The 1,000 Mile GPS Jammer

The 1,000 Mile GPS Jammer
You can buy short range personal GPS jammers for well under a hundred dollars from literally thousands of web retailers, and an outfit in China (where else?) has raised the technology ante on these nefarious gizmos.
C.T.S. Technology Co. Ltd. stands ready to sell anyone a GPS jammer that can knock out signals in a 500 to 1,000 mile range, and it's easily hooked up to a car cigarette lighter socket for juice.
This illegal gizmo has a power output of 100 watts, or four times the power of the GPS satellite transmitter and could completely overwhelm GPS signals within a radius of thousands of miles on the ground. C.T.S Technology did not post a price on this high powered jammer, but I'm sure they're ready to deal.
I stumbled across this evil toy yesterday when I did a search to see of Google is keeping its promise to no longer sell GPS jammer keyword ads.
Those ads are still blocked, but a search for GPS jammers on Google comes back with just under 1.6 million results -- quite alarming since there is no backup to the GPS system

VHF band uses 300-300MHz, and UHF band is a wide band with 300-3000MHz frequencies but as a rule microphones are not using high frequencies for their work. UHF/VHF jammer blocks only the most used parts of those bands - 140-180MHz from VHF and 450-480MHz from UHF.
As you can see, all you need to do is to make sure you have low-frequency microphone that would not be jammed by your cell phone jammer. And if someday you would need to jam both mobile phones and low-frequency band, you still can do it - just visit the source link and read more about it.

What are Cell Phone Jammers?

What are Cell Phone Jammers?
A cell phone jammer is a device that emits signals in the same frequency range that cell phones use, effectively blocking their transmissions by creating strong interference. Someone using a cell phone within the range of a jammer will lose signal, but have no way of knowing a jammer was the reason. The phone will simply indicate poor reception strength.
With the ubiquitous use of cell phones, a backlash has occurred. While some people practice cell phone etiquette, many others noisily discuss their private, professional or mundane business in public areas, forcing everyone nearby to listen. On trains, subways, buses, in the grocery market, shopping mall and café, people are aggravating fellow citizens with their non-stop chit-chat. This has caused some people to take matters into their own hands. With a cell phone jammer in purse or pocket, jabbermouths can be turned off with the flip of a switch — and they won't be able to reconnect as long as the jammer is activated unless they move far enough away from the source.
It seems a tidy solution, however, there's a problem. Cell phone jammers are illegal in most countries — except to military, law enforcement and certain governmental agencies.

In the U.S. the FCC (Federal Communications Commission) makes certain frequencies available to broadcasters for public use. When an end-user pays to use that spectrum, jamming the signal is paramount to 'property theft.' The FCC is also concerned about potential "leakage" — of jammers interfering with frequencies outside the range of cell phones, like garage door openers or medical equipment; and it's worth noting that over 100,000 emergency calls are made each day from cell phones. Anyone caught manufacturing, selling, owning, or using a jammer in the U.S. is punishable by an $11,000 fine and up to a year in prison for each offense.
But the stiff penalty hasn't stopped proliferation of the devices, perhaps because the FCC has not held anyone accountable. According to one interview with Richard Welch, associate chief of the FCC's Enforcement Bureau, no actions have been taken by the FCC because "nobody has complained." This isn't surprising considering people can't tell the difference between being jammed and simply having poor signal strength which comes and goes with the best of phones even under normal circumstances.
Cell phone jammers are available in different styles and sizes from personal hand-held models that look like cell phones themselves, to units that resemble routers with multiple antennas, to even larger briefcase-style jammers. While personal jammers create a bubble of anywhere from 30 — 100 feet (9 - 30 meters) depending on the model, more powerful devices can create "dead space" of up to a mile (1.6 km) in radius. This can be useful around a Presidential motorcade, for example, to keep terrorists from detonating a bomb from miles away or even from outside the country. By wiring a cell phone to explosives the device can be triggered by simply placing a call to the phone, as was done in May 2002 by Palestinian militants in Tel Aviv when they targeted an Israeli fuel depot by rigging one of its fuel trucks.
Law enforcement also uses cell phone jammers in hostage situations to keep the suspect isolated, and in South America, banks use the devices to prevent robbers from tipping off outside accomplices to departing customers leaving with large withdrawals.
Proprietors of many kinds of businesses would like to use cell phone jammers. Restaurant owners and theater houses are just two examples of places that regularly receive complaints from patrons over cell phone abuse. Short of providing expensive metal shielding in the construction of the buildings to block cell phone signals, (which is legal), it's understandable that placing an inexpensive device in the back office to surreptitiously block cell phone usage in the establishment might be tempting. Hospitals would also like to jam cell phones which can interfere with medical equipment. Churches, libraries, courthouses and business owners that want to boost employee productivity are all examples of potential customers of cell jamming technologies.
Personal cell phone jammers start at about $250 (U.S.D.) and are widely available online despite their illegal status in most countries. The top manufacturers reportedly sell primarily to military and law enforcement but will sell the devices to anyone with the disclaimer that it is up to the buyer to make sure the device is legal in his or her country and that the buyer assumes all legal responsibility for buying, owning, or using the device.
The cell phone industry opposes the use of jammers and many have invested money in education towards cell phone etiquette as an alternative answer to the growing problem of discourteous cell phone users.

