Performance testing

  • 1 STA and 1 AP connected to the Internet
  • The performance impact is not critical.
  • Users of the network had no suspicion.
  • 8 STAs and 1 AP connected to the Internet
  • The performance impact is more severe.
  • Despite the performance impact, users had no

suspicion.
