This technical brief will introduce the reader to cdma2000 1xEV-DO wireless network concepts and will provide understanding and insight into the air interface. In order to assist maintenance personnel in achieving the high data rates promised by EVDO technology, a particular focus will be given to base station forward-link transmissions. We begin with a review of the evolution of cdma2000 1xEV-DO, followed by a description of the forward-link air interface and key RF parameters. We will then discuss some of the testing challenges in cdma2000 1xEV-DO and describe state-of-the-art test tools that can help wireless networks meet quality of service (QoS) goals.
