I’ve been entrusted to evaluate the following combination for use in rural and semi-rural situations and would be grateful of some direction please.
Router & Modem: CradlePoint CBA850LP6 EU version with MC400LP6 (MC7455 / EM7455) for operation in the UK.
CradlePoint Firmware: v7.0.70
Modem Firmware: 02.30.01.01_GENERIC,002.045_001 only ‘ticked’ Up to date (i.e. none of the USA AT&T, Sprint or Verizon firmwares are ticked)
Antenna: Poynting XPOL2
Cell Network: Three UK but also could be the others; EE, Vodafone & O2
Bands: Band 1 (10MHz), Band 3 (15MHz) & Band 20 (5MHz). All three are available on the nearby semi-rural test tower 1.5km away with 2CA (Bands 3 & 20) offered by the network & this tower & tested successfully with the Huawei B525-23a (B20+B3) & (B3+B20) and others.
Bands 1 & 3 work OK individually but are not setup for CA by the network or this Sierra Wireless modem I believe.
Band 20 does not work / lock as it comes up as 10MHz instead of 5MHz. In many of the rural use-cases only Band 20 will be available so we need it to work.
Before I plough through the AT! command reference, are there AT! commands that I can enter into the modem to correct this bandwidth issue and ensure that if the tower is enabled for CA the modem will follow suit?
I have used the CLI ‘Band Selection / Locking’ process a few times and as far as I can see I’ve understood and implemented that OK but haven’t yet tried to force a band to have a particular bandwidth as that shouldn’t normally be necessary - should it?
I look forward to hearing from you.
Thanks in advance.
