I am working on a Wireless Modem compatible with Argentinean frequencies. I am planning to replace the current MC7304 used on this Modem with one compatible with Argentinean Mobile frequencies bands.
The Argentinean Mobile Frequencies bands are:
2G: 850 / 1900
3G: 850 / 1900
4G: Band 4 (AWS, 1700*) / Band 28 (APT700, 700 MHz**)
Is it possible to firmware upgrade my MC7304 to be compatible with the Argentinean frequencies bands?
