Duo 5 is a 5GHz wireless Ethernet bridge using the MRTP technology designed exclusively for systems with separate radios for data transmission and reception. Duo 5 is capable of transmission with much higher speeds than devices using carrier multiple access (CSMA/CA, TDMA, polling), ie. IEEE 802.11 (WiFi), especially on very long-range connections. Duo 5 is based on two radio modules working in 5GHz band and on a dual polarized antenna. The device is enclosed in a compact, weatherproof enclosure with a simple mounting system. Performance effective TCP/IP bandwidth for 20MHz-wide channel: 50Mbps in each direction simultaneously range: up to 15 km packet performance: over 60 000 pps Features innovative radio transmission protocol: MRTP no bandwidth degradation with distance increase radio bandwidth is the bandwidth available "on interface" concurrent frame fragmentation and aggregation asynchronous retransmission automatic selection of modulation, frame size and transmit power modes of minimal latency and strict ordering of Ethernet frames AES-CCMP encryption with automatic key negotiation operation in IEEE 802.3 (Ethernet) bridge mode STP protocol support (IEEE 802.1D) fully transparent, especially to VLAN traffic (IEEE 802.1Q) Ethernet frame filter support for ARP, DHCP, SMB and PPPoE protocols support for destination MAC address translation (MAC DNAT) QoS support simple usage and installation PoE (Power over Ethernet) support (IEEE 802.3af) automatic antenna polarization selection automatic radio parameters selection small dimensions and low weight advanced, multilingual web interface interactive, real-time graphical statistics of the device multilingual, simple command line interface accessible via SSH protocol SNMP diagnosis device warranty: 24 months price for one unit Reset to default procedure
