450 Mhz moduler til brug i smart meter applikationer

Rutronik kan nu levere LTEM/NB-IoT moduler fra fra Telit, der opererer i 450MHz frekvensbåndet, hvilket forøger rækkevidden og muliggør brug i selv de mest udfordrende indendørs miljøer (in english).

Interference-free connection to the electricity meter represent a challenge: With cellular standards such as 2G/GSM it is hardly possible to communicate with devices in deep indoor areas.

The new ME310G1-W2 LTEM/NB-IoT module from Telit uses the 450MHz frequency band which overcomes this lack of range. So even the most distant meter in the basement still receives a signal.

Due to the narrow range of previous cellular standards, so far smart meters areusually equipped with a proprietary solution working on the Sub-GHz frequency bands, which transmits the data to a central gateway. The gateway sends then the collected data via GSM or LTE to the cloud. 


LTE-M, NB-IoT as well as the use of the 450 MHz band improve the range significantly and make the need of a gateway obsolete. Data can be send now directly from the meter to the cloud.
The ME310G1-W2 LTE-M/NB-IoT module supports LTE Cat M1 and NB2 in accordance to the 3GPP release 14. It integrates additionally an GNSS receiver. Thanks to the very small form factor of only 15 x 18mm, the module is also ideally suited for smaller designs.
