ESTeem Dual Wi-Bridge: Industrial
Wireless Networks X2

2.
ESTeem Horizon series radios can now create two isolated
industrial wireless networks to run side-by-side, seamlessly flowing
across a common wireless infrastructure for secure and segmented
networking.
This feature is available for free by simply updating the Horizon
radios to the latest software version, but how does it work?
Dual Purpose

3.
“Business” Networks
The easiest way to understand what this feature provides is to
consider the two most common radio networks. Figure 1 on the
next slide shows a very common use of the Horizon network where
the high-speed Ethernet interface (up to 1Gbps) provides a bridge
link to a remote facility, miles distant through a repeater site.
The Horizon series radios can operate as both a wireless Ethernet
bridge and Access Point for mobile users to gain thin client access
to the “business” network simultaneously. These mobile clients
may have internet access or access to the business unit’s key data
infrastructure

“Business” Networks
This network can support WiFi clients with the Horizon 2.4 GHz or
Horizon 5.8 GHz or any ESTeem radio in client mode for the
Horizon 900 MHz and Horizon 4.9 GHz.

“Process” Networks
A second common industrial wireless network (Figure 2 on the next
slide) is a SCADA network supporting process or control systems.
This long range, high-speed network provides a redundant Mesh for
remote locations such as pump stations and water tanks.
Operators and support personnel can access the wireless network for
maintenance, on-line programming or system updates.

“Process” Networks
The ESTeem radios handle each of these configurations perfectly. The
challenge is that many customers need both types of systems in a
plant, but each must be mutually excusive without any “crosstalk”.

Same Radios; Separate Networks
This is the perfect scenario for the ESTeem Dual Wi-Bridge
configuration (Figure 3).

8.
Same Radios; Separate Networks
The ESTeem Horizon radios allow each wireless network to operate at
the same time, using the same or independent radio paths but a
complete segregation of data is provided for each network.
Each network will have an independent name (SSID), security settings
and be physically segmented to one of the two Ethernet interfaces in
the radio. Both wireless networks can operate at the same time; mobile
users can select which network to access by their log-in credentials.
This feature of the ESTeem Horizon radios can greatly reduce wireless
network costs while providing the network segmentation between the
“business” and “process” side of the plant.

The ESTeem Advantage
We design, engineer and manufacture industrial wireless radios and modems - all
in the US and all specifically focused on solving our customers’ most difficult
networking challenges, no matter what the frequency.
Through all of those years, we’ve stuck to the philosophy that applications will not
bend to fit the hardware. The solution must fit the application, and we work with
our customers to ensure they get the right wireless solution to fit their needs.
To that end, all of our models come with full compatibility
baked in (195E/Horizon, 192/195 Narrowband), and we
write our software/OS specifically for the components used
for optimum efficiency and performance.
