LANCOM
Scope of features: as of LCOS version 7.5x
| WLAN |
|
|
| Radio channels 2.4 GHz | Up to 13 channels, max. 3 |

|
|
| Radio channels 5 GHz | Up to 19 |
|
|
|
|
|
| Roaming | Seamless handover between radio cells, IAPP support, IEEE 802.11d support |
|
|
|
|
|
| 802.11i fast roaming |
| |
|
|
|
|
| Fast client roaming | With background scanning, moving LANCOM "client mode" access points |
|
|
| offer a better signal before Roaming |
|
|
|
|
|
| VLAN | VLAN ID definable per interface, WLAN SSID, |
|
|
|
|
|
| Dynamic VLAN assignment | Dynamic VLAN assignment for target user groups based on MAC addresses, BSSID or SSID by means of external RADIUS server. |
|
|
|
|
|
| Support of layered 802.1q VLANs |
| |
|
|
|
|
| Simultaneous use of up to 8 independent WLAN networks per WLAN interface |
| |
|
|
|
|
| Security | IEEE 802.11i / WPA2 with passphrase or 802.1x and |
|
|
| user authentication, 802.1x /EAP |
|
| RADIUS server | Integrated RADIUS server for MAC address list management |
|
|
|
|
|
| EAP server | Integrated EAP server for authentication of 802.1x clients via |
|
|
|
|
|
| Quality of Service | Prioritization according to Wireless Multimedia Extensions (WME, subset of IEEE 802.11e) |
|
|
|
|
|
| Bandwidth limitation | Each WLAN client (MAC address) can be assigned maximum transmit and receive rates and to an individual VLAN ID |
|
|
|
|
|
| Background scanning | Detection of rogue AP's and the channel information for all WLAN channels during normal AP operation. |
|
|
| The Background Scan Time Interval defines the time slots in which an AP or Router searches for a foreign WLAN network in its |
|
|
| vicinity. The time interval can be specified in either milliseconds, seconds, minutes, hours or days. |
|
|
|
|
|
| Client detection | Rogue WLAN client detection based on probe requests |
|
|
|
|
|
| 802.1x supplicant | Authentication of an access point in WLAN client mode at another access point via 802.1X |
|
|
|
|
|
| Note | * The effective distance and transmission rate that can be achieved are depending of the site RF conditions. |
|
|
|
|
|
