Total solutions provider of GE MDS industrial wireless data communications systems & services. * Established in 2002 * Specializing in all things relating to Wireless Data Communications MDS Triple Certified Full Service Partner for: Iowa, Minnesota, Montana, Nebraska, North Dakota, South Dakota, & Wyoming

3 A well designed, well installed, well maintained wireless system is a beautiful thing

4 Resolving the Practical Problems Associated With Advancements & Trends In Wireless Systems Technology

5 Where is wireless coming from and where is it going?

6 Well, in the beginning, things were pretty basic Analog Communications First Electron Tubes (1930s 1950s) then Transistors (1960s s)

7 But This Was The Age Of Analog Communications But Analog Waveforms Are Highly Susceptible To Noise & Distortion. So what starts out at the transmitter looking like this: Typically ends up at the receiver looking like this:

8 Digital Communications Then came digital

9 Digital Communications and the Digital Signal Processor! Which allowed radios to perform multiple tasks simultaneously: * Noise Filtering * Forward Error Correction * Over-the-air Diagnostics

10 Legacy Point-To-Multipoint RS-232 Serial Radio System 1980s Point-To-Multipoint RS-232 Serial Radio System ELECTRIC UTILITY GAS/OIL WELL WATER UTILITY MDS REMOTE PIPELINE DIAGNOSTICS COMPUTER LOTTERY / FINANCIAL MDS MASTER STATION HOST COMPUTER

11 Ethernet Communications and then came Ethernet and what started out in the office was quickly adapted to industrial communications systems.

12 Ethernet Communications and then came Networking and the ability to send any packet, to any port, on any device, anywhere - on a given network.

13 A typical utility SCADA system today * Legacy systems still in service * Newer generation/ethernet systems being installed: - Transparent Mode - Hybrid networks # Spectrum sharing # Non-spectrum sharing

14 The Evolving Wireless Landscape Growing Demand for Additional Network Connectivity More smart machines producing more data, passing over more connections. GE MDS Wireless Industrial Communications

15 The Evolving Wireless Landscape Growing Demand for Additional Network Connectivity Increased wireless network demands require optimal wireless links, sound network plans, and network equipment configurations that minimize OTA traffic.

16 The Evolving Wireless Landscape Increasingly Complex Wireless Networks that work! Multiple network segments on a single, integrated, manageable, secure network.

17 Ethernet Networking Issues What could go wrong?

18 Ethernet Networking Issues The rapid adoption of highly sophisticated wireless systems & complex industrial control Ethernet networks has resulted in expertise gaps between what is required and what is available.

19 Ethernet Networking Issues Knowledge of, and experience working with, legacy RS-232 serial connectivity radios and field devices is of little use when dealing with state-ofthe-art Ethernet based wireless networks.

20 Ethernet Networking Issues Some advanced Ethernet networking knowledge is a must. Other requirements: * Realistic expectations. * A sound network IP address scheme employing network segmentation where appropriate. * Network equipment (managed switches and/or routers) configured to shield low bandwidth wireless networks from unnecessary Ethernet traffic.

21 And, due to increased demand, manufacturing technology has advanced & add l frequency bands have been created MHz Licensed MHz Licensed MHz Licensed MHz Licensed MHz Licensed MHz Unlicensed GHz Unlicensed GHz Registered GHz Registered GHz Unlicensed GHz Unlicensed GHz Licensed But, competent use of higher frequency radio systems requires more than just basic knowledge of electromagnetics, antenna theory, and transmission lines.

42 To Do List: Commit to planning for (and riding ) the waves of change. Take advantage of highly beneficial new technology. Understand the limits of limited wireless system expertise. Ensure that both the design & installation of sensitive systems are performed by those with proven expertise. Plan for funding & facilitating additional staff training. Seek out and work only with ITS support, and product vendors known to have invested in advanced wireless systems and network training for their staffs.

43 The path to an optimally designed, optimally functioning, optimally maintained wireless system can be difficult But with the right technology partners the ride can be a smooth one!
