2. Wardriving - Wikipedia

   en.wikipedia.org/wiki/Wardriving

   Wardriving is the act of searching for Wi-Fi wireless networks as well as cell towers, usually from a moving vehicle, using a laptop or smartphone. Software for wardriving is freely available on the internet. Warbiking, warcycling, warwalking and similar use the same approach but with other modes of transportation.

3. Wireless network interface controller - Wikipedia

   en.wikipedia.org/wiki/Wireless_network_interface...

   A wireless network interface controller (WNIC) is a network interface controller which connects to a wireless network, such as Wi-Fi, Bluetooth, or LTE (4G) or 5G rather than a wired network, such as an Ethernet network. A WNIC, just like other NICs, works on the layers 1 and 2 of the OSI model and uses an antenna to communicate via radio waves.

4. Mobile radio - Wikipedia

   en.wikipedia.org/wiki/Mobile_radio

   The most common antennas are stainless steel wire or rod whips which protrude vertically from the vehicle. Physics defines the antenna length: length relates to frequency and cannot be arbitrarily lengthened or shortened (more likely) by the end user. The standard "quarter wave" antenna in the 25-50 MHz range can be over nine feet long.

5. Long-range Wi-Fi - Wikipedia

   en.wikipedia.org/wiki/Long-range_Wi-Fi

   Long-range Wi-Fi is used for low-cost, unregulated point-to-point computer network connections, as an alternative to other fixed wireless, cellular networks or satellite Internet access. Wi-Fi networks have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the environment. [1]

6. Wi-Fi - Wikipedia

   en.wikipedia.org/wiki/Wi-Fi

   Wi-Fi (/ ˈ w aɪ f aɪ /) [1] [a] is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves.

7. Smart antenna - Wikipedia

   en.wikipedia.org/wiki/Smart_antenna

   Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.
