wirelessly

Wirelessly is an adverb describing actions or transmissions that occur without physical wired connections. In technology, it refers to communication or power transfer conducted through electromagnetic waves or other non-contact methods, enabling devices to operate without direct cables.

Common wireless technologies include radio frequency communication such as Wi-Fi (IEEE 802.11), Bluetooth, and cellular networks (3G, 4G, 5G), as well as near-field communication (NFC) and infrared. These systems use antennas and protocols to encode data and manage access to shared media. Wireless data transfer can occur over varying ranges, from millimeters (NFC) to kilometers (cellular).

Power can also be transferred wirelessly in some cases, for example wireless charging using resonant inductive coupling or magnetic resonance. Wireless control and sensing are widespread in consumer electronics and the Internet of Things.

Advantages include mobility, convenience, and reduced cabling. Limitations include potential interference, security risks, power constraints, and dependence on a functioning spectrum and infrastructure. The term wirelessly is commonly used to contrast with wired communication methods such as USB, Ethernet, or coaxial connections.
