¶ ROSSMA System Architecture
ROSSMA (LLC "Development of Equipment for Communication Systems, Metrology and Automation") is a Russian developer and manufacturer of IoT/IIoT equipment.
Mission: To make automation simpler, easier and more accessible.
Key advantages:
- Battery life up to 10 years (LoRaWAN)
- Service life up to 20 years
- Coverage range up to 45 km
- Low cost of ownership (several times cheaper than GSM/WiFi solutions)
- Unlicensed 868 MHz band (no subscription fee)
- Proprietary ROSSMA IIoT-AMS platform
¶ LPWAN Technologies
ROSSMA uses LPWAN (Low-Power Wide-Area Network) technologies for wireless data transmission:
¶ Technology Comparison
| Parameter | LoRaWAN | NB-IoT |
|---|---|---|
| Spectrum | Unlicensed (868 MHz) | Licensed (carrier networks) |
| Range | up to 45 km | up to 10 km |
| Speed | 0.3–15 Kbps | up to 150 Kbps |
| Battery life | up to 20 years | up to 10 years |
| Subscription fee | No | Yes |
| Network | Own | Carrier |
| Application | Remote sites | Urban infrastructure |
¶ LPWAN Advantages over GSM/WiFi/ZigBee
- Long range — up to 45 km in open terrain
- Low power consumption — battery operation for years
- High penetration — 868 MHz signal passes through obstacles better
- Scalability — thousands of devices per base station
- Low cost — several times cheaper than GSM/WiFi solutions
