The Cudy LT500 is a Cat41) LTE modem and AC12002) wifi router/repeater. There is relatively little documentation so this page attempts to collect what there is.
The LT's software is a modified OpenWRT or LEDE stack:

It is reported to use a Qualcomm EC25-AFX chip for LTE3) and Mediatek MT7628-series for wifi.
The router is powered by 12vdc, 1A adapter, so should be easy to run off house power.

The LT500 is related to the LT3504), LT400 and LT4505)
It is not immediately clear what the difference is between 450 and 500 besides color.6) When checked, firmwware v.1.3.6 for both was byte-for-byte identical and refers to Mediatek MT7628 chip:

Smart Connect allows separate 2.4/6GHz configurations but presents a single SSID.
Behind the scenes, the router automatically determines whether to connect a device to the 2.4 or 5 GHz band, thereby providing the best speed and range for each device and optimally distributing devices to each network.7)
TR069 appears to refer to this device management spec.
Remote Web seems to be a web proxy setting (untested).
