PostSubject: Most Important Information About Mobile Phone's   Most Important Information About Mobile Phone's EmptyMon Jun 09, 2008 4:24 am

The mobile Most Important Information About Mobile Phone's Emoticon-0161-phone (also called a mobile, wireless, cellular Most Important Information About Mobile Phone's Emoticon-0161-phone, cell Most Important Information About Mobile Phone's Emoticon-0161-phone, or hand Most Important Information About Mobile Phone's Emoticon-0161-phone(hp))[1] is a short-range, portable electronic device used for mobile voice or data communication over a network of specialized base stations known as cell sites. The first commercial mobile Most Important Information About Mobile Phone's Emoticon-0161-phone service was launched in Japan by NTT in 1979, and by November 2007, the total number of mobile Most Important Information About Mobile Phone's Emoticon-0161-phone subscriptions in the world had reached 3.3 billion, or half of the human population (although some users have multiple subscriptions, or inactive subscriptions), which also makes the mobile Most Important Information About Mobile Phone's Emoticon-0161-phone the most widely spread technology and the most common gadget in the world.[2] In addition to the standard voice function of a teleMost Important Information About Mobile Phone's Emoticon-0161-phone, current mobile Most Important Information About Mobile Phone's Emoticon-0161-phones may support many additional services, and accessories, such as SMS for text messaging, email, packet switching for access to the Internet, gaming, bluetooth, infrared, camera with video recorder and MMS for sending and receiving photos and video. Most current mobile Most Important Information About Mobile Phone's Emoticon-0161-phones connect to a cellular network of base stations (cell sites), which is in turn interconnected to the public switched teleMost Important Information About Mobile Phone's Emoticon-0161-phone network (PSTN) (the exception is satellite Most Important Information About Mobile Phone's Emoticon-0161-phones). The first mobile Most Important Information About Mobile Phone's Emoticon-0161-phone to enable internet connectivity and wireless email use, was the Nokia Communicator released in 1996 and created a new category of expensive Most Important Information About Mobile Phone's Emoticon-0161-phones called smartMost Important Information About Mobile Phone's Emoticon-0161-phones. In 1999 the first mobile internet service was launched by NTT DoCoMo in Japan under the i-Mode service. By 2007 over 798 million people around the world accessed the internet or equivalent mobile internet services such as WAP and i-Mode at least occasionally using a mobile Most Important Information About Mobile Phone's Emoticon-0161-phone rather than a personal computer.

Most Important Information About Mobile Phone's Empty

--Cellular systems--

Mobile Most Important Information About Mobile Phone's Emoticon-0161-phones send and receive radio signals with any number of cell site base stations fitted with microwave antennas. These sites are usually mounted on a tower, pole or building, located throughout populated areas, then connected to a cabled communication network and switching system. The Most Important Information About Mobile Phone's Emoticon-0161-phones have a low-power transceiver that transmits voice and data to the nearest cell sites, normally not more than 8 to 13 km (approximately 5 to 8 miles) away.

When the mobile Most Important Information About Mobile Phone's Emoticon-0161-phone or data device is turned on, it registers with the mobile teleMost Important Information About Mobile Phone's Emoticon-0161-phone exchange, or switch, with its unique identifiers, and will then be alerted by the mobile switch when there is an incoming teleMost Important Information About Mobile Phone's Emoticon-0161-phone call. The handset constantly listens for the strongest signal being received from the surrounding base stations. As the user moves around the network, the mobile device will "handoff" to various cell sites during calls, or while waiting (idle) between calls it will reselect cell sites.

Cell sites have relatively low-power (often only one or two watts) radio transmitters which broadcast their presence and relay communications between the mobile handsets and the switch. The switch in turn connects the call to another subscriber of the same wireless service provider or to the public teleMost Important Information About Mobile Phone's Emoticon-0161-phone network, which includes the networks of other wireless carriers. Many of these sites are camouflaged to blend with existing environments, particularly in scenic areas.

The dialogue between the handset and the cell site is a stream of digital data that includes digitized audio (except for the first generation analog networks). The technology that achieves this depends on the system which the mobile Most Important Information About Mobile Phone's Emoticon-0161-phone operator has adopted. The technologies are grouped by generation. The first-generation systems started in 1979 with Japan, are all analog and include AMPS and NMT. Second-generation systems, started in 1991 in Finland, are all digital and include GSM, CDMA and TDMA.

The nature of cellular technology renders many Most Important Information About Mobile Phone's Emoticon-0161-phones vulnerable to 'cloning': anytime a cell Most Important Information About Mobile Phone's Emoticon-0161-phone moves out of coverage (for example, in a road tunnel), when the signal is re-established, the Most Important Information About Mobile Phone's Emoticon-0161-phone will send out a 're-connect' signal to the nearest cell-tower, identifying itself and signalling that it is again ready to transmit. WIth the proper equipment, it's possible to intercept the re-connect signal and encode the data it contains into a 'blank' Most Important Information About Mobile Phone's Emoticon-0161-phone -- in all respects, the 'blank' is then an exact duplicate of the real Most Important Information About Mobile Phone's Emoticon-0161-phone and any calls made on the 'clone' will be charged to the original account.

Third-generation (3G) networks, which are still being deployed, began in Japan in 2001. They are all digital, and offer high-speed data access in addition to voice services and include W-CDMA (known also as UMTS), and CDMA2000 EV-DO. China will launch a third generation technology on the TD-SCDMA standard. Operators use a mix of predesignated frequency bands determined by the network requirements and local regulations.

