3G used to be a lot less powerful in terms of coverage and efficiency a few years back. Some of the biggest nations of the world introduced and launched initial models, then continued to develop the details to further cater to the needs of consumers all over the world. There are approximately 3 billion mobile subscribers in the world, with 3G starting to take a big piece of the pie. Here are some more information about the growth.

Turkey auctioned 4 IMT 2000/UMTS standard 3 G licenses with 25, 35, 40 and 45 MHz top frequencies in November 2009. With the 358-million euro offer by Turkcell, it has availed of the 45 MHz band, followed by Avea and Vodafone leasing the 35 and 40 MHz respectively for 2 decades. The only one available for auction at present is the license for the 25 MHz top frequency. 

A 3G video call created from Johannesburg, South Africa via the Vodacom network in November 2004 was the very first use of 3 G technology in Africa. EMTEL in Mauritius launched the first commercial 3 G in Africa via the W-CDMA standard. In March 2006, a 3G service was given by the emerging company Wana in North African Morocco.  3G HSDPA services was implemented by Rogers Wireless in Eastern Canada as early as 2007 via Rogers Vision. Fido Solutions and Rogers Wireless currently provides 3G service in several urban centers. 

Rates of Data

The ITU has not yet given a concrete description of the data rate that consumers can get from 3G providers or equipment and tools. The consumers who were given 3 G service may not clearly point out a suitable standard, indicating that the rate given are met adequately. In a commentary, it was stated that the expectation for IMT-2000 will give higher rates of transmission, having a minimum speed of 2Mbit/s and the highest at 14.4 Mbit/s for stationary consumers. 348 kbit/s can be expected in a moving vehicle. 

The ITU does not specifically indicates a minimum or average rates or the modes of the interfaces that can be considered as 3G technology, so different rates are offered and sold as 3 G, which are expected to meet the expectations of consumers with broadband speed. Industry sources recommend that 3 G can give  384 kbit/s at or lower than pedestrian speeds, with only 128 kbit/s inside a moving vehicle. Although EDGE is included in the 3G standard, a number of phones say that 3 G network availability and EDGE have separate functionality.

Standardizing the Network

The ITU or International Telecommuncation Union described the demands for 3G mobile networks, using the IMT-2000 standard. The 3GPP or 3rd Generation Partnership Project is a group that continues to work by describing a mobile system that meets the standard of IMT-2000. The system is known as UMTS or Universal Mobile Telecommunications System. 

There are 6 radio interfaces in IMT-2000 namely, W-CDMA or UMTS, CDMA2000, UWC which is implemented frequently with EDGE, TD-CDMA/TD-SCDMA, DECT and Mobile WiMAX. 

On Advantages

UMTS is based on layered services, apart from GSM. The top of the line is the services layer, which gives quick deployment of services, plus a centralized place. At the center is the control layer, which supports the upgrade of processes and provides the capability of the network to be allocated in a dynamic manner.

At the bottom line is the connectivity layer, wherein any type of transmission technology can be applied, with the voice traffic transfering over IP/RTP and ATM/AAL2.

3G was successfully launched and introduced to millions of consumers all over the globe. However, there are still some features and uses that are still questioned by many. Knowing the effects and details will help you take advantage of aspects like price, functions and accessibility. Here are some more information regarding the full uses of 3G technology.

Some Concerns

Some of the concerns between users and consumers are the pricey fees of input given for the 3 G service agreements and service licenses. Expense of 3G phones are also currently on the rise, as more and more people are becoming aware of the advantages in terms of speed and connectivity. There is a big amount of debt at present sustained by various telecommunication companies, making it a very huge challenge to create the important infrastructure for 3 G technology. There are also several differences in the terms of the license. 

There may also be lack of member state support for financially challenged operators. There can be inadequate buy-in by 2G mobile users for the new services of 3G wireless. The prices of 3G mobile services in various nations can be very high, which includes access to the internet. There is also inadequacy of users required for 3G voice and data services in a handset or mobile device. 

More Uses

3G is the most recent wireless technology available, although there are now plans immediately of using 4G. The technology is also popular as UMTS or Universal Mobile Telecommunications System, which is a progress over 2G or second generation. This provides wireless access to information and data to consumers from all areas of the world and at different times and dates. 

This is the latest mobile technology and is described as a generic name for mobile technology host. 3G cellular phones are the very first released in Japan in October 2001. The 3 G phone was created and designed for users to have the ability to surf the internet, watch movies, download songs and videos and view pictures of other individuals that they are in contact with. 

Some Benefits

You can perform all the functions in a 3G phone, as you would normally do with your current mobile device. The speed, efficiency and connectivity will be better than before, however. 3G technology offers you faster connectivity, music entertainment with the best quality and faster internet access. The advantages are so many so you can easily get other benefits like quick and easy video calling, video call facility, clearer communication experiences and faster speeds when the two parties are using 3G technology.

Accessibility

Because of easy and fast accessibility, you get to enjoy data transmission speed up to a maximum of 2 Mbps, if the individual is using the cellular phone on stationary phone. This also gives bigger and faster data transfer rates of increased networking and connectivity. On top of it all, you get to enjoy noise resistance. 

The technology has increased bit rate that allows service providers to give high speed internet facilities, host of the multimedia applications to customers and heightened call volumes. The prices of units will differ, depending on the features and service provider. When you are in a moving vehicle, expect to have slower speeds than usual.

There are also greater potentials for the uses of 3 G. These are still currently being worked on by professionals.

Although 3 G 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 3 G 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 3 G 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 Three G, 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 Three G clients together with CDMA 2000 1x RTT. Via the definition, the total 3 G 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 3 G 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 3 G networks will be given to China Mobile, the biggest mobile operator. The telecommunications sector in the country has been re-organized.
