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.
Of the approximately 210,000 traffic signals maintained, operated, and managed by prefectural police, it is said that about 30% are connected to the network (as of summer 2019). There is an increasing expectation for the expansion of centralized control areas for traffic signals using 5G, aiming for safer and smoother traffic in anticipation of a self-driving society.
5G, characterized by high speed, large capacity, ultra-low latency, and numerous simultaneous connections, is expected to begin partial operation in 2020 as its deployment starts. Since 5G uses higher frequencies than before, a denser installation of base stations 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.
