Can I determine approximate date of manufacture based on MAC address?

[charles_patters]

We found a few Ruckus AP's broadcasting similar names to my client's corporate SSID, but they may be on different floors of our building - that were leased to a different company many years ago.

They are not on my client's floors (weak signal only in one corner near a window) but due to the similarity in SSIDs have now gotten the attention of the security department. They may be on floors higher up  in the building- since my client used to own those floors.

We are curious if the detected MAC addresses could indicate the possible date of manufacture. That could at least indicate if this theory is possible- that they may have been installed years ago, never removed, and left powered.

Getting access to those floors for inspection is not possible yet, without major bureaucratic corporate decisions, hence trying to discern as much as possible with given information.

Sample addresses:
2C:5D:93:14:9E:AC
38:FF:36:17:6A:78
C0:8A:DE:A2:C8:C8

Thanks

Andrew, about how old (years?) are the units you mentioned?

i don't have easy access to those records, but here are the serial numbers for these units, perhaps Michael can look them up?
351205000942 -  7982 - c08a.de
461303001743 -7982- 2c5d.93
441503100298 - R600 - 38ff.36

Hello,
   The first 4 digits of the S/N indicate manufacturing date.  So, the 35th week of 2012 for the first 7982, 46th week of 2013 for the second 7982, and the 44th week of 2015 for your R600.

...and a 99xx, means Jan of that year.
