3GRead People Like A Book

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.

There are several systems developed for 3G technology, which explains why

people should be more aware about the changes and details of their new

gadgets. 3G devices can cost a lot of money, so you should learn how to

check the specs and platforms first if these work very well for your

personal functions and work. UMTS is one of the most common systems. You

will find that it is also one of the most ideal to use if ever you choose

to invest.

Defining UMTS

UMTS stands for Universal Mobile Telephone System. It is one of the 3G or

third generation mobile systems created and developed inside the framework

of the ITU IMT-2000. It presents the new generation of broadband

multi-media mobile telecommunications technology. The area covered by

service providers will be on a global scale, through the FLMTS type or

Future Land Mobile Telecommunications Services.

This is now known as IMT2000. The coverage will be given through a mixture

of cell sizes starting from in-building Pico Cells to the satellite Global

Cells. These provide services to the far areas of the globe. The UMTS is

not an alternative of 2G or second generation technologies like DCS1800,

GSM and CDMA that constantly changes to their optimum potential.

The Various Kinds

There are several networks types featured by 3G technology. ITU suggestion

ITU-R M.1457 indicates 5 kinds of 3G radio interfaces. Inclusions are the

IMT-2000 DECT assisted by the DECT forum, the IMT-2000 TDMA Single Carrier,

which is also called UWC-136 or Edge, assisted by UWCC, the IMT-2000 CDMA

that spreads directly, also called UTRA FDD which includes WCDMA in Japan.

UMTS is developed by 3GPP, IMT-20000 CDMA, also called CDMA2000 3x

developed by 3GPP and IMT-2000 CDMA TDD which is also called UTRA TDD and

TD-SCDMA.

The Core Networks

There are various types of 3G core networks. The group IMT-2000 of 3G

systems involves 3 kinds of core network technology. The first one is the

Internet Protocol based in the future to be specific, the GSM based

protocols over SS7 protocols for signalling and the ANSI-41 based or IS-634

protocols for sending signals.

CDMA2000 and UMTS Comparison

If you want to compare UMTS and CDMA2000, you can begin by telling their

origins. Both were developed individuals and are separate 3G standards

approved by ITU. CDMA2000 1xRT and future CDMA2000 3x were enhanced to be

backward compatible with CDMA One. The two 1x types are similar in terms of

bandwidth and chip rate. Successful deployment in America requires backward

compatibility. UMTS was enhanced primarily for nations having GSM networks.

These prime countries are prioritized, since they agree to free new

frequency ranges for the networks of UMTS. The benefit is that there are a

lot of new capacities for operators because of the new range of frequency.

3GPP manages the standard development and keeps the core network very close

to GSM network as much as possible.

Compatibility

UMTS cellular phone units are not intended to be backward compatible with

the systems of GSM. There are two flavors available for UMTS, namely FDD

and TDD. FDD is implemented first. There are also a number of

harmonizations done between the systems, such as pilot issues and chip

rate. Always consider your intended functions and level of experience

before choosing the right kind to buy and use.

3G, just like other types of technology, also comes in various kinds and

platforms. Depending on the model, the speed, capacity and overall feature

will also differ. Customers will have to pay more for very advanced

designs, complete with the important functions. Some of the top

manufacturers and investors have poured in a lot of effort and money just

to create the right components that will best suit consumers all over the

world.

On Freescale

Freescale features a wide range of platforms on the cellular level,

complete with components that will match the time-to-market and minimal

cost requirements of ODMs and OEMs. There is opening operating system

support which also includes S60, Microsoft Windows Mobile, Symbian and

Linux. One-core modem architecture applies software to isolate modem and

other applications on hardware that is shared. This significantly minimizes

sophistication and simplifies the software development and speed time to

market by around 6 months.

Features and Products

The world-class security in software and hardware for secure transactions

is also featured. Freescale also has low power style that incorporates

sophisticated techniques like dynamic voltage scaling, low leakage process

for optimum usage time and clock gating. There is reduced component

quantity for sleek, slim and modern styled handsets.

Some of the products available include the MXC300-30 and MXC275-30. The

300-30 is a lone core modem platform of 3G which is used mainly for EDGE,

GSM, GPRS, HSPA and UMTS/WCDMA. The MX275-30 is a 2.75 one-core modem

platform that is mainly used for EDGE Type 12, GSM and GPRS.

