ZyWAN Cellular Routing Modem

Wireless Standards Supported: GSM/GPRS, EVDO, iDEN cellular, GPS, IEEE802.11b

Compatible Operating Systems: Embedded Linux

The ZyWAN is a cellular routing modem for GSM/GPRS, EvDO/1xRTT CDMA and iDEN networks. It
is ideally suited for wireless applications such as internet access, AVL, telemetry,
SCADA, mobile computing, and AMR. A key differentiator is that the ZyWAN operates as a
fully configurable embedded Linux router enabling routing, firewalling, DHCP, DNS and NAT.
The ZyWAN can operate as a terminal server and client, or as a DNS client. Security
features include AES, 3DES, SSH, IPsec and others.

ZyWAN provides network real-time access to any Ethernet,
802.11 or serial device for mobile and fixed data applications. CompactFlash or USB
devices can be used for 802.11b access. A GPS adapter provides a sophisticated tracking
program and raw NMEA data strings for mapping
applications. The adapter can provide serial, UDP or TCP/IP connectivity. The tracking
program reports the device location, speed and heading on regular intervals and caches
data when out of network. To easily manage the ZyWAN, a WEB GUI interface presents a
simple tool to quickly change settings locally or over-the-air. Each of the ZyWAN products
is available in a number of customer
ready application configurations.

A standard DB15 female VGA and touch screen connector is also provided.
