2. Wi-Fi protocol
•Support 802.11 b/g/n/e/i.
•Support Wi-Fi Direct (P2P).
•P2P found that P2P GO mode (Group Owner), GC mode (Group Client) and P2P power
management.
•Infrastructure BSS workstation mode/P2P mode/SoftAP mode.
•Support CCMP (CBC-MAC, counter mode), TKIP (MIC, RC4), WAPI (SMS4), WEP (RC4), CRC
hardware accelerator.
• WPA/PA2 PSK and WPS.
• 802.11i security features: pre-authentication and TSN.
•Open interfaces for enterprise platforms, such as TLS, PEAP, LEAP, SIM, AKA or custom
interfaces.
•Support 802.11n (2.4 GHz).
•Support MIMO 1*1 and 2*1, STBC, A-MPDU and A-MSDU frame aggregation technology, 0.4
us protection interval.
• WMM low power U-APSD.
•Multi-queue management, making full use of 802.11e standard's QoS transmission priority.
• UMA certification standards.
• 802.1h/RFC1042 Frame Package。
• Decentralized DMA, Zero Copy for data transmission operation, optimize CPU load.
• Antenna diversity and selection (software control hardware).
•Clock/power gating dynamically adapts to current connection conditions and achieves
minimum power consumption along with power management conforming to 802.11
standard.
•Adaptive rate regression algorithm controls the optimal transmission rate and transmission
power consumption based on actual signal-to-noise ratio (SNR) and packet loss information.
•Automatic retransmissions and replies at the MAC layer to prevent data packets from being
discarded in slow host environments.
•Seamless roaming support.
