Hi,
My setup is this:
ZTE MF823 USB modem (LTE Cat3)
Rooter GL AR150 portable router with USB support (powered over POE)
Internal 4G antenna (not sure of the exact model, but looks similar to
https://www.amazon.co.uk//dp/B09C8ZQ5CP)
This equipment is all a few years old, but I've just set it up again with a Smarty Unlimited SIM. I'm located in South-East London, and the equipment is located in my loft, connected via ethernet to my Firebrick FB2900.
Speedtest is reaching a max of about 40Mbits/s download (but mostly around 15-20) and around 15Mbits/s upload, and I'm wondering if there is anything I can do to increase that, or if I am limited by mast congestion. I should be in a 5G area, but I'm not sure I want to go to the expense of a 5G modem.
My modem is showing the following info:
Active band: LTE B3 (1800)
RSSI: -49 dBm (varies between about -42 and -52)
RSRP: -79dBm
SINR: 17dB (varies between about 16 and 20)
If I'm understanding correctly, the RSSI is comfortably "excellent", RSRP is just at the low end of "excellent", whereas the SINR could be a little better (I see 20db+ rated as "excellent").
So I'm wondering what my best bet is for increasing throughput (on a limited budget) ?
