# Survey Hardware To perform site surveys, Hamina Onsite needs access to site survey hardware. This can be either a [Hamina Clip](/hamina/onsite/hardware/clip.md), an [Oscium Nomad](/hamina/onsite/hardware/oscium-nomad.md), or a [WLAN Pi](/hamina/onsite/hardware/wlan-pi.md). ### MacBook Wi-Fi Adapter Surveys Additionally, it is possible to use Hamina Onsite for macOS without external survey hardware; a MacBook Wi-Fi adapter can be used for measurements, directly. The downside is that one adapter takes a very long time to sweep through all of the Wi-Fi channels, so measurements take considerably longer and are spaced further apart while walking. Because of this, we only recommend surveying with a MacBook Wi-Fi adapter when absolutely necessary. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.hamina.com/hamina/onsite/hardware.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
