Publication number: 20230198763Abstract: An anonymous, decentralized, high speed, open source, data-only, wireless network is deployed in physical space. A server attached to the network generates a Non-Fungible Token (NFT) and associates the NFT with a first network device (e.g., a cellular antennae) before the first network device is deployed in the cellular network. After deployment of the first network device into the cellular network, a second network device (e.g., a network validator) can identify the first network device with information from the NFT. In this way, a digital token can identify a physical piece of hardware for communications within the cellular network.Type: ApplicationFiled: December 22, 2022Publication date: June 22, 2023Inventors: Anthony LEVANDOWSKI, Oscar ARGUETA, Alexander CHAN, Catherine CULKIN, Kemal FICCI, Sridatta KOMPELLA, Christian KURASEK, Thomas MULROY, Ryan OZAWA, Andrew STEPHENS, Anya ZAYTSEVA
