Meetinghouse Bandwidth

Postby lajackson » Sun Oct 13, 2013 6:03 pm

I am having trouble understanding the Bandwidth Usage statistic at tm.lds.org and request some help in understanding it.

We have a 2M downlink at the receiving meetinghouse. The bandwidth usage today showed about 900k. Is that a maximum bandwidth?

I ask because we tested a 720k broadcast successfully for two weeks, but today we were not able to stream a 360k broadcast.

Doing the math, if the maximum BW Usage was 900k, the broadcast should have worked even on a 1M downlink. What am I missing?

Good question. I think it has to be averaged over some period of time, but I've no clue about how long/short that is.

What else was using bandwidth?

Probably 500 members. [sigh]

So the bandwidth chart at tm.lds.org is not reliable?
Or I do not know how to properly read it?

I would like to understand what is happening. As I understand the numbers, the broadcast should have worked. But it did not.

I need to find out why before I will obtain permission to try again.

I don't know as it's unreliable, but I'm not sure just how to interpret the results.

The numbers I'm seeing are quite low, so I'm thinking it must be the average over a period of time. The question is - how long?

But I don't know as it's a good tool to use to make a decision on the broadcast. (I see it as more of a tool to justify if your speed should be increased - that is, if that were an option.) I'd use the speedtest when no one else is a around. Then then kill all other users during the broadcast. Physically pull the plug on everyone and everything except what's needed to support the broadcast.

Is this by chance DSL? Because I had a recent DSL install in a chapel that the FMG failed to filter. 1MB instead of 3MB. <sigh>

They are using it for exactly that, or rather, the opposite of that. "You do not need any more bandwidth because you are not using what you have." We have a few hundred members who would disagree with that statement.
