Adding IP communications over WiFi to serial embedded devices.
Replacing a LAN cable with a WiFi connection.
Adding SSL security to M2M solutions.
Nano WiReach SMT supports several operational modes:
• LAN to WiFi Bridge - allowing transparent bridging of LAN over WiFi, using direct
RMII connection to existing MAC hardware or direct PHY-to-PHY connection.

TM
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 Nano WiReach
SMT’s 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.
• LAN/WiFi Ù Cellular Router – allowing local systems, communicating over LAN
and/or WiFi, to gain WAN access to the Internet via a cellular modem. This mode
includes a DHCP server and NAT to support multiple local systems communicating
over a single cellular link.
