ADEUNIS RF - WMBUS GPRS GATEWAY USER GUIDE V2.5.110Page of 192.3.3 Autonomy tableDepending on WMBUS listening cycles and the number of GPRS, the autonomy of self-powered versions of the AMR gateway mayvary.

A received frame will bestored only once during this period. This mechanism avoids the memory to be overloaded by products emitting very often. |
