The call, achieving a peak data rate of 3.09 Mbps, was made between a test set based on a commercially available Nokia 2285 handset upgraded with a Nokia 1xEV-DV chipset and a Racal Instruments, Wireless Solutions Group, 1xEV-DV basestation emulator. This chipset is the world’s first to support complete 1xEV-DV Release C functionality.
Approved in mid-2002 by the Telecommunications Industry Association (TIA) and the International Telecommunications Union (ITU) as an official 3G standard, cdma2000 1xEV-DV, also known as IS-2000 Release C, delivers a maximum forward link (base station to handset) data rate that is 20 times greater than the peak rate deployed in today’s IS-2000 Release 0 CDMA networks. Furthermore, IS-2000 Release C provides typical user throughput of 1 Mbps in a 1.25 MHz frequency channel and system-wide throughput that ranges from 420 Kbps to 1.7 Mbps depending upon traffic and channel conditions.
“In less than one year, Nokia has led the development of the 1xEV-DV specification from an approved standard to a functional handset that can be used for infrastructure lab interoperability testing and subsequently, operator field testing,” said Adam Gould, vice president of technology management and strategy, CDMA for Nokia Mobile Phones. “Our experience in CDMA technology uniquely positions Nokia to support incumbent cdma2000 operators transitioning to the 1xEV-DV standard.”
Nokia continues to contribute to the continuing evolution of 1xEV-DV technology as 3GPP2 finalizes specification of IS-2000 Release D later this year. Release D adds a higher data rate capability on the reverse link (handset to base station) than what is available with today’s CDMA networks and includes all of the features and functionality of previous IS-2000 releases including the high-speed forward link capabilities of Release C, enabling quality of service dependent applications such as mobile online gaming.
“The success of Sprint PCS Vision services is continuing to create new demand for increasingly data intensive applications,” said Oliver Valente, Vice President of Technology Development at Sprint. “As one of the original supporters of 1xEV-DV technology, Sprint PCS clearly understands the power and practicality that it can deliver to both operators and end users.”
