Hi fellas! I am planning to start a ISP in our region, which uses cellular tower for bandwidth signal receiving & transmitting. We have established the leased line back bone to our network and figured out microwave & GSM antenna concepts to receive signals from suppliers and to send signals to customer. Also we have located a tower, and are in negotiations to rent it for our ISP service. But, there are some details, which impedes us from proceeding further. Hope you fellas can answer it, I am listing down the questions below. Looking forward to your expert replies to it. 1. Is there any specific spectrum in which we have to operate the broadband service and is license necessary for using that spectrum? 2. How do we monitor the customers who will be using our wifi signal (any system server, which we have to maintain)? 3. Other than tower, antennas and leased line for back bone, what are the other equipments required to operate the ISP? 4.How do we bridge the connection between our supplier(who provides the internet) and our customers(who will be using our service)? What are the equipments used and core concepts involved in it? 5. Can someone brief about the routing/switching platform concept and the equipments used? Looking forward to your answers. Thanks for your time!
