1. What is acceptable downtime on pure 60GHz. It is possible to engineering it to practically no downtime although less economical. Zero. If it goes down the phone will ring. With a well designed and installed Canopy system there was no downtime.
2. What is the acceptable backup bandwidth? If there is at least SOME internet available during 4-5" rains, is that acceptable? If you are talking about something built in, then the acceptable backup is whatever fools the customer into thinking that Netflix is not impacted.
