In August 2005, Nortel and Airvana completed live 1xEV-DO Rev. A calls at Airvana's lab in Chelmsford, Mass. using test handsets provided by QUALCOMM. The calls reached peak download rates of 3.1 Mbps and peak upload rates of 1.8 Mbps -- approximately 12 times faster than available on today's commercial DO Rev. 0 networks. The test calls demonstrated average round-trip delays below 40 milliseconds, which is approximately two times faster than DO Rev. 0.
