MDS SD4 OVERVIEW

The MDS SD4 is the next generation of licensed narrowband radios in 400 MHz. With a software-defined modem and an optimized hardware platform, this radio is the ideal platform for current and future deployments of SCADA and telemetry systems that monitor and control oil and gas wells, compressor stations, pipelines, fluid storage tanks, pole top transformers, circuit reclosers, capacitor banks and many others.

WHY CONSIDER A MDS SD4?

Reliable. With hardened industrial specs like a wider temperature range of operation, the MDS SD4TM meets the stringent environmental requirements for mission-critical applications, as well as the approvals that support it. This product is available for use in Class I, Division 2, Groups A, B, C & D hazardous locations.**

Lower Cost of Ownership. Integrated serial and Ethernet* interfaces provide a path for future equipment connectivity needs. Lower power consumption reduces the size of batteries and solar panels. Extended range supports lower overall infrastructure costs. The wide frequency plan reduces the number of spares required to support a system. Remote management software simplifies maintenance tasks and reduces the cost of managing the network infrastructure, and provides a non-intrusive means of maintenance and link monitoring.

Simplified Deployment & Operation. The MDS SD4TM is configured as a master station or remote radio. It can operate as a half-duplex or simplex radio. Duplex frequency split is configurable via software, providing a more flexible radio that can be used in different scenarios. Remote network management and diagnostics are available.

More Convenient. Multiple interfaces accommodate different connectivity needs with the same unit without the need of external equipment. 400 MHz operation with FCC and ETSI approvals ensure applicability around the world. Software defined operation minmizes administration and maintenance costs.
