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 markets 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 networks 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 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 were 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.

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 is 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 3G 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 3G 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 3G 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.

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 3G. These are still currently being worked on by professionals.

There are different platforms or types of 3G technology. Each manufacturer has created and developed some of the most innovative products and mobile handsets. The CDMA2000 is one of the 3 major types. It has different features and tools also that will surely give you a whole new experience, unlike other technologies before it. Here are the details on how to make the most out of the specification.

Introduction

The CDMA2000 specification was created and developed by the Third Generation Partnership Project 2 or 3GPP2, which is a partnership that consists of 5 telecommunication standard bodies: TTC and ARIB in Japan, TTA in Korea, TIA in North America and CWTS in China. CDMA2000 has been implemented to a lot of networks as an evolutionary step from CDMAOne. CDMA2000 gives a full backward compatibility with IS-95B.

CDMA2000 is not contained only into a single IMT-2000 and, although managers have the ability to overlay ACDMA2000 1x system. The system backs 144 Kbps at present, with data rates running up to 307 Kbps in the near future, over the other present CDMAOne network.

Evolving the Technology

CDMA2000 1xEV is the other name of the evolved CDMA2000. This technology will be implemented via a number of steps, namely the 1xEV-DV and 1xEV-DO. 1xEV-DO which represents 1x Evolution Data Only. 1xEV-DV represents 1x Evolution Data and Voice. The two 1xEV CDMA2000 evolution steps will use a carrier standard 1.25 Mhz. 1xEV-DO will most likely be available for the operators CDMA2000 during 2002. The solutions for 1xEV-DV were made available in 2004.

CDMA2000 3x and CDMA2000 1x EV-DO are approved by ITU and IMT-2000 3G basics. CDMA2000 3x is a portion of what the ITU has called IMT-2000 CDMA MC or Multi Carrier. This uses a lower than 5 MHz spectrum via 3x 1.25 MHz channels to provide speeds of more than 2 Mbps.

The Technical Summary

As for the summary of the CDMA2000, the frequency band can be any type or existing and. The minimum frequency band needed for 1x is 2 x 1.25 MHz. For 3x, the required is 2 x 3.75 Mhz. Chip rate for 1x is 1.2288. For 3x, chip rate is 3.6864 Mcps. The maximum user data rate for 1x is 144 Kbps at present and 307 Kbps in the near future. As for 1xEV-DO, the max rate is 384 Kbps to 2.4 Mbps. The frame length is 5 ms, 10 ms or 20 ms. as for power control rate, it is at 800 Hz. The spreading factors are 4 256 UL.

On WCDMA

W-CDMA in 3G is known as wideband code division multiple accesses. It is one of the main technologies used for the implementation of 3G cellular systems. It is founded on the radio access method give by ETSI Alpha group with the features and specifications finalized in 1999. The implementation of W-CDMA will cover very technical details. The complexity of the systems can be seen from various angles. These include the complexity of the receiver, the complexity of the overall system and the complexity of the single algorithm.

In W-CDMA, the interface allows users of 3G to instantly send and get various data rates. UMTS networks will need the support of all current 2G services and several new services and applications. You should consider if this will be the right technique for you.

3G has provided a new way of life among mobile phone and handset users. Consumers are quickly getting on the bandwagon and investing in 3G-powered devices and tools. 3G can change the way you look at network, with the various features and effects. You can get ahead and take advantage of the highest details and gadgets by understanding the functions and uses of the system, as well as the available networks. Here are more details.

Higher Speed

With 3G technology, you get to enjoy data transmission speed leading up to 2Mbps, considering that you have a phone in stationary mode. It also gives you high degree of connectivity and higher networking, plus resistance to noise.

The technology has enhanced the bit rate, allowing service providers to give high speed internet facilities, higher call volumes and host of the multimedia applications that can be given to the customers. All the services can be given to the customers based on the data quantity transmitted and not on the time used for the service. The services rendered to clients are cheaper overall.

On Price

Despite the new speeds and features of 3G technology, the prices of handsets and mobile units are relatively the same. The most recent models, however, may be priced higher compared to those featuring 2.5G. You can avail of discounts and other promos by visiting web sites and other private sellers on the market.

3G services for mobile devices have been introduced by various handset creators and cellular carriers. The companies, however, are not very good at explaining the exact details, except for a given few. There seems to be a missing link between the current standard from previous services provided by 2.5G or 2G technology. Knowing the types and details will help you pick the right tools for your personal use or business. Here are some features.

About 3G

3G cellular technology is defined as the provision of wireless broadband data and information services right to a person's mobile unit. Compared to the previous technologies, 3G promises speeds ranging from 144 Kbps, which is 3 times faster compared to the traditional 56K dial-up modem connection up to 2.4 Mbps, which is very near cable-modem speed. The networks of 3G allows you to browse quickly through web pages, watch on-demand video programs, download and play music, videos and 3D games, watch streaming videos and music videos and have a video conference with others located on the other side of the plant.

