Identifying Non-802.11 Interference in Hospital Wireless Design
AirPcap is designed specifically to capture 802.11 frames. It filters out all other RF energy, so it cannot detect non-Wi-Fi devices like Bluetooth or microwaves.
A Layer 1 survey uses a spectrum analyzer to see all RF energy (including non-Wi-Fi). A Layer 2 survey uses Wi-Fi adapters/APs to analyze signal strength and data rates of 802.11 networks only.
Wireless AP Placement in Historic Buildings
RF coverage depends on where APs can physically go. If aesthetics restrict mounting options, coverage design must adapt to those limits, not vice versa.
Yes, ornate coverings can cause attenuation, but the placement strategy is driven first by whether you are allowed to drill or mount visible equipment.
