A mobile phone also known as a wireless phone, cell phone, or cellular telephone is a long-range, electronic device used for mobile voice or data communication over a network of specialised base stations known as cell sites. In addition to the standard voice function of a mobile phone, telephone, current mobile 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 phones connect to a cellular network of base station (cell sites), which is in turn interconnected to the public switched telephone network (PSTN) (the exception is satellite phones).
According to internal memos, Americal Telephone & Telegraph discussed developing a wireless phone in 1915, but were afraid deployment of the technology could undermine its monopoly on wired service in the U.S.
Mobile 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 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 phone or data device is turned on, it registers with the mobile telephone exchange, or switch, with its unique identifiers, and can then be alerted by the mobile switch when there is an incoming telephone call. The handset constantly listens for the strongest signal being received from the surrounding base stations, and is able to switch seamlessly between sites. As the user moves around the network, the "handoffs" are performed to allow the device to switch sites without interrupting the call.

Nokia cell phones are good recognized all over the world due to their heavy-duty design shape and advance cellular technologies. Nokia has introduced many cellular devices; lately they have launched Nokia N-Series cell phones such as; Nokia N70 cell phone, Nokia N80 mobile phone, Nokia N93 cell phones and economical Nokia N95. Additionally, all Nokia phones have essential cellular features and provide good call class.
Nokia had been producing commercial and military mobile radio communications technology since the 1960s. Since 1964 Nokia had developed VHF-radio simultaneously with Salora Oy, which later in 1971 also developed the ARP-phone. In 1979 the merger of these two companies resulted in the establishment of Mobira Oy. Mobira began developing mobile phones for the Nordic Mobile Telephony (NMT) network standard that went online in the 1980s and in 1982 it introduced its first car phone, the Mobira Senator for NMT 450 networks.
The successor organization to Nokia's Customer and Market Operations division, represents the sales, marketing and manufacturing functions of the company, led by Anssi Vanjoki.

er in the world after Nokia, Motoroal and Samsung. The sales of products largely increased due to the launch of the Walkman series. While Sony Ericsson has been enjoying strong growth recently, its South Korean rival LG Electronics overtook it in 2008 due to the company's profits falling significantly by 43% to €133 million (approx. US$ 193.6746 million), sales falling by 8% and market share dropping from 9.4% to 7.9%, despite favourable conditions that the handset market is expected to grow by 10% in 2008. Sony Ericsson announced another profit warning in June 2008 and saw net profit crash by 97% in Q2 2008, announcing that it would cut 2,000 jobs, leading to wide fear that Sony Ericsson is on the verge of decline along with its struggling rival, Motorola. In the profits were much on the same level, however November and December saw increased profits along with new models being released such as the C905 being one of the top sellers across the United Kingdom.
Sony Ericsson has, as of July 18, 2008, approximately 9,400 employees and 2,500 contractors worldwide. Hideki Komiyama is the president of the company and has been since November 1, 2007 when he replaced Miles Flint. The Corporate Executive Vice President is Anders Runevad. As of November 2008 SonyEricsson getting much better.

Samsung Cell Phones Samsung Telecommunications is one of five business units with
in Samsung Electronics, belonging to the Samsung Group, and consists of the Mobile Communications Division, Telecommunication Systems Division, Computer Division, MP3 Business Team, Mobile Solution Centre and Telecommunication R&D Centre. Telecommunication Business produces a full spectrum of products from mobiles and other mobile devices such as MP3 players and laptop computers to telecommunication network infrastructure. Headquarters is located in Suwon, Korea.Samsung is well recognizable brand in electronic products due to their latest technologies and trustworthy design structures. In cell phone industry Samsung also has good status. Th
e famous Samsung ce
ll phones are Samsung D830 mobile phones, Samsung E909 cell phones and Samsung A707 cell phones.Samsung developed its first CDMA mobile phone in March 1996, to coincide with the launch of CDMA service. The first digital handset, the SCH-100, was extra light and slim, and enabled clear voice communication. Before long, Samsung became the leader in the PCS market.
Samsung made its first foray into the global market in 1996, when it exported its PCS phones to Sprint, an American CDMA carrier. Sprint signed $600 million contract with Samsung, under which Samsung would provide its PCS phones to Sprint for three years under the co-branded name "Sprint-Samsung." After this Samsung expanded into Hong Kong (Huchinson, CDMA) in 1997, and Brazil (TELESP and TELERJ, CDMA) in 1998. After successfully exporting to Brazil, Samsung built a mobile phone production facility in Brazil in 1998, in the hopes of expanding into Latin America.
In 1999, Samsung secured the number one position in the worldwide CDMA market where it accounted for more than 50% of market share. However, the worldwide CDMA market was far smaller than the GSM market, which accounted for 70% of the total worldwide mobile communications market. Moreover, the domestic market was approaching saturation, and competition was becoming more intense.
Thus, to achieve further growth, Samsung had to penetrate the GSM market.
