SWAS034 – FEBRUARY 2017
5.3 Device Features
5.3.1 WLAN
The WLAN features are as follows:
• 802.11b/g/n integrated radio, modem, and MAC supporting WLAN communication as a BSS station,
AP, 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 mode
• 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 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).
• Smart provisioning options deeply integrated within the device providing a comprehensive end-to-end
solution. With elaborate events notification to the host, enabling 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 CC3120R-enabled device to the
home wireless network, removing dependency on the I/O capabilities of the host MCU; thus, it is
usable by deeply embedded applications
• 802.11 transceiver mode allows transmitting and receiving of proprietary data through a socket without
adding MAC or PHY headers. The 802.11 transceiver mode provides the option to select the working
channel, rate, and transmitted power. The receiver mode works with the filtering options.
5.3.2 Network Stack
The Network Stack features are as follows:
• Integrated IPv4, IPv6 TCP/IP stack with BSD (BSD adjacent) socket APIs for simple Internet
connectivity with any MCU, microprocessor, or ASIC
NOTE
Not all APIs are 100% BSD compliant. Not all BSD APIs are supported.
• Support of 16 simultaneous TCP, UDP, or RAW sockets
• Support of 6 simultaneous SSL\TLS sockets
• Built-in network protocols:
– Static IP, LLA, DHCPv4, DHCPv6 with DAD and stateless autoconfiguration
– ARP, ICMPv4, IGMP, ICMPv6, MLD, ND
– DNS client for easy connection to the local network and the Internet
