# Survey Hardware

To perform site surveys, Hamina Onsite needs access to site survey hardware. This can be either a [Hamina Clip](https://docs.hamina.com/hamina/onsite/hardware/clip), an [Oscium Nomad](https://docs.hamina.com/hamina/onsite/hardware/oscium-nomad), or a [WLAN Pi](https://docs.hamina.com/hamina/onsite/hardware/wlan-pi).

### 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.
