ESP8266 wifi module will be the highly recommended for Internet Of Things (IoT). The ESP8266 series, or family, of Wi-Fi chips is produced by Espressif Systems, a fabless semiconductor company.
Board comes with preloaded bootloader hence you don’t need any external programmers . It has numerous on-board peripherals to interface them with the main controller. All the peripherals connections are broken out. A unique feature of the kit is that, oneMicro base board supports various 8 bit, 16 bit and 32 bit microcontroller breakout boards.
- 802.11 b/g/n/e/i support.
- Wi-Fi Direct (P2P) support.
- P2P Discovery, P2P GO (Group Owner) mode, GC(Group Client) mode and P2P Power Management.
- Infrastructure BSS Station mode / P2P mode / SoftAP mode support.
- Hardware accelerators for CCMP (CBC-MAC, counter mode), TKIP (MIC, RC4), WAPI
- (SMS4), WEP (RC4), CRC.
- WPA/WPA2 PSK, and WPS driver.
- Additional 802.11i security features such as pre-authentication, and TSN.
- Open Interface for various upper layer authentication schemes over EAP such as TLS, PEAP, LEAP, SIM, AKA, or customer specific.
- 802.11n support (2.4 GHz).
- Supports MIMO 1×1 and 2×1, STBC, A-MPDU and A-MSDU frame aggregation and 0.4μs guard interval.
- WMM power low U-APSD.
- Multiple queue management to fully utilize traffic prioritization defined by 802.11e standard.
- UMA compliant and certified.
- 802.1h/RFC1042 frame encapsulation.
- Scattered DMA for optimal CPU off load on Zero Copy data transfer operations.
- Antenna diversity and selection (software managed hardware).
- Clock/power gating combined with 802.11-compliant power management dynamically adapted to current connection condition providing minimal power consumption.
- Adaptive rate fallback algorithm sets the optimum transmission rate and Tx power based on actual SNR and packet loss information.
- Automatic retransmission and response on MAC to avoid packet discarding on slow host environment.
