Understanding WCDMA

Posted by admin | Posted in 3G | Posted on 26-08-2009

3G technology also comes in various forms and platforms. Understanding the

major ones will help you decide which one is the right tool. You should

also tell the technical details, to know if you are getting the right kind

of efficiency and accessibility. Getting information from the internet

other various sources will never be as convenient as fast, since 3G is the

newest available. There are new developments and changes as well to get you

ahead.

Knowing WCDMA or UMTS

W-CDMA wideband code-division multiple-access is among the major

technologies that implement the 3G or third generation cellular systems.

This is founded on the radio access technique suggested by the ETSI Alpha

Group. The details and specifications were finalized in 1999. The

implementation of W-CDMA is going to be a technical challenge due to the

complexity and versatility. The sophistication of the of the systems of

W-CDMA can be seen from various aspects.

These are namely the complexity of the overall system, computation

complexity of the receiver and the complexity of ever single algorithm.

W-CDMA link-level simulations or more than 10 times the compute intensive

compared to 2G simulations. In the interface of W-CDMA, the different

interface users can immediately transmit at varying information rates, with

the data rates even varying in time. Networks of the UMTS are required to

support every 2G service, plus new services and applications.

The Technical Details

As for the FDD technical summary, the frequency band will range from 1920

MHz up to 1980 MHz and 2110 MHz and 2170 MHz or frequency division duplex.

The minimum frequency band needed is 2 x 5 MHz. The frequency re-use is 1.

Carrier spacing is between 4.4 MHz and 5.2 MHz. The most number of voice

channels on 2 x 5 MHz is 96 with a spreading factor of 256 UL and AMR or

7.95 Kbps and 98 with a spreading factor of 128 UL and AMR of 12.2 Kbps.

Other Specs

The voice coding includes AMR codecs ranging from 4.75 kHz up to 12.2 kHz,

GSM EFR is at 12.2 kHz. SID is also included at 1.8 kHz. The channel coding

includes convolutional coding with turbo code for high rate data. The

duplexer required is 190 MHz separation with asymmetric connection

supported. Tx and Rx isolation is MS:55db and BS:80dB. The Receiver is

Rake, while receiver sensitivity is Node B.

More Information

Data type for the device is packet and circuit switch. Modulation is QPSK

and pulse shaping is root raised cosine, rolling off at 0.22. The chip rate

is 3.84 Mcps while the channel raster is 200 kHz. Maximum user data rate on

the physical channel is 2.3 Mbps with a spreading factor of 4, and parallel

codes of 3 DL / 6 UL, with limited interference. HSPDA will provide data

speeds going as fast as 8 to 10 Mps and 20 Mbps for MIMO systems. The

channel it rate is 5.67 Mbps with a frame length of 10 ms or 38400 chips.

There are 15 slots or frames, and 2560 chips. Handovers are soft and

softer, plus a hard interfrequency. The power control period has a time

slot with a rate of 1500 Hz. Power control step size is 0.5, 1, 1.5 and 2

dB while power control range is UL 80 dB and DL at 30 dB.

The Several Uses of 3G

Posted by admin | Posted in 3G | Posted on 23-08-2009

3G is already embraced by thousands of individuals all around the globe.

You can take advantage by assessing the various features and rates first.

There are several tools and equipment that incorporate the features and

functions of 3G. You may want to know the added uses when going roaming and

the like. Here are some vital information on how 3G has spread to the

biggest nations of the world, as well as placed itself in smaller areas

too.

A New Level of Broadband

In the United Kingdom, the mobile network Three or 3 presents that 90% of

the total population in the nation uses and applies 3G, not to mention 99%

having the standard text and talk network which includes 2G, 2.5G and EDGE.

As expected, you can get a minimum of 2 Mbit/s if you are stationary or

only walking slowly. However, speeds will begin to fall as you gain more

movement, such as riding a car running at average city speed.

