recommendation for CleanAir remains the same as normal Mesh AP
Deployment (800/1000 feet cell radius) APs should be RF neighbors
for any possibility of Merging (spatial proximity) Location
Resolution in the Outdoors is to the nearest AP Devices generally
are located near the AP which is physically closest to the device
Outdoor Custom Calibration possible from 7.0.116.0 onwards Location
error may double without custom calibration model Installation with
a low density of sensors has the possibility of having duplicate
entries of interferes Mixing CleanAir (AP1552) and Legacy APs

58. Design & PlanningGeneral Considerations RF Nature: Not
an Exact Science, Especially in Unlicensed Spectrum Mesh: AP-to-AP
Backhaul Distance Capability should be 2x AP-to-Client WiFi Network
Planning Involves: Site Survey to Identify: AP Location &
Height, Line-of-Sight (LoS)/Partial LoS, Interference, Access to
wired backhaul (i.e. Max # Hops), Client type (Smart Phones,
Tablets, Laptops, ) Weakest Link typically would be the Uplink on a
Smart Phone User Experience: Minimum Throughput to User, Type of
Applications (Internet, Video, Gaming, .) CAPEX & OPEX
available for project; Match to type of Service, Robustness of
Coverage, Regulatory Considerations; different countries allow
different Tx power at different Frequency Bands. Type of AP Used:
AP1552E&H (External Ant.), AP1552C&I (Integrated Ant.)
AP1552E, AP1552H : Antenna Gain 2.4 GHz (4 dBi), 5 GHz (7 dBi)
AP1552C, AP1552I: Antenna Gain 2.4 GHz (2 dBi), 5 GHz (4 dBi)
