Cell phone (telefone celular) is a wireless, portable, long-range, electronic telephone, And also this during travel can seamlessly change antenna connections, from radio reception cell to Yet another radio reception cell, with no dropping or losing the ongoing call.

Besides the standard voice function of a telephone, latest cell phones (telefone celular) have features including SMS for text messages, MMS for multimedia messages, radio, games, Web connectivity for email, browsing, blogging, music (MP3) playback, memo recording, built in cameras and camcorders, ringtones, personal organizers, Push-to-Talk (PTT), Bluetooth and infrared connectivity, call registers, streaming video, downloading video, video call, and too serve as wireless modems for PCs that can be connected to the Internet.

The power in a cell phone (telefone celular) is obtained from rechargeable batteries, Which might be recharged from one the mains, a USB port or a cigarette lighter port in an automobile. Nickel Metal Hydride were the most Well-liked types of batteries, And this as a result of the "memory effect" (the user can recharge only when the whole battery is drained off) were replaced by Lithium-Ion batteries, And this did not suffer in one any memory effect.

Cell phones (telefone celular) came into existence simply because of the invention of hexagonal cells in 1947, for the base stations by Bell Labs engineers at AT&T. This was further developed through the 1960s by Bell Labs. During a call, the channel frequency could not be changed automatically from cell (base station coverage area) to An additional cell (base station coverage area) as the person traveled from one the region of one cell in to the region of An additional cell. Amos Joel of Bell Labs invented a breakthrough invention and called it as the `call handoff` by And this the channel frequency would be changed automatically from one cell to Yet another cell, during the same call, as the mobile user traveled in one cell to Yet another cell. due to their heavy construction, these to were utilized mainly in automobiles.

The initial practical cell phone in a non-vehicle setting, and And also this could be handheld, was invented by Martin Cooper, the General Manager (Communications Division) of Motorola, who made the world`s initial handheld cell phone (telefone celular) call on April 3, 1973.

The technology by And also this the cell phone (telefone celular) works depends upon the mobile phone operator; however, every one of them use electromagnetic radio waves, which are in touch using a cell site (base station). The base station is composed of multiple antennas which are mounted on a pole, tower, or building. Cell sites seem to be spread at a distance of 5 to 8 miles (approx. 8 to 13 km) from one each other. The low power transceiver from the cell phone transmits the voice and data to the nearest cell site. During movement, the cell phone will "handoff" the Information to other cell site. Mobile phone operators use multiple technologies to keep the smooth stream of digitized data in one the cell phone into the cell site and vice versa.

The wireless telephone technologies seem to be grouped under heads known as generations, starting from one zero generation or 0G. The current generation going on is 4G; however, there appear to be old cell phones (telefone celular) that still operate on 1G, 2G, and 3G technologies. The wireless telephone technologies utilized in every generation seem to be as given below:

0G: PTT, MTS, IMTS, AMTS, OLT, MTD, Autotel/PALM, ARP
1G: NMT, AMPS/TACS/ETACS, Hicap, CDPD, Mobitex, DataTac
2G: GSM, iDEN, D-AMPS, IS-95/cdmaOne, PDC, CSD, PHS, GPRS, HSCSD, WiDEN, CDMA2000 1xRTT/IS-2000, EDGE (EGPRS)
3G: W-CDMA, UMTS (3GSM), FOMA, TD-CDMA/UMTS-TDD, 1xEV-DO/IS-856, TD-SCDMA, GAN (UMA), HSPA, HSDPA, HSUPA, HSPA+, HSOPA
4G : UMB, UMTS Revision 8 (LTE), WiMAX
Frequency bands: SMR, Cellular, PCS

The impact of cell phone (telefone celular) usage on human health has been of considerable worldwide concern. analysis studies in Copenhagen, from the Danish Institute of Cancer Epidemiology, the National Cancer Institute, as well as the Institute of Cancer Research, do not establish any link between cancer and cell phone usage. However, an intergovernmental agency IARC (International Agency for analysis on Cancer) forming part of the World Health enterprise of the United Nations, undertook a analysis of 4,500 users and found a statistically significant link between cell phone usage and tumor frequency. Further study is going on.

Cell phone (telefone celular) usage and driving is truly a Well-known worldwide phenomenon. Some jurisdictions have banned usage of hand-held phones during driving, but allowed the hands-free fashion of cell phone usage while driving. However, studies have discovered out that the distraction is triggered by the conversation itself; hence, both hand-held and hands-free cell phones contribute towards road traffic accidents. Further studies on cell phone usage and driving are going on.

Nokia Corporation is currently the world`s largest brand name of cell phones (telefone celular). Other notable cell phone manufacturers, in alphabetical order, appear to be 3G, Audiovox (now UT Starcom), Benefon, BenQ-Siemens, Fujitsu, High Tech Computer Corporation (HTC), Kyocera, LG Mobile, Motorola, NEC, Panasonic (Matsushita Electric), Pantech Curitel, Philips, investigation In Motion, Sagem, Samsung, Sanyo, Sharp, Siemens, Sierra Wireless, SK Teletech, Sony Ericsson, T&A Alcatel, Toshiba, and Verizon.
