In contrast, when increased link robustness and noise immunity is desired, MIMO can be used in a 1
stream configuration. In this scenario, the same information is carried across both RF chains,
increasing the reliability of reception.
It is recommended that both Base Station and Client Unit share the same Modulation and Stream
settings.
9. Security
Navigate to
Configuration -> Security
to access the Security Configuration screen. Base Station
screen shown here:
Three security options are available: Open, AES and Radius. All units on a wireless network must
share the same security settings.
Open:
Removes all encryption and formal authentication methods. Note that even with the “Open”
setting, there is still a MAC address based Access Control system which provides a basic level of
security. (See the section on Access Control)
AES:
Provides 128-bit AES data encryption with passphrase/shared-key based authentication.
Radius:
This option combines AES data encryption with Radius/802.1x authentication capability,
compatible with MS-CHAPv2/EAP authentication servers.
Notes
:
(a) AES passphrase and Radius identity / secret / password fields are case sensitive with no spaces
allowed. Passphrase must be between 8 and 63 characters in length. The shared-key must be 64
Hex digits.
(b) Radius identity must contain an ‘@’ symbol, and is typically in email address format.
(c) Legal characters are: all alphanumerics, plus the following symbols:
@ (at sign) - (dash) . (period) ‘ (tick) _ (underscore)
