Description

Yellowjacket-Ultra is designed for teams who need to know exactly what’s transmitting on their Wi-Fi spectrum, and where it is.

Why security teams choose Yellowjacket-Ultra

  • See the whole Wi-Fi spectrum. Covers 2.4 GHz, 5.8 GHz and 6 GHz Wi-Fi, so you know exactly what is transmitting and where.
  • Catch impostor networks. Built-in evil twin detection flags access points impersonating a legitimate network.
  • Make quiet devices talk. The active ping feature forces hidden devices to communicate so they can be located.
  • Walk it down. A direction-finding antenna narrows down the physical location of a threat.
  • Built for secure sites. A hardware isolation switch keeps the charging port separate from data transfer, and data exports in a Wireshark-compatible format.

Applications

  • Government and correctional facilities: finding rogue access points and hidden clients.
  • SCIFs and boardrooms: security sweeps of sensitive spaces.
  • Medical centres: checking for unauthorised wireless devices.
  • Wireless security audits: mapping what is on your Wi-Fi spectrum.

FAQs

What does “evil twin detection” mean?

It flags access points that are mimicking the name or credentials of a legitimate network, a common tactic used to intercept traffic.

Can it find a device that’s deliberately staying quiet?

Yes, the active ping feature forces hidden devices to respond so they show up and can be located.

Is it suitable for use in secure or classified facilities?

Yes, it includes a hardware switch that physically isolates charging from data transfer, and supports Wireshark-compatible data export for controlled analysis.

Where is it typically used?

Government and correctional facilities, SCIFs, boardrooms, medical centres, and general wireless security audits.

Which frequency bands does Yellowjacket-Ultra cover?

2.4 GHz, 5.8 GHz and 6 GHz Wi-Fi, within a coverage range of 690 MHz–2700 MHz and 4.9–5.9 GHz.

How long does the battery last?

4–5 hours of typical runtime, with a USB-C recharge in under 5 hours.

Is it rugged enough for field use?

It has a water-resistant, high-impact ABS housing and weighs 3 lbs with the antenna.
