Table 2.

SWOT analysis of CSI-based fingerprinting applied for indoor positioning systems.

Strengths Weakness Opportunity Threats
  • -

    Enhanced wireless channel metric

  • -

    Relatively stable in complex indoor environment

  • -

    Rich in signal information/features
  • -

    Requires extra investment

  • -

    Implementation is not easy
  • -

    Significant applications demand high positioning accuracy

  • -

    Need for high dimension of signal features
  • -

    Appropriate signal processing technology is required

  • -

    Inherent heterogenous environment settings

  • -

    Duplication of fingerprints due to signal modulation on multiple channels
