Single anchor points to external networks (PDN-GW)
Hierarchical network means non-optimal traffic routing
Heavy signalling load
Increasing CAPEX/OPEX Increasing operations &
management complexity Efficiency in usage of radio
resources
Solution: Distributed & virtualized
network architecture Network slicing
Solution: Convergence of network
infrastructures Network Softwarization &
SDN
Impact of LTE so far • For 2015, Smartphones represented 43 percent of total global handsets, but
represented 97 percent of total global handset traffic. - Smartphone generated 41 times more mobile data traffic than the typical
basic-feature cell phone. • A LTE (4G) connection generates 6 times more traffic on average than a
non-4Gconnection. - In 2015, 4G connections represented about 14 percent of mobile
connections, but generated 47 percent of mobile data traffic. • Network connection speeds increased by 20% in 2015.
- Average mobile network downstream speed in2015 was 2 Mbps, up from 1.6Mbps in 2014.
• Mobile video traffic accounts for over 55% of total mobile data – LTE speed has been a big enabler for this - Video expected to continue to be a big growth driver

5G Solutions • IMT-2020 solutions will focus on addressing the following
areas:
© Orbitage 2016 slide 11 5G Network Challenges
Supporting very low latency and high reliability human-centric communication
Supporting very low latency and high reliability machine-centric communication
Supporting high user density
Maintaining high quality at high mobility
Enhanced multimedia services
Internet of Things (IoT)
Convergence of applications
Radio: How to Achieve Higher Speed?
Higher Speed
MIMO Antennas
Higher Order
Modulation More
channel bandwidth

Bottom line: Need better SNR
Deployment Challenges
(space/freq, cost)
Diminishing returns: complexity
vs rate
Regulatory control &
use of higher freq
Support for High Freq Bands • 5G is looking at the technical feasibility of IMT in bands
above 6 GHz (6-100GHz) • Expected that these frequency bands will not be used
for primary communications, but rather as secondary carriers when the radio propagation conditions are suitable
• Looking at covering a range of different application areas: - Line-of-sight and non-line-of-sight - Stationary and mobile - Outdoor-to-indoor
• Solutions will be based on MIMO and beamforming with a large number of antenna elements

Current Cellular
O2 absorption
H2O absorption
Huge blocks of spectrum available for short range outdoor/indoor access
Need to take into consideration existing microwave backhaul bands Offers high peak bitrates for users in suitable locations Won’t really improve cell edge bitrates
Non Radio Considerations
Quality of Service
• Ensuring that users get a “Quality of Experience” while maximising efficiency
• Diversified services managed simultaneously
• Low latency backhaul required
Fronthaul Capacity
• Optical interconnect between base stations & active antenna systems
• High capacity demands
• Early standards include CPRI not up to the job
Network Softwarization
• Virtualization of networks & network components
• Management & orchestration of networks dynamically & flexibly via SDN
• Continued/ extended SON for radio
