3G:
   Simoco rocked the world this morning by introducing its spin on the laptop, called the sSimbook 3G. If you're the rude sort you could call it a fancy netbook, what with its Atom processor and 10.1-inch display, but that screen is higher res than your average Eee, and it also sports integrated 3G wireless and a hot-swappable SIM card, so it's definitely trying to define its own niche. It looks to be running Windows 7, which isn't particularly netbooky, and also has integrated A-GPS with a copy of Ovi Maps, HDMI output, a rated 12 hour battery life, and the usual Bluetooth and WiFi connectivity, all in a 2cm (.78 inch), 2.7lb aluminum body that's understated, sophisticated, and should make most Simoco fans very happy -- Simoco fans who are looking for a tiny laptop, anyway. There's a fancy promotional video after the break, and while we don't have any anticipated release date or price just yet, we'll be learning more at Simoco. We promise not to make too many references.

   3G refers to the third generation of mobile telephony (that is, cellular) technology. The third generation, as the name suggests, follows two earlier generations.

   The first generation (1G) began in the early 80's with commercial deployment of Advanced Mobile Phone Service (AMPS) cellular networks. Early AMPS networks used Frequency Division Multiplexing Access (FDMA) to carry analog voice over channels in the 800 MHz frequency band.

   The second generation (2G) emerged in the 90's when mobile operators deployed two competing digital voice standards. In North America, some operators adopted IS-95, which used Code Division Multiple Access (CDMA) to multiplex up to 64 calls per channel in the 800 MHz band. Across the world, many operators adopted the Global System for Mobile communication (GSM) standard, which used Time Division Multiple Access (TDMA) to multiplex up to 8 calls per channel in the 900 and 1800 MHz bands.
The International Telecommunications Union (ITU) defined the third generation (3G) of mobile telephony standards - IMT-2000 - to facilitate growth, increase bandwidth, and support more diverse applications. For example, GSM could deliver not only voice, but also circuit-switched data at speeds up to 14.4 Kbps. But to support mobile multimedia applications, 3G had to deliver packet-switched data with better spectral efficiency, at far greater speeds.

   However, to get from 2G to 3G, mobile operators had make "evolutionary" upgrades to existing networks while simultaneously planning their "revolutionary" new mobile broadband networks. This lead to the establishment of two distinct 3G families: 3GPP and 3GPP2.

   The 3rd Generation Partnership Project (3GPP) was formed in 1998 to foster deployment of 3G networks that descended from GSM. 3GPP technologies evolved as follows.

. General Packet Radio Service (GPRS) offered speeds up to 114 Kbps.

. Enhanced Data Rates for Global Evolution (EDGE) reached up to 384 Kbps.

. UMTS Wideband CDMA (WCDMA) offered downlink speeds up to 1.92 Mbps.

. High Speed Downlink Packet Access (HSDPA) boosted the downlink to 14Mbps.

. LTE Evolved UMTS Terrestrial Radio Access (E-UTRA) is aiming for 100 Mbps.


   GPRS deployments began in 2000, followed by EDGE in 2003. While these technologies are defined by IMT-2000, they are sometimes called "2.5G" because they did not offer multi-megabit data rates. EDGE has now been superceded by HSDPA (and its uplink partner HSUPA). According to the 3GPP, there were 166 HSDPA networks in 75 countries at the end of 2007. The next step for GSM operators: LTE E-UTRA, based on specifications completed in late 2008.
A second organization - the 3rd Generation Partnership Project 2 (3GPP2) -- was formed to help North American and Asian operators using CDMA2000 transition to 3G. 3GPP2 technologies evolved as follows.

. One Times Radio Transmission Technology (1xRTT) offered speeds up to 144 Kbps.

. Evolution - Data Optimized (EV-DO) increased downlink speeds up to 2.4 Mbps.

. EV-DO Rev. A boosted downlink peak speed to 3.1 Mbps and reduced latency.

. EV-DO Rev. B can use 2 to 15 channels, with each downlink peaking at 4.9 Mbps.

. Ultra Mobile Broadband (UMB) was slated to reach 288 Mbps on the downlink.

   1xRTT became available in 2002, followed by commercial EV-DO Rev. 0 in 2004. Here again, 1xRTT is referred to as "2.5G" because it served as a transitional step to EV-DO. EV-DO standards were extended twice - Revision A services emerged in 2006 and are now being succeeded by products that use Revision B to increase data rates by transmitting over multiple channels. The 3GPP2's next-generation technology, UMB, may not catch on, as many CDMA operators are now planning to evolve to LTE instead.
In fact, LTE and UMB are often called 4G (fourth generation) technologies because they increase downlink speeds an order of magnitude. This label is a bit premature because what constitutes "4G" has not yet been standardized. The ITU is currently considering candidate technologies for inclusion in the 4G IMT-Advanced standard, including LTE, UMB, and WiMAX II. Goals for 4G include data rates of least 100 Mbps, use of OFDMA transmission, and packet-switched delivery of IP-based voice, data, and streaming multimedia.

   From the time of telegraphs Indian telecom sector has witnessed an immense growth and has diversified into various segments like, Fixed Line Telephony, mobile telephony, GSM, CDMA, WLL etc. The telecom industry is growing at a fast pace introducing newer technologies. Even the network operators and handset providers are also coming up with newer value added services and advanced technology cell phones with multimedia applications.

   Now it's time to welcome the much-awaited 3G Technology. Bharat Sanchar Nigam Limited is all set to launch the technology by December 2007. Not only the network providers but also the handset providers in India are waiting eagerly for the launch of 3G to earn very high revenues from the value added services provided by the technology.

   The technology is initially being launched on CDMA platform. The technology is being tested over various platforms and cellular networks.

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. CDMA2000 3G Subscribers Base Worldwide

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.
