This document discusses key challenges for 5G testing including wider channel bandwidths and greater data capacity, new spatial processing techniques like massive MIMO, higher frequency bands with increased propagation loss, increased reliability requirements for applications, and higher traffic demands for IoT. It also outlines different 5G network topologies including standalone 5G networks, non-standalone networks using LTE, and connections to existing LTE infrastructure.

Wi-Fi
The total shipments
of Wi-Fi devices
surpassed fifteen
billion in 2016.
2016: 7.4B World Population 2020: 7.75B
The number of
smartphone users is
forecasted to be 6.1
billion in 2020. In
2017, 2.6B (over one
third) of the world’s

“In order to facilitate migration towards 5G,
NGMN recommends that LTE/ LTE-Advanced^
and Wi-Fi, as well as their evolution, are to be
supported by the new 5G network design.”
5G will use more than one RAT optimized for
use cases and/or spectrum.

Why does public safety need 5G
• A primary goal of 5G is a 10x reduction in latency and
V2X communications but why do we need this
• We have this all right now – vehicles communicating
with people, with extremely low latency….you just
don’t know it
• It’s called the brake light (for drones it’s for LOS
visibility)
• Legacy lights are incandescent and LED are the next
generation but it’s more than just pretty

The light bulb
A typical incandescent brake light
turns on in 300 mS…that’s
300,000,000 nS
A typical LED brake light turns on
in 100 nS…that’s 0.0001 mS
At 65 mph a 299 mS time = 29.1 ft
People ask about 5G low latency
and why – what are the use cases
I’d say about 20ft

28. #IWCEOnlineConference ● 2
5G Test Challenges
• Wider Channel Bandwidths and Greater Data capacity
• New polarization and spatial processing Techniques
– Massive MIMO, Cooperative MIMO, Adaptive beamforming
• Higher Frequency Bands mean higher propagation loss
– 5 Meter free space loss of 75.3 dB at 28 GHz
– Loss through “Low-e” windows at 28 GHz can be as much as 25 to 60
dB
– Indoor drywall attenuation of about 7 dB
• Increased reliability requirements for applications such as
– Remote surgery
– Vehicle-to-everything (V2X) communications for self driving cars
– Critical Communications – Police, Fire, Ambulance
• Higher traffic demands
– Massive Machine Type Communications mMTC (IoT)
• Two development tracks
– New Radio NR-5G – no backwards compatibility
– LTE-5G – use and improve existing 4G infrastructure
