By Zhang Hongguan & Zhang Yufeng Uninterrupted power supply for remote base stations has been a challenge since the founding of the wireless industry, but alternative sources have a chance of succeeding where traditional solutions have failed.
For base stations, there are six power supply combinations-solar-only, solar+diesel, solar+mains, etc. Solar-only When there is sufficient sunlight, photovoltaic cells convert solar energy into electric power. Loads are powered by solar energy controllers, which also charge the batteries.
When sunlight is not sufficient, the batteries will take over. Considering that remote base stations must be highly-integrated, inexpensive, and modest, Huawei has developed its all-on-pole EasySite solution, which integrates the base station, antennas, transmission, and tower into one convenient package.
However, charging of onsite batteries is time-intensive. Frequent power outages lead to frequent discharging and incomplete recharging, which dramatically shorten battery service life, while frequent start-up and shut-off of diesel generators wastes fuel, generates noise and leads to more frequent breakdown.
