Service Areas. The hidden networks shall not actively transmit beacons nor respond to
requests with partial information only. Due to this the various scans - including the initial scan -
in 7signal Sapphire do not capture hidden networks. Tests related to traffic analysis shall

typical analysis tool shall find hidden network as soon as there are any payload
