Aironet Antenna Selection for Production Facility with High Ceilings
I am hoping someone can help me select the proper antenna and A/P spacing to use on an Aironet 2602E (with 5508 controller) for a project I am designing. The building is a production facility that is currently being built (cannot do a site survey as roof not on yet). The building is 370’ x 800’ but A/P mounting height will be at bottom of roof trusses (34’). Area is wide-open with production machinery at heights of about 20’ max and a few small areas where raw and finished materials are temporarily stored with racks at about 18’. I’ve done installs at height of 23’ with the AIR-ANT2524DW-R dipoles which worked well but am unsure of the additional 11’ in height. I’ve seen some other posts recommending AIR-ANT2544V4M-R and AIR-ANT2566P4W-R but am inconclusive on the best selection and placement.
At that height I would recommend against omni directional. Using omni directional will leave your APs able to hear each other better than the clients.
Your selection of the AIR-ANT2566P4W-R is sound. Even with that radiation pattern your spacing will be pretty generous due to the 34' height. How high will the clients be? Hopefully you can survey with a lift once stationary racks and machinery are in place to get a true view of the coverage.
Angle on the 2566P4W is 105/70 I think, so figure out the pattern in free space, then go from there...
Thanks TJ for the insight. The clients will be at floor level (3'-4' scan guns, laptops, wireless printers). Figuring the 105/70 out I am getting an oblong footprint of around 90'x46' on the floor from the 34' height. Does that seem correct? So my A/P spacing should be approximately 125' apart? What about the A/P's on the longer side of the oblong shape, should they be positioned closer together than 125'?
In addition I was reading that there could be reflectivity causing distortion pointing the directional antenna directly at the ground. Would that apply in this case where it is at a mounting height of 34'?
