The ADSL2+ WLAN router LANCOM 1821+ Wireless ADSL offers maximum flexibility for secure VPN interconnection of sites, branch offices or home offices. Professionally secured and expandable VPN connections are its most basic functions. Offering convenient control and management of certificates, innovative routing functions which, for example, can completely separate private and business data traffic, as well as central management at no cost, LANCOM routers give administrators maximum efficiency in installation and management. Meeting with the demands of modern office environments, the router supports the very latest WLAN security standards. The USB host port enables a connected printer to be operated centrally. LANCOM Voice over IP options round out the solution with all of the IP telephony functions that users need in everyday business. In combination with the Voice-over- IP telephone LANCOM VP-100 and the Ethernet switch LANCOM ES-1108P, the LANCOM 1821+ Wireless ADSL is a future- ready, integrated all- round solution for the home office.
More flexibility.
The integrated wireless module makes the LANCOM 1821+ Wireless ADSL also suitable for use as an access point or WLAN bridge. The support of WLAN standards IEEE 802.11a/b/g/h/i and the two dualband diversity antennas enable operation in the 2.4 or 5 GHz frequency bands. In both frequency bands, the turbo mode supports maximum data transfer rates of up to 108 Mbps.
More Security.
The integrated firewall with the latest security functions such as stateful inspection, Intrusion Detection and Denial-of- Service protection is supplemented by dynamic bandwidth management and comprehensive functions for backup, high-availability and redundancy. The integrated VPN gateway that fulfills the IPSec standard, and the optional hardware accelerator provide optimal security for connecting telecommuters and branch offices thanks to the high- security 3-DES or AES encryption and support of digital certificates.
LANCOM is setting the standards in area of WLAN security, too. A comprehensive range of security technologies is supported in wireless LAN including IEEE 802.11i, 802.1x, WPA, WEP64/128/152, ACL or LEPS (LANCOM Enhanced Passphrase Security), which enables the configuration of an optimized solution, whatever the individual requirements. For example, Multi SSID allows the definition of up to 8 user groups, each with its own level of security.
More Management.
The management systems LANconfig and LANmonitor are included and offer not only cost- effective remote maintenance of entire installations and highly convenient setup wizards, but also full real-time monitoring and logging. What’s more, service providers benefit from the broad range of scripting methods and professional access with individual access rights for administrators via SSH, HTTPS, TFTP and ISDN dial- in. WLANmonitor visualizes the structures of the WLAN irrespective of physical location and facilitates the central surveillance of the entire wireless network.
More Benefits.
The versatile functions for address translation and routing allow completely different networks to be connected over common infrastructure. Existing networks at partner companies, home-office workstations or subsidiaries can be integrated into the VPN without problem. With the option of port separation and a separate address range, your own web servers can be securely separated from the LAN. Optional SIP proxy and SIP gateway functions offer big savings through the use of existing data connections for voice transmission (VoIP telephony). The integrated ISDN interface allows remote field installations, dial-up access and CAPI featured functions such as fax services for all connected PCs.
More Certainty for the Future.
From the very start, LANCOM products are designed for a product life of several years. They are equipped with hardware dimensioned for the future. Even reaching back to older product generations, updates to the LANCOM Operating System—LCOS—are available several times a year, free of charge and offering major features. LANCOM offers unbeatable protection of your investment!
What’s more...
LANCOM Systems also offers suitable AirLancer client adapters—as USB, PC card and PCI versions—as well as AirLancer Extender antennas for indoor and outdoor use, even in the 5-GHz frequency range.
