Network design

Radio & backhaul HLD/LLD

Multi-level design to ensure scalability and CAPEX/OPEX optimisation.

High-Level Design (HLD)

  • Overall network architecture (RAN, Transport, Core)
  • Multi-band frequency strategy (700/900/1800/2100/2600 MHz)
  • Technology roadmap (2G sunset → 5G standalone)
  • Target capacity per area (GB/month, active subscribers)

Low-Level Design (LLD)

  • Site-by-site files (GPS coordinates, azimuths, tilts)
  • Detailed link budget (antenna gains, propagation losses)
  • TRX/sector count dimensioning per site
  • Neighbour engineering (adjacency lists, handover, ANR)

Smart optimisation

SON (Self-Organising Networks)

Radio parameter automation to ensure optimal QoS and spectral efficiency.

MLB (Mobility Load Balancing)

  • Inter-frequency & inter-RAT load distribution based on congestion
  • Dynamic handover threshold tuning (A3 offset, hysteresis)
  • 3G/4G traffic balancing in co-coverage areas

MRO (Mobility Robustness Optimisation)

  • Reduction of HO failures, ping-pong and RLF via automatic tuning
  • TTT (Time To Trigger) and CIO (Cell Individual Offset) optimisation
  • Detection of neighbour issues (missing/wrong neighbours)

CCO (Coverage & Capacity Optimisation)

  • Pilot power auto-tuning (CPICH, RS EPRE)
  • RACH parameter and admission control adjustment
  • Interference management (ICIC, eICIC for HetNets)

Financial planning

3-5 year CAPEX/OPEX dimensioning

Investment and operating cost modelling for a sustainable master plan.

CAPEX (investments)

  • Sites: BBU, RRU, antennas, cables, civil works
  • Transmission: MW hops, fibres, aggregators
  • Core: EPC/5GC, IMS, HSS, software licences
  • Tools: SON, OSS/BSS, OMC, monitoring

OPEX (annual operations)

  • Sites: energy, rentals, preventive/curative maintenance
  • Transmission: leased lines, IP transit, backhaul
  • Core: servers, vendor support, licences
  • Teams: consultants, training, continuous optimisation

Modelling & sensitivity

  • Traffic forecasts (voice/data CAGR, 4G/5G penetration)
  • Rollout scenarios (aggressive/moderate/conservative)
  • Sensitivity analysis (site cost, FX rates, ARPU)
  • Business case with IRR, NPV, payback period

Field validation

SSV & acceptance

Standardised post-installation tests to ensure design and SLA compliance.

SSV (Single Site Verification)

  • RF measurements: RSRP, RSRQ, SINR per sector and frequency
  • Throughput tests: max achievable DL/UL vs design
  • Intra/inter-site handover validation, CSFB (4G→2G/3G)
  • OMC alarm screening, configuration parameters

Cluster acceptance

  • Inter-site validation (configured neighbours, HO success ≥98%)
  • Aggregated KPIs per cluster (CSSR, CDR, average throughput)
  • Benchmarking vs adjacent sites or similar areas
  • Load tests (traffic-simulator stress tests)

Acceptance report

  • Dossier with field measurements, OMC screenshots
  • Gap report vs design + tuning recommendations
  • Compliance checklist (alarms, KPI, configuration)
  • Client sign-off after lifting any reservations
