A secure embedded wireless LAN module easily connects embedded devices to 802.11b/g Wireless LAN, 10/100BaseT wired LAN and cellular WAN. The Nano WiReach SMT from Connect One includes the iChip CO2144 IP Communication Controller chip and Marvell 88W8686 WiFi chipset. It is packaged in a 37 x 20 mm RoHS-compliant ultra-slim low-profile 44-pin SMT module form factor with an onboard or external antenna. Nano WiReach SMT simplifies adding Internet connectivity to embedded devices. It does not require any kind of WiFi driver development on the host CPU, and its multiple interfaces (UART, SPI, RMII and USB 1.1) minimize the need to redesign the host device hardware.

Nano WiReach SMT supports several modes of operation. As an embedded router it provides routing facilities between a wired LAN subnet, a WiFi subnet and a cellular WAN connection. It includes a DHCP server, NAT and port forwarding. As a LAN to WiFi Bridge it allows transparent bridging of LAN over WiFi, using direct RMII connection to existing MAC hardware. This allows any microcontroller with a built-in Ethernet MAC to be connected to WiFi, with zero development effort. It can also act as a serial to WiFi ridge allowing transparent bridging of serial over WiFi, using the module’s 3 Mbit/s fast UART.

PPP emulation mode allows existing (e.g., cellular modem) designs currently using PPP to interface to the cellular modem to connect transparently over WiFi with no changes to application or drivers. The Nano WiReach SMT also supports a full Internet controller mode, which allows a simple MCU to use its 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.

Nano WiReach SMT includes RMII, USB, SPI and fast UART interfaces for easy integration into existing or new designs. It offers a highly advanced level of Internet security, including 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.
