Skype launches Free Video Chat App for iPhone to greet New Year celebrations

Skype launches free video chat app on your iPhone, iPod and iPad to catch on the 2011 new year celebration. You can talk face to face using your iPhone. There’s no other time than smartphone timely smartphone to come through where Apple doesn't provide: While the iPhone's own FaceTime only works on WiFi, Skype today releases an updated app that will let iPhone users video chat on both WiFi and AT&T's 3G network.
The app will also allow iPad and iPod Touch users to receive video calls, with those using the latest iPod Touch being able to make video calls as well (Skype says that video calls can be made with the iPhone 4, iPhone 3GS, and iPod touch 4th generation with i0S 4.0 or above, and received on the iPod touch 3rd generation and iPad). The only catch is that video calls will have to be with other Skype users, whether on their Apple devices and using the new app, or those using Skype on their computers. It's probably a best thing happened when Skype was down last week and came out strong and makes their users happy this New Year. The free app is available for download now.

4G Technology

Fourth Generation (4G) mobiles

4G also called as Fourth-Generation Communications System, is a term used to describe the next step in wireless communications. A 4G system can provide a comprehensive IP solution where voice, data and streamed multimedia can be provided to users on an "Anytime, Anywhere" basis. The data transfer rates are also much higher than previous generations.
The main objectives of 4G are:
1)4G will be a fully IP-based integrated system.
2)This will be capable of providing 100 Mbit/s and 1 Gbit/s speeds both indoors and outdoors.
3)It can provide premium quality and high security.
4)4G offer all types of services at an affordable cost.

4G is developed to provide high quality of service (QoS) and rate requirements set by forthcoming applications such as wireless broadband access, Multimedia Messaging, Video Chat, Mobile TV, High definition TV content, DVB, minimal service like voice and data, and other streaming services.

4G technology allow high-quality smooth video transmission. It will enable fast downloading of full-length songs or music pieces in real time.
The business and popularity of 4Gmobiles is predicted to be very vast. On an average, by 2009, this 4Gmobile market will be over $400B and it will dominate the wireless communications, and its converged system will replace most conventional wireless infrastructure.

Data Rates For 4G:
The downloading speed for mobile Internet connections is from 9.6 kbit/s for 2G cellular at present. However, in actual use the data rates are usually slower, especially in crowded areas, or when there is congestion in network.
4G mobile data transmission rates are planned to be up to 20 megabits per second which means that it will be about 10-20 times faster than standard ASDL services.
In terms of connection seeds, 4G will be about 200 times faster than present 2G mobile data rates, and about 10 times faster than 3G broadband mobile. 3G data rates are currently 2Mbit/sec, which is very fast compared to 2G's 9.6Kbit/sec.
