Hi, I see that variants of this question has been asked a few times in the past, but I'll give it a shot too. I work for a civil engineering firm that does a lot of public works projects for a (very) small country. Recently we have been approached by the government and investors to help start a new network operator to provide wireless services. Our firm wants to seize this opportunity, but where to begin? We are experts in physical infrastructure engineering but have no experience in wireless. Setting aside the business and politics of starting a network operator (that's someone else's department), what are the fundamental engineering questions that need to be asked to get started here? What are the very specific engineering disciplines I need to be hiring for (please don't say "telecom engineer"). Thanks!
