Hi,
Yes the MC7304 from a hardware perspective has the bands for use in EMEA/Oz/APAC where the MC7354 has them for the US. MC74 is the other way around MC7455 is US/EMEA and the MC7430 is APAC. The EM7565 is the first truly global unit where we have been able to integrate all of the relevant bands into a single unit meaning you can load whatever firmware you want onto it for what ever operator you want.
Re the band selection, all generic units come out of our factory with all bands enabled, if they are operator specific i.e. AT&T, Verizon, Telstra, as part of their approval criteria generally we have to set the bands/tech to the ones only for them. Additionally you might want to restrict it to a given band for your own reasons (and there are a lot) but for generic use ‘All bands’ is the normal setting.
Regards
Matt
