Wireless is an old-fashioned term for a radio receiver, referring to its use as a wireless telegraph. The term was widely used in the UK, long after radio was being used for other signals, such as music.

In modern usage, the term refers to communication without cables or cords, chiefly using radio frequency and infrared (i.e., IrDA) waves. E.g., wireless networking of computers.

Method of communication that uses low-powered radio waves to transmit data between devices. High powered transmission sources usually require government licenses to broadcast on a specific wavelength. This platform has historically carried voice and has grown into a large industry, carrying many thousands of broadcasts around the world. Radio waves are now increasingly being used by unregulated computer users.

Software and hardwareHardware is equipment such as fasteners, keys, locks, hinges, wire, chains, plumbing supples, tools, utensils, cutlery and machine parts, especially when they are made of metal. In the United States, hardware has been traditionally sold in " hardware stor developerThe term developer has many meanings: A software developer, one who does computer programming or designs the system to match the requirements of a systems analyst. A real estate developer, one who builds on land or changes and enhances the use of an exists are creating smaller computer networkA wide variety of systems of interconnected components are called networks . Specific examples include: television networks transport networks, roads, railroads, shipping routes and airlines, pipelines (gas, petroleum, water, sewage), electric circuits as which form ad-hoc wireless network, with protocols such as WiFi. The IEEE 802.11 standardThe word standard has several meanings: Classically, standard referred to a flag or banner; especially, a national or other ensign carried into battle; thus "standard bearer" indicates the one who bears, or carries, the standard. The modern primary meanin is for wireless, Ethernet-like LANs. The insecurities in this protocol have popularized the concept of war driving.

Optimal bandwidth routes within wireless networks requires the calculation in real-time of the best way to direct traffic.

Microwave ovens (that cook food) use radiation in the 2.45 GHz range. Cell phones, wireless networking, and other similar tools are in the 2.4 GHz range. This is why proximity to microwaves can disrupt wireless communications
