What can we do when we are going to install a mobile signal repeater but there no power on site?

There are a few options to consider if you are planning to install a mobile signal repeater but there is no power on the site : 

Alternative power source : explore alternative power sources to run the repeater , here are some possibilities : 

Solar panels : a solar panel system with batteries can provide sustainable power for the repeater . 

Generator :a generator can be used as a temporary or permanent solution . but consider noise and fuel availability . 

Battery power :if the repeater has low power consumption ,a large capacity battery might be an option for short-term use . 

Repeater with PoE(power over Ethernet ):if available ,consider a repeater model that supports Power over Ethernet (PoE),this allows the repeater to be powered through an ethernet cable connected to a PoE switch with a power source elsewhere . 

Relocate the repeater : if possible ,can you relocate the repeater to nearby location with a power suorce ?this might extend the coverage area but may not be feasible depending on the situation . 

Consult a professional : for complex scenarios ,consulting a professional installer experienced with off-grid setups is recommended .they can assess your specific needs and recommend the most suitable solution .
