WLAN (abbreviation for Wireless Local Area Network) is the wireless communication of local or even more distant (radio links) computers or terminals. Hot spots are public Internet access points, e.g., in train stations, at airports, in libraries, but also in hotels or restaurants, which are becoming increasingly important. Users log on with their devices via a WLAN access point and can thus access the Internet via the hotspot. VPN is recommended for the secure use of such hotspots.
Bluetooth is also a transmission standard that connects devices over short distances using radio waves. Bluetooth software is needed to provide Bluetooth functionality for PCs or laptops and to ensure support for connected Bluetooth devices (headsets, speakers, etc.). In this current market overview you will find software and tools that support transmission via WLAN or Bluetooth.
