What is 4G Mobile Technology?

4G mobile technology is how people refer to the next generation of mobile services like the cell phones. It was just made available by at least one provider in a number of places in the US in 2009. Because it is still fresh, there is no established industry standard yet as to what constitutes 4G mobile. Thus, it is simply a marketing term in the mean time.
The letter G, used to shorten the word generation, in the mobile technology world covers the noticeable advances of the past 20-20 years. 1 G technology covered the first widely available mobile phones. Its successor, the 2G technology, began in the early 1990s – switching to a digital format and introduced the concept of text messaging. 3G technology made its mark by improving the way how data is carried, making it possible to have enhanced information services like websites in their original format. The famous iPhone is the best known example of this technology.
4G mobile technology is not yet established to have an agreed set of standards and protocols. This implies that its current features are simply goals and are not yet the full requirements. 4G mobile technology is still in the phase of developing enhanced security measures, since data transfer schemes are drastically increasing. Another 4G mobile technology goal is to overcome and minimize the blips in transmission when one device moves from one area to another covered by different networks. Another thing that 4G mobile technology is still working on is to figure out a way to use a network based on the IP address system used for the internet.
In the United States alone, there are two major systems using the 4G mobile technology. The first one is known as WiMax and is backed by Clearwire – a firm whose primary owner is Sprint Nextel. It began its testing phase of the system in Baltimore in 2008 and was set to expand overwhelmingly into major markets in 2009. The rival system is Long Term Evolution or LTE, which is backed by Verizon. It is expected to be ready for testing in 2010 but will not be available for use until 2012. LTE is hoping to overcome this disadvantage by providing faster speeds and producing cheaper equipment.
Unlike the previous generations of mobile technology, 4G mobile will be mainly used for internet access on computers and carrying cell phone communications. Customers in areas which have a strong 4G coverage can use it for a home broadband connection without needing any cables to be mounted in their household. It can also be used for accessing the internet outside the home without having to be stuck in a wireless hotspot like those that are offered by some coffee shops, airports and libraries.

The Evolution of Mobile Phone Technology
Every month, millions of people worldwide are adding themselves to the mobile phone community. This will go on all because mobile phones are such great devices that using them you can talk to anyone in this world from anywhere, anytime.
Mobile phones provide you an array of feature that you can speak as well as sent and receive data. But, it depends on a model that a mobile phone can contain as many as possible features within. A mobile phone stores contact information of your desired people, sends and receives e-mails, displays you flash news, enables you playing simple games in your free time etc. Mobiles phones integrated with PDAs, MP3 players and GPS system are also widely available. However, only few may know how mobile phones with such integrated features actually work. Knowing the technology, that work behind such mobile phones could sure help you using it extensively. At least a new model is released with newer add-ons every month. If you are in idea of buying a new mobile phone then you also need to be sure about how to buy a mobile phone before your purchase.
At this point, you need to know that the very quite fact about a mobile phone is that its functions similar to a radio. The technologies like telephone and wireless communication been invented more or less in the same period (actually in late 1870′s), soon after these two combined to give us the model for today’s mobile phone. People later started using these radio phones fitted inside their cars and its antennas been mounted on the top. However, because of lesser channels available, more people were not able to use these radiophones. To add, you can compare that day mobile phone to a CB radio or a walkie-talkie to understand it better.
Today, the smarter thing about mobile system is splitting up of an area into smaller cells thus enabling millions of people to use the mobile phones simultaneously. Mobile systems function in a way that within a cell area, at least 56 people can talk on their mobile phone at a time. In another side, to send and receive the tower signals, mobile phones are equipped with low-power transmitters.
Related to technology, its first generation, which used analog signals is called 1G. Digital transmission coming into existence, the number of channels increased which were of 2G mobile technology. The mobile technologies, which were later developed, claimed superiority over the earlier. The current 3G mobile phones offer you unbelievable features like email, stereo sounds and video. In the power consumption part, battery-operated mobile phones normally consume low power and this has made the possibility of having handheld mobile phones.
Another important aspect with the mobile phone is the services offered to the subscribers are of cheap rate. This is because mobile phone system requires a number of base stations in a region to operate its service. But as most people use mobile phones, the cost per user remains low irrespective of large number to based stations installed. A mobile telephone switching office handles all the phone connections and controls the bases stations that function under it.
Anyway, future generation mobile phones are to come which are going to provide us a breathtaking service for both professional use and fun.

History of Mobile Phone Technology
The idea of mobile phones has been around a lot longer than you thought. In 1947 a certain Douglas H. Ring and W. Rae Young, who worked for the Bell laboratories, had the idea of a hexagonal cell for mobile phones.
But really it was not until the Eighties arrived before the first technology actually surfaced, although at the time the mobile phone was not in everybody’s price range. These new inventions of the day could only be afforded if you were extremely well off or very rich.
The mobile technology of the Eighties were nothing like the ones you see today. For starters they were far too big to fit in your pocket or your purse, and because they were so big, they were also very awkward to handle.
Because of their size you could not hold them up for too long before your arm started to ache. Not a good idea really. Also the sound was not very clear; nothing like you get today. The main concept of these phones were to carry in your car when you were out and about.
Motorola were the first company to introduce the first true portable handheld phone device.
1990 brought about the first digital cellular phone call. By then the phones had shrunk considerably.
Actually the first cell phones were only supposed to be for receiving and making voice calls whilst out on the road.
Like anything else with time, technology has moved on since the first mobile phones were introduced. You are now able to do a lot more on it than just the making and receiving of calls, such as text messaging, video calls, taking and receiving pictures and much more. The mobile phone has got bigger technology with its smaller size.
There is no doubt that as we get older; the mobile phone technology will only get better.
