Mobile generations “appear” every 10years


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?


Data rates are only high near the base

station….

Capacity is shared….

Core

network

Tomorrow Small cells,

high capacity & data rates

Mobile networks will need to get closer to the

user

Core

network

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?

(top), near Heathrow airport (middle) and in central

London (bottom) - source - Ofcom


Talking point 4 – will 5G use spectrum sharing?
