Industry-Specific Wireless Solutions

The MDS SD4 is especially popular in the following industry applications:

Energy Sector 

  • Remote control of EID and controllers at distribution substations
  • Condition monitoring for pole-top circuit breakers and capacitor banks

Oil & Gas 

  • Remote data collection from meters and flow devices
  • Monitor and transmit wellhead pressure and tank levels collected by RTUs

Water and Wastewater

  • Monitor lift stations across multiple sites from control room
  • Communicate with remote PLCs controlling tank levels and water flow

Heavy Industrial

  • Activation of perimeter gates based on detection of vehicle
  • Monitor and control remote pumps and compressors

Primary Advantages of the MDS SD4

The MDS SD4 makes a great fit for demanding applications such as those listed above thanks to the following advantages:

Long Range Communications

The MDS SD4 offers secure, reliable, long distant transmission of data by combining 5 Watt transmit power and exceptional receiver sensitivity to support wide coverage areas. It also ensures maximum performance in difficult terrains or when obstructions such as trees and buildings limit the effectiveness of other wireless devices.

Exceptional Network Performance

The MDS SD4 is equipped with features that provide maximum performance, including Media Access Control (MAC) optimized to reduce Ethernet overhead and preserve bandwidth. It also features an IP Payload feature which removes unneeded Ethernet frames to shrink messages and improve throughput.

Backward Compatibility

MDS SD4 radios can be directly added to existing MDS x710 and x790 systems as either expansions or replacements to add Ethernet support. This preserves your investment and allows a smooth transition from other infrastructure to IP/Ethernet without disrupting day-to-day operations.
