Wireless systems
(OP)
Just wondering what the specification requirements for a wireless system that meets the operational needs of an off-shore petroleum processing platform.
Looking for details covering the functional, operational, performance, and maintenance requirements.
Such things as:
- Data reporting frequency
- Obstruction density
- How to get around obstructions that block, reflect and otherwise impede transmission of wireless signals
- Antenna location
- Report information size (bytes)
- Distance between sensors
Any information about this or where I could obtain some would be greatly appreciated.
Thanks,
Jeremy

I know the following fluid level sensors, pressure, and 4-20 mA wireless battery operated sensors are intrinsically safe, and are being used in some applications to measure the levels in portable tanks used on off-shore platforms. See www.centeron.net
RE: Wireless systems
I am looking for the specifics on wireless systems in general. Such things as Obstruction density, antenna placement etc.. all things that will give us a general idea of what hurdles we have to over come.
If someone has specifics on a wireless system that is in place about any of these areas or related areas I could really use the information or direction as to where to get it.
I'm finding if very difficult to find resources that give me these details.
Thanks,
Jeremy
RE: Wireless systems
The technologies that can help are spread spectrum, Forward Error Correction, diversity antennas, two-way hand-shaking like packet radio ('acks'), etc.
"Wireless" (also known as "Radio") has been around for a while and the failure modes of various bands and techniques are all very well known.

Perhaps that is what we're witnessing.
RE: Wireless systems
That is a scary thought, but hopefully not true. There must be some important RF interference issues since all RF is so close.
RE: Wireless systems
For simple reporting and monitoring applications, wireless is an excellent choice. Especially for tanks that may be moved frequently and sometimes replaced/swapped during a delivery. Additionally, in this application intrinsic safety is a must.
Wireless is ideal where things the items being monitored move, are widely dispursed, or it is just not pratical to put a wired-link between the points. This usually means the items are not part of a active process loop.
