Table 3-15. Modem Rate Vs. Buffer Size
• A high number of RADIO NO RX BUFFERS that are relative to the number of the RADIO
ERROR BUFFERS indicates the existence of problems in one or more frequency channels.
• It is recommended to have RADIO BUFFERS ERROR RATE under 2% (2e-2). High error
rate indicates bad reception conditions. High error rate combined with a relatively high
number of not received buffers indicates weak radio signal or existence of an interfering
signal source.
The “Error correction algorithm” graph indicates the expected Bit Error Rate after error
correction of the Wireless Modem versus RADIO BUFFERS ERROR RATE. See the
description of the Error correction algorithm in the Technical Specification.
