Site power supply has always been an issue for base station deployment projects. For both rural and urban scenarios, there exist different difficulties:
For Rural Areas
● Far away from grid facility, hard to get power resource
● Highly relying on Diesel Generator, resulting in several problems
– High expense on fossil fuel;
– Air pollution;
– Security issues: stealing fuel happened in remote areas
● High labor cost: it is expensive for an engineer getting to the sites.
For Urban Areas
● City electricity supply is not stable in most of developing countries.
– For example, in Pakistan, enterprises suffered from power failure 75 times in one month.
● Limited space for power supply equipment
● Security concerns: requirement on video surveillance, remote management system
