Verizon Bridging CDMA and GSM | Gadget Lab from Wired.com

what does this mean?! Posted by: mose. | Dec 3, 2007 6:30:58 AM horrible article. Posted by: leet0 | Dec 3, 2007 7:40:03 AM i understood the article perfectly. is it that hard to understand gsm and cdma? Posted by: Cally | Dec 3, 2007 8:38:41 AM It's about time. CDMA is horrible. Now if Sprint would shift to GSM, then CDMA can die forever! Posted by: James | Dec 3, 2007 9:04:30 AM Your analysis is a bit confusing. You write, "Though the new handsets will still ride Verizon's own CDMA network for voice communications, they'll be able to connect to GSM networks for data transfer." That's rather confusing. Sure, LTE is an evolution of the GSM standard, but that's different than using GSM generically here.

CDMA Development Group Shows Roadmap for CDMA2000 Evolution

CDMA2000 1xEV-DO Revision C: This advanced interface will deliver higher data rates and spectral efficiency along with low latency, making it ideal for enriched multimedia services. Revision C will support flexible and dynamic channel bandwidth scalability from 1.25 MHz up to 20 MHz and will be backward-compatible with Revisions A and B. Currently, 3GPP2 is evaluating various proposals, which include OFDM, MIMO, SDMA and Interference Cancellation techniques, with the harmonization of the proposals to be completed by June of this year. It expected that Revision C will increase the peak rates up to 200 Mbps in the downlink, also providing gain in sector throughput, which is essential for cost-effectively supporting several broadband users simultaneously. The standard is expected to be published by Q2 2007 with commercial products in the second half of 2008.

GSM vs CDMA GSM and CDMA are the two main competing network technologies deployed by cellular service providers world over. Understanding the pros and cons of both the technologies will help you make right decision according to your requirement. GSM ( Global System for Mobile Communications) originated in Europe in 1990. The GSM Association is an international organization founded in 1987, dedicated to developing, providing and overseeing the worldwide wireless standard of GSM. While CDMA (Code Division Multiple Access ) is a proprietary standard designed by Qualcomm Inc in United States and has been the dominant network standard for North America and parts of Asia. It became an international standard in 1995. However now, GSM networks have penetrated the United States and the CDMA networks have spread in other parts of the world. People of both the camps claim that their architecture is superior to the other. The Technology: Mobile personal communication systems use microwave frequencies above 800 MHz for transmission and reception. All service providers operate in some pre allocated frequency bands according to international standards.
