Not sure of your level of knowledge on bandwidth, but this info simplifies it for anyone that gets confused between different types of transmission and when it’s truly important to have dedicated high bandwidth on upload.
For 1080p (Full HD) streaming:
Download (receive):
Typical bitrate: ~5 to 8 Mbps (Netflix recommends 5 Mbps minimum for 1080p).
Data consumption: About 2.25 GB to 3.6 GB per hour.
Upload (send):
Only a few Kbps (kilobits per second), maybe 20-50 Kbps — practically negligible.
For 4K (Ultra HD) streaming:
Download (receive):
Typical bitrate: ~15 to 25 Mbps (Netflix recommends 15 Mbps minimum for 4K).
Data consumption: About 7 GB to 11 GB per hour.
Upload (send):
Again, very small, maybe 20-100 Kbps depending on the streaming app — still negligible.
—When High Upload Bandwidth is Needed—
Upload-heavy activities happen when the user needs to send a lot of data out to the internet, not just receive
For Consumers:
High upload is needed when doing things like:
Video conferencing (Zoom, Microsoft Teams, FaceTime, Google Meet) — HD video calls can need 2–6 Mbps upload per user.
Uploading videos (YouTube creators, TikTok uploads) — especially large, long videos (e.g., 4K files can be several GBs).
Online gaming — not much upload per se (~0.5–2 Mbps), but it demands low latency and consistent upload quality. Mainly, games that require a lot of upload will default to the user with the best connection when doing Team DeathMatch.
I had my daughter test another service 2 years ago with 10 Mbps upload while Competitively Gaming and had no issies.
Cloud backups (Google Drive, iCloud, OneDrive) — uploading large folders/photos/videos.
Live streaming (Twitch, Facebook Live) — needs anywhere from 3 Mbps (720p) to 10+ Mbps (4K live streaming) steady upload.
Home security systems — multiple cameras continuously uploading video streams to the cloud (especially in high resolution). This depends on the quality of the NVR. Most are set to minimum settings and most consumers don’t change these defaults.
Remote work — uploading documents, CAD files, design assets, etc.
For Businesses:
Businesses typically need much higher upload bandwidth than homes, especially:
Remote collaboration — constant file syncing (e.g., Dropbox Business, SharePoint).
VoIP systems (Voice over IP phone services) — many simultaneous voice calls can consume lots of steady upload.
Hosting services — if a business hosts its own servers (e.g., websites, email, CRM) at its office.
Cloud-based services — heavy use of SaaS platforms like Salesforce, cloud accounting, CRM, etc.
Large file transfers — sending customer data, product updates, software builds, etc.
Video conferencing rooms — multiple HD video streams going out at the same time (important for hybrid offices).
Surveillance systems — businesses may have 20–100 security cameras uploading to offsite/cloud storage 24/7. Alternatively, if a business with inhouse storage wants to receive 4k video, live, that is the only time they will need higher bandwidth.
For most Small Businesses, high upload is negligible.
Backup and Disaster Recovery — scheduled large backups of business data to cloud services.
