1. 3 Questions You Need to Answer to Get the Right
Industrial Wireless Network

2. If you’re looking for an industrial wireless network, you’ve probably already identified
the mobility, distance or accessibility challenges your operation faces that demand a
wireless solution.
You may even feel you’ve identified the right industrial radios for your application, and you
may have even found a provider willing to give you exactly what you’ve asked for.
… Which is where problems can begin to arise. Demanding a specific radio or network
design can be the same thing as telling a doctor to remove your appendix because you
have a stomach ache, and the doctor doing exactly what you’ve asked for – regardless of
whether it will stop your stomach ache.
Prepping for a Wireless Network

3. A reputable provider, on the other hand, will ask you these three seemingly simple
questions to ensure you get the best industrial wireless network for your operation:
1. What distance do you need to cover?
2. What do you need to interface with?
3. What environment will the radios operate in?
The answers to those three questions will provide all the information necessary to design
an industrial wireless network that meets your needs.
What Do You Really Need to Know?

4. Distance
The distance and line of sight (LOS) between antennas has a direct bearing on the best
frequency to use.
Generally, greater distances require higher output power or high-gain antennas.
This answer also informs decisions regarding antennas and the height your radios should
be mounted.

5. Interface
The interface provides information on your communication goals – are you simply
monitoring conditions?
Or are you also displaying video, controlling certain actions or providing emergency
communications?
Each function can require a different type of
radio.
For instance, public service applications,
like fire, ambulance and police
communications, often rely on incredibly
fast response times, which demands a
specific kind of industrial radio.

6. Environment
The environment – outdoor vs. indoor, noisy vs. quiet, dry vs. humid – dictates the type of
hardware needed to create your industrial wireless network.
Oceanside applications, for instance, require clear-coated
components to prevent rust.

7. Once You Know Those Three Things …
Your industrial wireless network provider can answer an even wider range of
complex questions, like:
• What frequency and licensing are required?
• What kind of antennas are needed and what is their best placement?
• What power is needed?
• What data throughput or bandwidth is required?
• Is spread spectrum or frequency hopping necessary or advantageous?
• What signal-to-noise ratio is acceptable for the terrain and application
to produce reliable, trouble-free communication
• Will point-to-point or point-to-multipoint network topologies work best for
your application?
Taken together, all these answers will allow a reputable provider to create the
best industrial wireless network for your operation.
