4G & 3G Cellular Series

Series Highlights

Cellular transmission speeds have a lot of variables like the underlying technology, the carrier, the location of the cell tower, and the amount of congestion on the network. Third Generation cellular networks were first digital broadband service that allowed, for example, email on a cell phone. Forth Generation (4G) or Long Term Evolution (LTE) services provides faster uplink and downlink transmission speeds facilitating more entertainment and media services together with the potential for higher Quality of Service voice services. The Ossidian 4G and 3G Cellular Series comprises ten fundamentals and advanced level eLearning modules addressing the core technologies and radio frequency standards leading up to and underpinning LTE.
