Qualcomm SDX62 v. Qualcomm SDX65

I've been getting asked this specific question quite a bit lately. Since my guide is by far the most informative part of my website here go the answers :)

Note: the below examples are on the T-Mobile tower located 1 mile from the Chester Tech Repairs retail location.

SDX62 - Quectel RM520N-GL (160MHz)

This module released in 2022 is the absolute KING. Even companies that haven't sold Quectel modems in the passed are using the RM520N-GL now. (I will not name them here, live chat about that if you want to discuss). The benefits of this module as mentioned above is the total bandwidth limit of 160MHz, for example I can get 20MHz of B66 and 120MHz of N41 for a total of 140MHz just about maxing out the RM520 on my tower.

Example of N41 on the 5G Standalone 2 x 5G Bands Carrier Aggregation

Fast forward to end of 2023
SDX65 - Quectel RM521F-GL (300MHz)
This module released end of 2023 is an absolute beast. With a total bandwidth of 300MHz this allows you to do carrier aggregation combos seen only on $1000 flagship smartphones. An example, 20MHz B2 + 20MHZ B2 + 20MHZ B66 + 20MHz B66 + 120Mhz N41 for a total of 200MHz again on my specific tower.

Finally are some real world examples on the my T-Mobile tower
