  • 2.4 GHz band: +21 dBm (18 dBm per chain)
  • 5 GHz band: +21 dBm (18 dBm per chain)
• Advanced Cellular Coexistence (ACC) minimizes interference from cellular networks
• Maximum ratio combining (MRC) for improved receiver performance
• Cyclic delay/shift diversity (CDD/CSD) for improved downlink RF performance
• Short guard interval for 20-MHz, 40-MHz and 80-MHz channels
• Space-time block coding (STBC) for increased range and improved reception
