Hello, thanks for the reply. I have now collected the cell information and performed **two controlled comparisons between the ZTE MC7010 and the Mudi 7**. Both routers were tested in **exactly the same physical location and using the same SIM card**. For clarity in the attached screenshots: - **1 = ZTE MC7010** - **2 = Mudi 7** - 🟢 **Green = daytime test, around 14:30** - 🟡 **Yellow = night test, around 01:10** * * * ## 🟢 Daytime test, around 14:30 ### 🟢 1 - ZTE MC7010 | Carrier | Band | EARFCN / ARFCN | PCI | BW | RSRP | RSRQ | SINR | | --- | --- | --- | --- | --- | --- | --- | --- | | LTE PCC | B7 | 2850 | 426 | 20 MHz | -100 dBm | -16 dB | 20.8 dB | | LTE SCC | B3 | 1301 | 454 | 20 MHz | | | | | NR | n1 | 432290 | 329 | | -90 dBm | -11 dB | 26.5 dB | **Speedtest: 295 Mbps download / 75.0 Mbps upload** ### 🟢 2 - Mudi 7 **AT+QCAINFO:** ```auto +QCAINFO: "PCC",2850,100,"LTE BAND 7",5,426,-102,-16,-64,18 +QCAINFO: "SCC",1301,100,"LTE BAND 3",2,454,-101,-16,-64,4,0,-,- +QCAINFO: "SCC",432290,2,"NR5G BAND 1",329,-90,-11,2707 OK ``` **Speedtest: 254 Mbps download / 22.2 Mbps upload** ### Daytime comparison Both routers were using exactly: - **LTE PCC: B7 / EARFCN 2850 / PCI 426** - **LTE SCC: B3 / EARFCN 1301 / PCI 454** - **NR: n1 / ARFCN 432290 / PCI 329** | | ZTE MC7010 | Mudi 7 | | --- | --- | --- | | Download | **295 Mbps** | **254 Mbps** | | Upload | **75.0 Mbps** | **22.2 Mbps** | The **22.2 Mbps upload on the Mudi 7 is actually one of the better upload results I have obtained from it with this setup**. I also checked the Mudi 7 web interface again with this B7 + B3 + n1 configuration. It reports: - **Network type:** 5G NSA - **TAC:** 77B1 - **Cell ID:** 494DD0C | Band | Bandwidth | ARFCN | PCI | RSRP | SINR | RSRQ | RSSI | | --- | --- | --- | --- | --- | --- | --- | --- | | B7 | 20 MHz | 2850 | 426 | -104 dB | 19 dB | -17 dBm | -65 dBm | | B3 | 20 MHz | 1301 | 454 | -99 dB | - | -15 dBm | -66 dBm | | n1 | 15 MHz | 432290 | 329 | -88 dB | - | -11 dBm | - | I am including the **Cell ID reported by the GL.iNet interface** , but I would prefer to verify/collect the Cell ID directly from the modem. **If you can provide the AT command you would like me to use, I can run it and provide the complete output.** * * * ## 🟡 Night test, around 01:10 ### 🟡 1 - ZTE MC7010 | Carrier | Band | EARFCN / ARFCN | PCI | RSRP | RSRQ | SINR | | --- | --- | --- | --- | --- | --- | --- | | LTE PCC | B3 | 1301 | 143 | -101 dBm | -12 dB | 5.2 dB | | LTE SCC | None | | | | | | | NR | n1 | 432290 | 329 | -84 dBm | -11 dB | 18.0 dB | **Speedtest: 160 Mbps download / 39.8 Mbps upload** ### 🟡 2 - Mudi 7 **AT+QCAINFO:** ```auto +QCAINFO: "PCC",1301,100,"LTE BAND 3",5,143,-104,-12,-70,17 +QCAINFO: "SCC",432290,2,"NR5G BAND 1",329,-101,-11,683 OK ``` **Speedtest: 127 Mbps download / 17.7 Mbps upload** ### Night comparison Again, both routers were using exactly: - **LTE PCC: B3 / EARFCN 1301 / PCI 143** - **LTE SCC: none on either router** - **NR: n1 / ARFCN 432290 / PCI 329** | | ZTE MC7010 | Mudi 7 | | --- | --- | --- | | Download | **160 Mbps** | **127 Mbps** | | Upload | **39.8 Mbps** | **17.7 Mbps** | * * * The download performance is reasonably close, but the **upload difference remains substantial even when the serving bands, frequencies and PCIs are matched between the two routers**. For the **green/daytime test** , I also took a screenshot of the Mudi 7 web interface shortly afterwards, at **15:17** , The GL.iNet interface reports: - **TAC:** 77B1 - **Cell ID:** 494DD0C However, I am not sure whether the Cell ID displayed by the web interface is the most appropriate value for the detailed comparison you are requesting. If possible, could you please provide the **AT command you would prefer me to use to retrieve the Cell ID directly from the modem**? I can then run it on the Mudi 7 and provide the raw output. Thank you. Ps,i have pictures but the forum doesn’t allow me to upload them ---

Appreciated for the updates. The E5800 and ZTE device’s band settings look similar. I've passed this on to dev team. The cellular speed issue is a bit tricky since it often involves base station information, but we're looking into it. Thanks again for the info. ---

Please try disabling the 2.4 GHz Wi-Fi radio and run the speed test again. While the modem is registered on LTE Band 7, check whether the performance improves. Before the test, access the router via SSH and enable cellular debugging: ```auto Cellular_debug.sh 1 ``` Then enable UL MCS reporting once: ```auto AT+QNWCFG="nr5g_ulMCS",1 ``` During the speed test, collect the output of: ```auto AT+QNWCFG="nr5g_mimo_info" AT+QNWCFG="nr5g_ulMCS" AT+QCAINFO AT+QRSRP AT+QRSRQ AT+QSINR AT+QENG="servingcell" ``` After the test, disable UL MCS reporting and cellular debugging: ```auto AT+QNWCFG="nr5g_ulMCS",0 ``` ```auto Cellular_debug.sh 0 ``` Finally, export `/tmp/cellular_manager.log` and send us the log, AT command outputs, and speed-test results for further analysis. ---
