Today i tell you aboat cell phones, Smartphones. (It's a Long history)

Cell Phones. 

Doctor Martin Cooper invented the modern cell phone. He invented the technology responsible for the cell phone when he was the Director of Research and Development at Motorola. Dr. Martin Cooper is also known as the first person to make a call on a cell phone. His revolutionary call took place in April of 1973 in New York. He is currently the CEO of an antenna corporation.

The Cell Phone's AncestorsThe modern cell phone originated with Martin Cooper; however, in order to completely understand the invention of the cell phone, you actually have to go back to the year 1947. It was then that the underlying technology that makes cell phones possible was invented. Known as hexagonal cells for mobile phone base stations, cell phones were invented through a joint effort between AT&T and Bell Labs. They were not actually used until the late 1950s.

Before the invention of hexagonal cells, the military (and some wealthy individuals and businesses) relied on radiophones. These phones required a large backpack device to transmit the phone's signal to a nearby station. With the invention of hexagonal cells in the late 1940s, radiophones were rendered almost completely useless.

The Cell Phone's CompetitorsThere was another network competing for the title of "portable handset". The 0G network devised a "phone for the road", but this phone never became a true mobile phone because it was limited to a single cell. It was not until the hexagonal cells and a feature called handover was invented in 1970 which made mobile phones to be employed on long trips that required moving in and out of cells.

Mobile Cell PhonesOnce the handover feature was implemented, it was only a matter of time before the cell phone was miniaturized sufficiently to be mobile. Yes, there were mobile phones before Martin Cooper's invention in 1973, but they all required some sort of backpack or car-mounted unit to be used effectively. It was not until Martin Cooper came along that the mobile phone was turned into something that was actually a mobile in its true sense.

After 1973, cell phones took off slowly, partly due to their large size, highly cost, and relative uselessness for most individuals. The mid 1980s brought about fully automated cellular networks which mildly decreased the price and increased the amount of people using cell phones in their cars. It was not until the early to mid 1990s that cell phones were made small enough and cheap enough to appeal to the average consumer.


Modern technology moves fast and furious, especially when it comes to capabilities of the smartphone. Just what is a "smartphone"? Actually there are no agreed upon or exact definitions for the term. Most would agree however that smartphones do more - much more - than what Alexander Graham Bell first envisioned when he invented the original telephone back in the 1870s.


The smartphone differs from ordinary mobile phones in that they are capable of advanced functionality because they contain software applications that can be run directly from the phone itself. This software is typically open-source, an advantage that makes adding applications as easy as loading them onto the phone via wireless downloads. Today, these devices are not considered very "smart" unless they can accomodate a datebook/calendar, advanced internet connectivity, photography, music and even video capability.


IBM was the first to venture into the business of offering consumers a highly advanced mobile phone. In 1993, the company introduced what could be considered the world's smartphone - simply called Simon. Considered low-end by today's standard, this first smartphone featured an amazing array of features - email, address book, clock, calendar, note pad, and even the ability to send and receive faxes.

During the mid-90's, Nokia began to heat things up by introducing its first line of smartphone - the Nokia 9000 series. This phone was not only the first in a series of popular smart phones manufactured by Nokia, they were also the most expensive, coming in at 20-40% more costly than its rivals. The Nokia 9210 was indeed the first real and true smartphone due to its open operating system.

Cutting Edge Smart Phones

The 21st century has spawned smartphones that are incredibly powerful and easy to use. Touch-screen functionality has become the norm and manufacturers such as Apple, Nokia and Research in Motion are furiously vying for the smartphone consumer and business dollar.

Apple changed the smartphone industry with its introduction of the Apple iPhone in 2007. Nokia has since countered with the unveiling of its Nokia XPress Music Phone in 2008. The Nokia 5800 is a touch-screen lovers dream that includes just about every feature a user would want. The handset even comes with millions of downloadable music tracks at no cost. Google recently joined the fray by introducing it Android phone during the same time period.

The Future

Could the smartphone get any smarter than it already is? Sure can! In the not so distant future, virtually everyone on earth will be carrying some type of smartphone - devices that will make today's handsets pale in comparison. Increased bandwidth and speed will allow phones to be able to handle video in real-time with no problem. In the future, these mobile handsets will be indispensable to daily life, used for a wide array of functions, including consumer purchases, banking, real-time video connectivity, advanced GPS tracking, entertainment and much more.

Mobile Phone:

Nowadays, the mobile phone is so important to us that it’s hard to think of life without it. However, they're a relatively new invention. This article explores the history of the mobile phone & questions what the future holds for it.

On 3 April 1973, Dr Martin Cooper, who was a Motorola employee, placed a call to rival Joel Engel, who was head of research at AT&T. Doctor Martin made the call while he was walking the streets of New York & did so through the first Motorola DynaTAC prototype in front of journalists. 

The earliest mobile telephones were dubbed first generation telephones, often referred to as 1-G. These devices were the very first real mobile telephones, although they were then known as cellular mobile radiophones, & were based on analogue signalling. The analogue signal was the main difference between these first generation mobile telephones & their second generation cousins, which came out a few years later.

Second generation (2G) mobile phones were first released in the nineties. Unlike 1-G phones that were analogue, 2G phones use digital signalling to provide voice services & for text messaging & WAP internet access. 

Some of the benefits of 2G phones are that they use lower radio signals, which require less battery power. This means that phones lasts a lot longer between charges, so batteries - & therefore the phones themselves - can be made littler. As well as this, 2G phones offer more privacy. Indeed, digital cellular calls are much harder to eavesdrop on than 1G phone calls. 

The name 2.5G is used to refer to the phone technology that is post 2G, but not quite 3G. However, while the terms 2G & 3G are officially defined, the term 2.5G is not. In fact, this term was invented for marketing purposes only.

The earliest pre commercial 3G mobile phone network was launched in Japan in May 2001. Later, 3-G was released commercially in Japan on October 1 2001.

3G is the third generation of mobile phone standards and technology, which succeeded 2G mobile phone technology. The birth of 3-G technologies enabled network operators such as orange to offer their users a bigger range of advanced services. This includes broadband internet, as well as high tech video calls.

Despite the success of 3G, there's also been some complaints about it. These include criticism over the cost of 3G phones, as well as concerns over the lack of network coverage these phones get because it's still a pretty new service.

Ever since the launch of 3G mobile phone technology, people have been talking about 4-G. 4-G technology will signify the future of mobile telephones, creating the most sophisticated handsets & best services to date.
