I have one RV50 in a remote location with limited bandwidth (rsrp108,rsrq-14,rssi-77,sinr1.1) Reading through the AT commands I noticed a command !DALSRXBW, see bellow (from AT Command Reference pdf)
My question is, can I reduce the bandwidth (by using this AT command) and increase the sig/noise value thus increasing my overall RSRQ. Right now I have limited bandwidth in this remote location. RSRP and RSSI are good, but my RSRQ is to low to provide the minimal bandwidth needed.
Set LTE Rx bandwidth (LTE only)
Set the LTE Rx bandwidth.
• !DASBAND must be issued before you can use this command.
• This command must be issued before you can use !DALGAVGAGC.
Password required: Yes
• Execution: AT!DALSRXBW=
Purpose: Set the LTE Rx bandwidth.
• 0=1.4 MHz
• 1=3 MHz
• 2=5 MHz
• 3=10 MHz
• 4=15 MHz
• 5=20 MHz
