I received an error message when performing Calibration model to add data points in WCS.
MAC is not detected as a client but found on floor.
Upon reading over the RF calibration, it was noted that Cisco recommends using the Cisco Aironet 802.11 a/b/g Wireless cardbus Adapter Client (AIR-CB21AG) with recent drivers and firmware (CCX version 2 or better) as a calibration data collection client. Versions of CCX earlier than version 2 are not ideal for calibration usage.
Does that mean, I must use a CCXv2 WiFi card to perform the RF calibration?
It means that the system works better with CCXv2 and later clients when performing a calibration. I used Cisco Card, Intel internal, RFID Tag, and Proxim Card. This assures a good overall calibration. I try to calibrate for multiple devices because the methodology of location services is RF Fingerprinting based on received RSSI values and those can differ between clients.
