Technology Toolkit

Mobile phones have been the most fascinating gadgets that have acquired a lot of appreciation from the people all over the world. The exciting models of different brands that are presented keep you engrossed for a longer duration of time. The best selling brands incorporate all the latest technologies. Here you will read about the fascinating history, technology, and various use of one of the most revolutionary discoveries of the modern world.

Until a few years ago, the land phone had been the kind of the communication world. Then a smart boy named mobile phone strolled into capture the minds of ladies and gents traveling with them and has been ruling the roost since then. Here we examine how this miracle came about.

The mobile phone accompanies us everywhere, any time. This wireless wonder traces its ancestry to a US engineer Don Wing, who introduced for the first time a prototype model in the year 1947. A mobile phone is also called a cellular phone because the mobile phone operates on antennas installed in base stations known as cells. These bases stations are erected at strategic locations all over the world.

The initial mobile phones are big, much bigger than the sleek and slim models available today. These were too big to fit in our palms. They remained fixed in one place. It was only in 1973 that a smaller and mobile handset was developed. It was built by Martin Cooper, who was the systems general manager of the Motorola Company.

After a few years in 1979, mobile phones were manufactured in large numbers and offered to customers for sale. Since then the popularity of the mobile phone has been taking leaps and bounds all over the world, and has become an integral part of most people like the ubiquitous wrist watch.

Currently, two types of mobile phones are available in the market. The first one is the Advanced Mobile Phone System (AMPS) developed in the US in 1976. The second type is a system developed in Europe called the Global System for Mobile Communication (GSM). The GSM system has become more popular because you can use the same number from any country in the world for sending and receiving messages. The mobile phone technology is constantly evolving to such an extent that every now and then a new model with unique capabilities are introduced.

Now it is possible to do a large number highly advanced and technology focused activities such as watching movies, listening to music, news updates and internet browsing. An of course, there are mobile phone cameras with inbuilt cameras for high definition photographs and motions pictures! There as also handsets those integrate the latest technique of Navigating, making it easier for the people to find ways and locations from the maps. Another popular facility available on the mobile phone is sending SMS, which means Short Message Service.

There are also new arrivals such as iPhones and Ipods, some with touch screen facility and Java support. Java support means you can download third party software and applications as are available with one of the latest product, the Sciiphone with upgraded firmware to include popular flow touch or flow control. In whatever way you look at it, the mobile phones are advancing at a rapid rate, not only in the market but also technologically.

Mobile components present the existing architecture of the mobile component and architecture already used on the web component and then we propose a new architecture based on new technologies.

Before Mobile component designing and technology, there were other existing technologies, also. The main reason for choosing a technology so far was mainly the economic factor. Almost all the technologies that are described below are free of charge and open source.

Many other components also come into picture after rising of these mobile components. Java servlet were not used in previous technologies. However, in the present system, Java servlets are used as the intermediate between user and system.

Web forms are filled by the user and the data are collected by the servlets and forwarded to the proper mobile agents. The result, which is created by the agents, is forwarded by the same servlet back to the user. In order to have a web service with servlets we needed a web server that supports them.

The only web server that supports servlets and its open source, free and easy to use is the Apache Web Server. The Apache Web Server in the current state does nothing more than working as a regular web server and executing the servlets.

In order to support the idea of the medical mobile teams we choose the approach of the agents system. Each user has his own agent that handles all his tasks. After examine all the agent platforms, we came to the decision of using the voyager mobile agents platform.

Its based on Java and its very easy to use. These agents have direct access to the system database and they create the dynamic web pages (HTML or WML) that are returned to the user. Because of the nature of the data, we needed a secure and robust database system.

SQL server is the database system that provides us all the needed features and much more. All the system data are stored on the SQL server 2000 and access is granted only to the mobile agents and to the desktop installation program.

First of a basic goal of the system is to provide a data access to users from almost any device. Users can access the system with any device that supports a simple HTML or WML browser through WLANs, LANs, GSM or GPRS networks. User communicates with the servlet server (Apache) and sends his requests.

In mobile computing world, migration is important for survival. Mobility originated from the desire to move either toward resources or away from scarcity. Mobile computing is about both physical and logical computing entities that move all system data from one source location to another destination.

