Where 3G is Now

Where 3G is Now

Technology changes very quickly, which is why you have to be very sure about the gadgets and tools you purchase to get the most benefits. There are several generations available, as far as mobile phones are concerned. You may find that some are still very functional enough to provide for your personal and professional needs.

Here are some details about the technology and corresponding network.

The Technical Terms

Generations are defined according to their period of existence. The first kinds are 1G networks, namely C-Nets, NMT, TACS and AMPS which are categorized among the first analogue cellular systems. These began in the early periods of the 1980s.

There are radio telephone systems before these. The 2G networks, namely DAMPS, GSM and CDMAOne are the initial digital cellular systems released during the early 1990s. The 2.5G networks, CDMA2000 1x and GPRS are the improved versions of the 2G networks with information speeds moving up to 144 Kbps.

3G networks, namely UMTS TDD and UMTS FDD, CDMA2000 3x, TD-SCDMA, CDMA2000 1x EVDO, Arib WCDMA, IMT-2000 DECT and EDGE are the most recent cellular networks with data rates ranging up to 384 Kbit/s and higher. 4G is generally a marketing concept at present.

There are already studies and research being conducted to develop the 4G, although no frequencies have been assigned yet. This newest technology is expected to launch in 2012.

The International Groups

ETSI or European Telecommunications Standards Institute is functioning in Europe to improve technical standards for the UMTS. 3GPP or 3rd Generation Partnership Project is a participation between international standards groups will lead to UMTS and 3G mobile telephony technical specifications.

The starting members include TTC and ARIB from Japan, TTA of Korea, T1 (ANSI) of the United States and ETSI from Europe. The function of the groups is presented globally by the ITU or International Telecommunication Union.

ITU direct worldwide spectrum and the standardization of IMT2000, lets regional regulatory policies work together and is a framework and base for 3G combination over different technologies and regions.

The UMTS Forum shows the opinions and views of the telecommunication operators and industry. These are a mobile operator group, together with GSM Associates. European Union or EU brings together the 15 members on implementation of the UMTS.

Comparing UMTS

UMTS is quite different and unique from other 2G networks at present. It offers higher speech quality that available networks now have, in addition to speech traffic UMTS, with information services and advanced information. UMTS is advantageous compared to 2G because of its capacity to support 2 Mbit/s data speeds.

UMTS is considered as a true global system, made of both satellite and terrestrial components. The consistent service area is one of the best aspects, even when the person is roaming through the VHE or Virtual Home Environment. Users still get to have a variety of services, despite a roaming status.

Being Wideband

WCDMA is called wideband, because 3G WCDMA systems have a bandwidth of 5 MHz in a single direction. 5 MHz is not considered wide or narrow, but the bandwidth is relatively very high.

The recent 3G WCDMA systems have a bigger bandwidth compared to current 2G CDMA systems. The new 3G WCDMA systems have wider bandwidth compared to current CDMA systems. There are also commercial CDMA systems with 20 MHz bandwidth.

The Evolution of 3G

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.

Divisions of 3G

Divisions of 3G

Individuals will need to try a 3G mobile phone to know how the tools and applications work. There are several high-speed networks available today, depending on your job and personal needs. The assortment of mobile units can make it quite difficult for individuals to choose. You should understand the main types or flavors of 3G technology. The inclusions are UMTS and CDMA2000, these offer a variety of effects.

Here are some details on the technology.

The Main Types

The two main kinds of 3G include UMTS or Universal Mobile Telephone Service and CDMA2000. UMTS is being brought out over several available GSM networks. CDMA2000 takes 3G rates and speeds to the available CDMA networks. The two flavors have a couple of high-speed offshoots, voice-plus-data 1xEV-DV and data-only 1xEV-DO.

These are available in most cities, especially nations who first launched 3G technology. Speeds of the two flavors are almost the same as the regular DSL. More and more developments on faster technologies, namely 3.5G and 4G are also underway.

Individuals will need a 3G phone to determine how fast each high-speed network works. The beginning may be slow, but there are also so many available 3G handsets today from the present carriers. All mobile phones provide support for the recent 3G networks, appearing in different styles.

Knowing More About the Term

The name 3G is usually associated with mobile phone specifications and details. 3G is one, if not the most popular cellular technology available today, with several millions of people all over the globe converting. The support of the feature allows users to acquire broadband services, without having to get wired connections. You can receive the information transfer speed, beginning from 144 Kbps up to 2.4 Mbps. The 3G mobile technology is also more popularly called 3G, which is embedded in most high end models only.

Knowing More About the Kinds

UMTS is a type of 3G technology that uses Wideband Code Division Access. The term is also known as W-CDMA which stands for a certain standard. CDMA 1x EV-DO is needed to take the speed of the current 3G network to CDMA.

Individuals from all over the world can easily get the 2 kinds of 3G technology, by acquiring new handsets and starting to work on functions like sending and receiving email messages, browsing the internet and doing video conferences. You can acquire the transmission speed similarly to ADSL in the entry level.

The new models are available in a wide array of designs and colors. Some of the most popular in its class include the BlackBerry 7130e, Motorola Razor V3x and Samsung Z510.

What to Expect

With the new 3G technology, you can expect full motion videos, 3D gaming, faster online surfing and streaming music and music videos. There is also on-demand video and video conferencing with the upcoming 3.5G. If you expect 4G to come very soon, you can experience high quality streaming video and video conferencing.

Compared to older technologies like 1G, 2G and 2.5G, you can only expect to get simple features and tools like voice only or analogue capabilities, MMS, normal web browsing, ring tone downloads, basic games, short video and audio clips, push to talk features, conference calls, SMS and caller ID. The price of each technology will differ. 3G generally is pricier than previous models and platforms.

Development from 2G to 3G

Development from 2G to 3G

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.
