Lancom OAP-321-3G Brochure & Specs - Lancom Oap-321-3G
LANCOM OAP-321-3G
Scope of features: as of LCOS version 8.5x
IEEE 802.11n Features
MIMO
MIMO technology is a technique which uses multiple transmitters to deliver multiple data streams via different spatial channels.
LANCOM uses a 3 x 3 MIMO Configuration where 2 data streams are spread over 3 transmitters. Depending on the existing RF
conditions the throughput is doubled with MIMO technology
40 MHz Channels
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.
MAC Aggregation and Block
Acknowledgement
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%.
Short Guard Interval
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%
BFWA*
Support for Broadband Fixed Wireless Access in 5.8 GHz band with up to 4 Watt EIRP for WLAN point- to- point links according
to the national regulations of your country, special antennas required
*) Note
The use of BFWA is subject to country specific regulation
WLAN operating modes
WLAN access point
Infrastructure mode (autonomous operation or managed by LANCOM WLAN Controller)
WLAN bridge
Point- to- multipoint connection of up to 7 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
WLAN router
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
WLAN client
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
UMTS modem
Supported standards
UMTS, HSPA+ (HSPA+ with up to 21 Mbps, HSUPA with up to 5.76 Mbps), Edge, and GPRS support
UMTS and HSxPA bands
850/900/1900/2100 MHz
EDGE/GPRS bands
850/900/1800/1900 Mhz (EDGE up to max. 236kbps)
Diversity support
Receive diversity on the aux antenna
Firewall
Stateful inspection firewall
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)
Packet filter
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
Extended port forwarding
Network Address Translation (NAT) based on protocol and WAN address, i.e. to make internal webservers accessible from WAN
N:N IP address mapping
N:N IP address mapping for translation of IP addresses or entire networks
Tagging
The firewall marks packets with routing tags, e.g. for policy- based routing
Actions
Forward, drop, reject, block sender address, close destination port, disconnect
Notification
Via e- mail, SYSLOG or SNMP trap
Quality of Service
Traffic shaping
Dynamic bandwidth management with IP traffic shaping
Bandwidth reservation
Dynamic reservation of minimum and maximum bandwidths, totally or connection based, separate settings for send and receive
directions. Setting relative bandwidth limits for QoS in percent. Bandwidth control and QoS also for UMTS connections
DiffServ/TOS
Priority queuing of packets based on DiffServ/TOS fields
Packet- size control
Automatic packet- size control by fragmentation or Path Maximum Transmission Unit (PMTU) adjustment
Layer 2/Layer 3 tagging
Automatic or fixed translation of layer- 2 priority information (802.11p- marked Ethernet frames) to layer- 3 DiffServ attributes in
routing mode. Translation from layer 3 to layer 2 with automatic recognition of 802.1p- support in the destination device
Security
Intrusion Prevention
Monitoring and blocking of login attempts and port scans
IP spoofing
Source IP address check on all interfaces: only IP addresses belonging to the defined IP networks are allowed
Access control lists
Filtering of IP or MAC addresses and preset protocols for configuration access
Denial of Service protection
Protection from fragmentation errors and SYN flooding
General
Detailed settings for handling reassembly, PING, stealth mode and AUTH port
