Data Compaction Techniques
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.
