Connect One recently launched Nano WiReach embedded WiFi bridge. The Nano WiReach quickly and easily connects any embedded device to 802.11b/g wireless LANs with minimal programming. Measuring only 1.7×3.3 centimeters, the Nano WiReach’s multiple hardware interfaces and extensive firmware functionality make it the most advanced and versatile WiFi solution for embedded devices today. Nano WiReach includes a full suite of Internet protocols and applications, enabling immediate and full featured connectivity for embedded solutions without any WiFi driver development or porting. Pricing starts at $59.
Nano WiReach Modes of Operation
- LAN to WiFi Bridge
Allows transparent bridging of LAN over WiFi using direct RMII connection to existing MAC hardware. Any microcontroller with a built-in Ethernet MAC can be connected to WiFi with zero development effort
- Serial to WiFi Bridge
Enables transparent bridging of serial data over WiFi using the module’s speedy 3-Mbps UART
- Full Internet Controller mode
Allows simple microcontrollers to use the Nano WiReach’s rich protocol and application capabilities to perform complex Internet operations such as e-mail, FTP, SSL, embedded web server and others. Internet controller mode can be used with any hardware interface
- Embedded IP Routing
Allows multiple WiFi clients to user a single WAN connection to the Internet, using the Nano WiReach as a router
- PPP emulation
Offers existing (e.g., cellular modem) designs currently using PPP to interface to the cellular modem by connecting transparently over WiFi with no changes to application or drivers
Nano WiReach includes RMII, USB, SPI and fast UART interfaces for easy integration into existing or new designs. It is available in two versions — one with an antenna connector and one with a built-in antenna. Nano WiReach offers a highly advanced level of Internet security. It includes the latest WiFi encryption algorithms (WPA/WPA2, in both PSK and enterprise modes) and Internet SSL encryption algorithms. In addition, it serves as an inherent firewall, protecting the embedded application from attacks originating from the Internet.
Nano WiReach effectively and quickly WiFi-enables devices that use any kind of embedded real-time operating system. Designers do not need to port/write WiFi drivers or significantly reprogram their applications to connect to WiFi using the Nano WiReach. In Internet Controller mode, Nano WiReach is driven by simple text commands and offloads the WiFi drivers, WPA supplicant, Internet security, networking protocols, and all communication tasks from the host microcontroller and application. This offloading of communication tasks frees up host processing bandwidth and simplifies the wireless design process. Since Nano WiReach’s firmware is remotely updateable, new security or connectivity protocols do not require application redesign, increased memory, or faster processor speeds.
Nano WiReach supports 10 simultaneous TCP/UDP sockets; two listening TCP sockets; SMTP, MIME, POP3, FTP, Telnet, and HTTP/HTTPS clients; an HTTP/HTTPS embedded Web server with a website for the host application and one for configuring the module. Nano WiReach supports 64/128-bit WEP, WPA/WPA2 (PSK and Enterprise) encryption, AES-128/256, SHA-128/192/256, 3DES; the SSL3/TLS1 protocol for a secure client socket session and a secure FTP session.
