During the offline phase, 10 sample vectors collected atlocationsL1-L9 of the three floors.
The value of offline vector for each location is determined by averaging the 10 sample vectors.
The resulting averaged fingerprint vectors for each of the nine locations are then tabulated in an offline database system. Table 1 shows an example of fingerprint vector database tabulated during offline phase.
All the RSS values are measured in dBm over time.
