6.5.3 WLAN filters
In addition to encryption (see 6.5.1 Access point),
you can secure your wireless network even more by us-
ing a Wi-Fi filter to limit access to Wi-Fi devices. Even
if the encryption is switched off, the device will not es-
tablish a connection.
The Wi-Fi filter should be used only
as an additional option. By using it
you could limit access to your wire-
less network, but without encryption it would be relatively easy for third parties to
eavesdrop on all of your data transmissions.
