Ya I remember the big ass cell phones that were JUST phones... Some ppl forget their iPhone 5 can still ring someone lol...

I was referring to landlines hahaha.

on a side note here is a picture of my "first" cell phone. It had 2hr standby time and 20 minutes talk time....YES the battery would last 20 minutes if the phone was in use !! The phone was from 1994 and keep it as a conversation piece. It was used until I was cut off due to being analog and only digital phones would work.

I would certainly love to have one device like this, but, this thing is also really hazardous for human health...
During calls, the cell phones are emitting about 5W of radio power, and those are extremely dangerous... Now imagine the power emitted by this jamming device, probably over 10 Watts...

And I have found an interesting news reports

This device emits 3W of output power total. Less than your cell phone.

So you're driving along to an appointment. Not an area you're familiar with and you're using your cell phone for gps. .

I'd love to own a signal jammer - then again - Illegal is illegal, agreed.

Regarding GPS signals though - MOST cell phones use towers only for better accuracy on GPS.

I didn't think the blockers would prevent a GPS signal which is on an entirely different band, if I understand correctly. Real GPS doesn't require a cell signal.

20 years ago I bought my first dedicated GPS - big yellow Tripmate. Out in west texas there was nothing for cell signals back then..

But the GPS triangulates signal based on time from several sats to the GPS, AFIAK. which is why you need 2 for location and 3 for location and elevation.

Only in America can you own a firearm but not a jammer. It's not like they cause any harm unless you use it to block aircraft or emergency response comm. ---

Aircraft don't use cell phone's they have radios. Same goes for emergency response.
The reason jammers are illegal is you would block someone from contacting emergency services during an emergency.
You would also block that person from receiving an emergency call.

Even if the GPS signal is not blocked, the navigation apps that we use now on our cell phones are very different from the stand alone unit you're talking about.

On one, all the information that can be used is preloaded, on the other, your phone, the information is being continuously downloaded, including traffic. This might not seem like a big deal, but actually saved me at least an hour, probably 1.5 hours over independence day. I was on the way to a friend for a bbq, and was automatically rerouted around 18 different road closures in new york. A friend who used a built in gps in his car wasn't and ended up coming about two hours later... we left within 10 minutes of each other from the same area.

From personal experience circa 2008, using a metro pcs (shittiest service ever) phone with gps, what I ran into, is that if I deviated at all from the course, in an area with no service/signal, you're left with absolutely no directions.

You're in your car. Suddenly your passenger with a heart condition goes limp. You are extremely scared. Ok now you pull out your phone to dial 911. No signal. Try again. Dead. Your GPS isn't working either so you can't find the nearest hospital. You are panicking. You are on a major highway and pulling over is very difficult especially in the panicked state you are in but you attempt to anyway. *Crash*

News later that day: A car with 2 passengers recently attempted to pull over on interstate ___. Passenger ___ was a known case of chronic acute heart failure and an autopsy shows that at the time was having a systolic heart failure around the time of the crash. The driver was most likely panicked when he pulled over and did not put on emergency lights when pulling over. Passerby reports claimed to not have any service for the next 5 miles...

Exactly this is what you should think about before using a signal jammer.
You can't just prejudice and say everyone here just uses their phone for texting on a highway or where ever.

With a signal jammer you negligently restrict other people and maybe even endanger them by blocking 911 or distracting them in another way. For example if you think somebody is careless enough to text while driving why wouldn't people as such do the following *why did my fucking phone stop working Wtf better check right now while driving*

And If those were legal I bet you could not use your phone in any urban area because someone wants to eat in a restaurant without everyone looking on their phones and another one just finds it funny to block others.

Texting while driving is an illegal thing but vigilantism via using a signal jammer isn't the solution to that problem.
For that reason we need official controls and more development in voice control for phones.

If you want to use a signal jammer just because it annoys you that everyone is on the phone nowadays and doesn't talk to eachother. Talk to them! When I meet friends we keep our phones in our pocket most of the time so we can talk to eachother.

I'll rep you both upaa27 and InfinitusEquitas !

edit: must spread some rep before giving some to you again InfinitusEquitas

Question: Is the battery replaceable? Standard cell size or something hard to find / install?

I have wanted one of these in the past but since most of them come from over seas I figure customs might be an an issue.

The cheaper ones continuously download - also the live update options do the same. But most of the standalone ones and better quality are capable of operation without requiring a cell signal. They will use it, but it isn't necessary.

Good example is Garmin's Navigon for the iPhone. It started at over $100 as an app, but all the maps are downloadable and updated every 6 months. Option for live traffic and rerouting, and even without cell signal you're golden.

Personally I wouldn't buy one that lost you without a cell signal, I travel daily and too many places still have dead spots, even though I live in one of the largest cities in the U.S.

But I do like the rerouting here in Charlotte. Which BTW is larger than Atlanta, Boston, Denver, etc.

you guys are forgetting the loop holes.these jammers are not illegal.the law is illegal.
you have a right to privacy and that jammer protects fones from being hacked and folks listening in on your conversation.
your constitutional right to privacy supercedes their stupid law,that by supreme court ruling does not have to be obeyed.
otherwise how do you think big corporations protect their privacy,same way.
i think this jammer is cool and if i had the money then i would buy it in a heart beat.
plus living out on acreage.i can jam whatever i want.its my private property.basically the thing is a light bulb that puts out light in frequency we cant see.call it whatever you want,its just something bright in the emf spectrum.brighter than the lights around it.
lol.sounds alot like a laser.:yh:

 

[upaa27]

F*ck the law. I care more about the people who can get really badly hurt just from using it anywhere.

 

[icecruncher]

interesting.

However,,, using lasers in public is also illegal without proper permits.

your privacy can't encroach on the privacy of others or cause harm. - also illegal. (like an electrified man trap)
that is the spirit of the law (principle) that these are based on.

I don't think we should be giving him a hard time. Who's to say his illegal jammer is worst than illegal lasers that can blind someone. This forum has no problems selling lasers within the US. We should more concerned with the chance this sale could draw negative attention from US authorities.

@ dustmite

Could you link a model number or what this retails for?

Okay. I can't stand this kind of BS. Its RADIO WAVES. Its non-ionizing radiation. I doesn't damage DNA, and doesn't cause cancer or any of that nonsense. Standing in sunlight does more damage than a phone ever could.

And 5 watts? You step outside and the sun hits you with more watts then that. There is no comparison between a phone and a microwave. Yes they use the same frequency, but a microwave is emitting focused radio energy in the KILOWATT range into a tiny, contained box.

And even if you microwaved your hand in a microwave oven, it wouldn't cause cancer. It would just burn you.

Stop spreading bullshit.


And now onto the next thing.

This whole idea of a phone/wifi/bluetooth jammer is stupid. Who are you to decide of people have network access? You aren't in charge of anyone, and you come off sounding like a presumptuous ass thinking your justified in jamming other peoples tech.

If I caught someone jamming any of my tech I would have no issue taking said jammer and smashing it into the floor.
