Railway Platform Wireless Coverage & Emergency Communication Solution
1. Customer Requirements Analysis
Application Scenario: Railway platform area (approx. 5 km long).
Personnel Scale: Approximately 30 on-site staff.
Core Requirements:
- Data Transmission: Real‑time transmission of on‑site operations to the monitoring center.
- Functions: Two‑way voice communication and GPS positioning.
- Network Coverage: Full wireless coverage supporting LAN data transmission.
2. Solution Design
Based on requirements and site conditions, we provide a hybrid network solution: 4G Body Worn Cameras + WiFi Base Stations, balancing functionality and operational costs.
2.1 Terminal Configuration
Each of the 30 staff members is equipped with a 4G Android Body Worn Device. It supports real‑time video, two‑way intercom, and GPS positioning to fully meet operational needs.
2.2 Cost Control & Network Optimization
Pain Point: Exclusive carrier 4G data leads to high long‑term costs.
Solution: Deploy base stations for WiFi coverage across the platform.
Advantage: 4G body cameras support WiFi. On-site, devices prefer WiFi to avoid high data fees and ensure stable LAN bandwidth.
3. On-Site Deployment Design
This solution provides full wireless coverage for the 5 km platform area.
3.1 Coverage Deployment
- Zone Division: 5 km platform divided into 5 sections.
- Access Points: 5 locations for WiFi coverage.
- Device: Our SF‑5000MS Base Station Wireless Device.
- Antenna: External 120° sector antennas for bidirectional coverage.
- Roaming: All devices use the same SSID for seamless handover.
3.2 Backhaul Connection
Two backhaul options for the 5 WiFi points:
- Option 1 (Fiber): Fiber connection if conditions allow (most stable).
- Option 2 (Wireless): Wireless bridging between base stations if cabling is difficult.

4. Functions & Advantages
Android body cameras connect via WiFi on-site, switch between base stations automatically, and transmit data to the monitoring center.
4.1 Core Functions
- Video Monitoring: Real‑time on-site video transmission via LAN/4G.
- Two-Way Intercom: Real-time voice between command center and field staff.
- GPS Positioning: Real-time staff location tracking.
- Smart Switching: WiFi on-site; auto 4G outside for uninterrupted monitoring.
4.2 Band Advantage
This solution uses 5 GHz WiFi. Compared to 2.4 GHz, 5 GHz offers stronger anti‑interference performance, ideal for railway environments.
