ELP 4008  ★★   

The GPRS/UMTS/LTE Workshop course presents architecture and details of the air interface of the 2G, 3G and 4G packet switch systems. Participants are first introduced with the GPRS/EGPRS system and discover the needs for 3G system. Next details of the 3G system are presented including the air interface, packet switched core network, Quality of Service (QoS) handling, security aspects and service provisioning. Finally participants become familiar with the advantages of the LTE and details of LTE architecture, air interface and service provisioning in LTE by IMS. The training provides brief and excellent overview and comparison of the GPRS, UMTS and LTE systems.

Target audience – Who should attend and benefit

The training is addressed to both managerial and technical staff who require an overview and comparison of the 2G, 3G and 4G systems.

Prerequisites – What you are supposed to know prior to the course

No specific requirements, however general knowledge in GSM, UMTS and LTE is beneficial.
