In this paper, we present some results of long-term measurement in the 433 MHz, wireless telemetric network dedicated to watt-hour meter reading. The RSSI of received packets was measured by the sink. The sink was equipped with a half wave, 4 dBi antenna. Received and recorded data enabled us to make analysis of PER versus RSSI from all nodes within range of the sink, simultaneously. With knowledge of how many packets sink expected to receive, during the query and how long frames were, we propose the designation of the value of FER estimator. Lack of relationship between FER and frame length prompted us to investigate errors at bits level. Both the sink and other nodes were equipped with CC1101 low power RF transceiver. The paper concludes with the areas of the results application.
