AmbienteTypical Range
Line-of-Sight OutdoorsUp to 1,000 meters (in ideal conditions)
Indoor Residential30 to 100 meters
Controle centralizado para gerenciamento50 to 200 meters with repeaters or boosters
Industrial SettingsCustomized solutions needed due to high interference

3. Typical Operating Ranges: Home, Commercial, and Industrial Applications

In real-world B2B and B2C applications, ranges vary depending on the deployment environment. Understanding these ranges helps dealers and distributors offer the right product according to the customer’s needs.

🏠 Residential Use:

  • Apartamentos e moradias: 30–100 meters indoors with WiFi or RF
  • Outdoor Gates to Indoors: 50–150 meters depending on wall materials

🏢 Commercial Use:

  • Edifícios de escritórios: 100–200 meters depending on floor plans and obstructions
  • Redes de varejo: Ideal for internal security communication
  • Hotels & Resorts: Used for room service and access control

🏭 Industrial Use:

  • Factories & Warehouses: 200–300 meters with booster support
  • Canteiros de Obras: Rugged models with long-range RF (up to 1 km line-of-sight)
  • Vehicle Yards or Ports: LTE or LoRa-based systems for long-distance communication

    • Boost signal strength and provide coverage through multiple floors or buildings.
  2. Use External Antennas
    • Antennas with higher gain (e.g., 5dBi or 9dBi) can significantly improve RF coverage.
  3. Switch to a Lower Frequency Band
    • Lower frequencies (e.g., 433MHz) penetrate walls better than higher ones like 2.4GHz.
  4. Mesh Network Integration (for WiFi)
    • Create a mesh network to ensure seamless communication across large areas.
  5. Optimize Device Placement
    • Avoid installing units near thick walls, elevators, metal doors, or electrical panels.
  6. Use LTE/4G for Remote Applications
    • For off-grid or wide-area use, cellular modules offer unlimited geographic range.
