We have been working with TVU mobile newsgathering called TM1000 , it uses 6 Modems MC7430 , we want to have 4G coverage all over world , if I use MC7455 and MC7430 we are going to have this coverage ? , or to have this coverage , what modem we should have in addition ?
I know that the device must be firmware compatible to achive this coverage.
Its a bit of a difficult answer because there are caveat and exceptions all over the place but generically speaking yes if you are using these two units they cater for the different frequencies and tech currently deployed globally. There are obviously going to be bands in use that it does not implement but these are going to be exceptions and for some networks there will be specific firmware releases/approvals required.
