OMS® v4.5.1 + LoRaWAN® v1.0.4 + OMS® over LoRaWAN®
Triple Stack
Key Features
Combination of OMS® interoperability
with long range of LoRaWAN®
Remote meter reading enabled
by fixed networks and drive-by / walk-by
Backup solution: communication via
OMS® / wM-Bus if fixed network
has no connection
Switching of stacks "on-the-fly" and during compile time
Your benefits with our stack package
On-the-fly configuration
Quick stack adaption to different use cases
Platform Interface now available as source code
- Customization and fine tuning of platform driver
- Customization of radio settings (e.g., frequency)
User-defined protocol priority
To be set for each possible state of a system
OPTIMIZED FOOTPRINT
When using a dual stack compared to using two single stacks, the memory requirement is significantly optimized.
Strengthen the future viability of your devices with this stack
