Is 5G just about more data – faster, better, cheaper LTE?
•Ofcom report shows significant
demand from UK consumers for
broadband data, with residential
fixed-line broadband customers
using on average 17 GB data per
month. By comparison, mobile
broadband demand averages 0.24
GB per month per connection

Cellular evolution will not support all M2M applications
• Cost • Whole range of applications open up as cost reduces (1,000,000,000X
variation in bit value!)
• Power consumption • 1,000,000X variation in power available
• Coverage
• Many apps will need universal coverage, others only limited areas • Smart meters – need to penetrate every basement, every cupboard
• Location accuracy
• Many apps involve a location element • Big variation in required accuracy – eg traffic management and surgical
instrument location!
• Quality of Service • Voice, video – require guaranteed streams • Other apps send 1bit/day (eg vending machine)

What is 5G?
► From this year’s Mobile World Congress:
NSN’s head of technology and innovation, Hossein Moiin. “I have
no idea what 5G is. It will be defined in the future. What we do know
is what direction it will take.”
Mari-Noëlle Jégo-Laveissiere, head of innovation, marketing and
technologies division, Orange. “[Whatever 5G is], it should not be
4G-plus one,”
The general consensus among companies ……it will be user-
centric, more dynamic and energy efficient, and will use all types of
frequency bands. … it will pervade all areas of life as it embraces
new services from the Internet of Things, M2M through to business-
critical applications.
And it will arrive after 2020…………..

Talking point 1 - Do we need a “special solution” for M2M?
© British Telecommunications plc
Data rates are only high near the base
station….
Capacity is shared….
Core

Tomorrow Small cells,
high capacity & data rates
Mobile networks will need to get closer to the
user

Today Large cells,
medium capacity & rates
Talking point 2 – is 5G just smaller cells?

Talking point 3 – where will the spectrum for 5G
come from?
