Task Manager Wifi speed units bps <-> Bps?

bobgardner · 10 Sep 2018

My understanding is that bps is bits per second, and Bps is bytes per sec. bps should be 8 times Bps. I'm measuring wifi speed and something looks off. I think they have the units wrong. I think they are reporting in Bps and labeling the graph in bps. So whats a pretty good test? Time how long it takes to send a big file with a watch (you know, the round thing that old folks wear on their wrist?) and see if reality agrees with task manager within a factor of 8? If it takes a program, lets agree on the spec, and hopefully well get it written in c, python, java and something else, but what if the ten forums dudes found a typo in task manager? This started when I was trying to see if I could stream raw audio out the wifi without encoding and decoding. Stream should be 2channels, 2 bytes/sample and 44100 samples/sec, about 176.4K BYTES per sec. Shouldnt show up in task mgr as 174Kbps should it?

Try something like this perhaps?

It starts with Kbps, changes to Mbps and than to MBps reflect actual speed at that time and for graph to stay within limits.

Yes, it shouldn't. It should show ≈1.4Mbps (1411Kbps for 44.1/16 PCM).
Obviously, your stream is somehow encoded to 174Kbps OR you've reached your upload limit.
Task Manager shows only bits per sec and it cannot be wrong.
