There is an announcement from CDMA on their recent technology enhancements. Users can now enjoy uninterrupted data while talking or texting, and continue to stream while picking up a call. Read on for more info.

CDMA2000 is a 3G technology which has been widely deployed across 103 countries and territories with 288 operators serving more than 450 million subscribers. This technology is deployable in the 450, 700, 800, 1700, 1900, AWS and 2100 MHz bands.

CDMA Development Group (CDG) has now emerged with an evolution of 3G CDMA wireless systems globally. They announced that the specifications for CDMA2000 1X Advanced have been completed and published by the 3rd Generation Partnership Project 2. This technology which would be available from 2010 allows 3G CDMA operators to significantly increase the voice capacity of their CDMA2000 1X network by taking advantage of several interference cancellation and radio link enhancements. Below are the enhancements in technology said to be available in 1X Advanced.

• Base transceiver station (BTS) interference cancellation
• Improved power control
• Early frame termination
• Smart blanking

The complete set of 1X Advanced enhancements can theoretically quadruple the voice capacity of CDMA2000 1X systems in the same 1.25 MHz of spectrum. Apart from this, the group also stated that a complementary device enhancement known as simultaneous 1X Voice and EV-DO Data will also be made available which enables CDMA2000 devices to access EV-DO packet data services while in an active 1X circuit-switch voice call. This device enhancement allows which enables the concurrent voice and data services, is independent of the air link standard and infrastructure, and allows users to send emails or access the Web, and use GPS to update maps or download real-time traffic information while on voice calls.

We’ve mentioned this before and we proclaim it again. HTC takes its customer feedback rather seriously and it comes across as a genuinely caring mobile manufacturer.

HTC Diamond is now coming in CDMA version and is slated to hit North America very soon. And no, it looks different from GSM/HSDPA ones but we get a sneaking feeling that both are the same devices. 

Ever wished for a windows mobile powered phone complete with a slide-out QWERTY keyboard and CDMA EVDO instead of GSM/HSDPA? This one is for you. Read on.
