Method and portable device for determining the stability of radio communications in a wireless lans

摘要

The invention provides a method of determining the stability of a signal parameter (such as throughput) in data transmitted in a wireless LAN. A plurality of values of the parameter are detected over a predetermined time and an average value calculated. The difference between the average value and each of the plurality of values is then determined. The modulus values of the differences are summed and divided by the number in the plurality to obtain a figure representative of stability.
