Extension of power saving according to IEEE 802.11e by Unscheduled Automatic Power Save Delivery (equivalent to WMM Power Save). U-APSD
supports the automatic switch of clients to a doze mode. Increasmed battery lifetime for telephone calls over VoWLAN (Voice over WLAN)
Maximum transmit and receive rates and an individual VLAN ID can be assigned to each WLAN client (MAC address)
If the link of a chosen LAN interface breaks down, a WLAN module can be deactivated to let the associated clients search for a new base station
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
Rogue WLAN client detection based on probe requests
Authentication of an access point in WLAN client mode at another access point via 802.1X (EAP-TLS, EAP-TTLS and PEAP)
Layer-3 Tunneling in conformity with the CAPWAP standard allows the bridging of WLANs per SSID to a separate IP subnet. Layer-2 packets are
encapsulated in Layer-3 tunnels and transported to a LANCOM WLAN controller. By doing this the access point is independent of the present
infrastructure of the network. Possible applications are roaming without changing the IP address and compounding SSIDs without using VLANs.
The WLAN standard IEEE 802.11u (Hotspot 2.0) allows for a seamless transition from the cellular network into WLAN hotspots. Authentication
methods using SIM card information, certificates or username and password, enable an automatic, encrypted login to WLAN hotspots - without
the need to manually enter login credentials.
The effective distances and transmission rates that can be achieved are depending of the site RF conditions
MIMO technology is a technique which uses multiple transmitters to deliver multiple data streams via different spatial channels. Depending on the
existing RF conditions the throughput is multiplied with MIMO technology.
Two adjacent 20 MHz channels are combined to create a single 40 MHz channel. Depending on the existing RF Conditions channel bonding doubles
the throughput.
Support of coexisting accesspoints with 20 and 40MHz channels in 2.4GHz band.
MAC Aggregation increase the 802.11 MAC efficiency by combining MAC data frames and sending it out with a single header. The receiver
acknowledges the combined MAC frame with a Block Acknowledgement. Depending on existing RF conditions, this technique improves throughput
by up to 20%.
Maximal Ratio Combining (MRC) enables the receiver (access point), in combination with multiple antennas, to optimally combine MIMO signals
to improve the client reception at long-range.
The guard interval is the time between OFDM symbols in the air. 802.11n gives the option for a shorter 400 nsec guard interval compared to the
legacy 800 nsec guard interval. Under ideal RF conditions this increases the throughput by upto 10%
Support for Broadband Fixed Wireless Access in 5.8 GHz band with up to 4 Watts EIRP for WLAN point-to-point links according to the national
regulations of your country, special antennas required
The use of BFWA is subject to country specific regulation
Infrastructure mode (autonomous operation or managed by LANCOM WLAN Controller)
Point-to-multipoint connection of up to 16 Ethernet LANs (mixed operation optional), broken link detection, blind mode, supports VLAN When
configuring Pt-to-Pt links, pre-configured names can be used as an alternative to MAC Adresses for creating a link. Rapid spanning-tree protocol
to support redundant routes in Ethernet networks
Use of the LAN connector for simultaneous DSL over LAN, IP router, NAT/Reverse NAT (IP masquerading) DHCP server, DHCP client, DHCP relay
server, DNS server, PPPoE client (incl.Multi-PPPoE), PPTP client and server, NetBIOS proxy, DynDNS client, NTP, port mapping, policy-based routing
based on routing tags, tagging based on firewall rules, dynamic routing with RIPv2, VRRP
Transparent WLAN client mode for wireless Ethernet extensions, e.g. connecting PCs or printers by Ethernet; up to 64 MAC addresses. Automatic
selection of a WLAN profile (max. 8) with individual access parameters depending on signal strength or priority
Incoming/Outgoing Traffic inspection based on connection information. Trigger for firewall rules depending on backup status, e.g. simplified rule
sets for low-bandwidth backup lines. Limitation of the number of sessions per remote site (ID)
Check based on the header information of an IP packet (IP or MAC source/destination addresses; source/destination ports, DiffServ attribute);
remote-site dependant, direction dependant, bandwidth dependant
Network Address Translation (NAT) based on protocol and WAN address, i.e. to make internal webservers accessible from WAN
N:N IP address mapping for translation of IP addresses or entire networks
