-### Methodology
+### Subscribers
+
+Charmed Aether SD-Core can stand up **500 concurrent PDU sessions**, the maximum UERANSIM supports.
+
+Further testing would be needed to determine the maximum number of PDU sessions that can be supported by the Core.
+
+## Methodology
+
+### UPF throughput
 
 Tests were performed using `iperf3` to measure the throughput between the
 UE and an iPerf3 server going through the UPF.
@@ -64,3 +72,10 @@ with a bandwidth of 40 MHz. The radio unit used was a USRP B210 and the UE modul
 was a Quectel RM520N-GL over USB.
 
 This test is limited by the radio link configuration.
+
+### Subscribers
+
+The PDU sessions were tested using the UERANSIM simulator on the RAN host.
+
+We used the `--num-of-UE` flag to specify the number of UEs to simulate. We tested
+the maximum number of UEs that UERANSIM supports, which is 500.
