Huawei, NTT DOCOMO Reach 5G Milestone
Huawei and NTT DOCOMO, INC. reached a milestone in their joint 5G trials by succeed- ing in high speed data transmission over a
distance of 1.2 km on the 28 GHz mm Wave spectrum.
The ;eld trial, which took place at Tokyo Skytree in
downtown Tokyo, was conducted in an environment
where a base station working over 28 GHz was located
at Tokyo Skytree’s viewing deck at a height of 340 m
above the ground, while user equipment was placed
on the roof of a shopping facility at Asakusa Station.
Under adverse conditions of a - 10 dBm penetration
loss which came from the window glass of the viewing
deck, the partners achieved more than a 4. 52 Gbps
downlink throughput and a 1.55 Gbps uplink throughput with a coverage range of 1.2 km.
Huawei’s 5G base station, which supports Massive
MIMO and beamforming technologies, is being utilised in these trials to support successful long distance
data transmission over 28 GHz. In addition, the 5G
core network and 5G mmWave test user equipment
(TUE) was provided by Huawei to enable an end-to-end 5G network. Visitors to this open ;eld trial experienced next generation video communication using a
Microsoft HoloLens over the end-to-end 5G network.
An immersive experience was created during the live-demo, with clear voice calls and smooth video footage
free of freezing being displayed.
Gan Bin, vice president of Huawei 5G Product Line
said, “This successful long distance live-demo on a 5G
mm Wave is a groundbreaking achievement in our joint
effort with NTT DOCOMO to build a fundamental 5G
commercial environment. It makes us more con;dent in
realizing the goal of commercializing 5G by 2020.”

High-Power Waveguide Isolators
S Band R-Band
S band through R Band waveguide isolators for space-limited
systems with output reflection (VS WR) monitoring. Matched internal
terminations with an RF sample port or detected voltage output to
monitor system mismatch conditions. The isolation function provides
inherent directivity without more complex coupling structures.
