Find the LTE channel width used with iPhone.

hi there, sometimes we feel the connection from our iPhone so slow, even we using LTE / 4G not using 3G / HSDPA / HSPA

but sometimes we should know much bandwidth allocated from BTS antena.
how do we check it?

simply press *3001#12345#* then press call
wait for a moment
select "serving cell info"
then you can see Download bandwidth  ....Mhz

lets tell we using 2x2 MIMO
5Mhz bandwith will give 36Mbps
10Mhz bandwitdh give 72Mbps
15Mhz bandwidth give 108Mbps.

so dont expect to get 100Mbps ( as some operator promise ) if the operator only give you 5Mhz LTE Frequency in curent area, because its rf also shared with all user who use the same antena coverage.
