How many SIMs, modems, and bonded connections do you need for IRL?
The most confusing part of IRL, explained. How much connection each bitrate needs, and how to get there, from one phone to a bonded backpack.
Your encoder tops out at 1080p60. A higher-end encoder would go further.

This is the question that decides whether your IRL stream holds: how much connection do you actually need to hit your target quality, and how do you get there? Here is how it works, from one phone to a fully bonded backpack.
The core math
Your stream needs a steady upload, and the rule that keeps you off the BRB screen is simple: only use about 70 percent of your real upload speed, so spikes and packet loss have room. One modern 5G phone gives you maybe 5 to 8 Mbps of usable mobile upload in the real world, and a lot less in a crowd.
- 720p30 needs about 3 Mbps. One good connection is usually enough.
- 720p60 or 1080p30 needs about 4.5 Mbps. One strong 5G line, or two weaker ones bonded.
- 1080p60 needs about 6 Mbps. To hold it in a crowd, you want two bonded connections.
- 1440p (2K) needs about 9 Mbps. Three or more bonded, broadcast-grade territory.
How to add connections
There are three ways to get more pipes, plus a second job of combining them.
- One modern phone with dual eSIM: a primary line plus a backup. This is failover, it switches when one dies, it does not combine them. A great cheap entry, but effectively one pipe.
- Extra phones as hotspots: each tethered phone adds a real pipe you can bond. Cheap if you have old phones lying around.
- Dedicated modems like the Nighthawk: better radios and an ethernet port to wire to the encoder. The real upgrade.
Then you combine the pipes with bonding, and add a relay so a dropped link becomes a BRB, not a restart.
Software bonding that fuses your connections into one. Runs on a phone or a Pi.
