Core Responsibilities

Primary Functions

  • Lead radio network design tasks including site selection, cell layout, frequency assignment and antenna configuration to meet coverage, capacity and handover targets for LTE and 5G NR networks.
  • Develop and maintain detailed propagation models and simulations (Atoll, Planet, ICS, iBwave) using topography, clutter data and building footprints to predict outdoor and indoor coverage and performance.
  • Produce complete link budget calculations, path loss analyses and interference studies that quantify expected signal levels, margins and cell edge performance under multiple load scenarios.
  • Specify antenna systems, downtilt, azimuth, electrical and mechanical mounting requirements and prepare antenna schedules aligned to tower structure and civil constraints.
  • Design and document Distributed Antenna Systems (DAS), small cell deployments and indoor coverage solutions, including antenna placement, cabling, headend location and passive/active component lists.
  • Conduct and analyze drive test and walk test data (TEMS, Actix, Nemo) to validate model predictions, identify coverage gaps and prioritize remediation or redesign work.
  • Perform capacity planning and traffic modelling to size RAN resources, spectrum assignments and carrier aggregation strategies that support short- and long-term traffic growth.
  • Configure and validate MIMO, beamforming and Massive MIMO parameters in design models to ensure expected throughput and spectral efficiency gains for 4G/5G services.
  • Prepare detailed network design documentation, site installation drawings, RF design reports, Bills of Materials (BOM), and construction-ready design packages for field teams and vendors.
  • Collaborate with planning, optimization, transport and core teams to ensure designs align with backhaul constraints, latency targets and end-to-end service requirements.
  • Coordinate with tower owners, landlords, municipalities and regulatory bodies to gather site constraints, obtain permits and ensure designs meet local regulations and safety codes.
  • Engage with vendors and integrators to evaluate equipment options, assess vendor drawings, approve site-specific BOMs and negotiate installation and integration work scopes.
  • Support feasibility studies for new sites, site swaps, co-location and tower reinforcements by producing structural, RF and cost-impact analysis and recommendations.
  • Model and mitigate inter-cell interference and adjacent channel interference through frequency reuse, power control, antenna selection and tilting strategies.
  • Validate radio parameter and configuration settings on the network (CSI, RSRP/RSRQ thresholds, TAC/PCI planning) and handover matrices to reduce dropped calls and signaling issues.
  • Run sensitivity analyses and design trade-offs (coverage vs capacity vs cost) and present recommended options to product owners, program managers and stakeholders.
  • Contribute to network rollout plans including milestones, resource estimates, risk logs and acceptance criteria for new builds, technology refreshes and densification programs.
  • Provide on-call design support for build teams during construction and commissioning phases to resolve design-to-field discrepancies and expedite site acceptance.
  • Maintain and update RF design repositories, GIS layers and asset databases (iBwave database, network inventory) to reflect actual deployed configurations and design revisions.
  • Drive continuous improvement by incorporating field feedback, post-deployment performance metrics and optimization learnings back into design heuristics and templates.
  • Ensure compliance with RF exposure (EMF), safety, and zoning regulations by producing required documentation and coordinating site-level safety compliance checks.
  • Mentor junior designers and create design guidelines, templates, and knowledge transfer materials to standardize designs and accelerate team ramp-up.
  • Estimate implementation cost impacts and prepare comparative analyses for technology options (e.g., FDD vs TDD, small cell vs macro, mid-band vs mmWave) to support investment decisions.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis.
  • Contribute to the organization's data strategy and roadmap.
  • Collaborate with business units to translate data needs into engineering requirements.
  • Participate in sprint planning and agile ceremonies within the data engineering team.
  • Provide input to RF testing plans and acceptance criteria for vendor and field test campaigns.
  • Assist procurement in evaluating vendor RF drawings, equipment specifications and commercial offerings from an RF design perspective.
  • Review and approve change requests for design alterations and capacity upgrades during project execution.
