A cell phone jammer is an instrument used to prevent cellular phones from receiving signals from or transmitting signals to base stations. When used, the jammer effectively disables cellular phones. These devices can be used in practically any location, but are found primarily in locales where a phone call would be particularly disruptive. These include places of worship (churches, mosques, etc.), libraries, cinemas, meeting rooms, and other places where silence is expected.

History
The rapid proliferation of cell phones in recent years to near ubiquitous status eventually raised problems such as their potential use to invade privacy, contribute to academic cheating, or even aid in industrial espionage. In addition public backlash was growing against the perceived 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 as been a slow but steady increase in their purchase and use especially in major metropolitan areas.


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 of cell phones and the 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. Thus 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. 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. [1]

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 (AMPS, 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.

The power of the jammer's effect can vary widely based on factors such as proximity to towers, indoor and 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. However, like cell phones, most of the devices in common use operate at low enough power output (<1W) to avoid causing any problems.

With the rising popularity of commercial MMORPG games came the desire from ardent players of these games to run their own servers beside the ones run by the game's creator. Since the original server software is not usually available, the behavior of the server has to be re-engineered. This can be done by analyzing the data stream with the original server, or by disassembling and analyzing the client which is available.

Ultima Online was one of the first large MMORPGs. Due to its openness in implementation, server emulators arose very quickly, even during the beta stage of development. The destination to which the client connects was changeable by simply editing a text file. In beta stage the client-server data stream was not encrypted yet. The term server emulator became known through Ultima Online server reimplementation such as UOX, which was the pioneer. Many forks and reimplementations followed UOX, because its source code was released under the GNU General Public License relatively early. RunUO is today the most widely used UO-server emulator. After RuneScape implemented anti-cheating measures, many gamers left and started their own private servers. The best place to discuss the private server is at Trik- The Master of Private Server.
