Job Title: RF Engineer

Duration: 06+ months with a possible extension based on your performance (only W2)

Location: Little Rock, AR

The RF Engineer is responsible for contributing in the RF Design of the regional wireless network. Responsibilities include but are not limited to:
• Creates search areas and reviews search area candidates within geographic area by taking into consideration baseline, performance issues, capacity, topography, and population.
• Working with the performance team to improve Key Performance Indicators within his/her area.
• Working with traffic and implementation counterparts to understand capacity improvements needed in the network.
• Create site design RFDS and complete plumbing diagrams.
• Evaluate antennas and equipment for performance and future growth.
• Performing radio engineering evaluations for system planning and site acquisition.
• Evaluating coverage problems and requirements for coverage and capacity cells.
• Utilizes propagation tools and other RF related equipment such as MapInfo, GeoPlan, ATOLL, Datapro and Nortel Performance Tool 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.
• Prepares necessary zoning/regulatory filings for sites ensuring that compliance is met, and attends zoning meetings for assigned area as required.
• Works closely with real estate team to increase efficiency, minimize cost, and streamline processes related to site acquisition, leasing, and zoning submissions.
• Review real estate applications for accuracy prior to lease execution.
• Conduct RFE analysis, generate required reports and documents, and ensure 100% compliance to RFE mitigation standards within the allotted time frame.
• Generate and evaluate coverage and interference prediction maps.
• Calculate and evaluate the effects on the received signal of path-related impairments.
• 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.
• Ensure 100% regulatory requirements are met in every phase of design project.
• Evaluate site compliance with health, safety, and environmental requirements.
• Perform intermodulation analyses of antenna systems and components.
• As needed, calculate link budgets to evaluate system performance and reliability based on received signal level and fade margin.
• Calculate the efficiency of various multiple-antenna schemes, and analyze the tradeoffs involved in selecting from among them.
• Evaluate the effects of path loss on the received signal strength in various signal propagation environments (examples might include flat terrain, rolling hills, urbanized areas, and indoor environments [such as buildings or tunnels] with losses caused by walls, ceilings, etc.).
• Determine parameters related to antennas (examples might include pattern, beam width, gain, distance from an antenna or array at which far field conditions apply, spacing, beam forming, tilt, and sectorization) and analyze the effects of these parameters on coverage and capacity.
• Generate and evaluate coverage and interference prediction maps.
• Analyze propagation modeling and “drive test” measurements and make recommendations for site optimizations.
• Analyze design considerations and perform system design to eliminate coverage holes and to optimize capacity/coverage.
• Evaluate site design efficiency related to handover/handoff management and inter-technology handover/handoff.
