introduced Ericsson Uplink Booster solution at an online press conference on
on unprecedented data processing speed and ultra-low latency requirements, 5G optimizes
and processes large amounts of data for various service purposes than any
previous generation technology. Stable 5G coverage and performance are more
important than ever in the evolution of 5G including SA and the demands of the
market. Ericsson Uplink Booster provides connectivity for various 5G services
with differentiated 5G architecture and sophisticated reception algorithm.
Uplink Booster is based on the eCPRI industry standard and applies the optimal
physical layer segmentation option. The beamforming processor was implemented
on the radio unit rather than on the digital unit (DU) to minimize the data
processing capacity through the front hole. Through this, beamforming
performance is maximized by processing radio channel information faster and
more accurately. Therefore, 5G coverage dependent on uplink is also extended at
the same time.
order to provide a stable 5G service, it is important to secure downlink and
uplink coverage simultaneously for service users or terminals. In particular,
it can be said that in the case of high-resolution CCTV or autonomous vehicles
that require large-scale uplink data transmission, securing uplink performance
A self-test conducted in Sweden by turning the uplink booster on and off showed 90% app coverage improvement and uplink performance improvement. In addition, the benchmark test conducted in a commercial network in North America confirmed that the uplink performance difference was confirmed.
