I have been using CAP ac for several years, and now I have got CAP XL ac. Taking this opportunity, I made a comparison of access points at home. My conditions: walls made of reinforced concrete. A large number of neighboring access points operate in the 2.4 GHz band (about 20 with a signal level greater than -80 dB, maximum level -40 dB). In the 5 GHz range, there are some free frequencies.
The access point is attached to the ceiling approximately in the center of the apartment and operates in CAPs mode. I tested it using a smartphone (80MHz/1S) and an old laptop (40MHz/2S) in 3 locations: from 3m with almost line of sight to 10m and two walls. After measuring CAP ac, I replaced it with CAP XL ac (the same location and also in the CAPs mode with the same settings). I got the following results:
- 2.4 GHz SAP on a smartphone and on a laptop, the results of CAP ac and CAP XL ac are about the same.
- 5 GHz - the laptop has about the same results as on CAP ac. Smartphone remote location - practically does not work with both AP. At nearby locations, the speed has significantly increased from 150 - 170/160 - 180 to 210 - 240/240 -300
According to data from the WiFi analyzer on a smartphone, the signal levels CAP XL ac are slightly lower compared to CAP ac
These measurements are for rough estimation in my particular case.
