Description:
Job Purpose:
Establishes RF communications systems by determining radio environment; identifying, evaluating, and developing sites; developing and implementing radio frequency (RF) designs; verifying and optimizing performance.

Duties:
* Determines radio environment by preparing base maps; identifying and analyzing propagation environment; collecting and studying terrain, roads, and demographics data; evaluating similar systems; identifying and establishing performance and quality standards.

* Develops RF engineering design project by developing project concepts and objectives including demand criteria, coverage, and number of channels; preparing a project plan, including required resources, development timetables, cost estimates, link budgets, etc.; identifying short-term and long-range issues; qualifying contractors and vendors.

* Identifies sites by preparing site coverage studies; producing "search ring" maps; visiting potential sites; validating measurement data, including location, radiation center above ground, antenna placement, and line of sight conditions; evaluating signal propagation environment; defining leasing, zoning, and construction issues.

* Designs and constructs RF systems by researching, analyzing, selecting, and applying RF engineering techniques and criteria; adapting and modifying RF engineering approaches and options; developing and evaluating new RF engineering approaches; preparing maps and schematics; configuring the system; characterizing the path loss; calibrating the signal propagation model; developing a network simulation including traffic and loading analysis; completing code division multiple access (CDMA) including assignment of pseudo-noise (PN) short-code offsets; selecting and approving equipment; supervising installation of equipment and construction by contractors; preparing site acquisition request forms (SCARs); analyzing potential obstruction to air navigation, including obtaining Determination of No Hazard from the Federal Aviation Administration (FAA); determining and establishing RF engineering design specifications and safety standards.

* Verifies RF performance by completing drive test studies; analyzing drive test data; updating and optimizing the propagation model; applying figures from link budgets; identifying interference areas; changing system configuration and hardware/software parameters.

* Documents RF design by recording engineering design features, functions, and operational requirements; specifying operational training; detailing safety requirements; preparing Federal Communications Commission (FCC) filings and notifications.

* Maintains engineering design team accomplishments by coordinating actions; reviewing open issues and action items; contributing information and engineering analysis to team meetings and reports.

* Improves RF design by reducing interference; optimizing network performance; evaluating switch data and expansion of coverage; planning capacity.

* Prepares engineering reports by collecting, analyzing, and summarizing data and trends.

* Updates job knowledge by tracking and understanding emerging RF engineering technologies and practices; participating in educational opportunities and professional organizations; reading professional publications; maintaining personal networks.

* Enhances engineering and organization reputation by accepting ownership for accomplishing new and different requests; exploring opportunities to add value to job accomplishments.