NETWORK JAMMERS: A Disruptive Service

Alleged misuse of cellphones by  Pappu Yadav, MP, RJD in Beur Jail led the Supreme Court to permit the installation of mobile phone jammers in all jails across the country.
A division bench comprising of Justice N Santosh Hegde and Justice SB Sinha has asked mobile service providers, Bharat Sanchar Nigam (BSNL) and Reliance Infocomm to inform the court on how this facility could be installed in the central jails, to begin with, for preventing "highly influential and powerful personalities from misusing mobile phones while being lodged in jail".
This misuse has to be stopped across the country in all jails and the process could begin by installing jammers at the central jails, the bench observed.
What are Jammers?
So, what is the basic functionality of jammers? Jammers are high frequency transmitters deployed for blocking mobile signals from reaching BTS (for outgoing calls) or mobile phones (for incoming calls).
The jammers can act as a virtual transmitter and interfere with the normal working of cellphones, blocking both incoming and outgoing calls. Depending upon the functionality, jammers can block radio frequency in one particular band (GSM or CDMA) or sets of bands (GSM/CDMA/VHF/UHF).

Range of jammers varies with respect to different networks in a given location


Used mainly by military and law-enforcing agencies, deployment of jammers is considered illegal in most of the countries. The primary goal of jammers is to block cellphones in areas where they are forbidden by law, such as jails and in other places where it creates a nuisance, such as: churches, theatres, concerts halls, or conference halls.
Jammers Vs Interceptors
For jails, service providers can opt for either of two solutions-detectors or jammers; and interceptors. In the first case, radio signals are detected by putting detectors in different cells, wherever required, and when the signals are detected it jams the signals.
This helps in jamming a particular area of the jail where prisoner movement takes place rather than jamming the entire jail and affecting the entire communications system. Its cost ranges between $5,000 and $35,000.
Also, service providers can opt for interceptors that are currently in use by majority of the jails worldwide. Considered to be an intelligent device, the interceptors act as an all in one device and perform functionalities of a sensor, jammer, and recording system.
So, depending upon the conversation, one can either jam or record. The intelligent system costs are on a higher side and it is in the range of $200,000.
Deploying Jammers/Interceptors
But before deploying any of the two solutions, the service provider has to do a site survey to test the signal as is done in the case of installation of BTS. Since, jamming range is a function of signal strength received form a nearby base station and varies from one location to another. Even the jamming range varies with respect to different networks in a given location. Jamming also depends on topography of that area, thickness of the wall, reflection/absorption of signals in the given area, area to be covered, and frequencies to be jammed.
Once the survey is done, the service providers are in a better position to design an efficient system by knowing the number and positioning of the jammers. The service providers can either opt for a particular frequency band (GSM/CDMA) or can opt for a mix of VHF/UHF/CDMA/GSM/satellite phone/WI-Fi/Bluetooth/DECT. Care should also be taken to see that in case of power failure there are adequate backup facilities so that the jamming/interception systems can function even without assured power supply.
Once all these factors are taken into account, service providers can ensure that jamming/interception system is foolproof and will also help in preventing highly influential and powerful personalities from misusing mobile phones while being lodged in jail.

How Mobile Jammers Work

How Mobile Jammers Work

Cell phones use one band to send signal to the base station (upward signal) and another band to receive signal from base station (downward signal). Mobile phone can be disabled via interrupting any of these signals. Because the distance to base station is larger than the distance to mobile phone that needs to be blocked, it needs less energy to block signal from base station to phone.

