Current Mobile Network Issues
 Increasing CAPEX/OPEX Solution:
 Increasing operations & Convergence of network
management complexity infrastructures
 Efficiency in usage of radio Network Softwarization &
SDN
resources
 Circuit-like service on IP
network (GTP)
 Single anchor points to external Solution:
Distributed & virtualized
networks (PDN-GW)
network architecture
 Hierarchical network means Network slicing
non-optimal traffic routing
 Heavy signalling load
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:
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

(space/freq, cost)
Speed Bottom line:
Need better SNR

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

Using High Frequencies
3GHz 57 64 164 200 300GHz
Current O2 H2 O
Cellular absorption 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
Network
Quality of Service Fronthaul Capacity
Softwarization
• Ensuring that • Optical • Virtualization of
users get a interconnect networks & network
“Quality of between base components
Experience” while stations & active • Management &
maximising antenna systems orchestration of
networks
efficiency • High capacity dynamically &
• Diversified demands flexibly via SDN
services managed • Early standards • Continued/ extended
simultaneously include CPRI not SON for radio
• Low latency up to the job
