3G (Third Generation Technology)

Coming with the history of 3G Technology it was implemented in Japan for the first time in the world. But today with growing time 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.

While 2G stands for second-generation wireless telephone technology, 1G networks used are analog, 2G networks are digital and 3G (third-generation) technology is used to enhance mobile phone standards. The main reason for the evolution of 3G was due to the limited capacity of the 2G networks. All the function performed in a 2G network can be performed in a higher speed in a 3G network.

With 3G technology it has been possible to transmit packet switch data efficiently at better and increased bandwidth. The amount of bandwidth needed for 3G services could be as much as 15-20 Mhz, whereas for 2G services a bandwidth of 30-200 KHz was used. Hence, for 3G huge bandwidth is required. The aim of the 3G (Thrid Generation Technology) is to allow for more coverage and growth with minimum investment.

Though there are many advantages of 3G network,there are few draw backs like upgrading the base station and cellular infrastructure to 3G incurs very high cost and it also has a very high power consumption. But the drawbacks will be minimized when this technology will be used extensively.

The highlight of 3G is video telephony. But now much awaited 4G technology stands to be the future standard of wireless devices.

Motorola XOOM-Android Tablet

The Motorola Xoom is a 10.1-inch tablet which is slightly larger than the iPad. This is the first tablet running Android 3.0 "Honeycomb," the tablet-optimized version of Google's popular Android operating system. The Xoom's hardware is solid. This is truly the first real competitor to the Apple iPad. The Xoom has better specs all-around than the current iPad. The design is sober and discrete.
The hardware is sturdy and impressive. The Xoom weighs in at 730 grams and is 12.9 millimeters thick –almost identical to the iPad, the screen is wider, with 1280 x 800 pixel resolution. That gives the Xoom an edge when watching movies and browsing larger websites. The top quarter of the Xoom's rear is encased in a soft-touch plastic. There is no issue on touch screen responsiveness but it is somewhat a heavy device.
There is 32GB storage for apps, movies, music and photos. There’s a 2.0 megapixel front-facing camera for video chat and a five-megapixel shooter on the back. The 5.0 mega pixel shooter on the back actually produces decent well-balanced pictures.
The Xoom speakers are worth further mention. They are loud and to the point that sound is distorted coming out them. But when things are at a more manageable level, the sound is great. Listening to podcasts and talk radio is without effort. You have the power button on the back and volume buttons on the left-hand bezel, and that is it.
The XOOM is vast on connectivity, with EVDO Rev.A, WiFi a/b/g/n, Bluetooth 2.1+EDR and USB 2.0, along with a 4G LTE update in the pipeline, but it’s worth noting that it won’t make voice calls. If you want to actually talk with someone using the XOOM you’ll have to pick a VoIP client. With Skype, Fring, Qik and others in the Android Market, and Google Talk preinstalled in Honeycomb, most users should find something to fit that gap.
Much of the XOOM’s strength comes from Android 3.0 Honeycomb. It’s a convincing and polished platform, which brings a highly usable multitasking environment to the tablet marketplace, neatly distinct from the “oversized smartphone” accusations levied at previous Android slates. The XOOM may only be the first Honeycomb slate, but it’s a strong start to what’s going to be a fiercely competitive race.
