Synetcom's PLC Ethernet Radio is a rugged, field-proven long range 2.4 GHz 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 PLC Ethernet Radio operates with data throughput significantly higher than other industrial (FHSS) Ethernet radios:

WISE-B: 220 KB/s (35 miles with 24 dBi gain antennas)

WISE-BF: 500 KB/s (15 miles with 24 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 35 miles.

Comparison to 900 MHz                             900 MHz industrial Ethernet modems typically operate at <150 KB/s by design, since less bandwidth is available in the 900 MHz band.  Actual data throughput is often compromised further by interference from other users, even if sophisticated hopping algorithms are used in the 900 MHz radio. 

Directional antennas (Yagi or Dish) are required for long distance links at either 900 or 2.4 GHz.  2.4 GHz antennas have higher gain and narrower beamwidths, favoring the desired signal, while rejecting interference from other directions more effectively than 900 MHz antennas.
