Looking for best practices and feedback on whether to use fiber or radio ("air fiber") in a certain situation ...
=== BACKGROUND ===
--- Project involves providing Internet access to several hundred endpoints in a residential/campus type of setting (approx 50 acres)
--- Endpoints will have a WiFi hot spot, VOIP phone, and TV
--- Typical bandwidth requirement at each endpoint is 5-10 Mbps
--- For TV, amenable to a pure OTT video solution (e.g., video over TCP/IP HLS) versus multicast
--- Have proposals from several providers to use a Gigabit Ethernet solution with a star topology connected via single mode fiber (runs up to 1/4 mile or more)
--- But have also seen solutions using point-to-point radio instead of fiber at a fraction of the price of fiber proposal (e.g., Ubiquiti airFiber)
=== QUESTION ===
When/is point-to-point radio a viable alternative to fiber distribution in a case like this? What are the considerations and trade offs in terms of performance, quality of service, robustness, and long term value?
Thanks for any feedback!
