|

|
|
|
|
+Intel wireless LAN adapters are engineered, manufactured, tested, and
|
|
|
|
+quality checked to ensure that they meet all necessary local and
|
|
|
|
+governmental regulatory agency requirements for the regions that they
|
|
|
|
+are designated and/or marked to ship into. Since wireless LANs are
|
|
|
|
+generally unlicensed devices that share spectrum with radars,
|
|
|
|
+satellites, and other licensed and unlicensed devices, it is sometimes
|
|
|
|
+necessary to dynamically detect, avoid, and limit usage to avoid
|
|
|
|
+interference with these devices. In many instances Intel is required to
|
|
|
|
+provide test data to prove regional and local compliance to regional and
|
|
|
|
+governmental regulations before certification or approval to use the
|
|
|
|
+product is granted. Intel's wireless LAN's EEPROM, firmware, and
|
|
|
|
+software driver are designed to carefully control parameters that affect
|
|
|
|
+radio operation and to ensure electromagnetic compliance (EMC). These
|
|
|
|
+parameters include, without limitation, RF power, spectrum usage,
|
|
|
|
+channel scanning, and human exposure.
|
|
|
|
+
|
|
|
|
+For these reasons Intel cannot permit any manipulation by third parties
|
|
|
|
+of the software provided in binary format with the wireless WLAN
|
|
|
|
+adapters (e.g., the EEPROM and firmware). Furthermore, if you use any
|
|
|
|
+patches, utilities, or code with the Intel wireless LAN adapters that
|
|
|
|
+have been manipulated by an unauthorized party (i.e., patches,
|
|
|
|
+utilities, or code (including open source code modifications) which have
|
|
|
|
+not been validated by Intel), (i) you will be solely responsible for
|
|
|
|
+ensuring the regulatory compliance of the products, (ii) Intel will bear
|
|
|
|
+no liability, under any theory of liability for any issues associated
|
|
|
|
+with the modified products, including without limitation, claims under
|
|
|
|
+the warranty and/or issues arising from regulatory non-compliance, and
|
|
|
|
+(iii) Intel will not provide or be required to assist in providing
|
|
|
|
+support to any third parties for such modified products.
|
|
|
|
+
|
|
|
|
+Note: Many regulatory agencies consider Wireless LAN adapters to be
|
|
|
|
+modules, and accordingly, condition system-level regulatory approval
|
|
|
|
+upon receipt and review of test data documenting that the antennas and
|
|
|
|
+system configuration do not cause the EMC and radio operation to be
|
|
|
|
+non-compliant.
|
|
|
|
+
|
|
|
|
+The drivers available for download from SourceForge are provided as a
|
|
|
|
+part of a development project. Conformance to local regulatory
|
|
|
|
+requirements is the responsibility of the individual developer. As
|
|
|
|
+such, if you are interested in deploying or shipping a driver as part of
|
|
|
|
+solution intended to be used for purposes other than development, please
