Which technology allows devices to create large-scale networks using point-to-point connections?

The technology that enables devices to create large-scale networks using point-to-point connections is Wi-Fi Direct. This technology allows two or more devices to connect directly without needing a wireless access point, facilitating the establishment of a peer-to-peer network. With Wi-Fi Direct, devices can communicate with each other over Wi-Fi, which is typically faster and has greater range than other connection methods.

While Bluetooth Low Energy is efficient for connecting devices with low power consumption over short distances, it is generally more suited for short-range, low-data-rate applications rather than creating large-scale networks. NFC, being a very short-range technology designed for quick, simple interactions like payments or pairing devices, does not support point-to-point connections on a larger scale. Standard Bluetooth allows for device connectivity but does not support the same range and data throughput capabilities as Wi-Fi Direct, which can handle multiple simultaneous connections effectively.
