Ricoh Interface Unit M19 Wireless Firewall

The Ricoh Interface Unit M19 is a new firewall and network security device that supports IEEE 802.11a/g/n wireless connectivity. It is designed for environments that require integrated wireless access alongside security functions. The unit carries the manufacturer part number R-CMN-851-A and was first listed in 2022.

Suited for Legacy Wireless Security Deployments

This appliance suits administrators maintaining networks built around 802.11a/g/n infrastructure who need a dedicated security gateway. It is not for buyers who require wireless standards beyond those listed, nor for installations that demand wired-only firewall appliances without integrated radio hardware.

IEEE 802.11a/g/n Wireless Support

The single specification that determines suitability is the supported wireless standard set: IEEE 802.11a/g/n. If the target network operates exclusively on these protocols, the unit matches the requirement; otherwise a different device must be selected.