Mobile computing provides some physical entities that are computers which change locations as and when required. Here, logical entities are instances of a running user application or a mobile agent that automatically configures device. Therefore, mobile agents can migrate any where over internet.

Nomadic computing refers to limited migration. Migration is within a building at a pedestrian speed. Interleaved pattern of user relocation and in door connections is also refer to nomadic access. For example, in the same vein, users carrying laptop with DIAL UP modems are engaged in nomadic computing.

If the user needs access to a network such as the internet on the go, they must resort to slow wireless WAN systems primarily intended for telephone use. Higher speed wirelesses LANs are only available in specific sites.

However, there are some constraints, technical and some other limitations while doing mobile computing. For Example, when working mobile, one is dependent on public networks, requiring careful use of VPNs. Therefore, there are some leaks to security standards in this case.

Also, there is some power consumption in the process. Since the grid cannot be used, mobile computers must rely entirely on battery power. Combined with compact size, this means unusually expensive batteries must be used. Hence battery power should be properly maintained for better utilization of this technology.

Sometime, weather and terrain problems as well as distance limited connection exist with some technologies. Reception in tunnels and some buildings is poor. Potential health damage from cellular radio frequency emission is not known yet.

However, more car accidents are related to drivers who were talking through a mobile device. Also, cell phones may interfere with sensitive medical devices. We can say that human interface has been increased with mobile devices.

So, there can be some health problem regarding to electromagnetic interferences. Yet these problems are not proven. But precaution is the first step to cure. As HMDs are still uncommon, screens are often too small. Keyboards are impractical, especially one handed, and alternate methods such as speech or handwriting recognition require training.

Mobile computing is a generic term describing ones ability to use technology while moving, as opposed to portable computers. Distributed computing as we know, works on static wired network. Hence it is more secured as compared to any other computing mechanisms here before.

These days virtually everyone has a cellphone. People who never dreamed they would be so connected are now completely addicted to their cellphones. Whether they need them for conducting business or maintaining personal relationships, cellphones have become an indispensable tool for the modern world.

Most cellphone owners sooner or later experience a situation where they hear their cellphone start to ring in public. The only problem is that it is a generic ring, and half the people in the crowd reach for their cellphones! Most of us want our cellphone ringtones to be more unique than that, if not for personal identify reason than certainly so that we can identify our own cellphone as the one that is ringing in a crowd.

So, eventually most of consider ways to personalize our ringtones. Some cellphones come with multiple ringers installed, but not very many. So, we eventually realize that the best way to personalize our ringtone is to download one, or more, from an online ringtone service.

The options for downloading ringtones start with the option of downloading from the carriers. Just by going into the phone menu, you can select an option to search for ringtones from the collection offered by your carrier. This is certainly convenient, but as in most situations in life, you pay extra for that convenience. When purchasing a ringtone through a carrier, you can expect to pay anywhere from $2 to $3 per ringtone! This is certainly a good deal of money just for a 30 second song snippet.

It turns out there are less expensive options. One such option is to purchase individual ringtones from specific websites. There are websites where you can purchase individual ringtones for $1 to $2 each. This is a big improvement over what is offered by the carriers.

Another option is to take advantage of the free ringtone offers you see advertised all over the place. It sounds pretty good – just enter your phone number in a web form and you get 10 or 12 free ringtones.

The problem is that there is a catch, and in fact it is a big catch. When you join a service like this you are really joining a monthly ringtone service that costs anywhere from $9.99 to $19.99 per month. For this monthly charge you get some extra credits to download additional ringtones. But do you really want to pay over $200 just to download some ringtones?

In other words, those free ringtone offers can be pretty deceptive. The ringtones really aren’t free at all if they cost you $10 or $20 per month. Usually the notification that you are joining a paid ringtone service is buried in the fine print on the signup page. Many people sign up and don’t realize what has happened until they get their next phone bill. As you can imagine, the carriers get an enormous number of complaints about these services.

So are there any other options? Yes, in fact there is a service that lets you pay a single yearly fee of less than $24. During the entire year, you can then download an unlimited number of ringtones and wallpapers for your cellphone. You get a huge selection of the same ringtones and wallpapers offered by the other services but at only one tenth the yearly cost. If you plan on downloading any amount of ringtones and wallpapers, it is definitely in you best interest to explore a one time payment service like this to get the most value for your money.
