Recently, CDG announced that the number of EV-DO users worldwide has exceeded 100 million. A report recently released by ABI, a well-known market research company, shows that the number of global EV-DO version A users has surged more than eightfold from the second quarter of 2007 to the second quarter of 2008. ABI also predicts that by 2013, the number of EV-DO version A users will exceed 54 million, and version B will also exceed 25 million. All these illustrate the strong global growth of CDMA's future evolution technology.
In addition, Qualcomm will also demonstrate the significant capacity enhancement that 3G interference cancellation technology brings to the network. This technology demonstration is based on CSM6850 and implements reverse link interference cancellation for EV-DO version A / B technology.
Currently, there are more than 750 million 3G users worldwide. Whether it is HSPA + or CDMA future evolution, it reflects the continuous efforts of leading companies such as Qualcomm to continuously improve network capacity and data rate through technological evolution, thus bringing users an increasingly perfect mobile broadband experience .
The second highlight: IT communication convergence brings mobile Internet close at hand
With the advent of the mobile broadband era, how users can easily access the mobile Internet through rich terminals has become the focus of the industry. Qualcomm is committed to promoting the popularization of mobile Internet access through the integration and innovation of communications and IT.
Qualcomm's Gobi technology is one of them. By integrating HSPA and EVDO modules into notebook computers and other devices, Gobi can enable users to achieve high-speed Internet access anytime, anywhere in the world. Recently, American operators AT & T and Qualcomm announced that Gobi ’s global mobile Internet technology has been certified for use on AT & T ’s mobile broadband network. The two companies also announced certification for laptops from Panasonic and HP. Panasonic's two rugged laptops with built-in Gobi—the rotatable tablet laptop Toughbook 19 and the flagship laptop Toughbook30—are now approved to run on AT & T-based HSPA networks.
In addition, notebook manufacturers such as Hewlett-Packard, Lenovo, Dell and others have also announced that they will have built-in Gobi modules in their newly launched notebooks, and several operators including T-Mobile, Telefónica, Verizon Wireless and Vodafone have also completed Gobi's certification reflects the industry's extensive support for Gobi.
Snapdragon is another technology that Qualcomm is positioning for IT communication convergence. Due to its extremely high processing speed and extremely low power consumption, Snapdragon makes it possible for pocket terminals between laptops and mobile phones. Terminals using the Snapdragon platform will have exciting performance such as gigahertz processing speed, GPS navigation, global Internet access, multimedia processing, and high-definition video decoding. Currently, more than 15 Snapdragon-based devices are under development. The first terminal It is expected to be listed at the end of this year.
Of course, another highlight of the exhibition is that HTC uses the Google Android platform G1 mobile phone.
