[Exede] Does Exede really need caps?

So the counter has been down for two weeks now in some areas and people have been going hog wild. I haven't seen any service degradation or interruption, so this begs the question what does a 10gb (or any plan for that matter) cap really do? Are they really necessary? Should the caps be higher for the same price (instead of 10gb make it 20gb for the same price)? I've always imagined the cap helping to ensure quality service, but this usage meter outtage is dissproving that.

When do you think Exede will raise the caps to something more in line with today's internet demands?

Are there other reasons why the cap exists besides QoS or revenue?

If people didn't go crazy with Netflix, torrents, Hulu, etc. I would argue that the caps would be unnecessary. But as is, if the caps were truly eliminated people would jump on all those services in very short time. At that point, even ViaSat-1 would not be able to meet demand. While the service may function fine through these outages, most people don't truly take advantage of them. If they did I think things would be very different.

The primary goal of the caps is to prevent people from wasting bandwidth and to prevent them from using highly intensive services like Netflix.

i beg to differ as the first 5 months of this service for me was unlimited and i saw no problems only the monthly 12 hour DNS outage but that is it i torrented i watched youtube and i skyped and i didn't see one slowdown in service

good point on the Video Services related websites and the torrents for that matter.....

ViaSat-1 throughput = 140 Gigabits/second spread across 72 beams

140 gigabits
(informal notation: kilobyte = 1024 bytes)
bits 150323855360
bytes 18790481920
kilobits 146800640
kilobytes 18350080
megabits 143360
megabytes 17920
gigabits 140
gigabytes 17.5

A 2 hour (7200 seconds) HD Netflix movie is about 3600mb which works out to 4 megabits/second

If my math is correct, if all traffic was theoretically evenly distributed across beams (yes, i know it's not and i don't understand how that balancing works) 35,840 (143360mpbs/4mpbs) users could simultaneously stream HD Netflix movies.

Or 11,946 (12mbps) simultaneous active connections.

Anyone know how many users are on ViaSat-1?

...here's specifics: 285,000 subscribers

Using 72 spot beams in total (63 over continental USA, Alaska and Hawaii, and 9 over Canada), the satellite provides broadband internet service coverage and general communications.

Note - Exede will have commercial accounts (like government/corporate)

hmmmm....i know these numbers aren't super accurate w/o Exede's source data, and usage isn't evenly distributed, but in a given month, exede's max throughput is ~45,360,000 gigabytes.

if there's 285,000 subscribers and let's use the 15gb plan as a baseline, that's 4,275,000 gigabytes Exede has sold to customers /month.

So there's about 41,085,000 gigabytes of capacity left over in a given month.

The problem is people like to use their 15GB all at the same time because it is the most convenient time for them. That is when peak occurs. Caps cannot effectively combat peak time, but they can help limit what it is you are doing during that peak time.

Here's how I imagine their usage chart on a given day.

Each hour has a max of 63,000 gigabytes (516,096,000 mpbs) it can distribute amongst all users across time zones.

That's 143,360mbps/second. If all 285,000 users were simultaneously using the service it would be .5mbps/second for each user. So it would take 16 seconds to download a 1 megabyte file.

Courty3210,

I understand you feel we should have unlimited data caps. However, with satellite technology, it's hard to do because there's a limited amount of bandwidth that one satallite can provide. Because of that, we have put the Data Allowance Policy (DAP) in place to ensure all of our customers receive a fair amount of usage. You can learn more by visiting this link: »www.wildblue.com/legal and clicking on the Data Allowance Policy link.

That's the truth! Even now with the metering off and some people obviously going hog wild we're starting to notice slow downs in the afternoons and evenings.

Zac, i don't mean to infer no caps should exist. This is merely an exercise to learn more about the actual data challenges ViaSat-1 faces. If there's any additional factual information you can provide it would be very useful to the discussion.

1) Actual active customers #'s and their distribution across time zones
2) Accurate peak hours
3) Any obvious capacity information you can provide.

Just seeing if Exede has any documents they can provide with the public.
