 Adaptive Coding Modulation (ACM): QPSK to 64 QAM
 Half duplex or full duplex RF operation
 Ethernet data interface and RS-232 / RS-485 asynchronous multiple port options
 Software selectable dual / single antenna port options (dual antenna port for external duplexers or
filters)
 Data encryption and authentication using 128,192 and 256 bit AES and CCM security standards
 Terminal server operation for transporting RS-232 / RS-485 traffic over IP or Ethernet
 Mirrored Bits ® support for RS-232
 IEEE 802.1Q VLAN support with single and double VLAN tagged and add/remove VLAN manipulation
to adapt to the appropriate RTU / PLCs
 QoS supports using IEEE 802.1p VLAN priority bits to prioritize and handle the VLAN / traffic types
 QoS per port (Ethernet, serial, management)
 L2/3/4 filtering for security and avoiding narrow band radio network overload
 L3 Gateway Router mode with standard static IP route for simple routing network integration
 L3 Router mode with per Ethernet interface IP address and subnet
 L2 Bridge mode with VLAN aware for standard Industrial LAN integration
 Ethernet header and IP/TCP / UDP ROHC header compression to increase the narrow band radio
capacity
 Ethernet and serial payload compression to increase the narrow band radio capacity
 Pseudo peer to peer communication between remote stations through base-repeater or repeater
stations
 SuperVisor web management support for element and sub-network (base-repeater-remotes)
management
 SNMPv1/2/3 & encryption MIB supports for 4RF SNMP manager or third party SNMP agent network
management
 SNMP context addressing for compressed SNMP access to remote stations
 SNTP for accurate wide radio network time and date
 RADIUS security for remote user authorization, authentication and accounting
 Build-configuration / flexibility of serial and Ethernet interface ports (3+1, 2+2, 4+0)
