3G Demonstrations

Although 3G is already one of the most common features among handsets today, there are several innovations and changes that had to be done to get it working the way it is at present. Several countries and mobile networks introduced various technologies and efficiencies, through demonstrations to hopefully appeal to the customers that need 3G the most.

Here are some more details on the development of the technology.

First Demonstration

m.Net Corporation created the first pre-commercial demonstration in Adelaide, South Australia, for the southern hemisphere in February 2002. UMTS on 2100 MHz was used for the demo. The demonstration network was made for the 2002 IT World Congress. Hutchison Telecommunications launched the first commercial 3G network, called Three, in April 2003.

As of December 2007, there were 190 3G networks functioning in 40 nations, with 150 HSDPA networks operating in 71 nations, according to the GSA or Global Mobile Suppliers Association. Telecommunications use W-CDMA technology in the United States, Europe, Asia and Canada, together with the support of about 100 terminal styles to function 3G mobile networks.

More on 3G Networks

In Europe, there were volume market commercial 3G services introduced and launched beginning in March 2003. This was by nations, namely the United Kingdom, Italy and a part of Hutchison Whampoa. 3G operators were suggested by the European Union Council to cover 80% of the European national populations as 2005 ends.

Roll-out of 3G networks were also delayed in a number of nations through the big prices of added spectrum licensing costs and fees. In several nations, 3G networks do not apply similar radio frequencies as 2G, so mobile operators should create wholly new netowrks and permit totally new frequencies.

The United States is an exception since carriers function 3G service via the same frequencies as other given services. The license fees in a number of European nations also tend to be high, pushed by sealed bid auctions, the growing excitement over the effects and potential of 3G technology and the government auctions of a certain number of licenses. The expenses of upgrading tools and equipment for new systems also triggered more delays.

Getting Connected

As of June 2007, there are already over 200 million 3G subscribers connected. The number, however, comprises only 6.7% of the 3 billion total number of mobile phone subscriptions all over the world. Japan and South Korea were the very first nations to be connected and launched the 3G, so over 70% of the total mobile phone subscriptions are connected. Italy has the highest number of connections in Europe with 33% of subscribers having the technology. Other countries that also lead include the United Kingdom, Singapore, Australia and Austria, with over 20% 3G migration.

Licenses and Connection

A statistic that might confuse you are counting 3G clients together with CDMA 2000 1x RTT. Via the definition, the total 3G subscriber based with be around 475 million as of June 2007, with 15.8% of all subscribers around the globe. A lot of big countries like Indonesia have not yet been given 3G licenses, as more and more clients await the service. China has postponed the decision to get 3G for several years.

In May 2008, China decided that three 3G networks will be given to China Mobile, the biggest mobile operator. The telecommunications sector in the country has been re-organized.

3G History and Background

3G History and Background

3G has dominated the modern world in just a few years. Although the technology is relatively new, there are already so many devices taking advantage of the functions. You can use it regardless of location, so work and leisure becomes more efficient. You have to know a little about 3G history to know how unique it is compared to other updates in the past.

Here are some details and applications of the technology.

Defining 3G

3G is also called third generation. It is named as such because it is the third generation of the standards of telecommunication hardware. It is also the general technology for mobile networking, passing the recent 2.5G. The technology is founded on the ITU or International Telecommunication Union group of standards which belongs to the IMT-2000.

3G networks allow network operators to provide users a bigger range of the latest services, as it gets bigger network capacity via heightened spectral efficiency. The included services are video calls, wide-area wireless voice telephone and broadband wireless information, all included within the mobile environment. More features included are HSPA data transmission capacities that can send data rates reaching 14.4 Mbit/s on the downlink and the uplink at 5.8 Mbit/s.

Networks

Different to the IEEE 802.11 networks, that are usually known as WLAN or Wi-Fi networks, the 3G networks cover a very wide area of cellular telephone networks that turn into incorporate high-speed internet connection and video telephony. IEEE 802.11 networks have a short range, with high-bandwidth networks mainly created and improved for data and information.

History and Start

The first 3G network offered for commercial use was launched in Japan by NTT DoCoMo. The network had the brand name FOMA and was introduced in May 2001 on a W-CDMA technology pre-release. The initial commercial launch of 3G was also done by NTT DoCoMo in Japan. This happened on October 1, 2001, although the technology was still very limited in terms of scope at the beginning. The broad availability, due to inadequate reliability had to be delayed.

SK Telecom from South Korea was the second network that was released commercially live. This was on the 1xEV-DO technology dated January 2002. In May 2002, the second 3G network from South Korea was on EV-DO by KTF, posing Koreans as the first to view the competition of all 3G operators.

Isle of Man by Manx Telcom was the first pre-commercial network released from Europe. At that time, the operator went by the name British Telecom. Telenor opened the first commercial network in Europe for business in December 2001. There were no commercial handsets, however, so there was also zero clients. These were on the W-CDMA technology.

The United States

The first 3G network in the United States that was released commercially was by Monet Mobile Networks. This was on CDMA2000 1x EV-DO technology. Later on, the network provider had to shut down operations. Verizon Wireless released the second 3G network operator in the United States in October 2003.

This was on CDMA2000 EV-DO, with a strongly growing network since. More and more countries adopted the changing technology and incorporated the use of 3G with mobile phones and handsets. Today, 3G is a very common feature among modern models and designs, with more innovations and heightened efficiency being introduced every year.
