3G Technology

If you want augmented bandwidth, multiple mobile applications and clarity of digital signals, then3G (Thrid Generation Technology) is your gateway. GSM technology was able to transfer circuit switched data over the network. The use of 3G technology is also able to transmit packet switch data efficiently at better and increased bandwidth. 3G mobile technologies proffers more advanced services to mobile users. It can help many multimedia services to function. The spectral efficiency of 3G technology is better than 2G technologies. Spectral efficiency is the measurement of rate of information transfer over any communication sytem. 3G is also known as IMT-2000.


3G technologies make use of TDMA and CDMA. 3G (Thrid Generation Technology) technologies make use of value added services like mobile television, GPS (global positioning system) and video conferencing. The basic feature of 3G Technology (Thrid Generation Technology) is fast data transfer rates. However this feature is not currently working properly because, ITU 200 is still making decision to fix the data rates. It is expected that 2mbit/sec for stationary users, while 348kbits when moving or traveling. ITU sell various frequency rates in order to make use of broadband technologies. Network authentication has won the trust of users, because the user can rely on its network as a reliable source of transferring data.3G technology is much flexible, because it is able to support the 5 major radio technologies. These radio technologies operate under CDMA, TDMA and FDMA.CDMA holds for IMT-DS (direct spread), IMT-MC (multi carrier). TDMA accounts for IMT-TC (time code), IMT-SC (single carrier). FDMA has only one radio interface known as IMT-FC or frequency code. Third generation technology is really affordable due to the agreement of industry. This agreement took pace in order to increase its adoption by the users. 3G (Thrid Generation Technology) system is compatible to work with the 2G technologies. 3G (Thrid Generation Technology)technologies holds the vision that they should be expandable on demand. The aim of the 3G (Thrid Generation Technology) is to allow for more coverage and growth with minimum investment.



3G technologies (Third Generation Technologies) 


There are many 3G technologies as W-CDMA, GSM EDGE, UMTS, DECT, WiMax and CDMA 2000.Enhanced data rates for GSM evolution or EDGE is termed to as a backward digital technology, because it can operate with older devices. EDGE allows for faster data transfer than existing GSM.EDGE was introduced by AT& T in 2003.EDGE has increased the GSM coverage up to three times more. EDGE is a 3G Technology (Thrid Generation Technology); therefore it can be used for packet switched systems. Universal mobile telecommunications systems .UMTS conforms to ITU IMT 2000 standard. It is complex network and allows for covering radio access, core network and USIM (subscriber identity module). It is a relatively expensive technology for the network operators because it requires new and separate infrastructure for its coverage. The GSM is the base of this technology. CDMA is also referred to as IMT-MC. this technology is close to 2G technology GSM because it is also backward compatible. Digital enhanced cordless telecommunications (DECT) is another 3G Technology (Thrid Generation Technology). DETC was developed by European telecommunications standards institute; however it is now widely popular in the other countries of the world as well. It runs over a frequency of 1900Mhz. WiMax is a 3G Technology (Thrid Generation Technology) and it is referred to as worldwide interoperability for microwave access. It is a wireless technology. It transmits variety of wireless signals. It can be operated on the multi point and point modes. it is portable technology. This technology is based on the wireless internet access. Name of the WiMax was developed in 2001 by WiMax forum. This technology removes the need for wires and is capable enough to provide 10mbits/sec. it can connect you to hotspot.
3G TECHNOLOGY

3G or Third Generation technology is a convergence of various Second Generation telecommunication systems. The technology is intended for SMARTPHONES - multimedia cell phones. Video broadcasting and other e-commerce services such as, stock transactions and e-learning will now be made possible much faster. It offers 3 Mbps speed for downloading, which is very high as compared to that of the 2G technology. The 3G technology provides for internet surfing, downloading, e-mail attachment downloading, audio-video conferencing, fax services and many other broadband applications. 
EXISTENCE OF 3G TECHNOLOGY

3G Technology was implemented in Japan for the first time in the world. Today the technology is serving 25 countries over more than 60 networks having its existence in Asia, Europe and USA. Video conferencing has been a major factor in the success of the technology.

3G TECHNOLOGY & HUMAN RESOURCES


Not only the media and entertainment but the business sector too has started utilizing the 3G applications worldwide. Video conferencing allows two individuals at a distance to interact in the same way as they could have done in person. The technology is being implemented at various functional level of the business such as, marketing, human resources, etc.
Mobile Interview

In today's global scenario, the 3G technology will enable organizations and qualified candidates to have a telephonic interview in a modern way through video conferencing. Traditional telephonic interview and personal interviews may be replaced by 3G voice and video conferencing. This will reduce the cost and save the time of both the organizations and the candidates. 
Conferences

3G technology provides for video conferencing which can help the Human Resource Department interact with their seniors at the time of urgency without wasting other resources. This can be very much helpful when the concerned person is out of state or country.
File Transfer

With the advent of video and audio multimedia and a faster rate of downloading e-mail attachments, employees in an organization can request any urgent file or report they need to present to the clients. This will again reduce the burden on organization's resources and increase employee effectiveness. 
e-learning & m-learning

3G technology provides for internet browsing that will help the employees to surf and learn using their 3G cell phones while traveling (m-learning) or from home. The organizations can schedule training modules for the employees of other branches through video conferences.

How 2 SpeedUp Ur Symbian Mobile

1. Install firmware update with care:-


Nokia periodically releases phone firmware updates which can be used to patch the device in both software and hardware side. But sometimes these are only minor upgrades with some extra software applications. Updates are usually installed to phone memory, which would eventually affect overall device performance by limiting resources for other applications. So read the change log, update size and compare it with your phone memory size before proceeding with new firmware upgrades.


2. Speed up Nokia phone with software:-


Symbian phones also have disk partitions, system registry etc. But these are not accessible to normal users unless they are using file explorer software. Software installations and file transfers create logs files, thumbnail images, registry errors and other junk files in Symbian phones. Memory up is a software that aids in recovering dispersed RAM in Symbian OS and arranges them to speed up the device. It has both pro and free versions. The free version is also good for minimal recovery from unwanted items.


3. Remove unnecessary applications:-


Usually we install mobile applications for testing, and later leave them on the phone unused. Periodical checking should be done to remove these unnecessary softwares. Antivirus software is not recommended for Symbian S60 V3 and other latest phone models. Also make sure that you are not installing applications to phone memory.


4. Kill background running and autostart apps:-


Few applications automatically start with phone boot and they will work in the background while the phone is multitasking. For instance, in Nokia series and music phones, the default music player is an auto start app. Also when we open messages and other programs, we forget to exit them. So altogether they will reduce the memory available to needed applications and results in “phone out of memory warnings”. It’s very simple to kill these unwanted applications. Press firmly on standby button. Open each of them and exit.


5 . Use default themes:-



There are lots of custom Nokia Symbian themes available for download. Though they look better than your default themes, they would affect the total network and application speed of the device.  There is also a chance for malware infections.
peed of any mobile phone depends on the processor and the installed phone memory. So it’s the discretion of the user to select a suitable phone matching his requirements. These tips would additionally help them to maintain or manage existing memory performance and speed.
