Wireless Ethernet and Serial Ports

When the UHF band is needed for terrain coverage, ESTeem Model 195C wireless radios are the perfect solution for rigorous Industrial, Public Safety, and Federal applications. Providing Ethernet, Serial RS-232C, RS-422, RS485 and 4 Channel Sensor Interfaces in a single wireless unit, the Model 195C industrial modem is a narrowband compliant licensed radio with downward compatibility to the ESTeem Model 192C/CHP series.

The 195C operates well in a wide range of modes, including point to point wireless bridge, point to multipoint and repeater modes.

Depending on the type of antenna chosen, these Ethernet/serial radios provide reliable communications over distances greater than 10 miles in high noise. Wireless networks over large geographical areas can be a reality using the internal Digi-Repeating feature, which creates possible repeater sites using any remote locations.
