Description: The RF Engineer is responsible for contributing in the RF Design of the regional wireless network. Responsibilities include but are not limited to: Create site design RFDS and complete plumbing diagrams. Working with traffic and implementation counterparts to understand capacity improvements needed in the network. Evaluate antennas and equipment for performance and future growth. Perform radio engineering evaluations for system planning and site acquisition. Evaluate coverage problems and requirements for coverage and capacity cells. Utilize propagation tools and other RF related equipment such as MapInfo, Google Earth, ATOLL, for site candidate comparison, propagation and coverage review and selection, zoning and regulatory. Determination of regulatory coverage boundaries for extensions, FAA/FCC filings. Review of cell sites and design for upgrades/modifications. Creates search areas and reviews search area candidates within geographic area by taking into consideration performance issues, capacity, topography, and population. Working with the performance team to improve Key Performance Indicators within the area of interest. Experience with model tuning in propagation tool
Prepare necessary zoning justification packages and regulatory filings for sites. Works closely with real estate team to increase efficiency, minimize cost, and streamline processes related to site acquisition, leasing, and zoning submissions. Conduct RFE analysis, generate required reports and documents, and ensure 100% compliance to RFE mitigation standards within the allotted time frame. Develop and analyze sectors, post construction, to optimize coverage and capacity. Determine the required antennas for planned frequencies and their optimal positions. Determine the required cable, antennas, and equipment to implement macro and small cell wireless network clusters. . Automate processes when opportunities arise and share information with the teams.
