4 Local High-Quality Wireless Networks
4.0 Introduction
The next generation of broadband mobile communication networks aims to integrate applications of vertical sectors in
its holistic ecosystem of enabling technologies, spectrum management frameworks and networking paradigms. To make
this happen, key requirements of vertical sectors should be communicated, properly discussed, and finally reflected
within the relevant design and standardization processes.
Clause 4 of the present document analyses the communication requirements of selected vertical sectors, e.g. Industrial
Automation, Utilities, Culture and Creative Industry, PPDR, e-Health, etc. The analysis will identify a set of use cases
typically demanding predictable Quality of Service (QoS) levels at all operation times, within short-term to long-term
deployments in local environments. As well, the set of identified use cases favour private network infrastructure and
own management functionality for implementing specific security standards or simply due to privacy reasons.
Based on this analysis, the concept of local high-quality wireless networks is proposed as a collective term to enclose
that kind of use cases.
4.1 High Level Use Cases and Requirements
4.1.1 Programme Making and Special Events (PMSE)
4.1.1.1 General
Programme Making and Special Events (PMSE) is a term denoting wireless applications used to support broadcasting,
news gathering, audio and video production for film, theatre and music, as well as special events such as sport events,
culture events, conferences, and trade fairs.
The PMSE industry delivers key enabling equipment for the culture and creative industries, both having a significant
socio-economic impact in the EU.
Typical PMSE equipment includes for example wireless microphones, in-ear monitors, video cameras, conference
systems, light and remote controls.
Wireless audio PMSE equipment (e.g. wireless microphone, in-ear monitors, conference systems) employ digital or
analogue wireless technologies, which are specific, typically link-based developments of the PMSE manufactures to
support reliable, very low latency audio streaming transmissions required by the targeted professional audio
applications.

4.1.1.2 Use Cases and Requirements
4.1.1.2.0 General
This clause introduces three representative high-level use cases (UCs) of the PMSE industry and their requirements:
• Use case 1 (UC-1): Live Performance
• Use case 2 (UC-2): Presentation
• Use case 3 (UC-3): Tour Guide
For each UC, a short description is provided, as well, its major requirements as defined and used in the German
research Project PMSE-xG [i.1] are discussed.
These three UCs highlight two key aspects of wireless audio productions: low latency and high reliability. As such, they
can be grouped into a use case class (UCC) addressing low latency and high reliability audio streaming applications. As
a general requirement for this UCC, all wireless mobile devices need to be synchronized inside one local high-quality
wireless network.
4.1.1.2.1 UC-1: Live Performance
The use case 'Live Performance' involves several wireless microphones (handheld or body-worn) used to capture the
singers voice or the sound of instruments, several stereo in-ear monitors (IEM), at least one mixing console and a PA
system.
A typical scenario is for instance a concert, where an artist on stage is using a wireless microphone while he is hearing
himself via the wireless IEM system. The audio signal coming from the wireless microphone is streamed to one or more
mixing consoles, where different incoming audio streams (e.g. from different music instruments, choir) are being
mixed. After mixing, several audio streams can be generated, e.g. PA mix, individual IEM mixes for the artists or
recording mixes. From those, IEM mixes are wirelessly transmitted to the artist and musicians while most of the other
mixed signals are streamed via wired connections.
Depending on the type of event, the number of active wireless audio links or the data rates of the respective wireless
audio streams may vary. However, the requirements regarding latency and reliability remain principally the same for all
kind of live events/productions. Reliability is an essential feature because during live productions one cannot afford
repeating audio transmissions until it is error-free. Low latency is an essential feature because in this use case source
and sink of the audio transmission can be co-located, think of an artist equipped with wireless microphone and IEM.
Because the artist receipts audio of the environment also via its cranial bone, very low end-to-end delay (i.e. from the
wireless microphone to the mixing desk back to the IEM) is tolerated.
Table 1 summarizes the KPIs of the use case Live Performance.

