Sizing the Total Bill for a Wi-Fi Deployment in New York

Put a price on setting up Wi-Fi in New York. Show how you structure the estimate, label each assumption, and finish with a figure and a range. ```hint Find the count that drives cost Decide which quantity the cost scales with under your reading of the question, and check that count from two angles before multiplying it by a unit cost. ``` ### Clarifying Questions - Does "Wi-Fi in New York" mean a public network covering streets and public spaces, or getting Wi-Fi into homes and businesses? - New York City or New York State? - Is only the one-time setup cost wanted, or also the cost of running the network each year? - May the build reuse existing assets such as street fiber, streetlight poles and former payphone sites, or must it pay for all of them? ### What a Strong Answer Covers - An agreed reading of "Wi-Fi in New York" and of the geography, settled before any arithmetic - A cost equation split into equipment, installation and the connections that carry traffic back to the internet - Labeled, round assumptions, each with a short rationale - Arithmetic that is correct and unit-consistent, with the main count justified rather than asserted - A sanity check from a second angle, a final range, and the inputs that move it most ### Follow-up Questions - How would the estimate change if the network also had to work inside buildings or in the subway? - What would the network cost to run each year, and who might pay for it? - Which assumption would you check first, and where would you find the data?
