Filed:

Jun 17, 2005

Appl. No.:

11/156215

Inventors:

John R. Shepard - Austin TX, US
Joe Nelson - Austin TX, US

Assignee:

Fisher-Rosemount Systems, Inc. - Austin TX

International Classification:

H04L 12/28

US Classification:

370328, 370254, 370401

Abstract:

A wireless communication system for use in a process environment uses mesh and possibly a combination of mesh and point-to-point communications to produce a wireless communication network that can be easily set up, configured, changed and monitored, thereby making a wireless communication network that is less expensive, and more robust and reliable. The wireless communication system allows virtual communication paths to be established and used within the process control system in a manner that is independent of the manner in which the wireless signals are sent between different wireless transmitting and receiving devices within the process plant, to thereby operate in a manner that is independent of the specific messages or virtual communication paths within the process plant. Still further, communication analysis tools are provided to enable a user or operator to view the operation of the wireless communication network to thereby analyze the ongoing operation of the wireless communications within the wireless communication network.

Appl. No.:

11/644758

Inventors:

Joe Nelson - Austin TX, US

Assignee:

Fisher-Rosemount Systems, Inc. - Austin TX

International Classification:

H04W 24/00

US Classification:

4554262, 4554042, 4554561, 455453, 455501, 455522, 455 62, 455 63, 455 6711, 4551151, 340517, 340521, 34053922, 34053929

Abstract:

A wireless communication system for use in a process control environment includes a reference node adapted to determine geographic positions of at least some of the reference node, a base node, and a field node and determine RF power settings of transceivers attached to the reference node, the base node, and the field node based on the position of determined geographic positions. Additionally, the reference node is adapted to determine RF noise level at a plurality of locations within the process control environment at a plurality of times and to adjust the RF power settings based on the determined RF noise levels. The reference node may be implemented on a hand-held device.
