(Not recommended.)ĪES: Advanced Encryption Standard, also called Counter Mode with CBC-MAC Protocol (CCMP). This encryption protocol is still based on RC4 but some improvements were made, such as adding message integrity check (MIC). There are two key lengths, 64-bit and 128-bit. This is the first Wi-Fi encryption algorithm, based on RC4. The actual protocol is 802.11i, as indicated in the comments above. (Wi-Fi Protected Access®, WPA™, and WPA2™ are trademarks for certification programs of Wi-Fi Alliance. WPA2-EAP: Same as WPA-EAP but for WPA version 2 (802.11i). WPA2-PSK: Same as WPA-PSK but for WPA version 2 (802.11i) Uses the authenticated key mode that derives keys from 802.1X. Based on 802.11i pre-shared key authentication. This is a working standard put together by the Wi-Fi Alliance. Shared Key: An old Authentication type, only used with WEP. Any Wi-Fi stations can connect to each other. Open System: There is no special authentication. One is the Authentication Type and the other is the Encryption Algorithm/Protocol. Wi-Fi Simple Configuration simplifies connection to an AP or other device. When used with SoftAP, it allows the device to be the Group Owner, else only a client. As with any Wi-Fi device, the range is up to 200m, making connection convenient even when devices are not in immediate proximity to one another. Improvements over ad-hoc include easier connection and the latest security, 802.11i. It is a protocol designed to replace the legacy ad-hoc (IBSS) protocol. Wi-Fi Peer-to-Peer (P2P) allows easy, direct connection among Wi-Fi devices, anywhere. SoftAP provides simple Access Point functionality to allow connection of Wi-Fi devices. This is documented in detail in the manual. To support USB dongles, a USB host stack is required, such as smxUSBH (strongly recommended).įor dynamic rate switching, smxWiFi has substantial logic to adjust the transmit rate according to the packet error ratio. A TCP/IP stack is also required, and smxWiFi has been integrated with smxNS. Porting Layer Provides service functions related to the hardware, OS, and compiler.ĭue to the complexities of the 802.11 protocol, smxWiFi requires a multitasking RTOS environment.

Chipset Driver Layer Provides a unique interface for different Wi-Fi MAC and RF chipsets such as the Ralink RT3572.MLME Layer Provides services for the MAC Layer Management Entity, such as scan, authentication,.Application Interface Layer Provides the interface to the application to manage the networking connection, retrieve the signal and link quality information, and do a site survey.Network Interface Layer Provides the interface to a TCP/IP stack.Learn how protocols supported by smxWiFi correspond to the certification programs of Wi-Fi Alliance, such as Wi-Fi Direct™, Wi-Fi Protected Setup™, Wi-Fi Protected Access®, WPA™, and WPA2™. New: 802.11ac, Dynamic Rate Switching (DRS), and MT7612 driver.

smxWiFi provides the necessary software to add wireless connectivity to an embedded system.
While optimized for SMX®, smxWiFi can be ported to another RTOS or to another hardware platform to support a different Wi-Fi chipset.Īn 802.11 network is a wireless local area network (WLAN) that conforms to the 802.11 standards.
It is written in C, and can run on any hardware platform. SmxWiFi is a robust 802.11 Media Access Control (MAC) stack specifically designed and developed for embedded systems.
