Nano-SIM Coming Soon

After Apple’s iPhone, iPad and some recently launched Nokia’s phones like Lumia 800 and 710, the micro-SIMs were just getting into the groove to be adopted by other manufacturers. The adoption of micro-SIM has paved the way for making our portable devices more compact and efficient. But it’s now time to change that and get our devices much more compact and more efficient than it is now.

A Mini-SIM and a Micro-SIM comparision

It’s now time to reduce the size of the SIM (Subscriber Identity Module) once again. After nearly 20 years of producing the first ever SIM card, German manufacturer Giesecke & Devrient (G&D) is now presenting the world’s first Nano-SIM card. This new form of SIM is about 60 percent smaller than the current generation Mini-SIMs which indicates cell phone manufacturers having an advantage of additional free space to include, maybe, larger batteries or more memory or even making the device thinner.
The Nano-SIM will be 15 percent thinner and 30 percent smaller than the micro-SIMs. The SIM will be 12mm x 9mm in dimension. Various network operators worldwide have been given initial samples for the testing process and the Nano-SIM is expected to be standardised by the end of this year through ETSI. Which could mean Apple getting their fair share of the SIM for their next i-device which would be launched next year. There is nothing more to worry for older cell phone users as the Nano-SIM would be backward compatible by the use of an adapter solution for universal use.

2018 Commonwealth Games go for gold

The Gold Coast has clinched the 2018 Commonwealth Games.

    The Gold Coast has beaten the Sri Lankan city of Hambantota in the competition to host the 2018 Commonwealth Games.

Despite several other cities - Perth and Adelaide (Australia), Abuja (Nigeria), Auckland and Christchurch (New Zealand) and the Port of Spain (Trinidad and Tobago) - indicating their interest in hosting the games, it ultimately became a two horse race in 2010 when they failed to enter a bid.

Gold Coast Bid:

   The Gold Coast bid was officially launched on 22 August 2008 by Queensland Premier Anna Bligh.
    Ms Bligh and Gold Coast Mayor Ron Clarke, a former Olympian and Commonwealth Games athlete, both played major parts in the campaign.
  The bid was built around the tagline 'It's our time to shine' and the hope of being 'the greenest games ever held'.
    The Gold Coast leveraged their argument for hosting the games on its extensive experience in hosting large scale sporting events and its existing high quality and well located facilities.

Hambantota Bid:

  Hambantota entered the race as the underdog with a surprise, last-minute bid on 31 March 2010.
The underdeveloped coastal city is the capital of Sri Lanka's southern Hambantota District.
 It was hit by the Indian Ocean Tsunami in 2004 and its games bid was linked to long term development plans for the area including remaking Hambantota as a 'sports city'.
  The tagline for its bid was 'Together: From the heart'.
  The bid was overseen by the Sri Lankan minister for sports, Mahindananda Aluthgamage and the governor of the Central Bank of Sri Lanka, Ajith Nivard Cabraat.

What is 3G Technology

3G Technology

If you want augmented bandwidth, multiple mobile applications and clarity of digital signals, then 3G (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 technology and 3g Technologies characteristics

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.
