Where will cell phone technology take us? With the introduction of the newest gadgets every year, the experts have given us the technology to put almost everything we do into one little mobile device.

Once just used for simple person-to-person contact, the cell phone has grown up a lot since its introduction in the 1990’s. Even your basic cell phones offer a selection of advanced features. Will it ever end? Will our mobile phones run our daily lives? Unlock our cars perhaps? Be used as a remote control for our television?

Of course, you can place calls with your mobile phone from almost anywhere and at anytime. Of course there are still a few places out there where the signal antennas don’t reach, but before long, this wont matter much.

Another feature that is more common on phones now is text messaging. This works just the same as instant messengers on our computers. People can talk to each other via text. This makes conversing easier when one person is otherwise occupied and cannot keep an actual conversation at the time.

Another feature most phones have nowadays is a digital camera. This feature has both its pros and cons. Most people don’t carry a camera with them at all times for those moments when we wish we did have one. They have proven helpful in situations like car accidents, criminal
situations, and even catching the occasional embarrassing moment on film.

But there have also been arguments in regards to privacy. People have been found using the camera phone for spying on other people in places like dressing rooms and under tables. Shame, shame.

Cell phones now offer so many more advanced options. Things such as MP3 players, FM radios, GPS services and advanced Internet capabilities. Someday, our mobile phones may replace our notebook computers in their capabilities. Let’s see what happens.

Why aren’t all cell phones compatible? There are two answers to this question. First, there are various different types of radio frequencies and encoding services which different cell phone services use - and if your phone doesn’t receive the frequency and encoding of the local service, it becomes, of course, useless.

The second problem is a commercial issue - your phone will only work on other companies’ services if there is a cross-billing (i.e. roaming) agreement between the mobile network suppliers. Roaming is common within the US, but becomes more problematic internationally.

To get cell phone service in another country you need both a compatible phone and a compatible account. Your best bet is to rent a cellular phone, either in the US or overseas, but be sure you get one that will be compatible internationally in the countries you plan on travelling to. There are several different ways of getting airtime as well. Read on for an explanation of all these issues and suggestions on the best way to get a phone working.

Frequency and Compatibility Issues

The good news is that almost everywhere in the world (except for the US and Canada) uses GSM type digital cell phone service. This service was originally at a frequency of 900 MHz and now increasingly is being upgraded to an 1800 MHz service. If you have a GSM phone, in theory you can access service in 212 different countries! Although the US and Canada have some GSM service, most cellular phone services are of a different type and a different frequency as well!

Unfortunately, the GSM service in North America is in different frequency bands to the rest of the world - 1900 and sometimes 850 MHz instead of 1800 and 900 MHz. And there is no way that a 1900MHz phone will work at 1800 MHz (or vice versa). Frustrating, isn’t it!?

Note that not all other countries use regular 900/1800 MHz GSM. Notable exceptions include Canada, Mexico, Japan, Korea, and some Central/South American countries, although there may be some limited coverage GSM networks in these countries, and/or GSM networks at the US 1900MHz frequency.

How Cellphones Work? - Learn about wireless technology, check out our phone buying guide, read cell phone reviews and compare prices and features on wireless accessories.

Mobile telephones have progressed a long way from their humble beginnings as the analog “bricks” of the 80’s as technology has offered increasingly more complex features and options. Once no more than just a phone, now the average new cellphone has more on-board processing power than the combined computing power used to land men on the moon. Miniaturization, modern programming, and constantly improving technology driven on by a hungry market means that the cellphones of today are not just a phone, or even an organizer, but instead, they are a centralized multimedia platform. They offer many of the same advanced features as a PDA, like Bluetooth, flash card compatibility, radio, and fully featured integrated digital cameras. Much like the cameras found on PDAs, the digital photography offered by multimedia phones is not brilliant, but rather better suited to casual photography of friends at opportune moments. The advantage of having an integrated cell-camera is that as a phone is something that people tend to always carry with them, they will always have a camera handy.

If high quality digital photography is what you’re after, then you’re better off buying a mobile phone and camera separately. While camera technology is getting there for things like PDAs and mobiles, the range of advanced options for a cell phone camera don’t even translate to the standard set of features for a basic digital camera. A comparison of some prominent models on the market today follows, giving consideration to the cost, feature set, and level of quality offered by each device.

The Palm Treo 650 Smartphone runs the Palm OS version 5.4 on a 312MHz Intel CPU. It has 23MB of user memory available, expandable with the addition of either an SD or MMC flash cards. The display is a 320×320 pixel 16-bit color TFT, and it features a 0.3MP digital camera, capable of taking photos or capturing video. Feature wise, it’s impressive, but doesn’t weigh up against similar products for the price. The camera in particular is under-powered for the amount of processing behind it. A Smartphone 650 will set you back about $550.

The Sony Ericsson W800i has 32MB of user memory, and comes free with a 512MB Memory Stick Pro flash card. Featuring a display resolution of 176×220 pixels, and a 2 MP digital camera, it is fairly light on the features, and would be best described as a basic high-end mobile phone. The 2MP digital camera goes some way towards justifying the cost, but it doesn’t compare to buying a digital camera separately. The W800i will set you back around $480.

The Nokia 7610 is a competitive entry on this list, featuring a fairly rich feature set by comparison to the other examples. However, it has only 8MB on-board memory, expandable via a MultiMediaCard flash card. It comes with a free 64MB MMC, with a 176×208 display in 16-bit color. The 1MP digital camera supports a very wide range of image formats, as well as two modes of video in low or medium resolution. It supports multiple video formats, has a 4x digital zoom. The Bluetooth enabled system itself has a web browser and email client. The main problems with this phone are the relatively short lived battery, and the small amount of on-board memory. But at just $310, the feature set gives this phone serious bang for the buck.