PER The PER of the system is required to be below 10 for a packet size of 1 ms. Depending on the error
concealment the following exemplary error distribution may be tolerable:
• maximum continuous error duration = 30 ms
• consecutive minimum continuous error-free duration = 100 ms

4.1.1.2.2 UC-2: Presentation
In the use case Presentation, a presenter on stage is using a wireless microphone for example to present a slide set to the
audience. The wireless microphone is used for streaming the presenter's voice to the loudspeakers installed in a
conference room. When using more than one wireless microphone a mixing console is added, which mixes the
incoming audio streams to one or more output audio streams. One of these outgoing audio streams may be distributed to
the loudspeaker inside the conference room, another via Ethernet to several clients of the audio distribution network. In
this use case, no IEM is required, which relaxes the requirement on end-to-end latency.
Low latency and high reliability of the wireless link are essential for the use case, so that the assisting playback via the
loudspeakers is not irritating the audience or the moderator by distortions or not matching auditive-visual impression.
Table 2 summarizes the KPIs of the use case Presentation.
Table 2: KPI Requirements for the UC-2: Presentation, as described in [i.1]
KPI Requirement
End-to-end delay < 10 ms
User data rate 150 kbit/s - 1,15 Mbit/s
Control data rate ≤ 50 kb/s
Data rate per control link

PER The PER of the system is required to be below 10 for a packet size of 1 ms
Number of audio links 5 - 10 simultaneous
2
Event area ≤ 10 000 m , indoor and outdoor
Mobile user speed ≤ 5 m/s
Security Encryption of the user data

4.1.1.2.3 UC-3: Tour Guide
In the use case Tour guide, a guide is guiding a group of visitors being in close proximity. One can think for instance of
a conducted tour in a factory site, museum, sports venue or a guided city tour. The guide speaks to a wireless
microphone and the audio is distributed to the receiving head-sets of the visitors, so the distribution of the spoken
information from the guide to the audience while walking from spot to spot is in focus. Nevertheless, one can imagine
interactions between guide and audience in the form of questions and answers turning the tour guide system in a mobile
conferencing solution.
Low latency and high reliability of the wireless link are essential for the use case, so that the assisting playback via the
headphones is not irritating the audience or the guide by distortions or not matching auditive-visual impression. Here, at
least one multicast audio link (from the guide to the visitors) should be supported, and up to ten unicast audio links
(from the visitors to the guide) are necessary.
Table 3 summarizes the KPIs of the use case Tour guide.
Table 3: KPI Requirements for the UC-3: Tour-Guide, as described in [i.1]
KPI Requirement
End-to-end delay < 10 ms

4.1.2 Wireless Industrial Automation (WIA)
4.1.2.0 Introduction
Industrial communication has fundamentally different requirements to conventional commercial communication.
Essentially, industrial communication is used to control and monitor real-world actions and conditions concerning
specific physical equipment, while the primary function of commercial communication is data transfer and processing.
Industrial communication has a broad range of use cases and deployment scenarios with a unique set of requirements on
the communication latency, reliability, availability, and throughput. The isolated application and heterogeneity of
wireless communication systems in existing industrial deployments can be mainly attributed to the following three
reasons:
i) challenging propagation and channel conditions with strong fading and multipath effects;
ii) no determinism for channel access; and
iii) extreme requirements in terms of very low latency and high degree of reliability.
4.1.2.1 Industrial Communication Requirements
4.1.2.1.0 General
Many of the industrial application use cases have extremely high requirements on the communication system. Figure 1
shows a comparison between mobile broadband and industrial communication. As illustrated, industrial communication
has particularly high requirements in terms of high reliability and low latency. Please note that requirements on high
reliability and low latency in industrial applications typically come hand in hand, i.e. extreme values for both metrics
are needed at the same time. Other distinguishing factors include device density, relatively small packets with very short
inter arrival times, and high data rates that further increase the requirements in industrial communication. Moreover,
dependent on the use case there is a need to support very high communication distances such as in process aut
