Hi would be interesting to know if you support uplink favouring framestructures like (DL:UL): 2:3, 2:7 and others like 7:3 etc
Standard here is 4:1.
Usecase where we are running private 5G network
In addition do you have 2x2 MIMO in TX direction.
Generally the mobile network (via the RRU/RRH) would support the uplink/downlink balance, to which your Peplink / UE would subscribe. In a private network environment you can control this (assuming you control the RRU) or you can request this from your upstream solution provider. Peplink doesn’t create private mobile networks, they are only a supplicant to them in a traditional UE role.
As far as 2x2 MU-MIMO on the uplink, it is specified but is not super common. Again, if you have a private mobile network you may be able to request that MU-MIMO is permitted on the uplink, for the bands (both 4G and 5G) that you are using, but the RRU must support this. From a technical standpoint, the modern (5GN) radios in Peplink devices can support this, but the older 5GH and 5GD radios I’m uncertain of.
Have tested this now with one Teltonika RUTM52 with RM520 Quectel, getting 220Mbps UL, Transit E with RM520 getting 110Mbps, so maybe its only a FW upgrade of the modem? Peplink can maybe confirm?
This is on n40 2300MHz 80MHz bandwidth
Can you share what firmware you’re on? And maybe what firmware you came from? I can look at the Quectel release notes to see if there were updates made to uplink CA.
Hi, running RM520NGLAAR01A08M4G on the modem, transit running latest 8.5.1
Thats the FW out of box, and dosent seem to be any update available.
I’ve worked on a few private 5G network setups, and from what I’ve seen, tweaking the DL:UL ratio can really make a difference, especially when you’re pushing a lot of data in one direction. I’ve used configurations like 2:3 or even 2:7 when there’s more demand on the uplink side. It all depends on the specific requirements of the network. As for 2x2 MIMO in the TX direction, it’s something we’ve utilized in the past to boost uplink performance, and it does help with signal strength and reliability. It’s a pretty standard setup, but it makes a noticeable difference in areas where coverage or interference is a concern.
