A set of commercial-grade modules delivers wireless connectivity environments to in-building or climate-controlled areas in a narrow temperature range (-10° to 65°C). Applications targeting more moderate conditions can choose the commercial-grade Nano WiReach and Nano Socket iWiFi from Connect One for designs because they are 100% compatible in form, fit and function to the original, extended-temperature versions but at a 25% cost reduction.

Based on Connect One’s iChipSec CO2144 IP controller chip, Nano WiReach and Nano Socket iWiFi include a full suite of Internet Protocols and applications, enabling full-featured secure connectivity. Tailored for seamless integration, the modules offer immediate connectivity without WiFi driver development or porting and support several modes of operation. These include an embedded router and embedded access point. With the router mode, LAN or WiFi clients gain a single cellular WAN connection to the Internet (3G router) or routing between LAN and WiFi networks. With the function of embedded access point, devices containing WiFi can connect to the product’s embedded access point to control or manage processes.

Nano WiReach and Nano SocketiWiFi can also function as a LAN to WiFi Bridge. Transparent bridging of LAN over WiFi enables direct RMII connection to existing MAC hardware. Any microcontroller with a built-in Ethernet MAC can be connected to WiFi with zero development effort. The module also has a 3 Mbit/s UART that can bridge serial data over a LAN or WiFi.

Also supported is a full Internet controller mode where simple microcontrollers can use the WiFi modules’ 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. In addition, PPP emulation enables existing (e.g., cellular modem) designs currently using PPP as an interface to the cellular modem to connect transparently over WiFi with no changes to application or drivers.

To ensure Nano WiReach and Nano Socket iWiFi are fully protected from industrial network targeting by hackers—a phenomena more common of late—the WiFi modules offer a highly advanced level of Internet security. Nano WiReach and Nano Socket iWiFi include the latest WiFi encryption algorithms (WPA/WPA2, in both PSK and enterprise modes) and Internet SSL encryption algorithms, as well as serving as an inherent firewall for the industrial application. In providing this level of security, Connect One safeguards the industrial network from attacks originating from the Internet.