The Technologies

The MXC300-30 boasts of the MXC one-core modem architecture, the LTE that

will send desktop information rates to cellular tools and devices and the

HSPA for quick 3G speeds immediately. The MXC300-30 is the initial platform

that has the 3G single core modem. The single core processor located at the

center mixes the StarCore SC140e Digital Signal Processor or DSP that

functions at a maximum of 250 MHz and a processor core, ARM1136 that

functions up to 532 MHz. The single core modem manages all signalling

protocol layers L1, L2 and L3 for 3G, 2.5G and 2.75G standards, involving

the Global System for Mobile Communications (GSM), EDGE or Enhanced Data

for GSM, GPRS or General Packet Radio Service and WCDMA or wideband code

division multiple access.

Features

The device features the StarCore SC140 DSP with a speed maximizing at 250

MHz. It also has an ARM11 applications processor with a maximum speed of

532 MHz. Other features include Quad-band GSM 850/900/1800/1900 MHz and

WCDMA tri-band 850/1900/2100 MHz. HSDPA has 3.6 Mbps. There is also an

optimization for open operating systems such as Symbian and Linux,

excluding the addition of any accelerator or processor.

There is a single antenna interference that cancels the GMSK or Gaussian

minimum shift keying. Wireless connectivity features include the Bluetooth

interface support, wireless local area network or WLAN and Digital Video

Broadcasting-Handhelds or DVB-H interface support. The features are fairly

similar to others that are also sold in the same class.

The Device

You can learn more about other available powerful tools and devices on the

internet and by visiting telecommunications shops and service providers.

Find out more about the important features and how these can work well with

your lifestyle and occupation. Price will vary, depending on the included

features and tools.

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.

There are several networks available when using various types of 3G

accessories and gadgets. You have to consider the details and different

data speeds, to understand and know if you are getting enough for your

money. You can learn more about networks by visiting their respective web

sites or companies. You should know which brands are leading and which ones

still need some improvement. Here are some more details.

Turn Key 3G Network

No network vendor can provide all components and equipment to the full 3G

network. There are a limited number of individuals considered as a main

contractor to create a turn-key 3G network. Normally, network vendors can

bring partners like applications providers and service, civil work, handset

manufacturers and acquisition industries.

The current short list of major vendors for the UMTS networks considered as

turn-key are Alcatel, Lucent, Ericsson, Motorola, Nokia, Nortel and NEC or

Siemens. The present short list of main vendors for CDMA2000 networks

categorized as turn-key include LG Electronics, Lucent, Ericsson, Motorola,

Samsung and Nortel.

Costs of the Network

A 3G network can be built for a certain price. You can get more information

by reading annual reports and contract announcements. These will indicate

the sum of money that operators will spend on buildings and infrastructure.

In each nation, a carrier will need to spend about the same costs to create

a 3G network of the same size. All operators generally spend the same

amount of money for every subscriber.

Spending details will include services such as integration, logistics,

planning, commissioning, testing and many more. Press reports present that

operators in Europe spend about 650 euro for every 3G subscriber for site

civil works, infrastructure and planning services. The figure are expected

to get lower in a few years. There are several other fees to consider also,

like licensing.

Ensuring Safety

On electromagnetic radiation safety, you have to go to the latest

government EMR or standard or electromagnetic radiation. You may also check

and review the government web site. The government pages should contain

more data and information. You can get a booklet that provides guidelines

including details like, the safety zone around the transmission and mobile

antennas, local guidelines on the location of the antenna, the combined

radiation field values computed from various antennas on a single rooftop,

how the EMR computations are made and power levels of interior antennas.

More on EMR

The government frequently do not indicate the right values that are safe or

unsafe, for legitimate reasons. EU nations usually issue a number of steps

or guidelines that are considered quite rough compared to the standards

given by the EU. The American FDA has a clear statement too. There are more

than 700 studies and tests related to EMR without a real known outcome. You

should consider the risks and potential threats associated with the

continuous development of the 3G technology, and others more powerful than

it.

Base Stations

There are many factors to consider, to check if base stations are required

for a network for UMTS. Some inclusions are financial support for the

network build, economical factor to create sites, required coverage areas

related to a license agreement, design preferences of company experience to

implement the provided plan, coverage requirement for clients and amount of

frequencies that the available carriers have.

Since 3G is a very new technology, it is easy to expect that there are some

drawbacks as well. More and more developments are being conducted by

various manufacturers worldwide, to better cater to the needs of consumers.

You can take advantage by getting to know your gadgets and tools from the

inside out. Here are some details on the possible consequences and if you

should consider getting your own 3G mobile unit.

Some Backfires

Some devices, particularly the iPhone 3G, has no instant messaging options

or MMS. You then take out the advantage of sending and receiving photos via

MMS. There is inadequate or missing expandable memory too. A number of

devices may appear in a couple of variants, namely the 8 and 16 GB built-in

memory.

