AP on a Stick (APoS)
An “AP on a stick” Wi-Fi survey is a type of on-site survey used to assess and optimise the coverage and performance of a Wi-Fi network. In this survey method, a temporary access point (AP) is placed on a pole or stand at specific locations within the area of interest.
The “AP on a stick” survey is particularly useful in complex environments, where the Wi-Fi signal behaviour is affected by factors like building materials, obstructions, and other RF interference sources. By simulating the actual Wi-Fi network conditions using a temporary AP, the surveyor can gather accurate and reliable data to fine-tune the network design for optimal performance.
This type of survey is typically conducted during the deployment phase of a Wi-Fi network to ensure that the access points are strategically placed, and the network is configured to deliver reliable and consistent wireless connectivity to users.
The process typically involves the following steps:
– Access Point Setup: The surveyor configures a portable AP with the same specifications as the planned production access points. This includes setting the same SSID, security settings, and channel assignments.
– AP Placement: The surveyor physically places the temporary AP at different locations throughout the area, typically at the height and position where the production access points will be installed.
– Signal Measurement: With the AP in place, the surveyor uses specialized Wi-Fi survey software or tools to measure and record the signal strength and quality at various points within the coverage area.
– Walkthrough: The surveyor walks through the space while carrying the survey tool to collect data in different areas, both indoors and outdoors, including areas where signal coverage is crucial.
– Data Analysis: After collecting the data, the surveyor analyses the signal measurements to identify areas with weak signal strength, potential interference, and coverage gaps.
– Network Optimisation: Based on the data analysis, adjustments are made to the AP placement, transmit power, and channel settings to optimise coverage and minimise potential sources of interference.
– Report Generation: A comprehensive report is generated, including heatmaps and signal strength visualisations. The report provides insights into the Wi-Fi network’s performance, coverage, and potential areas that may require further optimisation.
