Sick of ringing cell phones?

Sick of ringing cell phones? Then cheaply and effectively jam the signals with a device like the Wave-Shield pocket jammer. They're illegal in the U.S., but that's not stopping some people.
Just build yourself a portable jammer! I recall seeing reasonably simple schematics somewhere online -- the device wasn't very sophisticated; it just shot high-powered interference across multiple phone bands.

I don't see how a scanner will be useful for listening to cell phone calls, since they're all digital now anyway, and compressed and encrypted and shit.

cellphonescanner.com managed to stream quite a bit of analog content from Ottawa. The site seems to be gone now though.

forget worrying about cingulare customers in the bay area. their services are so over-subscribed that you can never get through... my phone hardly ever rings. i get a beep an hour later notifying me that a message was left.

What if the jammer blocked out a phone call from the hospital to the mother of a kid who was just in a serious car crash? I fail to see how cell phone conversations are different from any normal conversation, especially when the ringer is turned to vibrate instead of an audible ring. Would you tell Joe Q. Public on the subway to shut up when he was talking with his wife or business counterpart? Then why force his cell phone down?
I understand that some (very few) people will use cell phones in places such as movie theatres and churches where they could be considered inappropriate (although I can't see why a restaurant would qualify). However, manners can't be forced.

O wow, you've so inspired me! I'm plagued by these jackasses who, in their little-penismobiles equipped with the 500-watt stereo system blaring at seizure inducing volumes, have this bizarre knack for parking outside my bedroom window in the wee hours of the night (I live in an apartment building). While I wouldn't want to do permanent damage, it would be so wonderful if a device existed that would temporarily jam such stereo equipment from say 50ft., and which could be bought or built from plans online.

Seriously though: there's no excuse for people to be rude and obtrusive with their cell phones... but I hardly see how that grants you the "right" to be a rude and obstrusive jammer right back.

[The preceding message was brought to you by the National Rifle and Cell Phone Association.]
All people who use cell phones in certain places -- pubs, restaurants, theaters, anywhere within 50 feet of me, etc. -- are rude. Jam them in those places. Notify potential customers at the door that people who need constant access to their phones should not come in. There are many restaurants that welcome rude people; encourage phoners to go to them. Many otherwise phone-bound people would pay extra to go somewhere guaranteed devoid of ringing phones for an hour or two.

Its only a matter time before opposite sound devices are affordable (mic picks up sound and speaker pushes out opposite waves canceling out both sounds) are perfected
This only works in a very, very limited way -- the physics of sound make it impossible except for very specific applications. (For example, noise-canceling headsets.)

It's NOT the cell phones. I carry my cell phone everywhere I go. When I go into a theatre or even into a restuarant, I turn my ringer on vibrate.
Don't punish ME because other people are idiots.
There are people who are bound to their cell phones--doctors come to mind but certainly parenting is much less stressful when you have a cell phone. A jammer would inconvenience even the responsible people.
Again, these are technological advances which ease people's lives. It's the idiots out there who reduce the gains.
One other thing, with the exception of drivers (because I have doubts about that) I think more people are responsible (and not rude) than not. It's just that you NOTICE the ones who are rude.

Someone needs to start a pub and restaurant chain with shielding (always legal) built in. Guarantee that phones won't work there, that there will never be a video game or television in there, and that the only music there will be live and unamplified. If fire and health codes permit it, install gaslight. Try hard to eliminate all circuitry, even all electricity, from the place. Maybe choose a year -- 1850? 1875? 1900? -- and aim to have nothing there that wouldn't be in the average pub and restaurant of that year.
People would be willing to pay enormous sums for the pleasure.

Then it looks like you've got a business plan, no?
As fooljay said, it's not the cell phones, it's the stupid asses who leave their ringers on instead of turning them to vibrate, or proceed to take phone calls during dinner or movies. It's not my fault, so why penalize me for having better manners than some?
And while you're at it, why not ban all small children from public places? Some of them make more noise than a cell phone ringer or user ever would, are likely to trip you or grab at your legs, and in some cases they even smell bad. Eh.

I wouldn't be against banning kids from some public places. A restaurant, for example, should be able to declare itself kid-free.
Some places decide who can come in based on what people wear. No tie? Stay out. But kids are much more annoying than men without ties. [Though nothing is more annoying than Men Without Hats. Especially the goofy chick.]

