 ### Wi-Fi example
 
-Here is an example of an HTTP client program. The program brings up an ESP8266 as the underlying network interface, and uses it to perform an HTTP transaction over a TCPSocket. There are multiple [Wi-Fi components](https://os.mbed.com/components/cat/wifi/) that implement the WiFiInterface class. The example below uses the [ESP8266Interface](https://github.com/armmbed/esp8266-driver) and [OdinWiFiInterface](https://github.com/u-blox/ublox-odin-w2-drivers-docs-mbed-5).

 The ESP8266Interface uses AT commands over serial interface to connect to an external Wi-Fi device. The OdinWiFiInterface provides an Ethernet-like driver to the Mbed OS network stack. The network stack uses the driver to connect to Wi-Fi:
