5G antennas will be installed on approximately 210,000 traffic lights nationwide. They will support traffic lights and antenna base stations as emergency power sources during power outages.
The "LioUPS3" is an outdoor uninterruptible power supply that achieves a wide operating temperature range and long lifespan by adopting high-performance lithium-ion batteries.
Among approximately 210,000 traffic signals maintained, operated, and managed by prefectural police, it is said that about 30% (as of summer 2019) are connected to a network. Expectations for the expansion of centralized control areas for traffic signals using 5G and for achieving safer and smoother traffic in anticipation of a self-driving society are increasing.
5G, characterized by high speed, large capacity, ultra-low latency, and numerous simultaneous connections, is set to begin deployment, with partial operation expected to start in 2020. Because 5G uses higher frequencies than before, denser base station installations will be necessary. For these reasons, the construction of a 5G network utilizing traffic signals is about to begin.
In recent years, power outages caused by natural disasters such as typhoons, heavy rain, and earthquakes have led to traffic signals losing power and antenna base stations going offline, affecting social life by disrupting mobile phones and smartphones.
In such times, Seiwa Electric's outdoor uninterruptible power supply is essential.
