The Ideal Way of Today’s Life

Cell phones, more popularly known as the smart phones in the present arena, are undoubtedly one of the best examples of technology that we can boast of, in the last 90 years. A classic product emerged from a human brain and took the shape of cell phones in the early 1900s. Since then there has been no looking back. With each passing day, latest techniques kept on adding to this cellular electronic device, making it the handiest, powerful and useful product today.

The technology started with the simple sending and receiving radio signals through innumerable cellular base stations that are fitted with microwave antennas. However, this means of wireless communication added many new technologies to its system and provided several new services and applications to the users.

Together with the basic voice function, today, we have text messaging services, e-mails, internet services, Bluetooth, infrared, camera and video recording facilities along with sending photos and videos through MMS, downloading ringtones and also picture and videos just to name a few.

There are several latest technologies in use for the cell phones that that have been devised to make our lives much faster, simpler and trendy.

The GSM or Global System for Mobile Communication and CDMA or Code Division Multiple Access differ only in the way the two share space in the radio spectrum. While the former is more popular in Europe and Asia, the latter is used majorly in the United States. However, both work on the ability to provide high-speed internet access to these hi-tech devices.

With the application of all such technologies, the cell phones have become an asset in the educational field too. It can be used for learning activities both inside and outside the classrooms. Cell phones act as an excellent resource-collecting device for students.

The camera and video recording facilities can be used to full extent for capturing all-important data that can be used for documentation in the later stage. The data can also be sent instantly with the use of internet services available over phone to the teacher concerned if required. It can help students in assignments like test message home assignments and oral quizzes.

The cell phones can enable the students to hear educational radio broadcasts and to create instant podcast of their gathered information. Students can call up toll free numbers from their cell phones and get their doubts cleared within minutes. More importantly, they are an assistive technology for students with visual and hearing impairments with their audio and video facilities respectively. Students can also use their cell phones to organize their resources through innovative guides such as Google calendar.

Apart from this, the cell phone technology has also become a powerful tool of investigation in the hands of the investigation bureaus. The call data records maintained by the cell phone companies help the investigators in collecting leads and evidences. The cell phone technologies can also help the police to reconstruct the location of the cell phone user instantly. The standard radio tracking technology and the latest triangulation technique comes the handiest in such cases where the department needs to know the whereabouts of the suspect.

The Future of Mobile Phone Technology

One thing is certain with mobile phone technology; its development could be seen to be infinite, as manufacturers will never run out of new ideas to make the latest handsets work faster and easier to use. Modern Smartphone’s are a prime example of this, packed full with the latest applications, which run on ever more advanced operating systems all with the aim of catching the consumers eye.

There has been one technology banded around mobile phone shops around the world for the last 12 months “3D screen enabled handsets” 12 months ago it was but a rumor but now it is no more! As the future Smartphone will definitely have a 3D User interface added to its already long list of features. Currently LG seem to be the manufacturer with a handset closest to launch.

LG are not giving full package specs but they are pointing out to have improved the cross talk problem (Well, the instant where your neighbor could see everything you type and watch on your phone). The improved parallax barrier is the trick they have used here. But one company that has been tremendous on getting it right on the parallax barrier is the Samsung 3D mobile phones. Wonder if LG will smoke out Samsung on this aspect. Sharp 3D mobile phones also hit the market a while back, and I must say that was a breakthrough for Sharp; they were even buffed up when their 3D idea on Nintendo hit it big in the market.

So 3D mobile phones are what should be on my to-get-list? But I have a problem keeping with the trend; especially when the whole idea of 3D technology on movies and games is yet to settle in my head. The whole Optimus 2x idea has my head in the cloud when my only understanding of Optimus is the autobot superhero in the Transformers movies.

But one thing is certain; to get your hands on 3D mobile phones like the LG Optimus, you will have to spend a lot of money, as all new technology is highly priced when first available. Do not let that put you off though as with all technologies, once 3D handsets have been around for a while the technology will become as common as cameras are in today’s mobiles and the prices on PAYG, sim free and pay monthly contract will fall to more affordable levels.

Applications and Operations Behind Different Types

Semiconductors will not function if they do not possess electrical conductivity. The system takes place in the conductor’s connection with the insulator. This is perhaps the most basic among a list of assumptions behind semiconductor technology. But since this is very basic, there are yet other principles to take note of. In this regard, it pays to take a glimpse of the semiconductor types that are significant in some enterprises.

Semiconductors are very essential in technological advancements especially in mobile phone, computer, television and radio production. They are also highly crucial in production of transistors. In understanding more about semiconductor technology, it pays to take a look at its four types.

First kind of semiconductor – intrinsic

An intrinsic semiconductor is sometimes known as the purest of all semiconductor types. It contains thermal materials that have the ability of lessening covalent bonds as they freed electrons. Part of its work is to go to a solid mass for the support of electric component conductivity. In situations where the covalent bonds lose their electrons, electrical properties of the semiconductor will get affected.

Second kind of semiconductor – extrinsic

Aside from the intrinsic semiconductor there is also the extrinsic semiconductor. When compared to the intrinsic version, the semiconductor technology for extrinsic semiconductors rely upon doped or added particles. With this fact, it is also known as a doped semiconductor. The additional particles play a vital role in transforming the conductivity characteristics of the electrical component.

Here is one concrete sample for extrinsic semiconductors. Silicon, the most usual semiconductor, may be used in order to come up with a gadget. Each atom of silicon allocates four categories of valence electrons through a process known as covalent bonding. If silicon will be substituted by five valence electrons of phosphorous, four of the covalence electrons will be put together while the remaining one will be free.

Categories of extrinsic semiconductors – N-type and the P-type

Wrapping up the four classifications of semiconductors are the two sub-classes for extrinsic semiconductors. One is tagged as the N-type whereas the other is the P-type. The N-type is comprised of electrons and holes. The former plays as majority carriers while the second plays as minority carriers. This signifies that the electron’s concentrations are more than that of the holes.

As for the P-type semiconductor, it acts opposite functions with that of the N-type. To explain further, the P-type semiconductor technology contains holes that play as majority carriers while the electrons become minority role players. In some instances though, there are systems that follow a P-N Junction. This takes place when a P-type semiconductor is found at one side of the system even if the N-type was already made in the other side.
