A Network slice is a logical network serving a defined business purpose or
customer, consisting of all required network resources configured together.
It is created, changed and removed by management functions

Immersive experience
Singtel welcomes F1 to Singapore
"With Sports Plus on Singtel CAST, race fans will
be able to catch the entire high-velocity night race
from wherever they are, even around the high
traffic areas of the circuit, where over 250,000
spectators are expected, due to the dedicated
capacity being allocated to the service."
"Our CAST app gives race fans full visibility of the
track action by enabling enhanced lag-free and
high-definition content streaming while locals and
tourists can enjoy other digital experiences from
making video calls, augmented reality gaming
and more with 5G - bringing greater fun to the
festivities.”

Live Video Production
DT and RTL Deutschland partnership
"Thanks to 5G Standalone, the entire TV technology for a
live broadcast will fit in your pocket in the future. This 5G
solution will revolutionize mobile journalism."
"Relevant journalism is highly up-to-date and particularly
happens on the go. This is especially true for breaking news.
Real-time video with 5G makes these mobile TV reports
even more accessible. In our tests, Telekom's 5G standalone
network was able to exceed the high demands of TV
operations in terms of signal transmission. The network is
secure and reliable. And this innovation ties in seamlessly
with the use of smartphones. It enables our journalists to
focus even more on what counts: reporting independent
news from any location at any time.”

Fixed Wireless Access
Verizon sees FWA as the next generation of broadband
Reliability
"The 5G-fueled version of Verizon's fixed wireless access
(FWA) service is being used as the primary use case for
about 80% of the company. It's not a secondary backup“.
“Cable’s outside plant issues can take days to resolve, a
particularly critical issue in B2B, where Cable has had a
growing presence,
Guaranteed QoS
Existing network functionality such as QoS differentiation or
RAN slicing should be used to separate mobile broadband
from FWA traffic using the same spectrum, in order not to
jeopardize mobile broadband quality as FWA traffic grows.

Reimagining business possibilities without limits on location
"MPN is tailored to your requirements – addressing your
connectivity and speed needs now and in the future. MEC
also offers the same flexibility as the public cloud, which
traditionally allows users to scale up or down the computing
power that they need."
"China Mobile began commercial operation of the world's
first 5G SA Shared MPN with end-to-end network slicing and
Public MEC in September 2019 for China Southern Power
Grid Co.
As a result of this head start, Chinese MNOs have quickly
ramped up to monetize MPNs, with literally thousands of
networks generating new revenue streams.”
