6. Indoor installment
Notes
- It is strongly required connecting with `serial cable' between IDU and ASN-GW server because of monitoring purpose.
7. 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 network interface card installation for more detail.
Software installation
- Required software (from http://linuxwimax.org)
- NIC firmware: i2400m-fw-1.5.0
- Driver:compiled and built by patched linux kernel
- WiMAX tool: wimax-tools-1.4.4
- Open source supplicant: wpa_supplicant-0.7.2 with patch to build libeap.so library
- WiMAX network service: wimax-1.5.1, Intel's WiMAX daemon
