Introduction to EvDO
Introduction to EvDO

(8 hours)

Over the past few years the wireless technology industry has seen massive growth with ever increasing mobile subscriber rates. Simple analog radio tools have evolved into sophisticated adaptive technologies. Using advanced hardware, modulation and coding techniques EvDO (evolution of existing systems for data only) can now accomplish wireless solutions, unimaginable a decade ago. Introduction to EvDO is a very informative course that presents a simple and clear explanation of EvDO; its technical capabilities; and its operational benefits when coupled with the baseline wireless networks.
