PRAGUE -- Nortel and Telefónica O2 Czech Republic, the largest provider of wireless voice and data services in the Czech Republic, have teamed to show how operators can use broadband wireless spectrum more efficiently.

Today, the two companies successfully demonstrated Europe's first CDMA2000 1xEV-DO Rev A call in the Telefónica O2 Czech Republic network at 450 MHz radio spectrum. This broadband capability is expected to enable Telefónica O2 Czech Republic to deliver more IP wireless services such as mobile music and interactive 3D gaming, VoIP, and high-speed file transfers; and support real-time interactive access to services such as push-to-talk, mobile television and video telephony.

"We are glad that the 1xEV-DO Rev A deployment pilot has been successfully accomplished," said Pavel Kolár, Chief Network Infrastructure Officer, Telefónica 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."
