Antennas 2 external R-SMA antenna connectors per radio module; vertical/horizontal
polarity incl. antenna diversity, scope of delivery: 2 x 5 dBi Omni (2.4 GHz) +
2 x 7 dBi Omni 5 GHz (with RAP/RAC1000 series only)
Operational mode Client, access point or monitor mode can be configured
SSID Network name may include up to 32 characters incl. special characters
Long distances Distance setup option for long distances to facilitate automatic adjustment
of SIFS and ACK timeout values
Antenna diversity Antennas are selectable for setups including one antenna, or can automatically
be selected for the best antenna with respect to transmission and reception
Transmission power Transmission power can be configured between 0 dBm and 30dBm
WLAN security
Security modes WEP64, WEP128, WPA/TKIP, WPA2/CCMP (AES)
WPA authentication WPA-PSK WPA radius (enterprise), 802.1x:
Access Point primary and secondary radius server
Access Client phase 1: EAP/TLS, EAP/PEAP, EAP/TTLS
phase 2: MD5, MSCHAPv2
Other WPAs GMK and PMK rekeying interval can be configured, WP parameters
Static MAC filter MAC filter in access point mode, up to 500 MAC addresses can be configured,
fast import by using the text-file upload function
Hide SSID Yes
X.509 certificate administration – Separate certificate administration for verification
– Upload function for client, CA and CRL certificates
– Preinstalled demo certificate set to facilitate quick functional tests
IAPP The Inter Access Point Protocol ensures that all access points list a certain
client just once in their internal association tables. It ensures that the MAC
address tables of the switch are automatically updated immediately, even if
the client doesn’t send any data at all. ads-tec IAPP extension: IAPP client
update, for auto-channel function with roaming table.
Roaming
Optimum roaming characteristics thanks to four different methods:
– Standard roaming: Optimised for speed thanks to restricted channel lists,
roaming thresholds and the option to configure active scanning
– Roaming tables: A permanent order of access points can be configured,
e.g. with linear vehicle systems (incl. Modbus/TCP API for direct control of
characteristics)
– Seamless roaming: Roaming without any interruptions – only in connec
-
tion with ads-tec Access Points and Access Clients
– Extended background scanning: Background scanning using 2 WLAN
adapters, allows fast roaming with high packet-rate data traffic
(only with RAC1x2x)
