Seamless Smart Streetlight Upgrades: Comark's Ready-to-Deploy Communication Solution

1. What Are Smart Streetlights?
Traditional streetlights provide basic illumination. Smart streetlights transform poles into multifunctional hubs by integrating:
· Audio/video surveillance
· 5G/WiFi hotspots
· Environmental sensors
· EV charging stations
· Digital signage
As key IoT data collection points, they enable smart lighting, security, traffic management, and municipal services while reducing urban clutter.

2. Smart vs. Traditional Streetlights

Traditional	Smart
Single-function lighting	Multifunctional (lighting, surveillance, charging, etc.)
Manual maintenance	Automatic dimming + fault alerts
High energy waste	30-60% energy savings via adaptive control
Space-intensive	Space-saving multi-pole integration
N/A	5G infrastructure carrier

3. Comark’s 3-Step Upgrade Solution

Challenge 1: Protocol Fragmentation
✅ Smart Serial Gateway : Modbus conversion for traditionalcontrollers (zero hardware replacement).
Challenge 2: Outdoor Network Instability
✅ Industrial Switches + Outdoor Wireless AP: IP40-rated, mesh networking, 50% wider coverage.
Challenge 3: Mass Device Management
✅ Edge Computing Gateways: Local data processing → 90% faster response, reduced cloud load.
Result: 60% faster deployment, 40% lower costs vs. traditional trenching/custom protocols.
