Cellular Phones

From a technical viewpoint, cellular phones may be considered a form of radio, only more complicated than the usual kinds. It was Alexander Graham Bell who invented the telephone in 1876, while wireless communication could be traced to the radio's invention. The fusion of these two technologies gave us what we call cellular phones, which are now among the widely used gadgets.

CELLULAR PHONES DEFINED

Cellular phones may be analog or the digital kind, where wireless connection is used between a handset and a transmitter. This transmitter's coverage is called the "cell." As users of cellular phones move from one area (or cell) to another, the phone coverage is carried on by the local cell transmitters. Despite this, cellular phones should not be mistaken for cordless phones, which feature short wireless links to local systems. Cordless phone have limited use on shorter distances as compared to the wide coverage of cellular phones.

To fully define what cellular phones are all about, the SIM card has to be defined as well. The SIM, or subscriber identity module, is just a tiny circuit board inserted within the cellular phones. The SIM card holds the subscriber details, security data, and other information. For all intents and purposes, the SIM cards serve as the brain of cellular phones.

BENEFITS AND USES OF CELLULAR PHONES

Nowadays, cellular phones give an amazing set of functions and advantages to the user, as new features are continuously developed. Naturally, differing models give varied features. But typically, most cellular phones offer the following: storage of contact numbers, setting of reminders, built in cameras and calculators, email sending, games playing, video conferencing, TV watching, and text messaging. Modern cellular phones also allow for the integration of MP3s and PDAs.

Cellular phones are wells of data/information. Through WAP or mobile Internet, users could gather news (local and foreign) from their cellular phones. Games on cellular phones have become very popular. For executives/businessmen, turning their cellular phones into modems is no longer a novelty. Wi-Fi spots could make this possible.

CONNECTION SPEED OF CELLULAR PHONES

To understand exactly how cellular phones run, one should at least understand the essence of connection speed. Connection speed is important, especially when using cellular phones to connect online. This will determine how fast you can log on to the Internet and enjoy advance mobile features. Mobile phone features and network services may affect connection speed.
