199569 2003-12-11 19:41:00 I have been looking at these for a while now and have found a source in the UK that can supply a unit that looks like a cellphone has a 30metre jamming range and appears to work in our NZ cellphone frequencies .

So of course I want one and was hoping to import a number for sale locally . However it occured to me that it might possibly be illegal to use such devices so I go looking for the rules .

I found his on the telepermit . co . nz site .

"2 . CELLPHONE "JAMMERS"

We have recently had some enquiries about the use of cellphone "jammers" in New Zealand . Interest in these devices has arisen because they appear to be a means of avoiding interference (and annoyance) to other patrons in lecture theatres, cinemas, concerts, etc, due to cellphones ringing at inappropriate times . Some means of allowing the proprietor of the venue to completely block cellphones seems a good idea - until other issues are considered .

Unfortunately, like any other radio signals, the signals from cellular jammers are difficult to constrain wholly within the intended venue . If they are to have sufficient power to totally block cellphone use within the venue, they are also likely to affect customers outside, but close to that venue . At greater distances, while they may not totally block cellphone use, they can still cause serious service degradation for users . Those that do have sufficient power to be effective are also likely to create a hazard for any persons who are close to the antenna .

A further complication is that jammers are not "absolute" in their effectiveness . Because of radio wave propagation effects within the venue, there can still be locations which are unaffected by the jammer . This can be overcome by using multiple jammers, but this only worsens likely outside interference .

From a mobile network operator's viewpoint, interference needs to be avoided wherever possible and Telecom could certainly not condone the free sale and use of such devices . There may be special circumstances where such devices could be justified, but careful design would needed . Unauthorised use of such devices would be in breach of the Radiocommunications Regulations .

The net result is that Telecom, as the official manager of its mobile spectrum, will not Telepermit cellphone jammers to be operated on its frequencies without specific site authority . Even then, very few circumstances are expected to justify the use of such devices .

The simple (although not always effective) solution is for customers to be asked to ensure that they have turned off their cellphones in any situations where ringing cellphones would be an unwarranted nuisance to other persons . "

So it would appear that jammer use is not allowed under our Radiocommunications Regulations but there does not appear to be any laws against selling them just using them .

So technically I could sell them without hassle (it is then up to the buyer as to whether they want to break the law by actually using the device) .

So what do you reckon . Would it be a good idea to bring some in or not? Would you be interested in a cellphone jammer with a 30 metre range for use in your home or business?

199570 2003-12-11 19:51:00 I'd be happy for one with a THREE metre range when I'm in a cafe.

Have you noticed people talk a lot louder when they on a cell phone?

199571 2003-12-11 20:48:00 funny how there seems to be a grey aera with Radiocommunications Regulations, you can buy the stuff just not use it. there seems to be quite a large amount of products which fall under this ;-) tweak'e (174)

199573 2003-12-11 21:04:00 lol - but would they get called in the first place? just make like the mcdonalds ad - take their phone and put it in a glass of water :D Growly (6)
199574 2003-12-11 21:09:00 and just like on the ad, you'd get your head pounded in. somebody (208)
199575 2003-12-11 21:16:00 Lets just say that if I was waiting for a call that could be life or death and you jammed my signal and I found out then I would come and smash your head in.

Nobody has the right to block a legel device from working unless it is on their property and warnings have been made and with a range of 30 metres you will be affecting quite a few people.

199576 2003-12-11 21:32:00 A cellphone Booster, now that'd be cool...

A mate had one at his house once for the Vodafone network... Was real cool having the cellphone show my signal coming from "Nowhere".

199577 2003-12-11 21:44:00 Absolutely stupid idea in my opinion. It could be useful in a prison to prevent unmonitored outside contact, but I think they prefer to just hunt out the person with the cellphone and punish them.

Most people do actually think of other people. I know that myself and everyone else I know with a cellphone put them on silent at the movies, lecture theatres, etc. If you were to block cellphones you'd need a HUGE sign on the door at point of entry to let people know, just like the "all staff may check your bag".

199578 2003-12-11 22:32:00 Last time I enquired about a cell phone booster was in DSE. They had one there the trouble was it cost about $800
I think I would be putting that jammer in a jug of water.
