| The [[https://amzn.to/3NmAOzO|Cudy LT500]] is a [[https://www.cablefree.net/wirelesstechnology/4glte/lte-ue-category-class-definitions/|Cat4]]((Up to 150 Mbps Download / 50 Mbps Upload)) LTE modem and [[https://www.tech21century.com/wifi-ac1200-vs-ac1750-vs-ac1900-ac2200-vs-ac3000/|AC1200]]((maximum theoretical combined wifi bandwidth speed is 1200Mbps)) wifi router/repeater. There is relatively little documentation so this page attempts to collect what there is. It is reported to use a Qualcomm EC25-AFX chip for LTE((per amazon listing)) and Mediatek MT7628-series for wifi. | |
