Utility Systems Science & Software Principles has been providing Radio Path Surveys for the wireless Supervisory Control and Data Acquisition (SCADA) industry, including North America, Middle East and South East Asia for more than 20 years. We conduct detailed radio path studies in order to determine the feasibility of radio communications for your SCADA system. The study involves both a topographic map and sight assessment, including an onsite radio link test between the Master PLC or Master Station, Repeater, Store & Forward and every remote location.

The path calculations and test results are used to help select the most reliable communication path for the SCADA system including the following:

  • Communications technology (VHF, UHF, Spread Spectrum, 800 Trunk, 2.4, 4.3 and 5.8 Ghz)
  • IP Interfaces for localized radio links into WiMax, Fiber and Broadband Networks
  • Repeater requirements
  • Antenna/tower heights
  • Antenna type and gain

As part of the Radio Path Study, US3 will determine the exact type of antenna that will be used as a function of station coordinates, path topology, and any obstructions. The result will include:

  • Antenna types
  • Omni-directional antennas
  • Semi-directional antennas
  • Highly directional antennas
  • Phased array antennas
  • Sector antennas
  • Antenna accessories
  • Cables
  • Connectors
  • Splitters
  • Amplifiers
  • Attenuators
  • Lightning arrestors
  • Grounding rods and wires
  • Antenna polarization
  • Antenna connection and installation
  • Voltage standing wave ratio (VSWR)
  • Signal loss
  • Antenna mounting

Upon completion of the survey, you will be provided with a detailed report with recommendations that provide a communications system designed for a SCADA system in the Utility Industry.

Narrowbanding FCC Mandate
In an effort to promote greater spectrum efficiency, the FCC is requiring all Public Safety and Industrial/Business licensees using 25 kHz VHF and UHF radios systems migrate to minimum 12.5 kHz efficiency by January 1, 2013

US3 is here to help you prepare for a smooth and cost-effective transition. While Motorola radios purchased in the last ten years are likely dual-mode 25/12.5 kHz, older equipment may need to be replaced.

Increase Capacity or TDMA Efficiency
Increase capacity and meet the Narrowbanding mandate without applying for a second channel. Motorola is shipping two complete product families; ASTRO 25 APX radios for mission critical applications and the MOTOTRBO series for business critical applications that provide greater than 12.5 kHz efficiency.

Transition at Your Own Pace
Motorola radios are backwards compatible so they can operate in dual mode (12.5 kHz or 25 kHz), allowing your organization to transition to 12.5 kHz at your own pace up to the FCC deadline.
