Course 332 - CDMA2000 1xRTT: 2.5G
Spreading Rate 1 Codes, Channels, Call Processing, and Networks
Scope
This
one-day seminar takes a deeper look at the interim stages in migration from IS-95
CDMA systems to 3G. It explores the enhancements provided by IS-95B and gives a
detailed view of the codes, channels, call processing protocols, data
capabilities, and network architecture of Spreading Rate 1 (1xRTT) systems,
often called “2.5G” technology. At conclusion, participants should be able to
describe basic channel functions and configuration, data capabilities, basic
network architecture and steps involved in call processing examples.
Applicability
CDMAone
and CDMA2000 systems of all manufacturers.