If we compare each of these to a normal digital camera, it is easy to see why they are not a good choice if you intend to focus on photography. $350 gets you a Canon SD500 7.1 MP digital camera. It features 3x optical zoom, along with 4x digital zoom, Television AV/out port, proper strobe flash with red-eye reduction, heavily customizable setup, optional automatic lighting conditions compensation, a tripod mount point, full motion video recorded at effective resolution of 0.3MP. It has an SD card slot, and a host of other features too numerous to name. This is not an elite, professional grade camera, however it outperforms every camera phone listed by at least 3:1. and at a lower cost too.

Cellphones have evolved to a point where they more closely resemble a laptop than anything else, combining a truly impressive range of multimedia technologies into one tiny device. Displays are improving rapidly, as is the level of functionality offered by modern mobile phones. As they become more numerous, these features will become increasingly useful as vast networks of people, all armed with such versatile devices will begin to take shape. As of now, however, they are fairly unfocused in their capabilities, offering a very wide range of features, but not delivering any one of them so well as to replace the technology from which the features first came from. While camera cellphones can have their uses, they still do not lend themselves well to high quality photography. For casual use with friends, or general purpose use, a camera phone can be a lot of fun, and while it combines a lot of devices into one convenient package, it doesn’t deliver the a high level of quality.

Cellphones are quickly becoming an integral part of our lives. They increase the convenience factor, help us stay organized, and keep us in touch with the people that we love. They can also help us keep informed!

As cellphone technologies increase, cell phone manufacturers are finding new ways to pack great programs into their cellphones. One such program that is being built into cellphones now, and will increase in the future, is the RSS feed capability.

Having this capability will mean that your cellphone can act like an MP3 player, and perhaps you already have a cell phone that has MP3 player capabilities. But in a cellphone with RSS feed capabilities take the MP3 player format one step further.

The word “podcasting” was coined in 2004. It is a technology that no one heard about until recently but is gaining popularity at an exponential rate. A podcast is like a radio program that broadcasters create in an MP3 format and attach it to an RSS feed on their web site. Computers and cellphones with RSS feed capabilities can grab the MP3 file and download it automatically. This means that every time the podcaster makes a new show, your computer or your cell phone can automatically pick it up.

(A quick note on terminology: podcasts and punchcasts are virtually the same thing except that podcasts are typically the “radio show” that goes to your computer, while punch casts are considered the ones that end up on your cell phone, even if they are the same show in the same MP3 file.)

In the Podcasting For Fun & Profit you will learn more about what podcasting is, how it can operate for free, how you can hear podcasts at your convenience and how you can begin to create your own podcasts.

You’ll find examples and exercises that take you through it every step of the way. And once you know more about what podcasting is and how to podcast, it takes it to the next level by showing you how to create great podcasts that sell. And it finishes off by showing you ten specific ways to make money from podcasting.

You’ll be surprised at how easy it is to get started and how much potential there is in this new industry. And once you’re done reading Podcasting For Fun & Profit I believe you’ll want to do the same thing I’m doing now and write to everyone you can about how exciting podcasting is and what a great opportunity it can be.

The value of listening to podcasts on your cell phone is tremendous. While most people have not heard of podcasts, there are literally thousands and thousands of podcasts out there, and each one is designed for a specific niche: the baseball enthusiast, a wine lover, a news junkie, an entrepreneur, and the list can go on and on. If you have a hobby or interest, you’ll probably find a podcasts on it… or 10 podcasts on it!

Aside from topics, podcasts vary in length and quality: just like television shows, they can have an interview format or a quiz show format or a monologue format, to name a few. They can be well done or poorly done.

Here’s how it works: you find the podcast you are interested in and subscribe on your cell phone (it’s free) and every time the podcaster creates a new podcast and attaches it to the RSS feed, it gets automatically loaded onto your phone.

So now you can stay on top of all the exciting news in your industry, or in a hobby or an area of interest that you might have and you can do it all on your cellphone!

The advent of the digital camera has changed the entire scene of photography. Not a long while ago, there was no concept of still or video editing. Now, there are softwares that do every alteration one can imagine. The video capture card makes the editing even easier.

The amazing technology cell phones have these days is surprisingly growing and developing.

Cell phones started out as an idea for a mobile phone that can be used from a car, within a given range. This was happening back in 1947. Since then, their purpose was achieved and greatly exceeded.

The name comes from the word cellular combined with the normally used word, phone. Cellular because their whole technology is based on cells of signal. Each cell has as a centre a transmitter that assures the mobility and the great range, almost worldwide, of mobile phones. These transmitters are placed in such a way so that they can form a network with absolutely no uncovered spaces. Not all portions have been covered, but the civilized and populated locations all have mobile phone operators and coverage.

Nowadays, mobile phones try to include as many technological areas as possible. There is no cell phone out there that is only a cell phone. From watching TV to playing games, taking pictures and making movies, from real music to color display, they have it all. Some phones even have Windows from mobile on them, just like PCs. Others can actually compete with game consoles like Nintendo because they are kind of a miniature game console themselves.

The extreme competition out there makes developers want to achieve more and more with their phones. Japan has always been a pioneer in the cell phone industry, they had TV and camera phones long before they appeared in America and Europe. Japanese manufactures and worldwide producers try every day to come up with new things for a cell phone, following a fixed goal: the perfect phone that can stand for all multimedia and communication devices out here, a phone that combines everything from communication to utility and work.

So, in the near future the cell phone might offer us a great surprise. How knows, they may try and develop some kind of holographic graphics. No matter what the next step is, the industry is certainly improving every minute, even as we speak and cell phones have a bright future ahead of them.
