== 6. Site survey ==
Becuase of the various reaons, on Dec. 16 2010, we decide to change the outdoor and indoor sites to the southwest corner of Mudd building, 14 fl, rooftop.

=== New outdoor site at Mudd 14th floor ===

=== New Indoor site at Mudd 14th floor (neer outdoor site, same level) ===
|| [[ThumbImage(rack_space.jpg, thumb=200)]] ||
 - Need to check the space availabilitye: 5U + pwr suplies.

See [wiki:WIMXCOLUM/CUWIMAX/OldSites "Old outdoor/indoor sites"].

== 7. Indoor installment ==
=== Notes ===
 * It is strongly required connecting with `serial cable' between IDU and ASN-GW server because of monitoring purpose.

== 8. Client Setting ==
 - Platform: Dell Latitude D830 (IRT0045)
 - NIC: Intel Centrino Advanced-N WiMAX 6250 - Mini-PCI express with half size slot (Note: It fails booting on Thinkpad laptops because of their BIOS allows authorized interfaces only. See [http://www.thinkwiki.org/wiki/Problem_with_unauthorized_MiniPCI_network_card] for more details.)
 - OS: Ubuntu 10.10 Maverick with patched linux kernel 2.7.36-rc3
=== NIC installation ===
See [wiki:WIMXCOLUM/CUWIMAX/NicInstall "network interface card installation"] for more detail.
=== Software installation ===
 - Required software (from http://linuxwimax.org)
   1. NIC firmware: i2400m-fw-1.5.0
   1. Driver:compiled and built by patched linux kernel
   1. WiMAX tool: wimax-tools-1.4.4
   1. Open source supplicant: wpa_supplicant-0.7.2 with patch to build libeap.so library
