LTE Essentials

1 day

Download brochureThe course provides all the key information about LTE system in a nutshell without going into the technical details. It starts with explanation of the background behind LTE and presentation of the LTE system overview inducing architecture, IP connectivity, QoS, and new radio access. Then, practicalities are addressed such as: achievable performance, current status of spectrum auctioning and equipment availability. The course is concluded by discussing possible LTE services and comparing LTE to other broadband systems.

Introduction to LTE

• 2G to 4G radio and core network evolutions (GSM, UMTS, HSPA, LTE and LTE Advanced)
• 3GPP requirements imposed on LTE (throughputs, network capacity, delays)
• Spectrum bands, bandwidths, system parameters and mobile terminal capabilities
• IMT-Advanced requirements for 4G system

LTE System Overview

• LTE network elements: terminals (mobile phone, laptop, PC), access network, core network and IMS
• IP in the network: All IP and always-on concepts
• QoS concept and parameters
• Security in the LTE network (IPsec and LTE security)
• Common IP intersystem part: IMS and its relation to IP-CANs
• Radio access network technologies (OFDMA, MIMO, spectrum flexibility)

LTE Practical Aspects

• LTE performance requirements
• Practically achievable LTE performance (range, coverage, throughputs, number of users)
• Current status of LTE trials and commercial deployments
• Current status of spectrum auctions
• Possible LTE deployment scenarios
• Available handsets and possible evolution

LTE Services

• Potential 4G services
• Flexibly policy and charging options for operators
• SMS and 2G/3G voice in LTE (problems and solutions)
• Packet services: MBMS (mobile TV), internet access, VoD, online gaming, location services
• LTE as competition for fixed networks

LTE Network versus Other Networks

• Network migration possibilities from 2G/3G to LTE
• LTE interworking with UMTS/GSM and WiMAX/WiFi
• LTE international roaming
• LTE compared to WiMAX
• Evolution of LTE towards 4G system (LTE advanced – features, differences, possibilities)
