Patent number: 11425652Abstract: Deployment of Internet-of-things devices can comprise sensors deployed in remote and hard to reach areas and locations. Due to lack of access to reliable power, these sensors cannot always be connected to a network and also have limited computation power. Consequently, a mechanism can be established to periodically access these sensors and collect data from them. The mechanism can utilize a mobile radio unit device to serve as data collectors. The mobile radio unit device can make use of an adaptive beam scanning to perform sensory data collection via the beam scanning operation. Additionally, the platform can also comprise a radio access network intelligent controller to manage the data collecting radio units by providing specific instructions and data collection methodologies.Type: GrantFiled: November 24, 2020Date of Patent: August 23, 2022Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Mostafa Tofighbakhsh, Shraboni Jana, Bogdan Ungureanu, Deva-Datta Sharma, Rittwik Jana
