Synetcom's 900 MHz Ethernet PLC Radio is a rugged, long range 900 MHz radio that connects PLC, RTU, I/O and other SCADA equipment. The radio is designed to provide high speed wireless connectivity between PLCs and PLC networks - without compromising reliability and performance. Typical uses include Ethernet bridging, SCADA device networking, PLC networking and industrial wireless data acquisition and control.

The product can function as a high speed bridge between two Ethernet networks, or it can provide wireless networking between an HMI computer + master PLC and multiple remote slave PLCs.  Complex data acquisition and control systems can be built using repeaters to extend range and coverage.

Data Throughput and Range
The 900 MHz Ethernet PLC Radio operates with data throughput significantly higher than other industrial (FHSS) Ethernet radios:

WISE-B-900: 150 KB/s (25 miles with 11 dBi gain antennas)

Maximum throughput occurs on a point-to-point link.  Error-free data transmission is assured via CRC error checking and ARQ (automatic retransmission of packets with bit errors).

Why doesn't the radio transmit at 10 MB/s?  Industrial Ethernet applications often demand long range and high reliability which is obtained only by operating the link more slowly - a limitation of physics, not the radio design.

For example, faster commodity 802.11 Ethernet bridges or routers offer a higher throughout but only over short distances (1-2 miles under ideal conditions) with the same reliability our radios deliver at 25 miles.

Comparison to 2.4 GHz                               Our 2.4 GHz Industrial Ethernet Radios typically operate at 220 KB/s or faster by design.  Actual data throughput may be compromised if there are obstructions in the radio path.  The 900 MHz Wireless Ethernet Modem is less affected by obstructions.
