CONSTANTS

|---|---|---|---|
| MAX_HISTOGRAMS_PER_TYPE |
8
|
uint8 |
For each histogram type (e.g. RSSI), there can be multiple histograms up to this limit. For example, an interface might have 1 histogram for station-wide RSSI, but also 1 for each of the antennas used by the interface. |
| MAX_NOISE_FLOOR_SAMPLES |
255
|
uint8 |
All histograms have a fixed number of buckets. To save space, each histogram type uses a vector to hold only non-empty buckets (a sparse histogram), with these constants as the max size of each vector. Noise floor values range from -255 to -1 dBm. |
| MAX_RSSI_SAMPLES |
255
|
uint8 |
RSSI values range from -255 to -1 dBm. |
| MAX_RX_RATE_INDEX_SAMPLES |

|
uint8 |
Size of RxRateIndexHistogram lookup table (see comments in RxRateIndexHistogram). |
| MAX_SNR_SAMPLES |