The non-detachable battery also is a disadvantage, since you have to put

two and two together to get the needed energy. There are also limited

service provider selections, so you do not get to pick your personal ISP.

Instead it is taken and sold via a certain MSP Mobile Service Provider. The

price of some 3G tools also may be very expensive for a number of

individuals. You should learn how to compare your options on the internet

and through local dealers.

From GPRS to UMTS

Several network elements can be used again, starting from GPRS network. The

included ones are HLR or home location register, VLR or visitor location

register, EIR or equipment identity register, MSC or mobile switching

center which is vendor dependent, AUC or authentication center, GGSN or

gateway GPRS support node and SGSN which is vendor dependent or serving

GPRS support node.

If you are starting from GSM or global service for mobile communication

radio network, you cannot use some elements again, such as BSC or base

station controller and BTS or base transceiver station. These can stay

inside the network and be used in two network operations wherein 2G and 3G

networks exist together. At this occasion the network migration and recent

3G terminals are also present for use within the network.

Some Functionalities

The UMTS network shows and introduces some recent network elements that

work as specified by 3GPP, namely MGW or media gateway, base station or

node B or RNC or radio network controller. The functions of SGSN and MSC

will vary when going toward UMTS. In a GSM system, the MSG controls all the

circuit switched operations such as linking A and B subscriber through the

network. In UMTS, the MGW or media gateway is responsible for all types of

data transferred in both the pack switched networks and the circuits. MSC

and SGSN manage operations of MGW. The nodes will be named again to GSN and

MSC servers.

Discussing Security

Compared to its 2G predecessors, 3G networks are a lot more secure. It

allows the UE to authenticate the network it is attaching to, allowing the

user to be certain that the network is the right one and not just a mere

impersonator. 3G networks usually make use of the KASUMI block crypto,

compared to the old A5/1 stream cipher. Several major weaknesses in the

cipher have been discovered, however.

There is also end to end security provided when application frameworks like

IMS are accessed.

Apple has released various popular tools and devices, particular the iPod

and the Mac PC. However, the release of the iPhone has created waves of

followers, hoping to get a glimpse and experience with 3G technology.

iPhone is among the first of its kind, and is also considered as one of the

best gadgets ever created to meet the demands and needs of individuals from

all over the globe. Here are some more details about the iPhone.

Power-Packed Features

The iPhone is an internet-capable quad band and multimedia GSM

EDGE-supported mobile phone unit created and developed by Apple Inc. The

functions of the iPhone include several of the basic camera phone and

multimedia player. The device also provides internet services, which

includes email, web browsing, text messaging, Visual Voicemail and local

Wi-Fi connectivity. User input can be done through the multi-touch screen,

complete with buttons and a virtual keyboard. Apple has filed over 200

patents associated with the technology backing the iPhone.

More Features

The iPhone boasts of having very fast 3G wireless technology, so you can

enjoy talking to individuals from all over the world with crisp clear

resolution on your screen. You can also download pictures, videos and other

data straight from the internet and store these in the gadget. There is GPS

mapping, support for enterprise features such as the new App Store and

Microsoft Exchange. Similar to the original iPhone model, the new one mixes

three products in one tool. There is a widescreen iPod, a state-of-the-art

phone, plus a breakthrough internet unit with high capacity HTML email and

a desktop-category web browser.

iPhone Photos

You can easily take photos and send these to other people, regardless of

the time and date, via the 3G technology. When taking photos, it is

important that you use and apply the proper methods to get the best

results. First of all, hold the camera very still with both hands, avoid

wiggling or shaking until the shutter has fully closed in the viewer.

You can then compose the shot using your finger on the camera button. The

shutter will let go and click one you take your finger off. Do all

composing with the finger on the trigger, then lift the finger when you

find the right shot in the viewer. Try not to shoot on fast-moving objects

and other items in low light. The iPhone takes good clear images, but you

cannot expect its photo capabilities to be exactly the same as a DSLR.

On the Battery

The iPhone 3G uses an internal battery. Some individuals try to create a

case and battery combination, but they will also require syncing of the

unit with a PC. The iPhone still needs to be synced out because it cannot

do with an external battery. The 3-in-1 external rechargeable battery is

the right solution, complete with protective case. Using the item, you can

take the battery and use the iPhone 3G conveniently.

Some of the included advantages are longer battery life for the iPhone 3G,

access to every port on the device, the protective case function to the

tool, excellent integration and control whenever syncing is done. There is

also an LED power indicator. The price of an iPhone 3G will differ,

depending on the source and added features.

You can get more info by visiting an authorized dealer or settling for

other products over the internet.

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.

Before you decide to upgrade your current gadget and start investing on 3G

technology, 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 a 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.
