The network signal for a single wireless access point might be limited by its coverage range.
Therefore, if you want to expand the wireless network in a large exhibition with a quick
method, you can install multiple access points with enabling the Roaming feature for each
AP to reach the purpose of expanding wireless signals seamlessly.
These access points connecting for each other shall be verified by pre-authentication. This
page allows you to enable the roaming feature and the pre-authentication.
Available settings are explained as follows:
Item Description
PMK Cache Period

SSID with which it has pre-authenticated. Such feature is
available for
WPA2/802.1
mode.
Pre-Authentication
Enables a station to authenticate to multiple APs for roaming
securer and faster. With the pre-authentication procedure defined
in IEEE 802.11i specification, the pre-four-way-handshake can
reduce handoff delay perceivable by a mobile node. It makes
roaming faster and more secure. (Only valid in WPA2)
