I just put the S3 ~1 meter far from the router, and started the test. The link speed was 150 Mbps (that’s fine), but the measured performance was only 54 Mbps. This is really slow, it should be at least the half of the link speed as usual. Left side, you can see the graph about the performance.
Compared to my Asus MeMo Pad (it uses 2.4 GHz network, 802.11n), my Asus performed 75 Mbps with the same link speed (150 Mbps) and with the same test environment.
I’m curious if this slow WiFi affects only my Galaxy S3 or other devices are also affected.
Here is the video about the test:
Finally, I repeated the test using 802.11n network (2.4 GHz). The result was also interesting. First of all, the bad news, the link speed was only 72 Mbps. Interesting, because the link speed was 150 Mbps when 5 GHz network was used. I think the network card of S3 supports maximum only this connection speed at 2.4 GHz, but really weird behaviour.
The good news: S3 performed very well in this test, the maximum speed was ~40 Mbps that is a very good value compared to the 72 Mbps of link speed.
And a newer video about this test too:
Samsung Galaxy S3 summary:
|Link speed||150 Mbps (802.11an, 5 GHz)||72 Mbps (802.11n, 2.4 GHz)|
|Real speed||54 Mbps||40 Mbps|
