Hi Richard,


Welcome to Lenovo Community! And happy to have you here.



Well to start off EM7455 comes under CAT-6 category whereas EM7355 CAT-3 from which EM7455 can have a download speed of 300Mbps. And also chances are there for voice support in future firmware upgrade in EM7455.

For quick comaprison go through AirPrime EM7455 vs AirPrime EM735 


I hope the above information helped you.

The number of differences is wide enough, but their significancy for you depends on the cellular operator, its network types and features, customer location, his mobility, needed speed etc. But as you have em7355 the most important feature is your laptop as there is BIOS white list with approved wireless devices for Lenovo laptop. BIOS will not allow to boot the laptop with unapproved wwan modem. It seems you have ThinkPad on Haswell CPU. This generation of laptops doesn't support em7455.
