Introduction
•
In this contribution, we discuss the direction of the next generation WLAN (i.e.
post-be) from a network operator perspective.
•
Wi-Fi and 6G mobile wireless will be integrated with each other to realize use
cases of next generation wireless access.
•
Use cases discussed in IMT-2030 and use cases that several companies proposed for post-be in
WNG SC have a commonality.
•
Note: the single system usage (i.e., Wi-Fi or 6G mobile wireless only) still exists.
•
Use cases not only for business to the customer
(B2C) but also for business to
business (B2B) should be covered in post-be.
•
After the formation of post-be SG, we should start discussing the inclusion of B2B use cases and
KPIs (key performance indicators) for creating PAR and CSD.

Wi-Fi markets for B2B from network operator's perspective
•
The Wi-Fi markets for B2B (significantly solution businesses and M2M / IIoT, etc) are
growing more and more in recent years, and products powered by Wi-Fi are essential
commodities for network operators.
•
Usages of B2B are treated as prominent use cases in 6G mobile wireless such as IMT-2030.

B2B oriented
Considerations on proposed use cases and KPIs
•
The performance of those use cases is evaluated by several KPIs that are not only
throughput but also various aspects such as latency, reliability, and power
consumption, etc.
•
Though Wi-Fi has been developed as a high-speed local area network historically, it is now one
of the dominant wireless access that can realize various attractive use cases and applications.
•
Those use cases are classified roughly into B2C oriented or B2B oriented.
•
For example, AR/VR/XR, video, cloud gaming, and P2P tend to be B2C. On the other hand, IIoT
and robotics are considered to be B2B.
•
Though the major market segment of Wi-Fi is B2C until now, the importance of
B2B for Wi-Fi market will be increased in near future.

Slide 7

•
Essential use cases and KPIs
for IMT-2030 are discussed in
ITU WP5D.
•
The essential use cases and KPIs
of IMT-2030 almost correspond
to those of post-be.
•
The Wi-Fi systems should also
support some use cases and KPIs
from those, and it would
contribute to expanding the Wi-Fi
market if it could collaborate with
6G mobile wireless.
Requirements for 6G wireless technology [15]
Slide 8
Akira Kishida, NTT
July 2022
•
Drastic improvements in each KPI are
anticipated in 6G mobile wireless. However,
there is room for discussion on which KPIs
should be considered and how the target values
would be determined
in post-be SG.
•
As next-generation wireless access as a whole, those
KPIs and those target values should be achieved by
integration of Wi-Fi and 6G mobile wireless.
•
In post-be SG, we should discuss the above, and
the concrete target value of each KPI should be
clarified in the PAR, not like the case of TGbe.
•
In TGbe, a concrete target value of worst case latency
had not been clarified in the PAR.
Extract of EHT PAR [16]:
This amendment defines at least one mode of
operation capable of improved worst case latency and jitter.

Slide 9
According to the timeline proposed by contributions from several
companies,
the post-be standard would be published before IMT-2030
.
To realize use cases for private networks earlier than IMT-2030 would
expand the market of Wi-Fi.
Summary
•
Use cases for B2B are discussed in WNG SC, in addition to use cases for
B2C, which are important markets of Wi-Fi.
•
Those use cases are common to 6G mobile wireless and are also discussed in organizations
such as ITU IMT-2030.
•
To build robust and flexible next-generation wireless access, integration of
Wi-Fi and 6G mobile wireless should be required.
•
Post-be SG/TG should include use cases for B2B as a scope to realize this,
and discussions on target KPIs and performance will be inevitable.
•
It should be indicated clearly in the PAR and CSD of post-be SG.
