The 195Ed is a spread spectrum modem with integral Ethernet and Serial ports operating in the 902 to 928 MHz unlicensed frequency band with RF data rates from 1 to 54 Mbps. With a range of up to 20+ miles, 195Ed provides users with the speed and bandwidth of IEEE 802.11b/g/a products without the security concerns or co-channel interference from nearby deployed consumer hardware. The lower propagation losses in the 900 MHz spectrum give significant range advantages over radios in higher frequency bands within a given environment.
195Ed’s industrial NEMA 4 case for outdoor pole mounting allows users to bridge Ethernet point to multi-point computer and/or PLC networks. The “Self-Healing MESH” feature permits redundant wireless networks to be deployed over large geographical areas by allowing any radio to act as a “repeater”, routing data through any other radio site within communication range. This feature also builds robust sites by allowing the radios to automatically reroute the communication path if a failure in the primary path occurs. The “Station” mode allows the 195Ed to function as a Roaming Client under an RF MESH network.
195Ed will give users bandwidth for SCADA, VoIP, Video and DF1 protocol needs including wireless Remote I/O control applications (Implicit Messaging). The RS-232 serial capability will allow the ESTeem 195Ed even greater flexibility of input devices and applications already served by the Ethernet based wireless modems.
All the ESTeem products and features will be shown at Booth 417. The 195Ed and 195Ep will also be on display in the Rockwell Automation Ethernet/IP booth. Electronic Systems Technology, a publicly held Corporation since 1984, was the first company to develop the wireless modem and receive the United States and Canadian patents for this technology.
