[One of the problems with the spread of local 5G networks]
When building a local 5G network (Private 5G) in mountainous areas, ships, islands, rural areas, etc., it is necessary to have an internet connection to the local 5G network for i) remote monitoring and collaboration at the headquarters, ii) access to the cloud for work, and iii) maintenance of the local 5G network.
However, these areas are often sparsely populated, and Internet connections provided by existing carriers or telcos are not available.
[Japanese industry solution: low-orbit satellite Internet]
To digitally transform a dam construction site in a mountainous region, Japanese construction company Ando Hazama introduced a local 5G network to the site and used a low-orbit satellite internet link from US-based Starlink to connect the local 5G network to the Internet.
In October 2023, Ando Hazama Construction and the University of Tokyo conducted a demonstration test at a dam construction site in a mountainous region, using a local 5G network and the Starlink satellite Internet network to efficiently manage construction and safety on site, including communication with construction personnel and remote monitoring.
Dam Construction Site: Starlink satellite antennas and a local 5G system were installed at the site office located at the foot of the mountain.

This is a very practical example of combining Private 5G with LEO satellite connectivity to overcome the limitations of remote construction sites. One additional improvement I would suggest is deploying an edge AI platform at the local MEC to analyze video streams and sensor data before sending only relevant events over the satellite link. I believe this would reduce bandwidth usage, geometry dash lite, minimize latency, and ensure critical alerts remain available even during temporary satellite connectivity fluctuations. Thanks for sharing such an insightful real-world deployment.