More Developments

The HSDPA is a new technology, which may also be called 3.5G, coming very soon. This offers fasters speeds of up to 7.2 Mbps and also promises the likes of 14.4 Mbps very soon. The interface is very much different on a cellular phone, but other experiences like downloading; streaming, web browsing and sending messages and email can be very comparable to a computer broadband connection.

As of the present, there are 3 big carriers that introduced and launched 3G services. There is also a wide array of 3G-enabled handsets now. In early 2005, Verizon Wireless first marketed the devices. Sprint and Cingular followed soon after. Cingular is now known as AT&T. T-Mobile is also joining the pack as it introduces its new 3G network in 2008.

The Accesses

Currently, 3G technology is the most recent in mobile communications. 3G is the shorter term for third generation, making analogue cellular technology generation one and digital/PCS generation two. The 3G technology is planned and devised for the real multimedia cellular phone, also known as smart phones. These tools feature higher bandwidths and transfer rates to cater to web-based applications and phone-based video and audio data files.

The most common include CDMA2000, which is based on code division multiple access, TD-SCDMA, which stands for Time-division Synchronous Code-division Multiple Access and WCDMA or UMTS which stands for Wideband Code Division Multiple Access.

The Networks

3G networks have the capability of transferring speeds up to 3 Mbps which is equivalent to around 15 seconds for every download of a 3-minute MP3 song. To compare, the speediest 3G cellular phones can move speeds up to 144 Kbps, which is equivalent to around 8 minutes to download a 3-minute MP3 song. The high data rates of 3G are recommended when downloading or acquiring information online, as well as sending and receiving huge multimedia files.

3G phones are comparable to small laptops that can cater to several broadband applications like browsing the internet, receiving streaming videos online, video conferencing and sending and receiving faxes. The soaring towers are among the most important element of the group, allowing the data to be transferred from one hone to another. 3G basically is a cellular phone network protocol.

You can get more info about smartphones by visiting the manufacturer web site.

Before you decide to upgrade your current gadget and start investing on 3G technologies, you have to learn how to weigh the advantages and disadvantages first. There are several features to consider to ensure that you are getting the most out of your money. Price can become an issue, as well as the service providers since speeds can become unreliable at times if you do not understand the standard. Here are some tips to get you started.

Why You Need a Unit

First, you have to consider your reasons for investing in 3G technology. Do you usually make video calls to individuals from the other side of the planet? Are you very well equipped in terms of financial support and know-how on the new technology to use it to its optimum potential? Do you feel as if your current gadget no longer serves the purpose efficiently?

These are just some of the considerations if you plan to buy a new 3G unit. Take note that some of these devices can cost several hundreds of dollars, depending on the design and manufacturer. If you are not quite familiar with 2G or earlier models, you may be better off delaying the option until you have expanded your knowledge on its many uses.

Finding the Sources

There are several places where you can purchase the latest 3G gadgets. You have to study the background and visions of each given manufacturer first to know whether their virtues and goals coincide with your own needs and personal requirements. You can visit the official web sites of the biggest names and companies to determine the most recent models, and if there are other add-ons and tools available.

You can also rely on these sources to get excellent prices. Some of the best products available can be seen on the internet. You should take time to study the features and special characteristics of each gadget, to determine if it is the right one that suits your business and personal requirements. You can also talk to local dealers and consider other aspects like warranty, service providers and connectivity.

On Service Providers

There are now several service providers for 3G all over the world. You can find out more about the services and offers of each by calling or visiting their company web site. Determine the type of technology and platform that you are using and check how well you can take advantage of the given aspects and features. Among the many service providers, you should also check if they guarantee clear and crisp connectivity consistently, regardless of the time and location of the customer.

A good 3G service provider should have a customer center and hotline, wherein you can immediately call if ever you need assistance about any given tool. You should also be given manual and other types of help when it comes to connectivity. You should know the standard speed, so that you can compare how much you are currently getting and using up against the speeds that you expect and paid for.

How to Use 3G

Take note of the important aspects of 3G, such as speed, connectivity and accessibility. You should expect to enjoy several features and functions like downloading videos and music, video calling or talking to a friend without any communication problems for several hours or minutes and accessibility to information and data over the internet.

You can check your web site, read and send email and get the latest news coverage no matter where you are and what time it is.

3G technology is the most recent released for mobile phones. More and more individuals all over the globe are converting to the new platforms because of faster connectivity, easier accessibility and better performance overall. You can enjoy faster downloads and viewing for music and videos, play 3D games and do video conferences with others. Here are more details about the compatibility among networks and how well you can get ahead.

Compatibility with Other Networks

UMTS networks can be managed and operated using GPRS or GSM networks. The systems will apply a number of frequency bands, so that mobiles and BTSs will not interfere with one another. Some vendors will claim their core network as UMTS compatible, such as RNC, BSC, MSC, SGSN and HLR, although several operators will choose to create an entirely independent and unique UMTS network. A number of the most recent GSM BTSs can also have parts of the UMTS radio and share a single rack.

