Brian has over 11 years of experience in telecommunications and electrical engineering.He is a registered professional electrical engineer and has a variety of experience in utility and telecommunications.Brian specializes in the engineering and implementation of radio, cable and fiber optic systems for private and public networks.He managed the channelization effort of a private communications network, covering five states, where he developed design standards and was responsible for the design of over 700 voice and data circuits used for administration and operations of an electric utility.Brian has particular expertise in microwave system design, RF engineering, digital and analog multiplex, DC power plants and grounding systems.
PROFESSIONAL EXPERIENCE
Brian designed an 18GHz system between two electric utility dispatch centers.The objective was to provide a reliable system, using a pair of radios already owned by the client.The path was relatively long for 18GHz, requiring special effort to provide adequate fade margin.The design combined rigid waveguide and smaller antennas to provide improved fade margin and forgiving antenna pattern.Brian also oversaw the development of all installation documentation and provided assistance during installation.
Compressor Station #4 Microwave Project for Pacific
Gas Transmission,
Brian was responsible for inspecting an existing microwave system to determine the cause of poor received signal level.He developed a procedure to determine the effect of a potentially interfering structure, and modeled a path obstruction, determining a new antenna mounting height to optimize performance of the system.Brian also provided a redesign of an adjacent path, furnishing data for the addition of space diversity and the realignment of double passive reflectors.
Microwave Inspections and Evaluation for
Brian inspected and evaluated a 10 site, 2GHz microwave network for Douglas County, Oregon. This project required the evaluation of the entire communications system including site facilities, AC and DC power systems, multiplexers, radios, alarm interfaces, and ancillary electronic and mechanical support systems.
South Hill Microwave System Project for PacifiCorp,
Brian designed a 2-hop system of 960MHz analog and 10GHz digital to connect an electrical substation to an existing digital microwave backbone.The 960MHz path was designed to be obstructed to minimize tower height while retaining adequate fade margin.The diffractive path proved to be within 1 dB of predicted after installation.Both paths of the system continue to meet the reliability criteria set by the client.
Microwave System Design for Western Wireless,
Brian designed an 8 hop 3-DS3 system to support a Cellular PCS network.The system was designed to support cell sites, switches, and outside trunking.The design was optimized to support a large number of low capacity spurs to cell sites while minimizing the number of broadband backbone hops.He also provided assistance during the budgeting process.
Digital
Synchronization System Project for PacifiCorp,
Brian designed an extensive synchronization system for a large digital communications network, and continued to evaluate and modify the system as the network expanded over a three-year period.He developed a robust system, consisting of a GPS-referenced rubidium clock supporting a number of redundant, oven-stabilized clocks.Brian provided installation documentation and technician support during installation and configuration of the multiplex.
Cellular
RF Engineering for Western Wireless (VoiceStream),
Brian was responsible for the RF design of Cellular PCS base stations.He used a computerized cellar design tool (CellCAD), and coordinated with Site Acquisition and Construction personnel regarding site selection and design documentation.Brian was responsible for engineering approval of electrical drawings for construction.
Radio
System Engineering
Brian
was responsible for radio system planning, design and implementation, and
digital and analog microwave system design.His
work also included path surveys and design for various microwave systems,
coverage studies for land mobile systems, cellular Network RF Design and
Optimization and preparation of FCC, FAA, and coordination forms.
Field
Support
Brian was responsible for scheduling and coordination of installations, procurement of communications equipment, preparation of detailed system installation instructions, and valuation and troubleshooting of existing and new systems.
Cellular Optimization
Brian was responsible for the optimization of cell sites and network parameters.He tracked network statistics and trouble tickets, and conducted field inspections of operating cell sites.Brian also issued work orders for antenna system upgrades, repairs and other improvement, and tailored network parameters (hand-off thresholds, etc.) to enhance system operation.
Microwave
Path and Antenna Systems
Brian prepared path budgets and conducted path surveys.He recommended tower locations and heights with regard to reliability criteria and cost savings and designed antenna systems including waveguide, pressurization, and ancillary hardware.Brian also provided pertinent technical data for preparation of license applications for several projects.
Wasco
Analog Baseband Upgrade for PacifiCorp,
Brian evaluated an existing analog microwave system baseband.He proposed modifications to optimize performance of broadband data modems (T1 and 216 kBit), and redesigned the baseband at several sites, provided detailed installation instructions as well as provided day-to-day technical support to the field during installation.
