It wasn’t long ago that YouTube’s maximum upload size was 10 MB. Then it jumped to 100 MB, followed by 1 GB last fall, followed this week by a new 2 GB ceiling. YouTube’s upload file sizes are increasing to keep pace with the new, cheap HD camcorders on the market. More people are shooting in HD, which means improved video quality, but also much larger file sizes. It also means there’s an increasing need for more upstream bandwidth.
Over the last year we’ve seen massive DOCSIS 3.0 rollouts fueling increased downstream speeds via downstream channel bonding. And the upstream race isn’t far off. However, beyond upstream channel bonding, there are other network-based solutions for increasing upstream throughput. Check out this video of one of my favorite Motorolans, Floyd Wagoner, talking about how to optimize upstream spectrum, specifically in the 5-42 MHz range.
As a special holiday bonus, Floyd goes on to discuss RFOG in this two-minute video as well. Enjoy, and have a Happy Fourth.
