Use of jammer prove



  1. When a retail store (in Austria) uses a signal jammer, colloquially also called handy jammer. does this have to be declared at the entrance?
  2. Does this load need / need an authorization?
  3. If so, who will issue them and will they even be issued?


I recently noticed “strandln” in a shop that I did not receive with either yesss or hot.

That’s why I’ve equipped myself with 3 phones all 3 in each one of the nets are booked and full LTE receipt BEFORE the door of the shop. on all three phones automatic network selection was set in all networks (2G 3G 4G). after entering the shop gradually no network (ZERO not even emergency call possible I’ve tried) with none of the three devices – suspected> annoying MY OPINION AFTER. I can now hard to write which load it goes. mmn is not so built that should not be possible at least make phone calls. If you approach a window in the store, no matter which floor is there but BUT no traffic.

which I have also observed, there are ONLY cordless phones no cordless.

The shop has 3 or 4 floors.


I would now be interested in whether the mobile phone jammer operate and how to prove it. is not legal or right?


So to think a jammer right to think I’m not right.

I can say I work in a steel construction and look at the transmitter. Since the windows are also steamed. All 3 providers have at the window LTE reception with LTE-A. 1 meter away from it then LTE-A is off at TMA. 2 meters in the room purely, LTE-A at all away. 4 meters in the room purely TMA has still weak LTE reception, A1 a little better, Three is already on EDGE. 6 meters in the room purely TMA jumps on EDGE, A1 goes on 3G which is also clear, since we have indoor transmitters which 3G can.

Three and TMA have in the middle of the building already problems with a general reception and sometimes even dead spots.

  1. the company is in the middle of Linz. If I open the window then the reception is much better.

Basically, one has to say that in the commercial sector, the structural conditions very often hinder radio more than in the private sector.

Reinforced concrete structures and metal-coated panes strongly attenuate and are often used in business premises. You even notice when the front door opens and closes.

If, on the outside, the signal is already weak, it may well be that nothing is receivable inside.

If it’s really possible to have a reception in front of the door and not even 2G inside, that’s weird (but possible).

You can write a complaint to the Telecommunications Authority – they may measure that.
