17. 5G Technologies

18. Drivers For Next Generation (5G)
Growing Population
Hyper Connectivity
Limited Resources
Higher Capacity
Green Technology
Cost Efficiency
Quality of Experience
Number of connections and also the volume of data over
wireless networks continuously growing at a significant rate
Users more demanding on quality & price
Capacity challenge is real particularly in radio
Radio spectrum the blood line of wireless is a finite resources,
scarce and expensive
The data volume growth will continue but dependent on the
service quality offered by the NW and of course the data tariffs
Sustainability of mobile broadband business - Ever increasing
traffic, higher TCO and flattening ARPU
3G & 4G both promised improvements in NW capacity, data rate,
efficiency, cost and quality. 5G will be no exception but the sheer
scale of the challenges this time makes 5G research different.
Dr Shahram G Niri, July 2014 18

19.  Values subject to assumption
 Modest increase in number of devices and usage
 Traffic growth: ~70% CAGR
 In 2020 depending on the environment
traffic per km2 (1.5 to 60 Gb/s/km2)
 UK needs at least ~ 15 - 20 x capacity (2013-2020)
 Current LTE technology will not accommodate the
predicted traffic growth
The next generation will need to be designed
not for 2020 but for 2025-2030 capacity

20. Significant air interface capacity
-Focus on area NOT JUST link spectral efficiency
-Designed for small Cells (capacity), extended to coverage
-More spectrum (Licensed & unlicensed operation, spectrum
sharing & other sources)
Super low latency
- Sub 1 ms, TTI: 10-25 ms
-Faster signaling for higher data rate, in line with data rate
-U plan latency: frame structure, control signal timing, HARQ
-For new services (MTC, gaming, ….)
-For distributed control
Super reliable
-For new services and applications
-Smart transport, e-health, intelligent control, …
The higher capacity and lower latency necessary for wide
range of services BUT not all the services required in the
same location, at the same time nor by the same air interface
May need tradeoffs in
capacity, coverage and data rate

Greener Telecom Lower CTO
Greener technology (energy efficiency)
-Current 2% ICT share of CO2 emission is likely to increase
-Power consumption doubled in past 5 years
-More power efficient HW & SW, needed
-Reducing signaling through intelligent O&M and SON
-Alternative energy sources
Reduced Total Cost of Ownership
-For x1000 need to achieve 1/1000 delivery cost per bit!?
-Deliver cost will need to be recalculated as cost per bit/km2
- Saving through energy consumption
-Saving through lower cost of operation (Plug & Play, Self
managed NW, Zero touch)
-Spectrum and infrastructure sharing
-Longer HW life cycle time
-New business models -> new revenue models

technologies
• 5G will change the system architecture, especially the RAN
• A much denser network (small cells) will be key to 5G
design
• Spectrum remains a challenge for the wireless industry;
spectrum sharing will be critical
• A greater degree of network sharing may be needed in 5G
