The module is power-efficient: the core operates at 1.2V, while I/Os operate at 3.3V. Power Save mode further reduces power consumption. WiReach BK is a secure serial-to-
Wireless LAN device server module that also acts as a bridge to connect serial devices to 802.11b/g Wireless LANs. It includes the iChip CO2144 IP Communication Controller chip and Marvell 88W8686 WiFi chipset. It is packaged in RoHS-compliant ultra-slim form factor and uses an industry standard pin-out. WiReach BK offers much more than many other device servers on the market. It acts as a security gap between the application and the network;
supports up to 10 simultaneous TCP/UDP sockets; two listening sockets;
a web server with two websites; SMTP and POP3 clients; MIME attachments;
FTP and TELNET clients, and SerialNET mode for serial-to-IP bridging. WiReach BK supports the SSL3/TLS1 protocol for secure sockets, HTTPS and FTPS, WEP, WPA and WPA2 WiFi encryption. WiReach BK minimizes the need to redesign the host device hardware. It easily inserts into headers on the host PCB and connects to an external antenna. Minimal or no software configuration is needed for WiReach BK to access the Wireless LAN. Connect Ones high-level AT+i API eliminates the need to add WiFi drivers, security and networking protocols and tasks to the host application. The AT+i SerialNET operating mode offers a true plug-and-play mode that eliminates any changes to the host application. 1.2 Hardware Description Size: 46.2 x 25.4 x 5.0 mm

WiReach BK Data Sheet 2-1 Connect One Typical Applications 3 Typical Applications Adding IP communications over WiFi to serial embedded devices. Adding SSL security to M2M solutions. WiReach BK supports several operational modes:
SerialNetTM Serial to WiFi Bridge - allowing transparent bridging of Serial over WiFi, using a 3Mbps fast UART. This is a true plug-and-play mode that eliminates any changes to the host application. PPP modem emulation allowing existing (i.e. modem) designs currently using PPP to connect transparently over WiFi. Full Internet Controller mode allowing simple MCU to use the WiReach BKs rich protocol and application capabilities to perform complex Internet operations such as E-mail, FTP, SSL, embedded Web server and others. It also acts as a firewall, providing a security gap between the application and the network.
