6 Detailed Description
6.1 Overview
The CC3120MOD Wi-Fi module contains a dedicated ARM MCU that offloads many of the networking
activities from the host MCU. Including an 802.11 b/g/n radio, baseband, and MAC with a powerful crypto
engine for a fast, secure WLAN and Internet connections with 256-bit encryption. The CC3120MOD
module supports station, AP, and Wi-Fi Direct modes. The module also supports WPA2 personal and
enterprise security and WPS 2.0. The Wi-Fi network processor includes an embedded IPv6 and IPv4
TPC/IP stack.
6.2 Module Features
6.2.1 WLAN
The WLAN features are as follows:
• 802.11 b/g/n integrated radio, modem, and MAC supporting WLAN communication as a BSS station,
AP, and Wi-Fi Direct client and group owner with CCK and OFDM rates in the 2.4-GHz ISM band,
channels 1 to 13.
NOTE
802.11n is supported only in Wi-Fi station, Wi-Fi direct, and P2P client modes.
• Autocalibrated radio with a single-ended 50-Ω interface enables easy connection to the antenna
without requiring expertise in radio circuit design.
• Advanced connection manager with multiple user-configurable profiles stored in a serial flash allows
automatic, fast connection to an access point without user or host intervention.
• Supports all common Wi-Fi security modes for personal and enterprise networks, with on-chip security
accelerators, including WEP, WPA/WPA2 PSK, and WPA2 Enterprise (802.1x).
• Smart provisioning options deeply integrated within the device provide a comprehensive end-to-end
solution. Elaborate events notification to the host enable the application to control the provisioning
decision flow. The wide variety of Wi-Fi provisioning methods include:
– Access Point using HTTPS
– SmartConfig Technology: a 1-step, 1-time process to connect a CC3120MOD-enabled device to the
home wireless network, removing dependency on the I/O capabilities of the host MCU; thus, the
device is usable by deeply embedded applications.
• 802.11 transceiver mode transmits and receives proprietary data through a socket without adding MAC
or PHY headers, and provides the option to select the working channel, rate, and transmitted power.
The receiver mode works together with the filtering options.
