Abstract:
1. A method of dynamically adapting wireless link parameters, comprising: determining a measure of errors occurring in communication over a wireless link; in a case that the measure of errors corresponds to more errors than a first predetermined threshold, changing from a first set of wireless link parameters to a second set of wireless link parameters, the second set of wireless link parameters corresponding higher error tolerance than the first set of wireless link parameters; and in a case that the measure of errors corresponds to fewer errors than a second predetermined threshold, changing from the first set of wireless link parameters to a third set of wireless link parameters, the third set of wireless link parameters corresponding to lower error tolerance than the first set of wireless link parameters; wherein: each set of wireless link parameters corresponds to a relationship between throughput efficiency and error rate; the first predetermined threshold corresponds to intersection of the relationship for the first set of wireless link parameters with the relationship for the second set of wireless link parameters; and the second predetermined threshold corresponds to intersection of the relationship for the first set of wireless link parameters with the relationship for the third set of wireless link parameters.