3G networks in Great Britain will provide you several packages. The package

can run up from 1.8 Mbit/s on networks like T-Mobile and increase up to the

likes of 7.2 Mbit/s. This is the similar speed as a fixed line given a few

hundred meters from the possible exchange in city areas of London that

takes the entire concept as quick easy mobile broadband to a new and

different level.

Anticipations

The packages offered by service providers may not be the same or sustained

7.2 Mbit/s. Typically, 3GB or 3072 megabytes that is included in a given

plan can cost you anywhere between $25 to $50 each month. Three or 3 is

offering 15GB at around $50 to $60 each month, or at half the price if you

already have an existing plan with the company. Three will not provide

headline speeds, however, as fast as the one provided by Vodafone.

3G is still considered as a baby, with high prices being expected due to

the high fees for frequency licensing. The basic expenses of getting

several teams of engineers to start a nationwide network and maintenance

can be quite high. Canada, shows some of the biggest data access fees in

the world available to subscribers. The absence of a data agreement with

1KB of data can be priced at $0.05, converting into $50 for every megabyte

used on the GSM providers Rogers and Fido in Canada. The creation of a 4G

network is under works, which is capable of providing speeds of up to 100

Mbit/s for mobile users and up to 1 Gbit/s when stationary.

For Security

3G provides you the a bigger degree of security compared to 2G

predecessors. It allows the UE to authenticate the network that it is

connected to, the consumer can be certain that the network is the right one

and not impersonated. 3G networks apply the KASUMI block crypto, aside from

the older A5/1 stream cipher. Several serious weaknesses in the KASUMI

cipher have been pointed out, however. End to end security is provided

aside from the 3G network infrastructure security, when frameworks of

applications like IMS are connected to, although this is not usually a

property of 3G.

Some Issues

3G is successfully introduced to consumers all over the globe, with a

number of issues being argued by both users and providers. Expensive input

fees for the licenses and agreements can be given, as well as several

differences in the licensing terms. There is also the extra expense of

acquiring advanced 3G mobile units and the lack of buy-in by 2G mobile

consumers in exchange for the new wireless services of 3G.

The Divisions of 3G

Posted by admin | Posted in 3G | Posted on 17-08-2009

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

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.

Starting the Smartphone and 3G

Posted by admin | Posted in body language | Posted on 14-08-2009

Smartphones were introduced just a few years ago, and are now considered as

a staple device in 3G among individuals from all over the globe. There are

several features and applications that you have to know about to invest in

the right product. There are so many gadgets now available in stores and

web sites. Prices will vary depending on the brand, tools and manufacturer.

Here are more details about the smartphone.

Describing the Phone

A smartphone is a mobile phone unit that provides advanced and modern

capabilities, usually with PC-like functions. The smartphone has no

industry standard definition. For a number of people, a smartphone is a

cellular unit that operates a full operating system software, giving a

standard platform and interface for developers of applications.

For other people, a smartphone is just a regular cellular phone with very

modern features such as the internet, email and ebook reader capacities.

There are also other features such as external USB keyboard, a built-in

full keyboard and VGA connector. It is simply a small computer with a 3G

phone capacity. The rest of the mobile phone market has been outgrown by

smartphones. These gadgets have big screens, open operating systems,

powerful processors and abundant memories.

Agreements in the Industry

There is truly no real meaning or definition of the smartphone in the

industry. The descriptions have changed significantly over time.

Smartphones according to a number of experts are a lot different from

regular mobile units in a couple of basic ways, namely what these can do

and how these are built. Other meanings apply various stresses on the two

factors.

As far as smartphones are concerned, it is only a matter of evolving from

one phone to the most recent. The real device at a certain period may even

become smaller in size, thereby losing its essence or being as a phone. The

device might be referred to as integrated. The device may be considered as

invisible as possible between the things the consumer has and what he or

she wants to do.

The Operating System

A lot of devices that consider smartphones at present use a very

identifiable operating system, usually with the capacity to add

applications for the purposes of entertainment, enhanced data processing

and connectivity. These are significantly better compared to regular phones

that only support starter applications such as Java games. The 3G

smartphone applications may be enhanced by the creators of the tool, via

the network operator or by other software developers from the third party,

because the operating system is open.

