Ho un Samsung S7 EDGE H3G con Android 7 (Nougat) e non ho la possibilità di settare la banda del hotspot, è per default di 2.4 Ghz.
Cercando in rete trovo solo discussioni su come fare dando per scontato che vi sia l'opzione.
Appurato che vi è la possibilità, mi viene da pensare che sia un problema di personalizzazione della Tre (3) (H3G).
Riporto la descrizione più completa trovata in rete (io ho solo le voci riportate in grassetto):
