Chapter 1 Produktintroduktion
1.1 Product overview
Our self-developed LoRaWAN carbon dioxide three-in-one device has the characteristics of small size and integration. It is convenient to transport, carry and install, and can be adjusted dynamically at any time. The appearance of the equipment, working conditions, safety requirements, functional requirements and communication requirements can all be adapted to different measurement environments.
The device measures data in real time and uses wireless networks for transmission. The product network transmission adopts a stable and reliable operator network with mature technology, stable transmission, strong signal and wide coverage. At the same time, the device supports timing data collection and active upload to the server platform.
1.2 LoRaWAN features
- Transmission distance: up to 1km in towns, up to 3km in open suburbs
- Working frequency: ISM frequency band including 433, 868, 915 MHZ, etc.
- Modulation method: based on spread spectrum technology, a variant of linear modulation spread spectrum (CSS), with forward error correction (FEC) capability, proprietary patented technology of semtech
- Transmission rate: hundreds to tens of Kbps, the lower the rate, the longer the transmission distance.
1.3 LoRaWAN product advantages
- Low cost, wide coverage, low power consumption, long life.
- Consistent, stable and reliable.
- Long transmission distance, strong signal, flexibility in deployment services.
- Battery life and long service life.
- A physical layer modulation technology, which can be used in different protocols.
- Good security and confidentiality.
