iMETOS® NB IoT
LPWAN DATA LOGGER FOR URBAN AREAS.
iMETOS® NB IoT is a new generation of the iMETOS® weather stations, that operates on the NB IoT network.
Mounting in the field is done in minutes. iMETOS® NB IoT can handle various sensors. Data is permanently measured in 5-minute interval and sent every 15 minutes to the server. All the data is synchronized with FieldClimate.
iMETOS® NBIoT weather station uses the NBIoT frequency for data transmission. The device requires the provisioned SIM card and needs to be in range of the NBIoT network.
Data transmission is made from the iMETOS® NBIoT weather station directly to the Pessl Instruments system using the UDP protocol.
The client has to set two things so the station can communicate:
- MCC and MNC of the SIM card network provider
- APN name (if used by the NBIoT network provider)
Optional settings (usually the default values are already set and work fine):
- IP address and port of the Pessl Instruments receiving server
- NBIoT network settings
Currently, we have 2 versions on stock and 1 in development:
NB-IoT is a Low Power Wide Area Network (LPWAN) technology that uses low power for communication and is therefore suited for the IoT connected devices. NB-IoT runs in the mobile network frequency space, using unused GSM channels or free space between LTE channels.
NB-IoT network can be only provided by the mobile network operators and a dedicated regional frequency is needed.
Typical range of the NB-IoT enabled IoT devices is 15 kilometers from the base station.
Useful for smart devices which sends small amount of data and can get also response from the server to the device. Useful for smart sensors, tracking and fleet management (coverage should be the same as for the GSM signal after all frequencies and licenses in each country are covered).
Each IoT device needs to have a provisioned SIM card, provided by the NB-IoT network operator. Latency can be between 1 and 10 seconds, the speed of the network is low and it is intended to transfer only smaller amounts of data (not more than 1 MB).
