9 Detailed Description
9.1 Overview
The CC3135MOD dual-band Wi-Fi module contains a dedicated Arm
®
MCU that offloads many of the
networking activities from the host MCU. Including an 802.11 a/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 CC3135MOD
module supports station, AP, and Wi-Fi Direct modes. The device also supports WPA2 personal and enterprise
security, WPS 2.0, and WPA3 personal and enterprise security
. The Wi-Fi network processor includes an
embedded IPv6 and IPv4 TPC/IP stack.
9.2 Module Features
9.2.1 WLAN
The WLAN features are as follows:
• 802.11 a/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, and 5 GHz U-NII band.
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, WPA2 Enterprise (802.1x), WPA3 Personal and WPA3
Enterprise.
• 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 CC3135MOD-enabled module 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.
