Tips for Buying a Cell Phone PDF Print E-mail

There are so many sleek and impressive looking cell phones on the market these days that it's hard to resist the temptation to buy one. There is perhaps very little in the world of modern technology that now rivals the prevalence of the cell phone. Just imagine -- it can help you communicate with practically anyone at practically any time. Plus, you look good doing it, too.

Today's cell phones are so much more than means to communicate. You can use your cell phone as a personal planner, check on breaking news on the internet, send email, take photos, take videos, play games, send text messages and even dial numbers by through mere sound of your voice. Of course, having a phone with all this is not cheap, so it's important to determine just exactly what we need our cell phones to do.

The first choice is almost always dependent on our preference for a wireless service provider. The key items here are the kind of coverage it offers and the type of monthly service plan it has in your location. Once done, you will then have to select from the wide array of phones that your service provider has to offer.

Next, you have to think of the phone's features. If you're a world traveler, then you need a phone with global wireless standard. You will probably need a dual-mode phone that can communicate in both digital and analog. These are much more dependable for globetrotters than single-mode models, especially if you will be going to isolated places or rural areas where digital service may be nonexistent.

The next decision you will make is probably the most fun one: design. Do you want one of those phones that are designed like a clamshell and just flip open? Or are you more inclined towards those that look like candybars and don't flip open? For convenience, flip phones are tougher to use, especially if the base is lighter than the cover. Would you like a phone with a dual screen, the one with a small LCD on the cover as well as an internal display? The main considerations are that the phone should be easy to use, comfortable to your ear and made of a design that reflects your personal tastes.

Finally, you will want to decide on special features. What do you want your cell phone to do? Oftentimes, this consideration is tied in to how much we are prepared to spend, so it's not that difficult a decision after all.

The Past And Present Of Mobile Phones PDF Print E-mail

From the Motorola Dyna-Tac of 1973 to the Nokia N-95 of 2007, mobile phone technology has evolved more in the past three decades than computer technology has in past six decades. The number of mobile phones outnumbers the population in 30 countries (according to Informa Telecoms and Media), and 80% of the world's population today can have access to mobile phone or cellular phone services. There are only a limited number of mobile phone technologies, but a very large amount of mobile phone manufacturers and cellular phone service providers. In places like the European Union and India, there is no charge for receiving phone calls on a mobile phone. Today, mobile phones are the cheapest means of communication.

Mobile phones became accessible to most of the world mainly because of technological advances that decreased the associated costs. Competition among mobile phone service providers to offer prepaid mobile phone services resulted in an even more increased mobile phone penetration in developing and under developed countries.

Mobile phones today are not just a means of communication. Text messages came as a value added feature in the mid 1980s. In Japan, people use mobile phones to pay their bills. Elsewhere in the world, people use mobile phones to browse the internet. Today, mobile phones that can take photographs and capture video clips are the norm, at least in developed and developing countries. Mobile phones that can communicate with other electronic devices using Bluetooth technology are no longer news. Still now, there is confusion as to whether mobile phones take over computers or computers move to hand-held PDAs. Mobile phones today are all-in-one communication devices, duplicating (or multiplying) as phone books, entertainment gadgets, digital cameras, internet access devices, and personal computers.

The latest main mobile phone technologies are GSM and CDMA. People are not very concerned about which technology their phone uses. GSM stands for Global System of Mobile Communications, which, with its standard compliance, ensures worldwide roaming for its users. Someone buying a mobile phone in the UK can use that same phone in Japan and can receive calls to the same number as the subscriber would in the UK. EGPRS or EDGE is an extension of the GSM System that is used for high speed video conferencing and internet access.

CDMA technology offers voice clarity and faster data transfer. CDMA is not used in certain regions of the world, such as the European Union, making the CDMA handsets mostly useless if roaming internationally. CDMA and GSM technologies are both available in countries like India, while in most countries you have only one choice. GSM is the only standard available across the EU, but people have to depend solely on CDMA while travelling to Japan or South Korea.

The price of mobile phones today runs from USD 20 to up to USD 10000. Features range from talking and messaging to recording 30 minutes or more of high definition video. Choosing one of the mobile phones today is a difficult task for the poor as well as the rich.
