LoRaWAN

LoRaWAN is a highly reliable standard for wireless low-power private networks in the unlicensed 868 MHz band. It allows transmitting small amounts of data at a distance of up to 15 km in the line of sight and 1.5-2 km in densely built-up urban areas.

The network topology

is a classic star with the centre at the base station. Within the same LoRaWAN network, there may be several base stations with a single network server that provides optimal communication with subscribers and load balancing in the network.

LoRaWAN

Advantages

No licensing requiredThe two-way encrypted communication channel
Open standard, availability of open source hardware and software, independence from a specific manufacturer or telecom operatorThe capability to deploy both your own private network and use of existing LoRaWAN networks
A network scalability to several hundred thousand devices by installing new base stations

LoRaWAN

Features

  • The communication channel is asymmetric; the bandwidth from the devices to the base station is several times wider than in the opposite direction
  • The channel is focused on the proactive data transmission

The implementation of LoRaWAN technology in Mercury meters provides both proactive data transmission when an event occurs or according to a schedule, for example, the readings transmission at the beginning of the day or alarming events when a meter cover is opened and also their operation in the AMR/AMI ‘request-response’ mode.
