What Makes My Mobile Phone Work?

The mobile phone has been the gadget that closed the 20th century as having the biggest impact on consumer's lives. Millions of people around the globe are constantly using mobile phones to stay in touch with others.

Here, is a brief discussion on the working of mobile phones.

Mobile phones work as a two way radio system. When you talk through a mobile phone, it converts your voice signal into radio waves. These radio waves travel from the antenna of your mobile phone to the receiver at a nearby base station. The base station then sends your call through the telephone network until it reaches the mobile phone you are calling.
When you receive a call on your mobile phone, the signal travels through the telephone network until it reaches a base station which is close to your mobile phone. The base station then sends out radio waves that are detected by a receiver in your mobile phone, where these radio waves are converted into speech that we hear.

In this entire process base stations are the most important part of the mobile phone networking. The area covered by Base station is known as "Cell", which is hexagonal in shape. When we move from one cell to another "Handover" occurs, breaking connection from the previous base station and making a new one from the current base station which may take some seconds. When all the channels of the base station are occupied, no more calls can be transmitted or received from that particular base station.

Apart from talking, mobile phones are having various functionalities that differentiate it from a regular landline phone like SMS, Web browsing, GPS, games, mp3, FM radio, camera etc. So while sharing your brilliant ideas or just gossiping with your friends via your mobile phone just imagine how it is actually working!

Motorola Milestone XT720

Motorola Milestone XT720 makes its debut in the market following the lackluster performance of the Milestone handset in the UK when compared to the passionate reception in the US for its twin product, the Droid. The unit currently entering the market is essentially Milestone 2 and the company has learned from the dissatisfaction voiced about the original device and addressed all of those issues. The Motorola XT720 has eliminated the keyboard, upgraded the Motoblur functionality, upgraded to an 8-megapixel camera and enhanced the device with a 720MHz processor.

Motorola has also redesigned the device so it has the appearance of a digital camera rather than a traditional cell phone. Reviews of the new design are mixed. Some users appreciate the new design, others are unimpressed. The eight megapixel camera is positioned on the back of the phone, and the quality produces images better than most camera phones. Similar to an Android phone, the menu key, back button, home and search buttons are all placed below the screen. Some users contend the phone has a very masculine design, and that it will appeal more to men and women.

The 3.7-inch WVGA capacitive touchscreen offers a 480 X 854 resolution, and the built-in 512MB of memory can be expanded to up to 8GB with the addition of a microSD card. The performance is acceptable with an Android 2.1 operating system, and there are no noticeable operating hiccups to date. Both the Google Nexus One and the HTC Desire have a faster processor than the Motorola XT 720, but this devices weighs just 160 grams and Motorola's efforts have resulted in a sold design with minimal lag.

While quoted as providing a maximum 13 day standby time and up to 4.5 hours of talk time from the 1390 mAh battery, this is an operating system needing frequent recharging as experienced Android users have found. The phone can be conveniently charged while you are at your desk through use of the available optional Multimedia Station. The standard multimedia formats supported are MP3, AMR, MPEG4, AAC, WMA and ACC files. The Milestone XT720 also sports an FM radio and a 3.5mm audio socket.

Some people will still be wondering if the Motorola Milestone XT720 is worth purchasing. The answer depends on the size of your budget. The Motorola XT720 does not offer the same features and design as the Google Nexus One or the HTC Desire, which many tech-savvy users might prefer. However, if you have more concern about your budget, the Motorola Milestone XT720 is an appropriate and affordably priced alternative to more expensive choices.
