Wi-Fi connectivity

The ESP8266 has a Radio Frequency (RF) transceiver with the following modules:

• 2.4 GHz transmitter and receiver

• Power management

• Real-time clock

• High-speed crystal oscillator and clock generator

• Regulators and bias

The RF transceiver supports 14 channels within the 2.4 GHz band in accordance to the IEEE802.11bgn standard. The channels range from 2.412 to 2.484 GHz. The RF receiver employs the use of Automatic Gain Control (AGC) integrated RF filters and DC offset compensation to accommodate the different signal channels.

A high-power CMOS amplifier drives the antenna. This enables the RF transmitter to achieve an average...
