The Evolution of 3G

Written on November 30th, 2009 by MadChasno shouts

The Evolution of 3G

3G is beginning to be standardized because more and more users want to know whether their connectivity is within optimal range. Various tools and options are being featured by various manufacturers all over the world. Perhaps in a few years, individuals will get to experience higher capacities and better efficiency in the form of 4G. Here are some more details about the standardization and what other nations have been up to lately.

The Progression

The standardization of 3G evolution is improving in both the 3GPP2 and 3GPP. The related specifications of 3GPP2 and 3GPP developments are known as UMB and LTE, respectively. Qualcomm has cancelled developments on UMB in November 2008. 3G evolution applies a part that goes further than 3G technologies to boost the performance and functions, as well as create a smoother migration path for users.

There are various ways from 2G to 3G. The main path begins in Europe from GSM once GPRS is added to a given system. From a given point, it is possible to be directed to the UMTS system. The system evolution in North America will begin from TDMA or Time division multiple access, change to EDGE or Enhanced Data Rates for GSM Evolution or EDGE, then finally to UMTS.

The Others

A couple of 3G standards are being used and applied in Japan namely W-CDMA done by NTT DoCoMo. This is FOMA, which is attuned to UMTS, and Softbank Mobile which uses UMTS. CDMA2000, is used by KDDI. The transition for marketing reasons to 3G was finalized in Japan in 2006.

3G, when first introduced in the form of UMTS and HSDPA technology was managed by SETAR in the Caribbean, particularly Aruba in December 2007. The network’s implementation phase was brought out by Alcatel-Lucent. SETAR also implemented a 3G network founded on CDMA 1X EV-DO dated April 2007.

The Networks

Broadband internet is not the only one that can be exploited using multi-megabits speeds. VOIP and video calling can also be done. HSDPA or high speed data packet access has capacities of taking 14.4 Mbit/s downstream, which is faster compared to majority of the standard lines.

This is still faster compared to cities belonging to advanced and well-developed places. The capabilities of 5.8 Mbit/s uplink is above 10 times better than standard ADSL. It is also 7 times faster compared to the number one cable provider, Virgin Media.

Growing Networks

At present, there are about 400 3G and HSDPA networks all over the globe in one-fourth of the nations in the world. The migration of worldwide subscribers to 3G has already exceeded 15%, not to mention more than 35% among nations where 3G has been launched by the end of 2008. Several operators have launched fixed rate data plans and low cost plans for 3G information use, leading to the increase in usage and reduced costs.

During the launch of 3.5G HSDPA, the technology is given as a movable broadband modem link for both laptop and desktop users. These are priced at the low end for consumer affordability. 3G data can be quite pricey when roaming, with the average cost for every megabyte priced at around 10 dollars.

It will be very difficult to us several megabytes because of the undeveloped speeds that several networks give. You should assess and compare prices from different network providers first.

Different of Types 3G

Just as with other types of technologies, there are also different of types 3G. You can take advantage of the many features and developments by simply knowing how one type differs from the other. You can save more money by investing only in the right product that actually offers you all the right tools and applications for personal use and work.

You also need to know a bit about the existing networks to know how much speed you are actually getting.

The Types

The two main types of 3G are UMTS or Universal Mobile Telephone Service and CDMA 2000. UMTS is spread out over the present GSM networks, while CDMA2000 takes 3G speeds to CDMA networks. The two types have a couple of high-speed misses, the voice-plus-data 1xEV-DV and the data-only 1xEV-DO, which are currently available in chosen suburban regions and major cities.

More expansion is underway in the near future. The speeds for both UMTS and CDMA2000 are estimated to be about the same as a regular DSL. AT&T has also released a 3.5G speed network in 2006. This is called HSDPA, which stands for High-Speed Downlink Packet Access.

This begins at a speed of about 1.8 Mbps up to an excellent 14.4 Mbps. More devices and networks are being developed at present, introducing the 4G technology, such as WiMax.

3G Capability

To get the benefits and features of 3G technology, individuals will need a 3G phone or smartphone. The start was kind of slow, but there is now a wide array of handsets, featuring 3G technology from different carriers. All the mobiles will try to provide support for the recent 3G networks.

These appear in different styles, ranging from trendy to stylish. Some of the best examples include the Samsung SPH-M520 and LG Venus VX8800. The best 3.5G phones are supported by HSDPA phones, such as the AT&T Tilt and the LG CU720 Shine. Prices of the products will differ, depending on the available features and the brand.

The Different Technologies

Both PC and laptop users can get benefits from 3G networks for mobile broadband, excluding a Wi-Fi network. Individuals will only need a carrier-supplied PC Card. There are PC cards available for both EV-DO and HSDPA networks. Knowing the evolution will help you choose the right product and assess how much you are actually getting.

1G technology include AMPS, the speed is still very slow compared to today’s standards with voice only analogue feature. The 2G technology includes iDen, CDMA and GSM, with speeds less than 29 Kbps. Included features are the push-to-talk, voice, conference calls, caller ID and SMS.

2.5G technology includes EDGE, GPRS and 1x RTT, featuring speeds from 30 Kbps to 90 Kbps. The included features are MMS, web browsing, images, short video and audio clips, applications, ring tone downloads and games.

Recent Technologies

3G technology includes UMTS and 1xEV-DO ranging from 144 Kbps up to 2 Mbps. Some of the included features are full-motion video, quick web browsing, 3D games and streaming music.

3.5G technology includes HSDPA which is an upgrade for UMTS and 1x EV-DV, with speeds ranging from 384 Kbps up to 14.4 Mbps. Features include video conferencing and on-demand video. 4G and more features speeds from 100 Mbps up to 1 Gbps.

Some of the outstanding features include high quality video conferencing, high quality streaming video and voice-over-IP telephony.

3G Development

3G Development

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 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 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 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 Demonstrations

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.

Introduction to 3G Technology

Written on October 26th, 2009 by MadChasone shout

Introduction to 3G Technology

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.
