ALFA Network AWUS036NHA
The device identifies as an Atheros UB91C.
The Wi-Fi IC would appear to also vary between newer and older units.
- Older devices likely use AR9271 (AR9271-AL1A).. while newer ones may
- use AR9271L (AR9271L-AL3A). Both are pictured in the images below.
- 'The L stands for "Low-Cost".', per Sujith on ath9k-devel if it's cheap per sujith it's also Low-power per our tests
The power amplifier connected as fallowing:
- 67 - XPABIAS - (Analog Output) connected with EN(able) pin of external Power Amp.
- 68 - PDET - (Analog Input) connected with DET ping of external Power Amp.
The LED on this device is blue.
- The FCC ID would appear to only be printed on the label of newer units.
FCC test results
- Radiated power (with antenna): 90 dBuV/m peak (802.11b AVG of CH1,CH11)
- Output power (before antenna): 10.41 dBm peak (802.11b CH6) (10.99mW)
According to FCC test results, this adapter is ~5 times weaker (sure it's "weaker" just as "L" stands for "Low cost" details: https://github.com/qca/open-ath9k-htc-firmware/issues/82#issuecomment-252649735)
- than typical Wi-Fi adapters such as TP-LINK TL-WN722N. Although it's flagged high-power manufacturer never released driver to support high-power operation.
802.11bgn: 2.237-2.484 GHz
