Mesh: AP-to-AP Backhaul Distance Capability Capabil ity should be
W iFi Network Network Planning Involves:
2x AP-to-Client
Site Survey to Identify: AP AP Location & Height, Line-of-Sight Line -of-Sight (LoS)/Partial LoS, Interference, Access to wired wir ed backhaul (i.e. Max # Hops), …
Client type (Smart Phones, Tablets, Laptops, …) Weakest Link typically typicall y would would be the Uplink on a Smart Phone
User Experience: Minimum Throughput to User, User, Type of Applications (Internet, Video, Gaming, ….)
CAPEX & OPEX available avai lable for project; Match Match to type of Service, Robustness of Coverage, …
Regulatory Considerations; different countries countries allow all ow different Tx power at different Frequency Bands.
Type of AP Used: AP1552E&H (External ( External Ant.), AP1552C&I (Integrated Ant.)
AP1552E, AP1552H : Antenna Gain 2.4 GHz (4 dBi), 5 GHz (7 dBi)

DFS required by Regulations Regulations to allow allow WLAN to shar share e the 5GHz 5GHz band band with with Rada Radarr All Cisco products are compliant
Best Practices for Radars: Do
a Survey Surve y and contact the local local authorities to know if there are radars nearby Use
“Full Sector Mode” that prevents
MAPs to be isolate isolated d after detecting a radar Correctly mount mount the APs (spacing Correctly and antennas alignment) Remove the radar affected channels from the Controller Controller channel list
