Technical Field The present disclosure relates to an electronic device providing a service based on network performance information, a mobile robot, and an operating method thereof. 2. Description of Related Art These days, competition in product delivery services in both online and offline markets is becoming fierce. Recently, in order to improve the convenience of customers, some retailers provide a same-day delivery service, by which customers can receive products on the same day as the order. Also, unmanned robots that transport articles have recently been used on land or in the air, and relevant laws are being established. A robot may refer to a machine which automatically handles a given task using its own abilities, or a machine that operates autonomously. In particular, a robot that recognizes an environment and autonomously determines to perform an operation may be referred to as an intelligent robot, and various services may be provided by the intelligent robot. The mobile robot that is disclosed in the related art can adjust the moving speed and rotation radius thereof so as not to be toppled while moving to a destination.\n\nHowever, when the mobile robot of the related art sets a route, the network circumstance is not considered.\n\nRelated Art: Korean Patent Application Publication No. 10-2019-0104268 (publication date: Sep. 9, 2019)\n\nAn aspect of the present disclosure is directed to providing a mobile robot which determines a network shadow region by using a network performance estimation model, and an operating method thereof.",
