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

The technology that allows devices to create large-scale networks using point-to-point connections is Wi-Fi Direct. This technology facilitates direct connections between devices without needing a traditional wireless router, enabling a multitude of devices to communicate efficiently with each other. Wi-Fi Direct supports higher data transfer rates and wider range compared to other connection methods, making it ideal for applications that require robust and fast communication among several devices.

While Bluetooth Low Energy, NFC, and standard Bluetooth facilitate connections between devices, they have limitations in terms of range, data rate, or the number of devices that can connect at once. Bluetooth and NFC, for example, are typically suited for low-bandwidth tasks or close-range interactions, whereas Wi-Fi Direct excels in creating broader, high-speed networks suitable for larger data transfers. This makes Wi-Fi Direct particularly useful in applications where many devices need to connect and share data seamlessly.
