5G SA is the next phase of next-gen
Deutsche Telekom completed the Czech Republic’s first 5G Standalone (SA) trial
in Pilsen. During the trial, the two companies verified the performance of 5G
SA Multi-User, Multiple-Input Multiple-Output (MU-MIMO) technologies using
Samsung’s massive MIMO radio and core.
The results from
the trial, according to the companies, showed that the spectrum efficiency was
tripled in comparison to that of LTE under realistic conditions, while
throughput increased by about 2.5 times of Single-User MIMO.
Nearly all of
the current commercial 5G networks around the world use a non-standalone (NSA)
architecture wherein new 5G NR radio infrastructure is connected to an Evolved
Packet Core that also supports LTE data transmissions. With NSA 5G, the
emphasis is on delivering enhanced mobile broadband to consumers, but the 5G SA
architecture enables mobile operators to have more efficient network
operations, while enabling them to offer new, immersive user experiences and
enterprise business models.
operators are hoping to leverage standalone 5G to deliver network slicing,
or an end-to-end logical partition of a network that provides specific levels
of service in an autonomous fashion. Ideally, the end user gets the needed
connectivity, and the operator provides a differentiated service in a manner
that optimizes use of network and spectrum resources.
Samsung, its 5G core, used in the Czech Republic trial, “can effortlessly
create multiple network slices in a single physical network infrastructure.” In
mid-December, Samsung achieved a 5G SA core data processing capacity of 305
Gbps per server during a demonstration with
“Samsung is glad
to successfully conduct the first Massive MIMO call on an end-to-end 5G
architecture within the DT Group in Europe. This is an important milestone in
both companies’ efforts to bring 5G to the next phase,” said WooJune Kim,
executive vice president and head of global sales & marketing, Networks
Business at Samsung Electronics.
with Deutsche Telekom should go a long way in securing a stronger European
foothold for Samsung, which has been lagging somewhat behind rivals Nokia,
Ericsson and Huawei in the region.
