The Deco X20-4G is a dual-band Wi-Fi 6 mesh node with a built-in 4G LTE modem, so it can provide a home network where wired broadband is unavailable or as a backup when the line drops. It delivers up to 1800 Mbps combined (574 Mbps on 2.4 GHz, 1201 Mbps on 5 GHz) and has three gigabit ports that work as WAN or LAN. It suits renters, rural homes and small offices that need a self-contained internet source plus mesh coverage. Against plain Deco X20 units it trades a little simplicity for the cellular radio; against dedicated 4G routers it adds app-managed mesh and Wi-Fi 6. Owners rate it highly overall, though some find the 4G throughput and single-unit coverage limiting.
