1 Gas Well Deliquification Workshop Sheraton Hotel, Denver, Colorado February 27 March 2, 2011 What s in your Radio Communication Tackle Box? Dan Steele FreeWave Technologies

2 Definition of Tackle Box: Tackle: Equipment used in a sport or occupation, especially in fishing gear. Box: to confine or as in a box usually rectangular shaped. Consists of lures, artificial flies, fish hooks, bait, leader line, sinkers, floats/bobbers, fishing line, various tools to remove fish hooks and probably a fishing knife

3 Radio Communication Tackle Box: Consists of watt meters, spectrum analyzers, radios, antennas, coaxial cable, jumpers, lightning protection, grounding, path studies, diagnostic tools, power supplies, radio masts and towers, knowledge of radio types and SS and licensed frequencies and Serial and/or Ethernet devices.

4 Let s go Fishing! Preparation and knowledge is essential! Short & long term plans/goals. Who s the master/administrator and does he/she know what is expected? Who s going to do the work? What is the time table?

5 Let s do some planning before we go! Do you have a radio path study? Do you have a network design and list of end devices and connection types? Will there be I/O devices either local or using Modbus protocol? Are you looking at hybrid networks using Ethernet and serial radios? Security cameras? Encryption?

6 Computer Generated Path Study Bad Path Line of Sight is mandatory to enable robust reliable communications Good Path Multipath Reflectance Path Loss Software Measures Fade Margin

7 Omni & Yagi antennas - What s the difference? Think of Omni antennas in more or less round terms, with 0 db gain omnis being spherical and gain omnis becoming more and more like flattened donuts as the gain increases. When you put a donut on the table and squish straight down, the round shape remains as viewed from the top, but the width expands - this is what gives the omni its gain. Top Side antenna 0 gain gain Think of Yagi antennas in terms of focusing, with low gain yagis having a wide focus and higher gain yagis having a narrower and narrower focus. A good analogy is that of light. An omni antenna is a like light bulb (sending out its light in all directions - see above) A low gain yagi is like a street lamp (focused yet broad) A mid gain yagi like a flashlight (more focus) A high gain yagi like a lighthouse (very directional with good distance) Note: the more focused the yagi becomes, the more critical aiming is, so avoid wiggly antenna poles. 3 db 6 db 10 db

9 Basic Network Considerations

10 Product Considerations

11 $$$ Considerations

12 Communication Network Strategies

13 Mixed Radio Network Strategies

14 Hybrid Systems often have several radio and technology types deployed This SCADA Network has a mix of both licensed and SS Radios from three different radio manufacturers. This network also combines TCP/IP and Serial Data into one SCADA Host Software.

15 Radio Communication Networks

16 Radio SCADA Networks From small to large - the design and planning will be the same.

17 Unlicensed or Licensed 5, 6, 11GHz Microwave Networks 11GHz Licensed Radio and the HTP IP Radio to tap into the serial network 5.8GHz SS Radio using The HTP IP Radio to tap into the serial network

18 VSAT Satellites and HT Plus radios HTP radio can connect to the Satellite Terminal and you can have a sub network of SS IP and SS Serial Radios connected to the Earth Hub.

19 New field with cell coverage - install one cell modem and piggy back a SS Serial radio until your radio network is built out to the new area and the infrastructure is built up. FGR2 Series

20 Cost Savings using I/O and Serial Radios You can combine your IP and serial data network with your I/O sites!

21 Wireless I/O Foundation of Wireless I/O is license-free 900MHz spread spectrum radio technology designed specifically for integration into remote assets and SCADA systems. This technology has been widely used in Water & Waste Water, Irrigation automation and process control for well over 20 years and has proven to be very reliable. The ability to use existing SCADA networks to bring back modbus I/O or stand alone wire replacement systems

22 Wireless I/O advantages Installation Savings (cont d) Reduction in material costs required to hardwire assets Speed of deployment Hazardous environments

23 Wireless I/O advantages Economies of Scale Deploying additional points in a Wireless I/O network is incremental. Capacity is increased by adding I/O slaves and sharing common I/O Master Pay-as-you-go architecture

24 Plunger Lift using I/O Radios 1 Wellhead can have 7 or more signals & a 10 wellhead pad can have up to 70 signals coming back to the EFM/RTU Casing Pressure Tubing Pressure Intermediate P. Surface Pressure Plunger Arrival Open Valve Close Valve AI-1 AI-2 AI-3 AI-4 DI-1 DO-1 DO-2

25 Cost Savings using TCP/IP & Serial Radios

26 FGRplus & HTplus Product Definition IP/Ethernet radio from 115 to 867Kbps depending on Radio type Superior interference rejection Range is up to miles w/clear RF LOS 128 bit AES Encryption RADIUS Central Authentication VLAN tagging MAC filtering -40 to + 60 C Temperature range Multiple protocol, Serial & Ethernet Gateway (aka Access Point ), Repeater or End Point in one radio User Configurable

27 Hybrid Solution using Ethernet, Serial and IO Radios

28 Swiss Army Knife - Toolsuite

29 Toolsuite Design Template

30 Conclusion: Hybrid networks can have several variations of radio type, freq. licensed or spread spectrum Ethernet, serial and I/O can all work together. Mixing two or three brands or technology is common upgrade critical sites when needed and add new technology when needed to get the biggest bang for the buck! Do your homework check references, products, features, warranties, get a path study, can you easily get diagnostic and history information? Define short and long term goals, network data requirements and plan for future growth and network expansion. Check your tackle box!
