Metropolitan Smart Grid: Bridging Legacy Infrastructure with 5G Edge Computing
Rolling out 100,000 smart meter acquisition points across a LATAM urban grid.
01 / Operational Background
A major city in Latin America with 2 million residents. The electricity provider needed to modernize their data collection for legacy meters tucked into hard-to-reach electrical cabinets.
02 / Status Quo & Challenges
Previous Operational Mode:
Meter readers used standard smartphones that lacked specialized infrared (IR) ports. This forced manual entry, leading to billing disputes and a 12% revenue leakage due to undetected meter tampering.
Proprietary Protocols: Legacy meters required specific high-speed infrared handshakes not found on commercial PDAs.
Urban Dust: Lenses on acquisition hardware were frequently scratched or clouded by urban particulate matter.
Billing Disputes: Customers often disputed manual readings, requiring a physical evidence-based onsite receipt.
03 / Engineering Interventions
Custom Utility PDA: Developed the SIGAN 608 with an integrated high-speed IR port and an 80mm thermal printer.
Edge Sync: Built-in 5G modules allowed instant uploading of meter evidence to the municipal cloud.
Sealed Optics: Engineered a recessed IR window with scratch-resistant sapphire glass to survive high-dust zones.
04 / Quantified Operational Impact
Billing dispute rates dropped by within the first quarter of rollout.
Read success on first-attempt acquisition, eliminating costly site re-visits.
Detected $.2M in annual revenue loss due to meter tampering in the first 6 months.
"SIGAN's willingness to integrate a printer and an IR port on one rugged chassis saved our municipal billing project."
