More and more often, we happen to read, on newspapers, magazines or websites, news about development of modern telecommunication technologies. A few weeks ago, for example, Italian newspapers were reporting the news of a father, who ended up under investigation for keeping his teenage kids under control through a cellphone which was turned into a real bug, able to transmit in real time, or record and transmit, whatever was happening around, even while apparently turned off.

This kind of devices, which for your ordinary Joe might be coming straight out of a 007 movie, are actually much more common, much easier, and last but not least, much less expensive than one could think.

As anyone may have noticed by observing the evolution of mobile technology in recent years, modern mobile phones are now much closer to portable computers than they are to an ordinary telephone.

And just like every PC, although with a different installation process, modern cellphones can host a wide array of software, either the normal utilities for the phone’s everyday activities (SMS, email, address book management, photo camera, MP3 player, etc), or specific products that make our phones a real multimedia station rather than a simple conversation device.

Ad esempio, oltre a programmi che, come detto sopra, possono trasformare il telephony in una microspia ricetrasmittente, spesso all’insaputa dell’utilizzatore, esistono anche altri programmi che rendono le nostre conversazioni sicure, codificando la trasmissione e rendendola inintelligibile a chi non sia in possesso dello stesso software e delle relativa chiave di decodifica.

For example, beside software that, as explained above, can turn our cellphone into a real bug, allowing third parties to listen, unbeknownst to the user, to any conversation around it even while turned off, there are also some utilities which, after being installed on a handset, make our conversations secure, by encrypting them, making any interception impossible and useless for any third party without having the relevant decryption key.

Just like a PGP key for email, this software allows to encrypt telephone communications (including SMS), by being installed on user’s handsets, along with a secret 256-bit key entered by all users. After installation the user can access the software from the Main Menu of the phone to place secure calls to other users. To place the call the user needs to enter the normal phone number of the caller from the dialer screen.

When the call is answered on the other end, the software checks for the correct keys on both ends and then initiates a 256-bit encrypted call. Missions and consultants in foreign countries do not need to be bothered of who is listening into their conversations, as they are over a data line which is heavily encrypted. At no point is any data sent over a voice channel or is in clear text type transfer.

This application ensures that information can be sent from anywhere in the world to headquarters within a few seconds. Some information requires to be sent instantaneously and requires an instant reaction. A simple call is to be placed to HQ and a conversation can take place to aid instant decision making.

The Encrypted Call Software is simple to configure. Just enter the 256-bit key on all phones that wish to communicate with each other and you are done. Simplicity of this software should not be mistaken for its performance. In the background the software uses Data Call facility provided by the network provider to seamlessly auto-adapt itself to any GSM network. The end user does not need to enter any complicated settings to make it operational, as an intelligent plug-and-play system ensures smooth operations.

The Defy is a basic slab form factor which bears the IP67 standard for protection against dust, rust and water ingress. The device comes with the same 3.7-inch TFT capacitive touchscreen display that is found on its sibling, Milestone 2, and measures a relatively compact 107 x 59 x 13.4 mm. You can pick up the best deals for the new Defy by going to http://www.best-mobile-contracts.co.uk. User-friendly features The handset comes with partial Adobe Flash support for its Webkit-based browser as well as Motorola’s very own Motoblur UI which provides social networking integration and messaging interface extensions plus widgets. Users will come to appreciate the phone’s Swype text input system as there is no physical keyboard on the device. The Motorola Defy is equipped with a 5 megapixel camera with an LED flash. The flash will be a great help in low-key lighting but it can also be used as an emergency torch in camping trips or when you get caught in the dark. Across the bottom of the display are classic and recognisable controls for Motorola enthusiasts, featuring home, menu, search and back. These are all touch-sensitive buttons and offers smooth navigation across menus. Media player and connectivity The Motorola Defy comes with a versatile media player which supports popular audio and video file formats. The player can be used with the built-in 3.5 mm headphones as well as via wireless Bluetooth headphones. The phone provides you with comprehensive hardware connectivity which includes 2G GSM, 3G HSDPA, Wi-Fi and Bluetooth. There is geo-tagging and GPS receiver to provide location info to your photos anywhere you are on the planet. The Motorola Defy also has DLNA support which allows you to upload your captured content on compatible devices to share with friends and family on your favourite social networking sites.

The cell phone, or as referred to as a mobile, wireless, or cellular device, is a short-range, portable electronic device which is used for the transfer of voice or data over a network, for example a CDMA network. A Definition from Mobile Computing News: CDMA (code-division multiple access) refers to any of several protocols used in so-called second-generation (2G) and third-generation (3G) wireless communications. As the term implies, CDMA is a form of multiplexing, which allows numerous signals to occupy a single transmission channel, optimizing the use of available bandwidth. The technology is used in ultra-high-frequency (UHF) cellular telephone systems in the 800-MHz and 1.9-GHz bands.

In 2007, the total cell phone subscriptions around the world reached nearly 3.3 billion. It is a technology that has exploded beyond measure, an industrial revolution in its own right. This makes the cellphone a valuable commodity. So, with cell phone thefts rising every year, it would be a good idea to keep track of your cell phone at all times. Of course, if someone steals it and it is equipped with GPS technology, Global Position System, well just track it. GPS has a great history as to where it came from decades ago, and now, not just for military purposes, has become a part of civilian use in areas of navigation, getting directions, or making sure your kid goes to school in the morning. One of my friends has that, it alerts him when his son has entered the school, pretty ingenious!

