1.2.4 Multiple Protocols and/or Services
Prior to the iNET 900, often two radios were used to service two dif-
ferent types of devices (typically connected to different SCADA hosts)
an iNET 900 provides this functionality with a single remote radio. Each
of the two serial ports can be connected via IP to different SCADA
hosts, transporting different (or the same) protocols. Both data streams
are completely independent and the iNET provides seamless simulta-
neous operation as shown in Figure 1-5.
By using a single radio the cost of deployment is cut in half. Beyond
requiring only one radio instead of two, the biggest cost reduction come
from using half of the required infrastructure at the remote site: one
antenna, one feedline, one lightning protector, and ancillary hardware.
Other cost reductions come from the system as a whole, such as reduced
requirements to manage fewer devices. And above all, the potential to
include the availability of Ethernet and IP services for future applica-
tions, such as video for security, make the use of an iNET 900 for serial
or IP applications, such as video, a very intelligent decision.

1.2.5 Wireless LAN with Extended Range
The iNET 900 is an excellent solution for a long-range industrial wire-
less LAN. An iNET 900 system offers several advantages over commer-
cial solutions—primarily improved performance over extended
distances. The rugged construction of iNET 900 and the extended tem-
perature range make it an ideal solution even when outdoor locations are
required in extreme environmental locations. In many extreme environ-
ments, a simple NEMA enclosure is sufficient to house an iNET 900.
