que é o 5G (Quinta geração de redes movéis celular).
Bem como apresentar alguns projectos de 5G.
E relacionar o 5G com a internet do futuro.
6. 5G Introdução
O que é o 5G ?
Janeiro de 2012 a ITU-R aprovou a especificação do 4G.
Enquanto isso o dramático crescimento dos serviços de dados
móveis desencadeou o estudo do 5G.
7. 5G Introdução
O que é o 5G ?
A industria ainda não chegou a um consenso sobre o que é o
5G.
8. 5G Introdução
O que é o 5G ?
Conjunto de padrões de comunicações móveis
interconectados.
Era 2020.
11. 5G Requisitos
(Boyd Bangerter, at IEEE Communications Magazine 2014) “The
industry’s concept of mobile performance is evolving, and so are
performance metrics”.
12. 5G Requisitos
Qualidade de experiência de Usúario QoE
(Boyd Bangerter, at IEEE Communications Magazine 2014) “In
order to provide a high QoE for services, 5G systems will need
to be context-aware, utilizing context information in a real-
time”.
13. 5G Requesitos
Maior Capacidade
(T. Nakamura, at IEEE Communications Magazine 2013)“Mobile
data traf-fic has been forecasted to grow more than 24-fold
between 2010 and 2015, and more than 500-fold between
2010 and 2020”.
14. 5G Requesitos
Maior Capacidade
(Woon Hau Chin, at IEEE 2014) “heavyweights such as
Qualcomm and Nokia Siemens Networks are looking at
technologies which will cope with traffic growth of 1000 times”.
16. 5G Requesitos
Maior Eficiencia Espectral
Tecnicas de Multiplo acesso Não Ortogonais:
GFDM Generalized Frequency Division Multiplexing.[8]
CDMA-FMT.[9]
17. 5G Requesitos
Mais Espectro
MmWave:
(Federico Boccardi, at IEEE Commnucations Magazine 2014)
“While spec-trum has become scarce at microwave frequen-
cies, it is plentiful in the mmWave frequencies ranging from 3
to 300 GHz”.
18. 5G Requesitos
Mais Espectro
MmWave.
Bandas que estão a ser estudadas:
(Federico Boccardi, at IEEE Commnucations Magazine 2014)
“28–30 GHz, the license-free band at 60 GHz, and the E-band
at 71–76 GHz, 81–86 GHz, and 92–95 GHz”.
20. 5G Requisitos
Menor Custo, Mais Flexibilidade
(Boyd Bangerter, at IEEE Communications Magazine 2014)
“Cost and flexibility of deployment will also be important factors
in 5G networks, requiring a shift toward software-based
implementations and virtualization technologies”.
22. 5G Arquiteturas Propostas
“At the moment, the wireless industry has yet to reach a
consensus on a unified view of future 5G network architecture.
Some favor a more distributed network architecture with self-
organizing capability, while others have advocated more
centralized cloud-based access networks”.
26. 5G Arquiteturas Propostas
Anchor-Booster
(3GPP TR 36.932, 2013) “In this architecture, the macro cell
operates as an anchor base station, and is primarily
responsible for control and mobility, while the small cell
operates as a booster base station and is mainly responsible
for offloading data traffic”.
27. 5G Arquiteturas Propostas
Cloud RAN
(China Mobile, 2010) “In scenarios where small cells can be
connected to macrocells with low-latency high-rate (“ideal”)
backhaul, the baseband signals from several hun-dred cells
can be received and processed at a centralized server
platform”.
28. Tecnologias Propostas
(Boyd Bangerter, at IEEE Communications Magazine 2014)
“Several technologies expected to be key ingredients of 5G, ...
are available today. Many others will be developed and deployed
over the coming years.”
30. Tecnologias Propostas
Small Cell
(Woon Hau Chin, at IEEE 2014) “By reducing the size of the
cell, area spectral efficiency is increased through higher
frequency reuse, while transmit power can be reduced such
that the power lost through propagation will be lower”
31. Tecnologias Propostas
Small Cell
(Woon Hau Chin, at IEEE 2014) “Additionally, coverage can be
improved by deploying small cells ... and offloading traffic from
macro cells when required”
32. Tecnologias Propostas
Small Cell
(Shanzhi Chen, at IEEE Communications Magazine 2014) “the
increase of small cell numbers in the future may far exceed
100 times the current number”

(Boyd Bangerter, at IEEE Communications Magazine 2014) “An
integrated virtual radio network will enable joint management
and simultaneous use of radio resources across different radio
technologies to significantly improve radio capacity, and
enhance coverage and wireless link reliability”.
35. Tecnologias Propostas
M2M
(Boyd Bangerter, at IEEE Communications Magazine 2014) “the
Internet of Things concept contemplates a world where
everything from alarm clocks to washing machines to automo-
biles is connected through mobile-based machine-to-machine
(M2M) communications”.
36. Tecnologias Propostas
Massive MIMO e 3D MIMO
(Boyd Bangerter, at IEEE Communications Magazine 2014)
“Advanced multiple-input multiple-output(MIMO) techniques are
at the heart of achieving higher capacity for cellular systems.”
37. Tecnologias Propostas
Context Awareness
(Boyd Bangerter, at IEEE Communications Magazine 2014) “In
order to provide a high QoE for services, 5G systems will need
to be context-aware, utilizing context information in a real-time
manner based on network, devices, applications, and the user
and his/her environment”.
38. Tecnologias Propostas
Context Awareness
(Boyd Bangerter, at IEEE Communications Magazine 2014) “In the
5G Era, new ways to abstract and efficiently generate context
information are needed, as well as new ways to share context
information between the application, network, and devices”.
39. Tecnologias Propostas
Software Defined Celular Networks
(Woon Hau Chin, at IEEE 2014) “Recently, there are also growing
interests in both academia and industry to apply SDN to mobile
networks”
40. Tecnologias Propostas

infancy. There are a number of outstanding issues to be resolved
before it can realize its full potential”
41. Tecnologias Propostas