In an effort to limit the potential harm from having a transmitter close to the user's body, the first fixed/mobile cellular Most Important Information About Mobile Phone's Emoticon-0161-phones that had a separate transmitter, vehicle-mounted antenna, and handset (known as car Most Important Information About Mobile Phone's Emoticon-0161-phones and bag Most Important Information About Mobile Phone's Emoticon-0161-phones) were limited to a maximum 3 watts Effective Radiated Power. Modern handheld cellMost Important Information About Mobile Phone's Emoticon-0161-phones which must have the transmission antenna held inches from the user's skull are limited to a maximum transmission power of 0.6 watts ERP. Regardless of the potential biological effects, the reduced transmission range of modern handheld Most Important Information About Mobile Phone's Emoticon-0161-phones limits their usefulness in rural locations as compared to car/bag Most Important Information About Mobile Phone's Emoticon-0161-phones, and handhelds require that cell towers be spaced much closer together to compensate for their lack of transmission power.

Some handhelds include an optional auxiliary antenna port on the back of the Most Important Information About Mobile Phone's Emoticon-0161-phone, which allows it to be connected to a large external antenna and a 3 watt cellular booster. Alternately in fringe-reception areas, a cellular repeater may be used, which uses a long distance high-gain dish antenna or yagi antenna to communicate with a cell tower far outside of normal range, and a repeater to rebroadcast on a small short-range local antenna that allows any cellMost Important Information About Mobile Phone's Emoticon-0161-phone within a few meters to function properly

---Media---

The mobile Most Important Information About Mobile Phone's Emoticon-0161-phone became a mass media channel in 1998 when the first ringing tones were sold to mobile Most Important Information About Mobile Phone's Emoticon-0161-phones by Radiolinja in Finland. Soon other media content appeared such as news, videogames, jokes, horoscopes, TV content and advertising. In 2006 the total value of mobile Most Important Information About Mobile Phone's Emoticon-0161-phone paid media content exceeded internet paid media content and was worth 31 Billion dollars (source Informa 2007). The value of music on Most Important Information About Mobile Phone's Emoticon-0161-phones was worth 9.3 Billion dollars in 2007 and gaming was worth over 5 billion dollars in 2007 (source Netsize Guide 2008).

The mobile Most Important Information About Mobile Phone's Emoticon-0161-phone is often called the Fourth Screen (if counting cinema, TV and PC screens as the first three) or Third Screen (counting only TV and PC screens). It is also called the Seventh of the Mass Media (with Print, Recordings, Cinema, Radio, TV and Internet the first six). Most early content for mobile tended to be copies of legacy media, such as the banner advertisement or the TV news highlight video clip.

---Power supply---

Mobile Most Important Information About Mobile Phone's Emoticon-0161-phones generally obtain power from batteries which can be recharged from a USB port or from mains power or a cigarette lighter socket in a car using an adapter (often called battery charger or wall wart). Formerly, the most common form of mobile Most Important Information About Mobile Phone's Emoticon-0161-phone batteries were nickel metal-hydride, as they have a low size and weight. Lithium-Ion batteries are sometimes used, as they are lighter and do not have the voltage depression that nickel metal-hydride batteries do. Many mobile Most Important Information About Mobile Phone's Emoticon-0161-phone manufacturers have now switched to using lithium-Polymer batteries as opposed to the older Lithium-Ion, the main advantages of this being even lower weight and the possibility to make the battery a shape other than strict cuboid. Mobile Most Important Information About Mobile Phone's Emoticon-0161-phone manufacturers have been experimenting with alternate power sources, including solar cells.

In addition to the battery, most cellMost Important Information About Mobile Phone's Emoticon-0161-phones require a small microchip, called a Subscriber Identity Module or SIM Card, to function. Approximately the size of a one-cent postage stamp, the SIM Card is installed underneath the battery in the rear of the unit, and (when properly activated) stores the Most Important Information About Mobile Phone's Emoticon-0161-phone's configuration data, and information about the Most Important Information About Mobile Phone's Emoticon-0161-phone itself, such as which calling plan the subscriber is using. When the subscriber removes the SIM Card, it can be re-inserted into another Most Important Information About Mobile Phone's Emoticon-0161-phone and used as normal.

Each SIM Card is activated by use of a unique numerical identifier; once activated, the identifier is locked down and the card is permanently locked in to the activating network. For this reason, most retailers will refuse the return of an activated SIM Card.

Those cell Most Important Information About Mobile Phone's Emoticon-0161-phones that do not use a SIM Card have the data programmed in to their memory. This data is accessed by using a special digit sequence to access the "NAM" as in "Name" or number programming menu. From here, one can add information such as a new number for your Most Important Information About Mobile Phone's Emoticon-0161-phone, new Service Provider numbers, new emergency numbers, change their Authentication Key or A-Key code, and update their Preferred Roaming List or PRL. However, to prevent the average Joe from totally disabling their Most Important Information About Mobile Phone's Emoticon-0161-phone or removing it from the network, the Service Provider puts a lock on this data called a Master Subsidiary Lock or MSL.

The MSL also ensures that the Service Provider gets payment for the Most Important Information About Mobile Phone's Emoticon-0161-phone that was purchased or "leased". For example, the Motorola Razr V9C costs upwards of CAD $500. You can get one from Bell Mobility for approximately $200. The difference is paid by the customer in the form of a monthly bill. If, in this case, Bell Mobility did not use a MSL, then they may lose the $300–$400 difference that is paid in the monthly bill, since some customers would cancel their service and take the Most Important Information About Mobile Phone's Emoticon-0161-phone to another carrier such as Telus, or Verizon. This would eventually put the carrier or in this case, Bell Mobility out of business.
