What is difference between n28 international band and Indian band?

Device supports n28 international band, but not n28 Indian band.

So it won’t be able to support n28 band with FOTA / OTA update as well?

India or APAC follows hormonised APT700, n28. 698–806mhz with GB.

However rest of World (esp USA) its segmented freq, bamdwidth hence its not harmonised across.

Thanks!

If specification says device supports n28 international band and n28 indian band is not supported. So in future can device support n28 indian with fota/software update?

Depends on chipset.

Mostly it won’t since filter are not designed adjacent overlapping spectrum.

E.g. India 900 MHz is B0 not B8. (E and P GSM version)
