meeting the expectations of the Networked Society

2020

Dr Magnus Frodigh Director Wireless Access Networks

3G 4G New technologies Wi-Fi 5G GSM

Ericsson Research

› Technology leadership

– the main driver of GSM, HSPA, LTE, LTE-A and 5G

› Innovation

– 50 % of Ericsson patent filings – a major creator of conference papers, journal articles and books

› Cooperation

– leading universities, research organizations and operators

› Strength

– a global organization spanning 3 continents – 40 % holding a Ph.D. degree

In the networked society people, knowledge, devices, and information are networked for the growth of society, life and business.

Mobile Data TRAFFIC

2013 the monthly mobile data traffic volume was

exabytes

≈2

By 2019 the monthly mobile data traffic volume will increase to

exabytes

≈20

1 exabyte = 1018 bytes

Smartphones

2013 the number of smartphones was

billion

1.9

By 2019 the number of smartphones will increase to

billion

5.6

Key Challenges

Diversified wireless accesses

300 MHz 3 GHz 30 GHz 300 GHz

Licensed Controlled sharing Unlicensed Spectrum toolbox

› Provide extreme capacity and multi-Gbps

– bandwidths >500 MHz, frequency >20 GHz – ~1 AP per room indoor, ~10-50 m ISD outdoor

› Higher frequencies enable/require beamforming

– increase link budget, constrain interference

› Low-cost, self-configuring access nodes

– access-backhaul integration

› Seamless integration with wide area network at lower frequencies

– robustness, UDN as “data booster” layer

Ultra-Dense Networks

Connected Devices

› Sensor, actuators, meters, connected devices and things › Small, simple, low-cost › Low energy consumption › Long-range coverage › Connecting vehicles, transport infrastructure and transport management › Incl. safety-related services › Low delay › High mobility › Distributed embedded control & cyber-physical systems › High reliability and availability › Low delay › Autonomous operation

Critical Communication Meters and Sensors Intelligent Transport Systems

LTE for meters & sensors ?

› Are LTE devices simple?

– high requirements on M2M device

› Are LTE devices well reachable?

– MTC devices may have unfavorable attenuation (basements, metal enclosures) – stationary MTC devices affected in particular

› Does LTE enable M2M devices to operate on battery for multiple years?

– not really

referring to LTE Release 8 with regard to the defined M2M requirements

Addressing Limitations

Reducing cost by up to 80%, eg by

– one receive antenna – data rates limited to 1 Mb/s – using 1.4 MHz BW only

Further enhancements

– half-duplex FDD – reduced RF bandwidth

Options for low-rate MTC devices

– repetition with energy accumulation – power/PSD boosting – relaxed performance requirements – simplification/elimination of physical control channel functionality or design of new channels/signals

Capillary GWs Connected Devices

› The majority of device connections predicted as short-range, non-3GPP

– e.g. Bluetooth Low Energy, IEEE 802.15.4 – but can only provide local connectivity at the edge

› Provide connectivity, security solutions and network management
