Dedicated infrastructure for wireless battery-powered smart meters involves a costly setup. To reduce the cost, one often made compromise is the link reliability, where a majority of packets are allowed to be in error, as long as a few packets are received over a long time frame. On the other hand, each meter transmits frequently to accommodate for drive-by/walk-by remote reading applications, leaving redundancy in the transmissions seen on a dedicated receiver. We utilize the redundancy and the inherent timing structure of the protocol in order to recover metering data from multiple erroneous packet receptions. From an actual deployment a receiver sensitivity gain is found to be around 1dB, equivalent to increasing the number of read meters by 14% in an experiment over 66 hours.
