Description
The nanoBTS has the capability to OCXO calibration against another (macro) BTS. We had implemented this in ipaccess-config, but we apparently never documented how it works.
Let's add it somewhere to the nanoBTS related wiki pages.
Without trying, I remember that it was part of the "Tests" that can be triggered via OML.
static const struct value_string test_names[] = { »·······{ NM_IPACC_TESTNO_CHAN_USAGE, "Channel Usage" }, »·······{ NM_IPACC_TESTNO_BCCH_CHAN_USAGE, "BCCH Channel Usage" }, »·······{ NM_IPACC_TESTNO_FREQ_SYNC, "Frequency Synchronization" }, »·······{ NM_IPACC_TESTNO_BCCH_INFO, "BCCH Info" }, »·······{ NM_IPACC_TESTNO_TX_BEACON, "Transmit Beacon" }, »·······{ NM_IPACC_TESTNO_SYSINFO_MONITOR, "System Info Monitor" }, »·······{ NM_IPACC_TESTNO_BCCCH_MONITOR, "BCCH Monitor" },
I think you start with a CHAN_USAGE to see the receive level per ARFCN. You then proceed to a FREQ_SYNC to see which of those have a FCCH (and hence are BCCH/CCCH carrying).
