Stationary collectors reading wireless, battery powered smart meters, often operate in harsh channel conditions to cut network installation cost to a minimum, challenging the individual link to each meter. The desired performance measure is reliable reception of at least some data from as many as possible meters, rather than increasing the fraction of received packets from one meter. As a first step for improving reliable reception, and motivated by the recent revision of Wireless M-Bus, the authors propose the use of a deterministic packet transmission interval to group packets from the same meter.
