Maximize AP Placement
Updated over a week ago

To ensure the best outcome of your wireless technology solutions, make sure to adhere to the following: - Place the AP as close to client devices as possible. Avoid hotel hallways. Minimize obstructions between APs and clients as well. Most guests in your hotel need to have their devices in physical sight of the AP to get the best Wi-Fi connection (e.g. in room APs). - Make sure the hotel APs are staggered them horizontally and vertically. Do not stack them floor to floor due to interference for your guests and hotel staff members. - Space out APs evenly. This allows for static and uniform transmit power settings. It also simplifies the channelization process. - Use the hotel’s building structure (e.g., walls and corners) to isolate neighboring APs. Avoid mounting behind obstructions, or above ceilings and near ducts and pipes. - Place neighboring APs to not be in line of sight (LoS) of each other. If they are too close, they will have overlapping coverage areas and greater interference, especially in hotel hallways. Make sure neighboring APs are on independent/non-overlapping channels. - Only use 20 MHz channels at 2.4 GHz. 802.11n allows for 40 MHz channels, but never use these in any multi-AP deployment. You can’t have two 40 MHz channels that are independent. Instead, ONLY use 20 MHz in 2.4 GHz.

Only use the three independent 20 MHz channels in 2.4 GHz (802.11.b/g/n): 1, 6, and 11. (Each channel is only 5 MHz separated from its neighbor.) - Avoid DFS (Dynamic Frequency Selection) channels for indoor deployments. Use DFS channels for point-to-(multi) point links. - Start with 20 MHz channels at 5 GHz; scale up to 40 MHz if needed. - Use static independent channels in an alternating pattern on both 2.4 GHz and 5 GHz. - Ensure your SSIDs are different on each band if you’re not using band steering. Most environments use “Prefer 5 GHz” with a -80 dBm threshold. - Validate the 5 GHz capabilities and limitations of known client devices, and plan your channels accordingly. - Use static transmit power settings with at least 6 dBm on 2.4 GHz and “medium” on 5 GHz in AP Group Settings.
