HARDWARE AND SOFTWARE COMPONENTS
This chapter describes the components and procedures for building a wireless application
with a Linux host and Telit WE866C3 Wi-Fi NIC module.
The Telit WE866C3 module provides IEEE802.11a/b/g/n/ac Wireless LAN functionalities.
It integrates complete MAC, PHY and RF functionality on a single chip providing a low
cost and an easy-to-use solution for adding wireless connectivity to applications.
WE866C3 modules integrate the required components like crystals, regulators, RF front
end components to provide ready-to-use WLAN radio modules that can be used as NIC
cards to provide network connectivity to hosts. These modules are regulatory, certified
and calibrated for easy integration and building applications instantly without requiring any
work on radio connectivity modules.
WE866C3 modules provide an external interface, i.e., SDIO port to interface it to a variety
of hosts. The SDIO interface provides Ultra High Speed (SDR104) interconnection for
faster communication with the host systems that are based on processors with 32-bit CPU
and MMU which run on Linux operating systems. The Linux host runs the WLAN drivers,
the network stack, the supplicant and authenticator 802.11 security applications to
establish an 802.11 based Wireless LAN network using the WE866C3 module.
Standard Linux applications such as
“wpa_supplicant” and “hostapd” are used for control
path communications and standard Linux data path is used for data communications, and
no custom software required.
