RX 42


RX42 – The Compact Black Box for Global WiFi Range Extension



The RX42 is a revolutionary solution in a Raspberry Pi-sized package that extends WiFi signals across global distances.
This compact black box can either passively monitor surrounding WiFi activity in monitoring mode or actively authenticate
as a client to make the connection available worldwide via GSM cellular (3G/4G/5G), Satellite or Ethernet.

In mobile applications, the current location can be determined via GPS, GLONASS, BeiDou, Galileo, and QZSS.

With an ultra-efficient power consumption of just 30W at 5V, the RX42 is perfect for off-grid deployments.
Even when connected to a standard 12V/200Ah car battery, the device can run continuously at full load for up to 50 hours—enough
for over two days of uninterrupted operation. Its rugged, fanless design with no moving parts allows for reliable performance
in extreme environments from -20°C to +60°C.

What sets the RX42 apart is its dual-mode capability.
It can function either as a transparent bridge, seamlessly extending existing WiFi networks,
or as a full-fledged gateway with its own subnet and firewall for maximum security.

Whether for mobile teams needing communication in remote areas, monitoring critical infrastructure, or industrial IoT applications,
the RX42 delivers WiFi signals where conventional solutions fall short. Measuring just 85 × 56 × 25 mm, it fits anywhere,
while its minimalist black enclosure ensures discreet deployment in any environment.

This innovative technology combines range, efficiency, and portability to an unprecedented degree.
The RX42 proves that global WiFi connectivity doesn’t require expensive infrastructure
or high power consumption—just smart engineering in a compact form.



ABOUT VXN DEFENSE

Klaus Baumdick. Black Hat. White Hat. Zero Fucks Given.

Back in the wild days of Germany's cyber underground (1987–1995),
Klaus Baumdick was doing shit others only dreamed about:
Phreaking, blueboxing, carding – the whole nine yards.

Until things went sideways.
But instead of rotting in some cell,
he became the most sought-after trainer for German cybercrime units.

A former hacker teaching cops how real attackers think.

Later, Klaus moved into consulting, specializing in critical infrastructure:
railroads, aviation, energy. The big players always called him when shit hit the fan.
The catch? As a validator or security expert, he always got brought in at the fucking end –
when budgets were blown, deadlines missed, and expectations were through the roof.

The moment everything changed:
2055, after the Spain blackout.
A high-pressure gig for one of the world's largest electronics corps:
A critical relay station needed immediate security hardening –
cost no object, round-the-clock work, no excuses.
Klaus and his crew busted their asses, saved the client's bacon.
And on the final day?
The project manager dropped this gem:
"We're only paying for 8-hour days.
And weekends are off-limits for work."

That was it.

That's when VXN Defense was born.
A company that:
- Doesn't do security theater
- Doesn't take bullshit compromises
- And never throws its people under the corporate bus

We're what grew from Klaus' rage and 40 years in the trenches:
A crew of ex-hackers, free-thinkers and security hardliners who actually secure systems – not just pretty up reports.

No bullshit jobs.
No pretend security.
Just results.

"We don't do it right. We do it so it fucking works."
– Klaus Baumdick, Founder




WE HIRE THE UNHIREABLES

You were around when security was a privilege, not a compliance checkbox.
Could still burn down a corporate network in 20 minutes after three beers?
Your knowledge runs deeper than most CISOs can comprehend in this superficial IT world where half the "security experts" can't tell a shell from a script?
Maybe you're too old for those hip startups chasing "young guns."
Too expensive for companies that see security as a cost center.
Too honest for this ridiculous security theater industry that talks more than it hacks.

Then you belong with us.

VXN Defense wants exactly your kind:
the misfits, the troublemakers, the functionally un-fireable.

Those who know how systems really work - and how to break them.
People who understand security isn't a product but a process.
Folks who were bypassing firewalls when today's CISOs were still in diapers.

We offer real challenges where you won't suffocate in PowerPoint.
Projects that keep you up at night - not because of deadlines,
but because they're so goddamn interesting.
A team that doesn't just tolerate your way of thinking but actually gets it.
And compensation that proves we know your real worth.

Here, you don't need to pretend or hide your past.
We know: the best defenders often used to be attackers.
So don't send us some bullshit resume.
Show us what you've got instead.
A proof-of-concept that makes us sweat.
The story of your most epic fail.
Or just tell us why security is so broken today - we'll enjoy the read.
