Olympics Wi-Fi Police

Olympics Wi-Fi Police. They seek unauthorized wifi signals & shut them down… If you bring your own Wi-Fi hotspot to the Olympics this is how they find you.

Active Directional Antenna – 20 MHz to 3000 MHz

Portable directional antenna for tracing signal transmitters and interference sources. Due to its small size and low weight, the Active Directional Antenna R&S HE200 is ideal for portable use.

In conjunction with portable receivers, it allows signal transmitters and interference sources to be reliably detected and localized. The direction is found by orienting the antenna towards the maximum signal level.

The wide frequency range is covered by three frequencyband-optimized antenna modules. The linearly polarized directional antennas have cardioid radiation patterns so that a constant DF accuracy is attained over the entire frequency range.

  1. how can we build something like this ourselves? software defined radio and what type of antenna design that doesn’t cost a year’s salary?

  2. @Jan
    airmon-ng on three different wifi cards that used very directional antennas?

  3. The question is are they watching for 802.11 specifically or just for 2.4GHz stuff in the WiFi channels? Because cheap 2.4GHz “chaff” throwies would be kind amusing to watch them run after.
