LASRRA - Long Distance Point-to-Point

Wireless link analysis and connectivity report between Alausa (Ikeja) and Library (Sangotedo) for LASRRA network expansion.

LASRRA Point-to-Point Link

Project Overview

This project involved conducting a long-distance wireless point-to-point link analysis for the Lagos State Residents Registration Agency (LASRRA). The goal was to establish a viable line-of-sight connection between Alausa, Ikeja (Point 1) and Library, Sangotedo (Point 2) using standard field measurement tools.

The assessment was complemented by reference landmarks including Crusader House, Oyingbo, and Tinubu Square to validate the accuracy of the GNSS readings and to enhance coordinate reliability.

Equipment Used: GNSS Handheld Unit (GPS), Compass, Inclinometer, Binoculars

Wireless Link Analysis Report

Bearing from Point 1 (Alausa, Ikeja)
  • Point 2 → 121° , 34.99 km
  • Crusader House → 175° , 12.54 km
  • Oyingbo → 173° , 15.44 km
  • Tinubu Square → 173° , 18.57 km
Bearing from Point 2 (Library, Sangotedo)
  • Point 1 → 301° , 34.99 km
  • Crusader House → 281° , 29.37 km
  • Oyingbo → 276° , 28.23 km
  • Tinubu Square → 292° , 27.63 km

Measurements were verified with GNSS positioning and optical alignment checks.

Technical Notes

A positional error margin of ±25 metres was observed, corresponding to approximately 0.026%, well within the acceptable tolerance of ±2% for long-range GNSS-based measurements. Variations were attributed to atmospheric conditions and the visible satellite constellation at the time of measurement.

Crusader House, Oyingbo, and Tinubu Square were included as reference landmarks for coordinate validation only.
