MOBILE PHONE manufacturers are now devoting at least a page in the user's manual on cell phone etiquette. While instructions are written mostly in Korean and Japanese, an English or Hindi script is an integral part of such handouts in India - one of the world's leading mobile market.

To us however, it hardly makes any difference whether or not the user manual is written in a language intelligible to us, who reads it after all?

One of the instructions underlines the usage of a phone, that it should be switched off while in sensitive areas, like petrol pumps, ATM kiosks, the court and police stations, hospitals and other places as prescribed by the local government.

"It's quite bizarre an instrument born out of the need to 'stay connected' is now being perceived as something we should rather stay away from. To me, calls bring in contracts. I cannot imagine switching off my phone for a minute," says a  businessman.

His story is not uncommon; there are many who huff at what they call, an infringement of their rights. But what about others right to some peace?

Mobile phones are in the hands of more than a million people today who've affected a change in the rules of all public functions. Earlier such programmes would begin with a prayer - now they make a start with a plea, Please, switch off your mobile phones.

Because none is bothered, and there's a polyphonic tone to be held responsible for breaking the blissful silence in a place where it should not - during an important speech, in a theatre, a church or hospital - cell phone jammers have come into the picture.

Just as a diamond is used to cut another, technology counters itself. The physics of a cell `jammer' is quite simple; it emits low-level radio frequencies that avert mobile signals with a preset radius, making a cell out of network reach for the cell user.

Silence please

In Hyderabad, phone jammers are reported to have been installed in the Assembly and the airport. While in the Assembly, due to complaints by persistent MLAs of cutting off their right to be in touch with the constituency, the use of the phone jammer has been annulled but for few occasions.

The airport however needs it as use of a single mobile phone can interfere with the electronic equipment in place, and at times, result in a major disaster.

In the court, the use of a cell phone is prohibited, as it may be an obstruction in court proceedings. Stubborn folks who are not careful are taught a lesson by a fine.

"There have been cases where the phone was seized and later auctioned to someone else, because the owner of the phone refused to pay up after his polyphonic din disturbed a court in session," says criminal court advocate, K.S. Rahul. "Rules of fine levied on offenders are the same in the High Court as well as other trial courts."

With the call centre boom, the number of offices going in for cell phone jammers has gone up considerably as use of a phone in such an environment can cause disturbance while attending calls from global clients.

Superintendent of Police (C.I.D), C.V. Anand says, "Cell phone jammers are expensive instruments, everyone may not be interested to invest in them. But in politically sensitive places, they are a necessity." The former chief minister Chandrababu Naidu had a mobile phone jammer installed in one of the fleet of vehicles he used for movement within the city.

"I used to trail him at the end of the convoy, even my phone would not receive signals," observes Anand. Actually no mobile phone would work within a radius of at least 10-metres when his convoy passed by.

Does it ring a bell that after drugs and alcohol, it is the `ungodly' mobile phone that is abused most of all.


Mind it

• Put your phone on vibrate alert or turn it off in movie theatres, religious places, and social gatherings. Everyone has a right to some peace and concentration.
• Let your voicemail register your calls when you're in meetings, courtrooms, theatres, and restaurants.
• If you must talk when you are with a group of people, excuse yourself and find a secluded area.
• Keep the voice low and conversation short, if you have to speak when with a group, or in a public place.
• Don't display anger or give away your personal details or state of mind when talking on the phone in public places.
• Don't interrupt personal face-to-face conversations with friends and colleagues by answering your cell phone, SMSing or checking voice mail at that precise moment.
• Don't talk on the phone while riding or driving. You could kill yourself and others.

Around the world


Private use of mobile phone blockers is illegal in the United States and most Western countries, including Australia.

In Italy, universities started using phone jammers after discovering that teenagers were cheating on exams by sending text messages or taking pictures of tests.

Mexico's churches have jammed mobiles in their premises. The jammers, apparently the size of paperbacks, have been tucked unobtrusively among paintings of the Madonna and statues of the saints.

In Mexico, the other takers for phone jammers have been banks looking to stop robbers from communicating with their accomplices, if there is a hold-up.

Japan allows public places such as theatres and concert halls to install cell phone jammers, provided they obtain a government-issued license. In Tokyo, commuters supposedly buy mobile signal jammers to shut up chatty train passengers, even though their use is illegal.

France's industry minister approved a decision to let cinemas, concert halls and theatres install phone jammers as long as emergency calls could still be made.

While a similar move was made in Canada, Industry Canada, which regulates the country's telecommunications, decided against it, saying phone jammers could infringe on personal freedom and affect public safety by crippling communication with law enforcement and security agencies.
