ProSoft Technology’s RadioLinx® wireless product family has been expanded to include a 802.11abg Industrial Hotspot™ with IP66-rated water resistant, dust-proof enclosure (RLX-IHW-66). This radio functions as an access point, repeater, or client and its water resistant enclosure permits it to be directly installed in areas which are exposed to harsh industrial or environmental conditions.

From the press release:

“The RLX-IHW-66 is equipped with RF-based Internet Group Management Protocol (IGMP) Snooping, a tool which allows multicast filtering at the wireless level, so that the radio transmitting data from the producer (such as a distributed I/O block) is able to identify the consumer (i.e. a PLC) and transmit the producer data directly to the consumer as opposed to multicasting the information to the entire wireless network. Since the RLX-IHW-66 sends the data directly to each of the consumers, it’s able to confirm receipt of the data and retransmit the data if necessary. RF-based IGMP prevents crowding over the air by only sending messages only where they need to go and it increases reliability by confirming receipt of the data.”
