Quick question - I have Huawei NCM dongle that I can’t get to work on the NCM protocol but can get a connection via proto 3g in etc/config/network. I don’t care much about 4g speeds, but want to know if I can receive signal on band 12 / 700 Mhz using this setup. Is this possible?
Only 2G (GPRS,EDGE) speed max. 384kbit/s
AT^SYSCFGEX=“01”,3FFFFFFF,2,4,7FFFFFFFFFFFFFFF,
Only 3G (UMTS,HSPA,HSPA+) speed from 384kbit/s to 42Mbite/s
AT^SYSCFGEX=“02”,3FFFFFFF,2,4,7FFFFFFFFFFFFFFF,
Only 4G (LTE) speed max. 150Mbite/s
AT^SYSCFGEX=“03”,3FFFFFFF,2,4,7FFFFFFFFFFFFFFF,
These can also be combined in order of preference, as in:
First preference 3G (UMTS,HSPA,HSPA+) speed from 384kbit/s to 42Mbite/s, then 2G (GPRS,EDGE) speed max. 384kbit/s
AT^SYSCFGEX=“0201”,3FFFFFFF,1,2,7FFFFFFFFFFFFFFF
Of course, not the same ability to specify actual band.
Yes, I can report that these do work with a Huawei MS2372 (and presumably other Huawei modem sticks too). Still haven’t found a way to specify the band or even view which band is currently in use.
If you want set the 2g or 3G band,you can change the “band”,for 4G band,you can change the “lteband”.
For example is specify the LTE band to LTE BC4. :
AT^SYSCFGEX=“00”,3FFFFFFF,1,2,8
Convert the corresponding hexadecimal to binary,the corresponding bit is the corresponding band,the corresponding relationship of 4G lte is as follows:
