The wireless connectivity is an optional feature of Unipi Edge series. It is useful when the device needs to be connected to network in places where it is difficult or not possible to have cabled connection. All units with wireless connectivity are equipped with RP-SMA connector for external antenna. It is possible to use integrated antenna, but due to unit's aluminium chassis this option is not recommended.

/*
As standard, the Wi-Fi antenna is integrated, but an SMA connector for an external antenna can also be fitted as part of [[en:hw:004-edge#oem_features|OEM modifications]].