Well, the cellphone world has good news for you: you can do all of this using custom wallpapers. Custom wallpapers are simply small image files that you download onto your cellphone, and then you configure your cellphone to display the image as a background to your cellphone display. The content of these wallpaper images is limited only by your imagination. You can put images that are very personal to you, like pictures of your friends or family, or you can put images that show off your tastes in music, movies, movie stars, favorite places, etc. basically, if it can be placed into an image the size of your cellphone display, then it can be loaded as a wallpaper into your phone.

So what format are the images? Well, this depends on the type of phone you have. And it should be stated that not every cellphone will support custom wallpapers, so check with your internet service provider to see what sort of wallpapers your phone supports.

Once you discover what type of wallpapers your phone can download, you will need to know how to get the wallpapers onto your phone. Some phones will allow you to put your very own digital pictures onto your phone via a data cable. Again, contact your cellular service provider to see if this is possible with your cellphone.

But most of the time, it is a much easier option to download wallpapers from a large ringtone and wallpaper service. It is possible to buy individual wallpapers for anywhere between $1 and $3 each. But if you look around on the web, you can find some services that give you some free wallpapers to start with. You can also find some services that allow you to upload your own images through your web browser, and the service will convert the image into a wallpaper for your phone.

But eventually, if you want to get a continuous supply of wallpapers, you will need to pay to get access. For a small monthly fee you can download lots of wallpapers (and ringtones) to your cellphone. That way you can change your backgrounds to keep your phone fresh and to continually express your individuality to the outside world.

Bullet Protection
The metal casing found in today’s cellphones is not only great for keeping away scratches, but can also be used to deflect bullets. Take the case of Darren Prior, a jewelry attendant who credited his cellphone for saving his life during a botched robbery.

Flash Light
The bright display screen found in today’s cellphones not only makes it easy to use the device in the dark but also allows the cellphone to be used as a portable torch, like in the case of the two stranded hikers who had used their cellphone display screens as glow sticks to direct rescue helicopters to their location.

Personal Surveillance System
Many cellphones now come equipped with a camera which are not only good for snapping personal pictures but can also be used as a personal surveillance device to help protect you from unforeseen incidents, such as a pervert on the subway, a robbery suspect and a would be kidnapper.

Silent Alarm
Apart from keeping in touch, the text messaging ability is a great feature that is not only simple to use but also discrete. This is especially useful if you need to send out a silent alarm, like in the case of a kidnapped boy who secretly text messaged his parents.

Location Finder
Many new cellphones come with a built in GPS. Not only does this technology allow parents to spy on their kids but can also be used a GPS system to find your exact location. Like in the case of the standard couple whose cellphone GPS capabilities enabled Emergency 911 operators to relay their location to on ground rescuers.

Cellphone usage worldwide numbers in the billions. If there is a possibility of injury from these devices, then a lot of people will be affected.

A cellphone is actually a radio transmitter and receiver. It sends and recieves radio frequency electromagnetic waves. The received signals are fairly low level, so I will concentrate on the signal transmitted from the cellphone.

Cellphones transmit mainly at frequencies of 900, 1800 and 1900 Megahertz (MHz). A microwave oven cooks food using a frequency of 915 MHz or 2450 MHz. In other words, the food is not fussy about what frequency you use, as long as it’s in that range, say 900 to 2500 MHz. Which means, cellphones use Microwave Oven frequencies.

A microwave oven puts out a power of about 1000 watts, on average. If you put your head in a microwave oven, it will take about an hour to cook to a nice sizzling crisp.

A cellphone transmits at a power of about 3 watts, and it self adjusts it’s power continually to compensate for poor signal paths, up to a maximum of 5 to 7 watts. Not much, but there’s a twist…

A microwave oven spreads it’s radiation over the whole oven cavity, so that the food is cooked uniformly.

A cellphone has a tiny, array antenna, measuring maybe 2 or 3 cm in length, and it’s right next to your ear. So 5 watts of power is radiating into your head into an area of perhaps 3cm by 0.75cm. That’s a lot of power when concentrated in such a small area.

The cellphone manufacturers have said that they have put “shields” into their phones to keep radiation risks to a minimum.

If you turn around while making a call, does the call cut out or the audio disappear at any time? No, it doesn’t. Radio waves, like light waves, travel in a straight line. If your head got in between the cellphone and the cell transmitter tower, then the signal should be blocked (shielded) by the shield in the phone, as the waves can’t bend once they’ve left the phone.

Which means that those microwaves are going through your head, all the time.

Whenever you’re “on the phone,” you are being microwaved just like the roast in your microwave oven.

So What Can You Do?

If you’ve got a handsfree kit, use it if it’s practical. Don’t use bluetooth – it also transmits radiowaves close to your head, albeit at different frequencies.

If your phone has a loudspeaker, switch it on and speak at a distance. The guy on the other side will still hear you perfectly.

Buy phones with a low Specific Absorption Rate (SAR)

Don’t let children make long calls. Their soft skuls are much more affected than the hard heads of adults. (See “The Stewart Report.”)

Swop ears every minute or so, to give your head time to “cool down” on that side.

Don’t hold the phone next to your ear while connecting – this is when it transmits at maximum power.

Avoid making calls in weak reception areas, as the cellphone will boost it’s output power to make sure it stays connected.

Keep your conversations short.

Use SMS’s whenever possible.

Avoid sleeping with a cellphone under your pillow. Cellphones transmit even when you are not using them, exchanging data and checking signal strength, at regular intervals.

Avoid carrying the cellphone close to your body. This applies especially to the breast pocket of people with heart problems.

Use a landline whenever possible.

Many people have proven health problems from cellphone usage, brain tumors being the most common, followed by loss of memory, impaired brain function and other symptons. Usually these symptons take a few years to surface.
