Hey people I am in need of some RF experts help .

here is the situation my school has some stupid remote things to take attendance and participation points .
The system CAN BE SEEN HERE .

What I am wondering is if anyone can determine anything about it from the numbers on the back

which are
FCC ID: R4WRCRF01
ACN 107 654 697
IC: 5994A-RESCARD


What I need to know is what frequency range this thing is running on and if it can be jammed . Any help would be appreciated .

On another note these remote things suck because
1. they do not allow you to miss class
2. they do not allow you to sleep during class
3. I hate them



EDIT:

I have dissasembled it and taken a pic HERE

Now the picture is blurry but the white text on the top says
Responsive
Innovations
RCRF-01 ( does that mean anything???)
Ver 2.0A

And the main chip running to the antenna reads

nordic
nRF24E1G
AD0521

Hopefully that helps more .


*Update*

Phisrow found the operating range HERE

And it turns out these things operate on a standard 2.4 ghz band . Just like portable phones wireless video camers and some WIFI .

So their are pleny of jammers out there they are just EXPENSIVE

Anyone know of a cheaper solution ???

EVEN More

THIS ONE BLOCKS EVERYTHING for 445 bucks

Bump for a worthy cause. One thought might be that since its RF its protected by the FCC? I think its illegal to make jammers for certain freqs.

Anyways, maybe someone knows more.
