Special Networks Communications with LTEUnified communication networks

Special Networks - specific different / additional requirements with respect to

commercial networks

Examples - Public safety, defense, intelligence/security, IoT, railways, smart grids

Today special networks use dedicated technologies, like TETRA and DMR, for

mission critical voice and data communications

LTE is strong candidate as unifying, to the extent possible, wireless technologies

Current Release 8, 9 and 10 mostly cater to commercial systems

Future networks definition (release 12 and beyond) should fully meet the special

networks requirements

3GPP is working in collaboration with TCCA, ETSI, NPSTC and critical

communication industries to build a robust LTE migration roadmap for public safety

and critical communication.

Preserve strengths of LTE while adding features needed for special networks

Maximize the technical commonality between commercial and special network

aspects

India 5G standardization exercise may evolve with similar collaborationRequirements and technical

inputs

Future wireless communication networks challenges From LTE to LTE-Advanced and Beyond

Growth in data rate and traffic volume expected in the range of 1000x (*) in ten years

Growth in the number of connected devices up to 50 billion by 2020 (**)

Growth in the type of devices: Human centric devices tenfold surpassed by extremely low

cost, energy efficient Machine Type Communication devices (connected home, cars,

sensors, grids, wearables) to create the connected society

Wider range of applications, including strategic communication and smart battlefield

management, for Defense, National Security, Emergency Response, Public Safety,

Railways, Smart Grids and IoT networks.

Special Networks support Path to unified networks

Use cases for special networks must be included as part of 3GPP

standardization in order to get special networks requirements fully met by

the commercial networks technology

Maximize technical commonality between commercial and special networks

features providing the best and most cost effective solution for both

application

Supports innovative application of advanced commercial network radio

feature/technology (eg, Power efficiency, Low latency, AAS, Beamforming)
