What is the 228 indoor range, is it recommended for steels coil factory operations ? 

Range in any unique environment needs to be characterized to have any certainty of performance, usually with some kind of live survey. Additionally, you would have to define the antennas used, mounting height, the area around the AP in terms of line of sight, obstructions, etc. Range can be anywhere from 40-50ft to 600m depending on deployment case, antennas, clients used, etc.  

Thanks Howard. the area is 30 m x 228 m. attitude 15 m... alot of steel coil inside

But how is the steel coil arranged? on shelving units, palletized, pictures, etc would help. As far as mounting, is the ceiling 15m or is the ceiling taller with pendant mounts down to 15m?

 

If you assume a coverage radius of approx 30m (again this HIGHLY depends on the edge environment along the permiter as to whether you need two rows of APs or a staggered midline, etc), using a downfiring 90deg directional antenna, you would need a minimum of 8 APs without much overlap. 50% overlap would be 12 APs, 100% overlap for full redundancy would be 16 APs. Then you have to look at client type, but with downfiring directional antennas like the ANT-35A.

 

Also, it's VERY important to note that at 15m the AP-367 is likely a much better alternative. It's less expensive, no need to external connectorized antennas, and the mounting solutions are more cost effective (since you don't need the ADP to use outdoor metal mounting assets on the 228). You may end up needing a few more AP-367s, but the lower overall cost and the much more redueced installation times will more than make up for it. 

 

To compare, if you go with a 228, you need:

 

1 x AP-228

2 x ANT-35A

2 x AP-ANT-MNT-3

1 x AP-270-MNT-ADP

1 x AP-270-MNT-H2 (or H1 if you need adjustment)

 

If you go with an AP-367, you need:

1 x AP-367

1 x AP-270-MNT-H2 (or H1 if you need adjustment)

 

The overall cost of the 367 solution is much much more attractive. 

steel coils arranged in raws. two coils on top of each maximum, they make 15 ft height, they weight around 50000 pounds, the crane moves these coils. 15 meter is from ground to ceiling. The crane operator will be using a tablet connected to the wifi to move the crane. he will be walking between these coils raws..15ft height each side... the data transmitted will be less than 100kb per transaction, 3 seconds of delay is acceptable... but the tablet should never be discounted from the wifi through out the given space.. what do u think ?

Pictures and floor plans would be required to go any further than I've already speculated in terms of total AP count. Be aware too that in many manufacturing facilities, overhead rail cranes can generate a lot of interference in the 2.4Ghz spectrum due ot the high voltage and current of the crane motors. If the tablets are all 2.4Ghz only, you will want to get a spectrum survey as well while the facility is in operation. If the tables support 5Ghz, you should be fine.
