OMS® v4.5.1 + LoRaWAN® v1.0.4 + OMS® over LoRaWAN® 

Triple Stack 

Triple Stack: OMS v4.5.1 & LoRaWAN v.1.0.4 & OMS over LoRaWAN

Key Features

Integration

Combination of OMS® interoperability 
with long range of LoRaWAN®

Scalability

Remote meter reading enabled
by fixed networks and drive-by / walk-by

Backup-solution

Backup solution: communication via 
OMS® / wM-Bus if fixed network
has no connection

seamless switching between stacks

Switching of stacks "on-the-fly" and during compile time

Your benefits with our stack package

Stack Package Architecture

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
