4. MDS SD4 – Market Demands
Increased demand for Ethernet and TCP/IP technology to facilitate the operation and maintenance of SCADA systems
Users of radio communications in Utility SCADA are concerned with an increasing “noise floor” and the potential for radio interference in the unlicensed bands (ISM Band WiLAN)
Regulatory changes require radio communications with greater spectral efficiency and increased cyber security
GE MDS has sold licensed band radios since the first model came out in We have the most expertise in design of this type of radios.
In last 2-3 years there has been a growing concern with interference in the unlicensed band. And a concern with security in general, and specifically with wireless. The concerns with reliability and cost of installing and operating a communications system are also applicable, although they are not new.
Tremendous pressure to do more with less personnel. Opportunity for more automation. 25% of the workforce expected to retire in the next 5 years, 50% to retire in 10 years. TCP/IP technology is an enabler of greater control with less effort and much simpler operation and maintenance of communication systems in general, and wireless systems in particular.
Critical infrastructure organizations with Private Land Mobile Radio (PLMR) frequencies between 150 MHz and 512 MHz are mandated by the FCC to narrowband in order to improve overall spectrum efficiency. We've heard that many customers are taking this opportunity to analyze their entire communications network in order to build a next-generation system that will allow for their needs today and in the future.

25. SD4 and IP/Ethernet Data
All IP connections terminate locally at the SD radio
The transmitting SD extracts RTU data packet content and broadcasts it over-the-air
The receiving SD regenerates the TCP/UDP data packet
Makes efficient use of the channel, but has limitations
SD radios don’t route or bridge Ethernet data, it encapsulates industrial protocols in IP payloads
