1.orthogonal frequency division multiplexing -OFDM
2.direct sequence spread spectrum-DSSS
3.complementary code keying-CCK
Those three technology offers various data rates defined in the IEEE 802.11 b/g/n protocol.
Standard bandwidth :It supports 20 MHz
Narrow bandwidth:5 MHz/10 MHz is supported
Module chipset integrates a high-performance 32-bit microprocessor, a hardware security engine, and various peripheral interfaces, including the SPI, UART, I2C, PWM, GPIO, and multi-channel ADC. In addition, it provides high-speed SDIO2.0 slave interfaces, with clock frequency up to 50 MHz. Its built-in SRAM and flash can operate independently and even programming is allowed on the flash.
