Data Compaction Techniques

Abstract

Many areas of technology need highly accurate data compression to provide small, multifunctional devices. For example, 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.

1 . A method of providing a compressed conformance testing limit (CTL), the method comprising:
 representing each band of a regulatory domain as a pair of band edges;   designating in-band frequencies within each band; and   providing at least two non-overlapping regulatory domains in the CTL.   
     
     
         2 . The method of  claim 1 , wherein designating an in-band frequency includes providing a non-edge flag value different than that for a band edge. 
     
     
         3 . The method of  claim 1 , further including providing at least two completely overlapping regulatory domains in the CTL. 
     
     
         4 . A storage device readable by a driver, the storage device storing data representing a conformance testing limit (CTL), the data being compressed using a method comprising:
 representing each band of a regulatory domain as a pair of band edges;   designating in-band frequencies within each band; and   providing at least two non-overlapping regulatory domains in the CTL.   
     
     
         5 . The storage device of  claim 4 , wherein the method further includes providing at least two completely overlapping regulatory domains in the CTL. 
     
     
         6 . A computer program product comprising:
 a computer usable medium having a computer readable program code embodied therein for causing a computer to compress conformance testing limit (CTL) data for a wireless device, the computer readable program code comprising:   computer readable program code that represents each band of a regulatory domain as a pair of band edges;   computer readable program code that designates in-band frequencies within each band; and   computer readable program code that provides at least two non-overlapping regulatory domains in the CTL.   
     
     
         7 . The computer program product of  claim 6 , further including computer readable program code that provides at least two completely overlapping regulatory domains in the CTL. 
     
     
         8 . A system for compressing conformance testing limit (CTL) data for a wireless device, the system comprising:
 means for representing each band of a regulatory domain as a pair of band edges;   means for designating in-band frequencies within each band; and   means for providing at least two non-overlapping regulatory domains in the CTL.   
     
     
         9 . A storage device readable by a driver, the storage device storing data representing a conformance testing limit (CTL), the data comprising:
 at least two non-overlapping regulatory domains in the CTL, wherein each band of a regulatory domain is represented as a pair of band edges, and wherein in-band frequencies are designated within each band.   
     
     
         10 . The storage device of  claim 9 , further including at least two completely overlapping regulatory domains in the data.
