Smart City MeshSens

Smart City
on Mesh Network Without Gateways

Q: How is MeshSens different from LoRaWAN in a city?

In LoRaWAN, every sensor sends data to a base station — if it fails, the entire segment goes blind. In MeshSens, every device is a relay: signals hop node to node through lobbies, floors, and courtyards. No gateway — no vulnerability.

Q: How does Mesh work in high-rise buildings?

A smoke detector in an apartment relays through the nearest hallway node. That node relays through the next floor or rooftop. Concrete floors are bypassed via intermediate nodes. Each new sensor improves coverage.

Q: How fast does an alarm arrive?

Under 3 seconds from sensor trigger to dispatcher notification. Automatic broadcast via SMS, Telegram, email, and push notifications.

Q: What safety sensors are supported?

Smoke Detector, Alarm Button (panic), Leak Detector, door/hatch open sensor (Dry Contact), relay control (Dry Contact Relay), temperature and humidity sensors.

Q: Is internet required?

The Mesh network operates autonomously. One edge node connects via Ethernet or LTE to send data to the ROSSMA.NETS cloud. If internet goes down, the network keeps running and buffers data.

Q: How many devices can be connected?

Up to 50 nodes per cluster. Clusters interconnect — total network scales to 500+ points. A 100-building district needs 5–10 clusters.

Q: What is the sensor battery life?

Smoke detector — up to 10 years. Panic button — up to 5 years. MeshSens with solar panel — unlimited. Range −40 to +85 °C, IP65.

Q: Can it integrate with city management systems?

Yes. ROSSMA.NETS integrates via REST API and MQTT with smart city platforms, emergency dispatch (112), and municipal management systems.

Fire safety, security, environmental monitoring — powered by ROSSMA MeshSens self-organizing Mesh network. Every device is a relay. No base stations, no SIM cards, no monthly fees. The network covers lobbies, basements, and entire neighborhoods

Why Traditional IoT Fails in Cities

Gateways, SIM cards, and blind spots — not designed for urban environments

Fire Safety Without Connectivity

Smoke detectors without IoT only sound a local alarm. Dispatch learns about fires from residents — minutes or hours later, not seconds.

Gateways — Single Point of Failure

LoRaWAN systems depend on base stations. If a gateway fails, the entire monitoring segment goes dark: fire, security, and environmental sensors.

No Centralized Monitoring

Fire alarms, security, leaks, environment — separate silos. No unified view of building, block, or district status.

Slow Emergency Response

Without automated alerting, incident-to-response time is measured in hours. Damage from fire, flooding, or break-in grows exponentially.

NB-IoT/GSM Monthly Fees

Every SIM-equipped sensor costs $2-3/month. At 1,000 points per district — up to $3,000/month forever.

Blind Spots in Lobbies and Basements

Concrete floors, steel doors, and underground utilities block LoRaWAN and cellular signals. The most vulnerable locations have no coverage.

MeshSens — Smart City Without Gateways

Every device extends the network. Fire, security, and environmental IoT — in one Mesh network

Mesh Without Base Stations

Every MeshSens is a transceiver at 868 MHz. A smoke detector in an apartment relays through a hallway node, which relays through a rooftop node. The network builds itself, covering lobbies, basements, and courtyards.

IoT Fire Alarm

ROSSMA Smoke Detector transmits alarm in <3 seconds through the Mesh network. Automatic notification to dispatch, fire department, and residents via SMS, Telegram, email.

Security & Panic Buttons

ROSSMA Alarm Button in lobbies, parks, social facilities. Instant alert with coordinates. Door/hatch open sensors, valve monitors — wireless access control.

$0/mo — No Hidden Costs

No SIM cards — no cellular fees. No gateways — no infrastructure costs. 868 MHz ISM band — license-free. Pay once for hardware — works for years.

Environmental Monitoring

Temperature, humidity, leaks, gas detection. Basement, server room, substation, and outdoor monitoring. Early warning of incidents and parameter exceedances.

ROSSMA.NETS Platform

All sensor types in one interface: fire, security, environmental, engineering. Facility map, ISA-18.2 alarms, reports, Telegram bot for dispatchers.

Architecture: Mesh Network for a Neighborhood

Every node is a relay. The network covers lobbies, basements, and courtyards without a single gateway
