WiFi Card Calibration ¶

As an first and maybe last important discovery in ORBIT testbed, some (if not most) WiFi cards behaved strangely. Therefore, it is really important to identify those bad cards.

Calibration Procedure ¶

1. Pick up one node from the grid and take it down from the shelf
2. load baseline-calibration.ndz image to the node
3. Connecting RF cable to one of the card
4. ssh to console.grid
5. ./caliber.pl [mac-addr]
6. check the calibration_central database in idb1.
7. Do above procedures for another card