Obviously, the solution would be to intermittently jam the conversations of people who were unbearably rude. It's important that you only jam the call briefly, so that they call back. And then you can jam it again. Read some B.F. Skinner for more on this. Or any biography of Steve Wozniak.
From the article: It's apparently not illegal to build a shielded room and jam calls that way.

Can any of you oh-so-bothered people explain why it is so very troublesome to you that someone several tables away has a cell phone conversation in a restaurant? Is it that the two or three chirps are so startling and awful? Is it that you can't bear to see people conversing with other people that you can't also see? What is it? I'm dying to know.

I think the legitimate objections include: (1) phones ringing at inappropriate times (2) a shrill and/or tacky ring at inappropriate times; (3) people talking at louder than normal speech amplitude; and (4) more conversation/sound going on than what would take place without cell phones. On this last point, what comes to mind is the commuter train. The expectation is that a commuter train (or an AMTRAK trip) will include a certain amount of people, fairly few, conversing with other people on the train. Cell phones change this. There is more talk going on, more sound, and as a result, the ambient sound level gets signifantly higher. I have other objects as well (e.g., the personal or other nature of the conversation; the fact that the conversation, while nearby, doesn't include you; the aesthetic horror of, e.g., cell phones in a concert hall), but these are the chief ones; the ones which have made me move my place in a train, or feel like punching people.

I asked rather specifically about restaurants, but let's use your commuter train example, ParisParamus.
1. Phones ringing at inappropriate times -- what is an inappropriate time on a train? When announcements are made, maybe, but other than that, is there some silence rule that I'm unaware of?
2. Shrill or tacky rings at inappropriate times -- tastes differ. What's shrill to you may be just right for me to hear from the depths of my baggage. Tacky? Same difference - I may hate the William Tell Overture ringtones, but love my Animaniacs Theme Song. It's not a legitimate reason to oppose the use of the technology wholesale.
3. People talking at louder than normal speech amplitude -- it happens, whether they're talking on the phone, reprimanding a squalling kid, explaining something in detail to an elderly companion, hard of hearing themselves, etc. Unless they're screaming for a protracted period of time or disturbing you intentionally, it's still not enough to oppose the use of phones in all public places.
4. More conversation/sound going on than would take place without cell phones -- what? More appropriately, so what? If you're not in a library or in a place where there is something specific to hear, like a movie or a concert, what difference does it make if everyone around you is talking, whether on a phone or to a companion? If you need that much peace and quiet maybe you should stay home. Ambient noise happens.
Maybe you should stop being so nosey and try concentrating on your own interests. Then other people's conversations won't be so bothersome.

This point was not directed specifically to trains, although traveling at 9pm or 10pm on AMTRAK and trying to nap, or taking the 10pm train home from the City might make levels of sound especially "inappropriate." Does the term LOUT mean anything to you? Inappropriate also includes during films, concerts, religious services, depositions, motions, therapy sessions.
Shrill or tacky rings at inappropriate times -- tastes differ.
Sorry, but I claim a public right to no more than a certain amount of noise, especially shrill noise, especially in confined spaces. When 10 or 20 cell phones go off in the course of a 50 minute train ride, that's unacceptably painful (even without the ensuing phone conversations).
it happens, whether they're talking on the phone, reprimanding a squalling kid, explaining something in detail to an elderly companion, hard of hearing themselves, etc.
None of the other things happen anywhere as frequently as obnoxious cell phone conversation.

My remarks were addressed to all such places, including trains. Why are radios illegal on trains? On planes?
Sorry I am more sensitive to noise than you.

That's not justification for the banning of cell phones from any of the public places that you've mentioned. Religious services, movies and similar entertainment and private meetings are another issue -- in those situations, neither noise nor interruptions are appropriate. The remainder of the scenarios you paint, however, have no such limitations. They are public access situations where whatever normal-volume noise (and cell phone ringtones count among that) is par for the course.
I strongly recommend a hearty dose of getting over it.

Cell phones are legal, but annoying, on trains. The problem is reception in tunnels. Transit providers use different service providers so your AT&T phone might not work in a train tunnel while Verizon will. In Europe, with the GSM standard, that's not an issue.
