1 Introduction 83
84
Today, all operators offering roaming have implemented Passive Roaming with Activation 85
Away feature (see Backend Interfaces Specification [TS2]). 86
87
To optimize the QoS of Passive Roaming on the LoRaWAN Network, it is necessary to define 88
and share a few technical requirements between operators. 89

Figure 1: Global Architecture for Roaming Between Operators 93
94
Figure 1 illustrates the architecture between two public LoRaWAN operators. 95
96
The regional parameters depend on the country and regulations ([RP]). In each country, each 97
public operator has its own radio frequency plan. 98
99
The challenge is that when the device moves to a different operator's coverage, it changes 100
the operator; however, the device does not recognize this change and continues to use the 101
previous radio parameters (frequency plan, etc.). 102
103
It is necessary to share the information described in this document with network operators to 104
optimize the QoS and improve network resources of the device. 105
