Telefonica Tests CDMA450 1xEV-DO

Nortel and Telefonica O2 Czech Republic say that they have successfully demonstrated Europe's first CDMA2000 1xEV-DO Rev A call in the Telefonica O2 Czech Republic network at 450 MHz radio spectrum.

"We are glad that the 1xEV-DO Rev A deployment pilot has been successfully accomplished," said Pavel Kolar, Chief Network Infrastructure Officer, Telefonica O2 Czech Republic. "We have experienced significant improvement on the throughput and latency of Rev A data transfer. It clearly demonstrates that the latest CDMA2000 technology evolution, in combination with excellent radio propagation in the 450 MHz band, delivers improved customer benefits."

"Nortel's eleven-year experience with CDMA is helping us develop leading-edge solutions which benefit wireless operators by increasing revenue potential and enhancing the subscriber experience," said Wim Te Niet, president Central Region EMEA, Nortel. "With Telefonica O2 Czech Republic we're showing how Nortel's unique blend of broadband access products, IP core experience, network services and ability to deliver simple network upgrades helps to get the best from the wireless spectrum."

The call was enabled by a simple upgrade from 1xEV-DO Rev 0 to Rev A technology. Using the same 1.25 MHz channel, CDMA2000 1xEV-DO Rev A provides both forward and reverse links with more capacity and higher data rates, with up to 3.1 Mbps in the forward link and 1.8 Mbps in the reverse link. These faster data rates combined with Quality of Service (QoS) and low latency, enables the provision of 3.5G services such as wireless gaming, streaming audio and video, and high performance push-to-talk capabilities. In addition to the Nortel upgrade, the demonstration was achieved using an ADU-500A CDMA EV-DO Rev A wireless modem from AnyDATA.

The 1xEV-DO Rev A implementation only required one hardware addition - the Rev A channel card - on the Telefonica O2 Czech Republic network to enable the new service and maximize the operator's existing investment in 450 MHz spectrum and core network equipment."
