Abstract

Many areas of technology need highly accurate data compression to provide small, multifunctional devices. In the area of communication governed by the IEEE 802.11 standards, a wireless device could significantly improve its performance by using its calibration data. Moreover, because of the increased mobility of users, a wireless device should be able to operate in different regulatory domains. This flexibility requires access to significant amounts of data regarding such regulatory domains. Advantageously, piecewise linear abstraction and/or mapping can be used to significantly reduce the amount of stored data while ensuring accuracy in reproducing the total data at a later point in time.