The UMTS specifications are created, leaving maximum compatibility between UMTS and GSM systems. During the late 2002, there are also multi and dual band phones that can be applied in UMTS and GSM networks. Over time, the phones will have the capacity to do handovers from one network to another.

The Transition

There may not be a transition time from UMTS up to the current system, since the systems of GSM will continue to function constantly in the next 10 years. A number of 1G networks are actually still functional and running until this time in some areas of the world. The only limitations for operators are the terms of the GSM license and the personal preferences of clients. The networks of UMTS will be given as an addition to the mobile platform.

Licensing and Status

Most GSM operators failed or missed to obtain a UMTS license, such as Denmark, France and the United Kingdom. These are not totally counted out. Current operators have big assets, a huge customer base, retail network, BTS site locations, image, transmission systems and several others. These give them the advantage of making deals with license holders of 3G technology. Some of the best examples are Telia with Tele2 in Sweden and Hutchison 3G in the UK.

In the United States, a number of operators have chosen CDMAOne, CDMA2000 1x EV-DO, CDMA2000 and CDMA2000 3X. Others have even chosen GSM1900, EDGE or D-AMPD-EDGE. There are new cellular frequencies allocations that may have been delayed or postponed, leading operators to use the current frequencies that naturally stop the available capacity at a certain point.

Other Details

The TD-SCDMA 3G system has been constantly tested in China. There is license allocation and the possibility to adapt to other 3G technologies. When 3G licenses are given out or issued, the Beauty Contest term may be used. This means that the government will require every applicant to give a plan on how they intend to build a network and manage other business regarding 3G.

There are several aspects to consider when planning, such as asking how many jobs can be made, how many domestic products are consumed, what kind of plan in terms of financing will lead to success, what type of services can be availed of and how other less fortunate areas can also take advantage of 3G technology.

Nowadays, people all over the world can enjoy the benefits of 3G technology. Just a few years back, 2G was the norm, and before that, more "crude" processes of accessibility and the like. The networks have evolved significantly, as the largest nations of the world work nonstop to continue to deliver the best services to consumers. You can learn more about the process by checking how 2G technology moved on to 3G. Here are the details.

The 2G Network

Initially, 2G networks were created mainly for slow transmission and voice data. Because of the quick changes in the expectations of users, these no longer meet the requirements today in terms of wireless connection. The movement and evolution from 2G to 3G technology can be divided into several phases, namely GPRS, EDGE and pure 3G.

On GPRS

The first big step in the move to 3G happened through the launching and launching of General Packet Radio Service or GPRS. The cellular services, mixed with GPRS resulted to 2.5G. GPRS was capable of giving data rates ranging from 56 kbit/s up to a maximum of 114 kbit/s. This can be used for services like WAP or Wireless Application Protocol access, MMS or Multimedia Messaging Service, SMS or Short Message Service and internet communication services like World Wide Web access and email.

The data transfer of GPRS is usually charged for each megabyte of traffic being transferred, while the data communication via the usual circuit switching is charged by the minute of connection period, regardless of whether the consumer actually used the capability or is just in idle mode.

GPRS is a top-effort packet switched service, compared to circuit switching, where there is a given QoS or Quality of Service is certified during the connection for non-mobile users. It gives medium speed data transfer, via the use of idle Time division multiple access or TDMA channels. Before, there used to be some believe to stretch GPRS to take over other standards. Instead, the networks are usually changed to use the standard of GSM, making GSM the new release. The original standard was conducted by the ETSI or European Telecommunications Standards Institute, but is now the 3GPP or 3rd Generation Partnership Project.

The EDGE

The GPRS networks have changed significantly to EDGE networks, through the presentation of 8PSK encoding. Enhanced information rates for EDGE or GSM Evolution, IMT Single Carrier or IMT-SC and Enhanced GPRS is a reverse-compatible digital mobile phone technology, allowing improved data transmission rates, as an extension over the standard GSM. EDGE can be counted as a 3G radio technology, involved in ITU's 3G description, but is usually frequently referred to as 2.75G. EDGE was launched on GSM networks, starting in 2003, by Cingular now at the start in the United States.

Standardization

3GPP standardized EDGE as it belonged in the GSM group. It is considered as an upgrade that gives a potential 3-fold boost in the capacity of GPRS and GSM networks. The specification gets bigger data rates by altering to very sophisticated processes of coding, particularly 8PSK, inside the GSM timeslots. EDGE can be applied in various packet switched applications, like the internet, other multimedia and video.

Pure 3G is the introduction of UMTS technology and networks from EDGE networks. As of the present, more work on the development of the 4G is still underway.

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.

Spreading More

Turkey auctioned 4 IMT 2000/UMTS standard 3G 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 3G technology in Africa. EMTEL in Mauritius launched the first commercial 3G 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 provide 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 3G 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 3G, which are expected to meet the expectations of consumers with broadband speed. Industry sources recommend that 3G 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 3G network availability and EDGE have separate functionality.

Standardizing the Network

The ITU or International Telecommunication 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 transferring over IP/RTP and ATM/AAL2.
