For users of portable computers equipped for wireless, a hot spot (or hotspot) is a wireless LAN (local area network) node that provides Internet connection and virtual private network (VPN) access from a given location. For example, a business traveller with a laptop equipped for Wi-Fi can look up a local hot spot, contact it, and get connected through its network to reach the Internet and their own company remotely with a secure connection. Increasingly, public places, such as airports, hotels, and coffee shops are providing free wireless access for customers.
