Types of 3G Phones

Hi Friends,

3G fever is taking over India in a few months from now as private telecom companies are going to start 3G services all over India.

Having a 3G network is ONLY good if we have a 3G phone with a 3G SIM card in it 🙂

I did some research on 3G phones and found some useful information which i wanted to share for the benefit of all.

There are 2 types of 3G phones available today, some give true 3G experience while others can support only low speed 3G access.

What is WCDMA and HSPA?
HSPA (High Speed Packet Access) is a new generation communication protocol that allows data connections up to 21 Mbps per user in good coverage and quality conditions. Today mobile phones, datacards & USB dongles are available with HSPA.

WCDMA (Wideband Code Division Multiple Access) is a 3G technology version that allows data connections up to 384 kbps per user (64kbps, 128kbps, 384 kbps) in good coverage and quality conditions.

What are the benefits of HSPA over WCDMA?
HSPA allows you to get the best experience of 3G. Given the same bandwidth for WCDMA and HSPA, HSPA allows higher bit rates compared to WCDMA to be delivered to the end users.
Major advantages include:
Faster downloads and sophisticated applications support
Faster response time between network and device, improving the download times and network performance
Improved network performance also leads to significant savings in the battery life of the device
Far better experience due to quality reception resulting from the higher bit rates
