Introducing Tornado 251
Tornado 251 takes you beyond the world of cords and cables, providing you with a non-invasive,
wireless, broadband home network. The Tornado 251 system consists of two outlets. The Tornado
251 INT serves as the basis of your home wireless network, while Tornado 251 XTN extend that
network to every corner of your home.
Tornado 251 outlets are IEEE 802.11b/g compliant wireless network solutions, combining standards
based wireless technology with existing telephone wires already in the home. By combining these
features, Wi-Fi signals can be extended easily, providing you with an easy to install, affordable, high-
speed, home network.
Tornado 251 outlets leave your existing phone system intact, allowing the full range of telephony
features, such as call forwarding and caller ID, and telephony hardware such as fax and answering
machines.
In the event of a power outage, Tornado 251 outlets allow direct access to the Public Switched
Telephone Network (PSTN) via a standard RJ-11 phone connector, supporting lifeline services, and
allowing you to place emergency calls.
The Tornado 251 XTN
By plugging Tornado 251 XTN outlets into telephone jacks throughout your home you can benefit
from full wireless coverage at the highest possible Wi-Fi speeds. Normally, as distance from the
transmitting antenna of the Wireless Access Point increases, walls and interference cause signal levels
to decrease, or result in dead spots.
The Tornado 251 XTN outlet overcomes these issues and provides robust performance wherever
needed by boosting signal strength. By cutting the transmission distance from workstation to access
point, the XTN ensures that your broadband services operate near the maximum 802.11g throughput
all the time.