How Cell Phone Jammers Work

How Cell Phone Jammers Work

­Cell phones are everywhere these days. According to the Cellular Telecommunications and Internet Association, almost 195 million people in the United States had cell-phone service in October 2005. And cell phones are even more ubiquitous in Europe.
It's great to be able to call anyone at anytime. Unfortunately, restaurants, movie theaters, concerts, shopping malls and churches all suffer from the spread of cell phones because not all cell-phone users know when to stop talking. Who hasn't seethed through one side of a conversation about an incredibly personal situation as the talker shares intimate details with his friend as well as everyone else in the area?
­While most of us just grumble and move on, some people are actually going to extremes to retaliate. Cell phones are basically handheld two-way radios. And like any radio, the signal can be disrupted, or jammed.
In this article, you'll see how cell-phone jammers work and learn about the legality of their use

Components of a jammer

Components of a jammer
Antenna
Every jamming device has an antenna to send the signal. Some are contained within an electrical cabinet. On stronger devices, antennas are external to provide longer range and may be tuned for individual frequencies.
Circuitry
The main electronic components of a jammer are:
Voltage-controlled oscillator — Generates the radio signal that will interfere with the cell phone signal
Tuning circuit — Controls the frequency at which the jammer broadcasts its signal by sending a particular voltage to the oscillator
Noise generator — Produces random electronic output in a specified frequency range to jam the cell-phone network signal (part of the tuning circuit)
RF amplification (gain stage) — Boosts the power of the radio frequency output to high enough levels to jam a signal

Power supply
Smaller jamming devices are battery operated. Some look like cellphones and use cellphone batteries. Stronger devices can be plugged into a standard outlet or wired into a vehicle's electrical system.
The jammer's effect can vary widely based on factors such as proximity to towers, indoor & outdoor settings, presence of buildings and landscape, even temperature and humidity play a role.
There are concerns that crudely designed jammers may disrupt the functioning of medical devices such as pacemakers.[citation needed]However, like cellphones, most of the devices in common use operate at low enough power output (<1W) to avoid causing any problems.

Phone Jammer Operation

Phone Jammer Operation
As with other radio jamming, cell phone jammers block cell phone use by sending out radio waves along the same frequencies that cellular phones use. This causes enough interference with the communication between cell phones and towers to render the phones unusable. On most retail phones, the network would simply appear out of range. Most cell phones use different bands to send and receive communications from towers (called frequency division duplexing, FDD). Jammers can work by either disrupting phone to tower frequencies or tower to phone frequencies. Smaller handheld models block all bands from 800MHz to 1900MHz within a 30-foot range (9 meters). Small devices tend to use the former method, while larger more expensive models may interfere directly with the tower. The radius of cell phone jammers can range from a dozen feet for pocket models to kilometers for more dedicated units. The TRJ-89 jammer can block cellular communications for a 5-mile (8 km) radius.
Less energy is required to disrupt signal from tower to mobile phone, than the signal from mobile phone to the tower (also called base station), because the base station is located at larger distance from the jammer than the mobile phone and that is why the signal from the tower is not as strong.
Older jammers sometimes were limited to working on phones using only analog or older digital mobile phone standards. Newer models such as the double and triple band jammers can block all widely used systems (CDMA, iDEN, GSM, et al.) and are even very effective against newer phones which hop to different frequencies and systems when interfered with. As the dominant network technology and frequencies used for mobile phones vary worldwide, some work only in specific regions such as Europe or North America.

Phone Jammer History

Phone Jammer History
The rapid proliferation of cell phones at the beginning of the 21st century to near ubiquitous status eventually raised problems such as their potential use to invade privacy or contribute to rampant and egregious academic cheating. In addition public backlash was growing against the intrusive disruption cell phones introduced in daily life. While older analog cell phones often suffered from chronically poor reception and could even be disconnected by simple interference such as high frequency noise, increasingly sophisticated digital phones have led to more elaborate counters. Cell phone jamming devices are an alternative to more expensive measures against cell phones, such as Faraday cages, which are mostly suitable as built in protection for structures. They were originally developed for law enforcement and the military to interrupt communications by criminals and terrorists. Some were also designed to foil the use of certain remotely detonated explosives. The civilian applications were apparent, so over time many companies originally contracted to design jammers for government use switched over to sell these devices to private entities. Since then, there has been a slow but steady increase in their purchase and use, especially in major metropolitan areas.

What are jammers

Mobile phone jammer

A mobile phone jammer is an instrument used to prevent cellular phones from receiving signals from base stations. When used, the jammer effectively disables cellular phones. These devices can be used in practically any location, but are found primarily in places where a phone call would be particularly disruptive because silence is expected.
