Communication

The Dash7 communication protocol was developed and designed for smart parking: information is retrieved and is instantly sent to the cloud and display systems. Display signs are immediately updated when a vehicle arrives or leaves a car space.
This unique protocol offers unlimited remote access to sensors’ configuration data which can be modified remotely at any time. Maintenance is simplified and updates can be managed remotely to offer always-on, high-performance systems.

To support deployment in existing large-scale network configurations, our oS300 on-street parking sensors are Dash7 and LoRa-compatible. The LoRaWAN network - which is offered by telecom operators - is a IoT network used to connect a wide range of connected objects across France.
Using a LoRaWAN network removes the need for customers to build a dedicated radio network. However, let’s keep in mind that this network was not designed for smart parking and has a number of inconveniences such as high latency and reduced bi-directional transmission.

DASH 7

  • Frequency: 868 MHz
  • Latency: less than 1 second
  • Number of messages: several per minute
  • Bi-directional transmission: high free bandwidth
  • Distance: > 250 m

LoRA

  • Frequency: 868 MHz
  • Latency: several minutes
  • Number of messages: available but expensive and limited
  • Distance: > 2 km

oS Connect radio hub

The oS Connect Hub for optimized data collection

Use data in real time via the oS Connect hub.

The oS Connect radio hub is a core element of our peer-to-peer architecture. The hub collects data from the Onesitu sensors and transfers it to the monitoring platform in real time and then to the various dynamic directional signage available.

It is equipped with a Linux mini-laptop, a 868 MHz radio communication card and a 3G module. For optimized performance, it is based on M2M (Machine-to-Machine) technology.
