Remote Area Access Network for the 5th Generation

5G-RANGE receives funding from the European Union Horizon 2020 Programme (H2020/2017-2019) under grant agreement n 777137 and from the Ministry of Science, Technology and Innovation of Brazil through Rede Nacional de Ensino e Pesquisa (RNP) under the 4th EU-BR Coordinated Call Information and Communication Technologies.

SLIDE 6

Main Objective

To provide reliable Internet access in remote areas using a innovative 5G mode at

an affordable price.

Technology Challenge

Capacity & Spectral Efficiency Mbps/Hz Energy Efficiency Bits/Joule & battery autonomy Deployment Efficiency Cost per Coverage & Throughput

SLIDE 9

Geographical Challenge

Ceara state, Northeast Brazil State population: aprox. 9M Fortaleza (capital): aprox. 2.7M Population Density

Fortaleza: 8.000/km2
Ceara (minus Fortaleza): 42/km2

SLIDE 10

The General Picture

SLIDE 11

Specific Use Cases

SLIDE 12

Requirements

Large Coverage

§ Low population density regions demands for large cells § 5G-RANGE target: 50 km

Broadband connection

§ Reliable and high quality broadband connection. § 5G-RANGE target: 100 Mbps @ cell edge

Mobility

§ Support for drones, cars and trains § 5G-Range target: 120km/h

SLIDE 13

Core Technologies

Built-in Flexibility into PHY layer.
Cognitive Radio at LINK layer
Spectrum sharing (TV White Spaces)
Low order MIMO (up to 4x4)

SLIDE 14

TV White Spaces

High correlation between

low population density and amount of unused tv broadcast channels.

Below 1 GHz spectrum
Good propagation range

SLIDE 15

Planned Field Trials

Field Test to be deployed in Santa Rita do Sapucaí:

§ Coverage § Throughput § Robustness § Mobility

SLIDE 16

Final Messages

5G can overcome the last frontier for universal Internet access.
Challenging requirements (performance, cost) for remote areas can

be matched by 5G-RANGE combined set of core technologies.

Satellite and fiber are complementary, not competing technologies.
Field tests are necessary to confirm laboratorial/simulation-based

evaluations.
