1.3.2 Combining Serial and Ethernet Devices
Prior to the introduction of the entraNET series, multiple networks were
often needed to service different types of communication protocols. An
entraNET system provides this functionality through a single AP radio.
Each of the Remote radios in a system can be connected via IP to dif-
ferent SCADA or telemetry hosts, transporting different (or the same)
protocols. Both data streams are completely independent, and the trans-
ceiver provides seamless, simultaneous operation, as shown in
Figure 1-3.

By using a single AP, the cost of infrastructure deployment is cut in half,
with only one antenna, one feedline, and one lightning protector
required. Other cost reductions come from the system as a whole,
including reduced management requirements when using GE
