With the advancement of technology mobile phones have become more sophisticated than ever. Do you still remember those mobile phones with a limited set of features? If not, it's a quick reminder-the earlier mobile phones were used only for talking-there was no camera feature, no music feature. It's just a matter of few years back, mobile phones had witnessed the tremendous growth in technology. Built-in VGA camera is passé. Mobile users are now using high resolution cameras to store their memorable moments forever. Technology is vrooming ahead at a lighting speed. Isn't that?
Most of the latest mobile phones are 3G enabled. Now, what is 3G? 3G (third-generation) is a wireless communication technology that has emerged from the first generation analog and second generation digital communication systems. 3G is capable of offering increased voice capacity and higher-speed data rates. It allows users to receive TV signal, stream video and send large files. What's more, with the help of 3G technology you can make face-to-face video calls. The entire Nokia N-Series range including Nokia N76, Nokia N80 is 3G enabled smartphones. Other manufacturers like Sony Ericsson, Samsung, Motorola have also brought some high end 3G phones like Sony Ericsson W880i, W850i, W950i, Samsung F500, F510, F520, Motorola KRZR K3, RAZR Maxx, RAZR V3x, RAZR V3xx and so on. But the most sought-after 3G phone available in the market at the present time is the Nokia N93i.
Another technological wonder that is creating great stir in the ‘mobile fraternity’ is 3.5G. 3.5G is nothing but a technology standard used in HSDPA. Now, what does HSDPA mean? HSDPA is an acronym for High Speed Downlink Packet Access. It's an improvement upon the 3G protocol for mobile telephone data transmission.
HSDPA provides download speeds equivalent to an ADSL (Asymmetric Digital Subscriber Line) line on your mobile phone. Theoretically speaking, with HSDPA it is possible to reach data transmission speeds of 8-10 Mbps. That is the reason, HSDPA enabled mobile phones are more faster than the WCDMA 3G phones.
