).
· Booster: Positively impacts others by improving signal quality for everyone in the coverage area (e.g., a WiFi booster helps all residents in an apartment building).
Example:
If you’re in a remote cabin with no cell service, a booster would pick up the weak signal from a distant tower and let you make calls. If you’re in a prison and want to stop inmates from using cell phones, a jammer would block all signals in the facility.
In short, the fundamental difference is their purpose: jammers block signals to prevent communication, while boosters amplify signals to improve it.
