245U-E Wireless High-Speed Ethernet Modem

Key Features:

245U-E Wireless High-Speed Ethernet Modem

The ELPRO  245U-E wireless Ethernet modem is a license free wireless transceiver designed to
Provide communications over high bandwidth and also operate in Access Point/Client configuration, functioning as a network Bridge/Router, or serving as a Serial Server. The optimized throughputs of the ELPRO  245U-E (108 Mbps) which provides durable and secure two-way wireless communications made it possible for the modem to operate in extremely challenging outdoor environments over obstructed paths such as found in monitoring and control applications.
