and error free transmissions occur on that channel within a predetermined time period t using such data one may define interference in various ways and each is contemplated by the present invention for example if the number of erroneous transmissions exceeds the number of error free transmissions on that channel within the predetermined time period by a predetermined amount e g a threshold amount an interference determination may be made such a determination may be made using a counter for example wherein an identified erroneous transmission causes the counter to be incremented while an error free transmission results in the counter being decremented in such an example after the time period t the counter value may be compared to a predetermined threshold value with the determination of interference based on whether the counter exceeds the threshold alternatively other criteria for interference may be employed and are contemplated by the present invention for example separate counters may be employed to account for erroneous and error free transmissions during a time period t resulting in count values a and b respectively a ratio e g a b may then be calculated and compared to another predetermined threshold for a determination of whether interference exists on the channel the method 10 then proceeds to event 20 wherein an interference analysis is performed on another channel associated with the system in the event that a channel was determined to have interference associated therewith and is.
