WiPort Embedded Wireless Device Server User Guide

2: Introduction
WiPort is a wireless embedded device server that provides a network-enabling
solution based on the IEEE 802.11b/g wireless standard. WiPort allows Original
Equipment Manufacturers (OEMs) to add wireless connectivity to their products by
incorporating it onto a circuit board.
The WiPort functions independently of a PC, providing a fully integrated solution that
combines a processor, memory, 802.11b/g transceiver
,
and dual high-speed serial
ports into a single compact module. It includes an operating system, an embedded
Web server, and a full TCP/IP protocol stack. In addition, the WiPort sends email
alerts and supports numerous other network communication protocols, including
ARP, UDP, TCP, ICMP, Telnet, AutoIP, DHCP, HTTP, SNMP, and SMTP.
Wired Equivalent Privacy (WEP) and Wireless Protected Access (WPA) are available
to guarantee the security of the wireless communication. WEP uses an RC4
encryption algorithm with a configured 64-bit or 104-bit key to scramble the data.
WPA uses TKIP, which expands upon WEP by changing the key automatically every
session, detecting intrusion and using improved authentication.
Lantronix's exclusive, patent pending SmartRoam technology takes a proactive
approach to transferring connectivity from one AP (AP) to another AP belonging to
the same ESS (having the same SSID or Network Name). SmartRoam (patent
pending) continuously tracks the signal strength of APs within range to smoothly and
automatically transition to an AP with a stronger signal.
For OEMs who wish to customize the user interface by employing common and
familiar tools, the WiPort serves applets to a Web browser, resulting in interactive
Web pages. This customization of HTML Web pages and configuration screens
tailors the WiPort to fit unique requirements.
