Thank you for your post Freddy.
Note that since these wireless adapters should be installed by the laptop manufacturer only, there is no integration support or documentation publicly available.
The only two Intel® wireless adapters designed for the end user install are:
Intel® Centrino® Advanced-N 6205 for Desktop (part no: 62205ANHMWDTX1):
Intel® Centrino® Advanced-N 2200 for Desktop (part no: 2200BNHMWDTX1):
Both of the above mentioned are PCIe x1 based, and already include the antennas.
I hope this helps.
