Multi‐well pad
Industry Trend: An increase of horizontal wells
has led to more multi-well pads,
 Multi-well pads require complex automation
solutions.

Pump jacks:

Why is Industrial Wireless Growing?
Field proven secure & reliable technology
Saves money on cable installation
No trenching or conduit installation
Quicker start-up time – no shutdowns
Survives harsh conditions better than wire
Corrosive chemicals, weather, rough handling &
vibration damage networking wire & fiber cable
Why is Industrial Wireless growing?
Economical way to reach (very) remote sites
No hard-to-get phone lines
More reliable than phone lines
No high cost phone line charges
