It really depends on the current environment. If you are converting an existing street light the Luminetworx™ can use between 100 – 277 VAC to power the PoE switch. If you are using a centralized model for installation you would not install the PoE switch at the pole but rather in centralized outdoor electrical housing. Regardless of your situation the PoE Smart Pole infrastructure is very versatile and can adapt to your current situation.
