Tom Eckels has more than 30 years of professional experience in analysis and system planning, design and specifications, compatibility assessments, measurements, and recommendations for antenna and radio design projects. As a project manager he is noted for keeping projects on schedule and under budget while delivering a high-quality technical product.

Mr. Eckels has extensive project management experience with both transit and public-safety two-way voice and data radio system design and implementation, needs analysis for public safety and transit agencies, and spectrum allocation issues in the land-mobile bands from VHF to 900 MHz. Mr. Eckelsí experience with project management includes facilitation of the process to address opinions and requirements of stakeholders, interested parties, and multiple public agencies as users and funding partners. He has the proven ability to manage complex issues with multiple and sometimes conflicting user demands.

His background includes analysis of electromagnetic compatibility at multiple-use communications sites and airports including: analysis of compatibility of high-power FM broadcast and UHF TV operation with land-mobile base station and mobile operation; design, specification, and implementation of transit and public-safety radio systems; and analysis of complex spectrum allocation issues and their impact on radio system design and implementation.

Mr. Eckels has been involved in projects involving feasibility studies, radio system design and specification, propagation measurements, planning, and electromagnetic compatibility and interference analysis.

Representative Projects

  • Project Manager and technical director for the University of Washington Hospital survey of the "lossy line" distribution system, which required redesign of the system to fit it with wideband splitters, appropriate amplifiers, and radiating antennas to provide more uniform signal strength in the lower floors of the hospital complex.
  • Senior Engineer for the State of Nevada, Department of Information Services, study of the microwave and mobile radio systems that serve the various agencies for the state, local community public-safety agencies, and public utilities. This 10-phase study covered analysis of the existing systems, propagation studies of 48 sites, alternatives for interconnections, alternatives for interoperability, applicability of various emerging technologies, impacts of FCC and PSWAC activities, and final recommendations.
  • Senior Engineer for the statewide RF communications project for the State of Illinois to study the mobile radio systems and usage for all state agencies, including 23 agencies and more than 30,000 mobile units. The project involved surveying applications and equipment, developing a needs analysis, and preparing alternative plans and cost estimates.
  • Project Manager for the Port of Seattle two-way radio project, which included analysis and facility design, propagation measurements, repeater design, microwave system design, and system planning.
  • Project Manager for a feasibility study sponsored by the Washington State Legislative Transportation Committee to assess the savings and efficiencies of consolidating its transportation agency wireless communications facilities, including mobile radio and microwave interconnect systems.
  • Senior Engineer for the Springfield, OR, project to design a new radio system and 9-1-1 communications center for the Police Department. The project involved a detailed survey of the existing system, preparing a needs analysis, and propagation mapping to determine the optimum site for a new repeater station.
  • Project Manager for the East Butte, ID, trunked system intermodulation analysis, which involved installation of a new 20-channel trunked 406 MHz radio system. The project addressed concerns about intermodulation interference and electromagnetic incompatibility between existing users and the proposed operation, and demonstrated that the proposed system would operate satisfactorily without adversely impacting pre-existing users.
  • Project Manager for a complete analysis of the potential for interference between a new ESMR transmission facility operating in the 851-869 MHz band with the existing low band VHF, high band VHF, UHF, 800 MHz, microwave, and CATV headend facilities in the Little Mountain Communications site near Mount Vernon, WA.
  • Project Manager for a study to resolve interference problems at the Mt. Morrison, CO, transmitter station used by station KTVD. Participated in initial investigations and on-site work required to resolve the interference problems.
  • Project Manager and technical consultant for comprehensive propagation analysis, data reduction, and prediction method development for projects in Singapore and Los Angeles, CA.
  • Technical consultant to the State of Nevada for analysis and recommendations for a statewide microwave interconnect system for public safety, education, and government agencies.
  • Technical consultant for the feasibility co-site interference study of the existing 800 MHz public safety two-way radio systems and proposed cellular and PCS systems at the Denver International Airport.
  • Project Manager for the City of Everett, WA, Housing Authority project to perform analysis and make recommendations for a proposed 800 MHz trunked radio system.
