Can someone provide me with the mean time before failure (MTBF) for the IAP-115, IAP-225? In what documentation would I find an installation height to signal propagation table, chart, or ratio for the IAP-115 and IAP-225? For an IAP cluster, I understand that all management traffic is forwarded to the virtual controller and then to Airwave. For standard traffic (i.e. browsing) is that traffic first forwarded to the virtual controller then put on the LAN or is that traffic forwarded straight from the IAP to the LAN?
