5G Applications
13. eMBB applications generally involve humans accessing multi-media
content, services and data
High data rate scenarios at offices, shopping centres, urban streets and
residential locations. This use case family includes the broadcast of
audio and video, e.g. 4K ultra high definition video. Deployments at
residential locations should be capable of competing with fixed
broadband services.
Femtocell deployments at office, residential and urban locations to
provide a 5G air-interface with a fixed broadband backhaul.
high density scenarios to support the transfer of high data volumes per
unit area, e.g. at offices and other hotspot locations including shopping
centres, urban streets, stadiums and public transport

massive Machine Type Communication (mMTC) is characterized by a very large number
of connected devices which typically transmit low volumes of non-delay sensitive data.
mMTC devices are generally required to be low cost and have a long battery life. main
categories of application are:
Internet of Things (loT) with a large number of devices transferring small volumes of non-
time critical data.
Smart Wearables (personal area network) using low complexity devices with a long battery
life.
Sensor Networks used to monitor a wide range of metrics, e.g. traffic. weather, parking spaces.
Many existing loT devices do not use a cellular network. e.g. devices using WiFi to connect
to the internet via a wirless router. These devices are typically short range, have little or no
mobility, Bluetooth Low Energy (BLE) and ZigBee are other alternative wireless technologies
used to connect loT devices lo each other and to the internet.
Within the context of 5G, the main focus is upon 'cellular loT' devices which use 5G as the
access network. Cellular loT devices benefit from the ubiquitous wide area coverage provided
by a mobile operator. These devices may support applications which involve mobility and
they do not depend upon the availability ofa wireless router.
The Smart Wearables category includes activity tracking devices, personal sensors.
augmented reality headsets, smart watches, smart ear buds, smart glasses and identity
wristbands for admission into theme parks. Most of these applications require mobility and
benefit from the wide area coverage provided by cellular networkscellul
Massive Machine Type Communications (mMTC)
15. Massive Machine Type Communications (mMTC)
Sensor Networks may form part of the Smart City ecosystem.
Sensors can be used to monitor traffic conditions and car
parking occupancy. These metrics can be used as inputs lo
generate recommendations for drivers. Sensors can also be
used to monitor environmental metrics such as air quality and
weather conditions. Weather conditions can be used as an input
for automatic street lighting or variable speed limits. Sensors
used for security applications can detect movement or apply
facial recognition.
loT devices may not connect directly to the mobile network. For
example, a smart watch may connect to a smart phone, and the
smart phone connects to the mobile network, i.e. the smart
phone acts as a relay device for the smart watch.
16. Ultra Reliable and Low Latency Communications (URLLC)
Higher Reliability and Lower Latency applications: this family of applications
requires low latency but does not require very low latency. For example, the
remote control of vehicles by a human operator has a latency requirement
which is determined by the human reaction speed.
Higher Reliability, Higher Availability and Lower Latency applications:
Industrial control applications can belong to this category. The remote
control of drones can fit into this family of applications. High availability is
important to ensure that the drone is always under the control of the human
operator.
Very Low Latency:this family of applications includes the concept of the
'Tactile Internet'. The Tactile Internet supports a remote extension to the
human body. For example, it allows a surgeon to remotely operate on a
patient using a mechanical arm which reacts as though it was the surgeon's
own arm.

Slice = A logical network serving a particular
application, business partner, or customer
Similar to Virtual Machines (VMs) on a computer
A network can be divided in to many slices
Each slice looks to the user as a separate network
with reserved resources .

33. Beam forming uses multiple antenna elements to generate a beam
of radiated power in a specific direction
The physical size of an antenna array depends upon the carrier
frequency. Antenna arrays are typically designed using half-wave
dipoles.
At 3 GHz this corresponds to 5 cm, whereas at 30 GHz it corresponds
to 5 mm. The reduced size means that antenna panels with a large
number of antenna elements are more practical at the higher
operating bands.
Beam forming typically involves steering the antenna beam pattern
towards a specific UE. This can be achieved by applying delays (phase
shifts) to each of the transmitted signals. This means that each
physical antenna element transmits the same signal but with a
different delay.
