These setups consist of a Nokia Mini Macro 2.5 eNB pole mounted on a macro site connected to sector antennas. Each mini macro is capable of up to 40 MHz of total LTE spectrum for 20+20 B41 carrier aggregation and are now being utilized to bring 2.5 on air if 8T8R equipment is unavailable or does not make monetary sense.

Another update: radio performance isn't quite at the level of my old 5X, but it isn't a massive difference. There are a few places where my 5X would cling to pretty weak LTE and still work; the G5+ drops to 3G in these areas.
Also a huge perk of getting the unlocked variant is the presence of an FM radio app.
