0~Mishra, Partho~parthomishra@woodsidenet.com~650 475 1983~~Woodside Networks~09~9.1~34~20-22~TR~While there is an extensive treatment of the calculation of bit error rate from SINR, the performance results shown in clause 9 show packet error rate. There is a dubious statement that 'the packet error rate for the WLAN corresponds to the loss of ACK messages'. In reality the packet error rate will be dominated by the loss of data packets, since they tend to be longer than ACK packets and hence more vulnerable to bit errors. This would yield more pessimistic results then those shown. On the other hand there is no discussion of the correlation of the bit errors. If there is structure in the interference (and in this case there is) then bit errors tend to be correlated. This would yield a packet error rate which is less than that for i.i.d. distributed bit errors, i.e. it would make the results more favorable.  A third effect which aggravates the packet error rate is the effect of interference on packet detection, which is not modeled and which tends to dominate the probability of packet loss by decoding errors, especially at low SINRs.~Specify the model for translating bit errors to packet errors and add a discussion of contributing factors to packet loss which have not been modeled.~~X~O
