Optimize network for mobility with RM502Q-AE
Posted: Sun Jul 14, 2024 4:44 pm
I have a RM502Q-AE modem connected to a raspberry pi.
On the modem, I have this antenna: https://www.digikey.ch/en/products/deta ... C/22108774
I am using this setup for streaming while flying a small general aviation plane.
The current modem configuration is the factory default.
I am wondering if there is anything I can do to improve the bandwidth and connection stability.
I need about 2mbit/s upload. I often get about 1.5mbit/s and it can be steady but the connection changes tower, it cuts completely for several seconds.
I am looking for advice like:
- other antenna
- modem configuration change
- linux network stack adjustment
I use modem manager, and here is the output I get:
