SOLAR TODO delivered a 267-unit Smart Streetlight deployment across Ahmedabad, India, using a seamless, pole-integrated 10-in-1 configuration designed for dense urban corridors and strict visual/maintenance requirements.
Answer Capsule: In Ahmedabad’s busy streets, SOLAR TODO installed 267 smart streetlights at 25m spacing, integrating 12-parameter environmental sensing, IP audio/SOS, 2MP flush camera, and 5G small-cell readiness with edge-cloud management.
Project Overview: Smart Streetlight for Ahmedabad’s Urban Mobility and Safety
Ahmedabad’s street network carries high pedestrian and vehicle volumes, while public works teams face recurring challenges: uneven lighting visibility, fragmented city sensing, and the operational overhead of maintaining separate devices (cameras, speakers, sensors, and connectivity). Additionally, telecom densification increasingly demands street-level coverage without adding bulky structures that conflict with road furniture and aesthetic guidelines.
To address these constraints, SOLAR TODO deployed a standardized Smart Streetlight pole platform engineered for clean, seamless installation and multi-service city operations. The system is built around a 12m Φ168mm (wall 5mm) hot-dip galvanized steel pole, finished in dark grey (RAL 7016 powder coat) with a seamless cylindrical profile—a form factor that simplifies alignment, reduces protrusion risk, and improves long-term maintainability.
The deployment integrates perception (camera + environmental sensing), communications (WiFi 6 + 5G small cell ready + LoRaWAN/4G controller), safety (IP audio column with SOS intercom), and public connectivity (USB charging), all managed through a cloud platform and smart edge gateway.

Deployment Design: Seamless Pole Integration Across Ahmedabad
SOLAR TODO’s engineering approach for Ahmedabad emphasized a single, repeatable pole architecture to reduce variation across street segments. Each pole was manufactured as a clean monolithic cylinder with flush-mounted or minimal clamp-mounted modules to prevent maintenance issues common to multi-part roadside structures.
1) Integrated lighting head for consistent roadway illumination
Instead of using an external arm bracket, the light head is integrated with the pole body. A circular PMMA diffuser dome (Φ168mm) sits flush on the top, matching the pole diameter. This integration supports a controlled downward distribution and helps keep the silhouette uniform along the corridor—important in Ahmedabad where road furniture and signage are frequently placed near lighting assets.
2) Flush camera for street safety without adding visual clutter
The 2MP 180° mini dome camera is embedded inside the pole body and rated IP67, with no protrusion. This reduces tampering risk and prevents wind-load amplification associated with external camera housings.
3) 12-parameter environmental monitoring for air-quality and comfort analytics
Ahmedabad experiences periods of variable particulate levels and localized microclimate effects. The top module uses a 12-parameter ENV sensor capturing temperature, humidity, wind, pressure, noise, PM2.5, PM10, CO, NO2, O3, rain, and illuminance.
This sensor set supports city operations that need both air-quality signals and context (e.g., rain and wind affecting dispersion and sensor interpretation). The system’s data is delivered through the smart edge gateway and remote cloud platform for centralized monitoring.
4) IP audio column + SOS intercom for immediate public safety response
The IP audio column (30W, 93dB) is deployed as a networked cylindrical unit using TCP/IP. It includes an SOS intercom, enabling quick escalation for pedestrians and residents. This is especially valuable where street crossings, bus stops, and community entrances require rapid on-site communication.
5) Connectivity stack designed for dense urban corridors
Each pole includes a WiFi 6 AP for localized connectivity and a smart edge gateway with GbE + 4G/5G + edge AI computing + LoRaWAN. This design supports:
- local edge processing (reducing round-trip latency for camera/sensor events)
- resilient connectivity via multiple uplink options (4G/5G + GbE where available)
- long-range low-power telemetry using LoRaWAN for sensor data distribution
Additionally, the poles are configured with 5G NR n78 small cell readiness using a 4T4R MIMO configuration designed for 200m coverage, supporting telecom densification without requiring separate tower structures.
6) Public service utility: USB charging + e-bike/scooter charging
To support last-mile mobility, the pole assembly includes:
- USB phone charging port: 5V/2.4A × 2
- e-bike/scooter charging station: 10 outlets, 220V/10A
These features convert streetlight infrastructure into a multi-use urban asset—helpful for areas with frequent micro-mobility activity.
Power & Control Architecture for Operational Continuity
While the deployment is grid-powered (AC), SOLAR TODO’s pole design includes an integrated energy subsystem to support stable controller operation and system resilience.
- CIGS thin-film solar cells are wrapped around the pole mid-section (~240W), with no protruding panels to protect the asset from vandalism and reduce aerodynamic stress.
- An LFP battery (3000Wh) is installed inside the pole base, managed by an MPPT controller.
At the control layer, the system uses a smart controller supporting LoRaWAN/4G, while the smart edge gateway handles multi-network uplinks and edge AI computing. Together with the cloud platform, this architecture enables remote monitoring, diagnostics, and operational updates.
Standards and Compliance Rationale
SOLAR TODO designed and deployed the Ahmedabad Smart Streetlight configuration with international and local standards in mind:
- IEC 60598 for luminaire safety and performance expectations
- GB/T 37024 for LED luminaire-related requirements
- CJJ 45-2015 for relevant municipal roadway lighting considerations
These standards align with the broader global approach to street lighting safety, environmental durability, and reliability.
Results and Impact
Over the deployment footprint, SOLAR TODO delivered measurable operational improvements by combining lighting, sensing, safety communications, and connectivity into one managed infrastructure layer.
- 267 smart streetlights installed with a standardized 12m Φ168mm pole platform.
- 25m spacing ensured consistent coverage along the corridor segments while keeping the streetscape uniform.
- Each pole provides 100W / 15000 lm at 4000K (150 lm/W) with a flush Φ168mm PMMA diffuser dome, supporting controlled downward illumination.
- 2MP 180° flush-embedded camera (IP67) at each unit improves situational awareness without adding protruding hardware.
- 12-parameter environmental sensing (including PM2.5/PM10, CO/NO2/O3, rain, illuminance) enables richer city analytics than single-sensor deployments.
- IP audio column (30W, 93dB) with SOS intercom provides a direct safety channel for pedestrians.
- WiFi 6 AP + smart edge gateway (GbE + 4G/5G + edge AI + LoRaWAN) improves data handling and remote operations.
- 5G NR n78 small cell readiness (4T4R MIMO, 200m coverage) supports future telecom densification planning.
- Integrated public services: USB 5V/2.4A ×2 and 10-outlet 220V/10A e-bike/scooter charging.
Beyond hardware consolidation, the key impact is operational: city stakeholders gain a single managed asset per location—lighting plus sensing plus communications—reducing fragmentation across maintenance teams.