On the Features

In the case of features, a lot of smartphones back up full featured email

capacities having the functionality of a full personal organizer. Other

functionalities may involve an added interface like a small QWERTY

keyboard, a built-in camera, a D-pad or touch screen, an accelerometer,

contact management, the capacity to read business documents in different

formats like Microsoft Office and PDF, a touch screen or a D-pad, media

software for playing music, viewing video clips and photos, internet

browsers and even just safe access to company mail.

A basic feature among many 3G smartphones is a contact list with the

ability to keep as many contacts as possible that the memory permits,

compared to standard phones with a limit to the highest number of contacts

that can be kept.

Smartphone and 3G Stories

Posted by admin | Posted in 3G | Posted on 11-08-2009

The smartphone and 3G has evolved dramatically in just a few short years,

which is why more and more people from all over the world are converting to

the new technology. You should know the difference between units and models

to get the most advantages, in terms of tools and applications. You can get

ahead by learning more about the manufacturer and other advanced features

that will function effectively for work and personal use.

The First Smartphone

The very first smartphone was known as Simon, which was created and styled

by IBM in 1992 and presented as a concept product at COMDEX. COMDEX is the

computer industry trade show held in Las Vegas, Nevada. This was shown and

launched to the public in 1993 and sold by BellSouth. Aside from being a

mobile phone, Simon also featured a world clock, note pad, email,

calculator, calendar, send and receive fax and games.

There are no physical buttons that allow you to dial. The customers,

instead, use a touch screen to choose phone numbers with a finger or make

memos and facsimiles with an optional stylus. Text was written via a unique

on-screen predictive keyboard. As of the present standards, Simon becomes a

low-end product. The feature at the time, however, was very modern.

The Nokia Age

Nokia released its first set of smartphones, beginning with the Nokia

Communicator line. The Nokia 9000 was the first of the bunch, launched in

1996. The unique palmtop computer type smartphone was borne out of a

combined effort of an early successful and pricey PDA model created by

Hewlett Packard, plus Nokia’s bestselling phone at the same time. The early

prototype models featured both devices organized using a hinge.

The Nokia 9210 was the first color screen Communicator type that was

considered as a real smartphone, with an open operating system. The 9500

Communicator was the first camera phone Communicator and Nokia’s very first

WiFi phone. The 9300 Communicator is the 3-dimensional alternation into a

smaller form factor.

The recent E90 Communicator involves GPS too. The Nokia Communicator model

is outstanding and is the most expensive model sold by a main brand for

almost the full lifespan of the series of models, immediately 20% and

occasionally 40% pricier compared to the next most expensive smartphone

featured by other major manufacturers.

More Devices

One of the devices described and sold as a smartphone was Ericsson R380.

It, however, cannot run native third-party applications. Even though Nokia

9210 is one of the very first true smartphones having an operating system,

Nokia still constantly refer to it as a Communicator. RIM launched and

released the first BlackBerry in 2001. It was defined as the first

smartphone enhanced for wireless email use, achieving over 8 million

customers in just a few years. Three-fourth of the total belong to North

America.

More Nokia Releases

The Nokia 7650 was announced in 2001, and was referred to as a smart phone

in the media. The Nokia support site also refers to it as a smartphone. The

press release, however, refers to it as an imaging phone. Handspring also

presented the first widely famous smartphone tools and gadgets in the

United States by joining a GSM phone module with Palm OS based Visor PDA.

Nokia launched the N-series of 3G smartphones in 2005. These were marketed

as multimedia computers, instead of mobile phones.

Knowing the Different 3G Types

Posted by admin | Posted in 3G | Posted on 08-08-2009

3G, just like other types of technologies also come in various kinds. You

can take advantage of the many features and developments by simply knowing

how one type differ 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.

3-G 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.

Getting to Know 3G Development

Posted by admin | Posted in body language | Posted on 05-08-2009

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.

Compatibility Discussions with 3G

Posted by admin | Posted in 3G | Posted on 02-08-2009

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.
