Access point software allows multiple computers to share a single internet connection through a virtual network connection. It can be web-based or create virtual routers. Encryption and authentication are core components. It can be used for home users or enterprise-scale virtual routers.
Access point (AP) software allows multiple computers on a local area network (LAN) to share a single Internet connection. This type of software creates a virtual network connection using a central computer as a gateway. Some types of access point software are web-based and can be used on mobile computing devices, while others create virtual routers using a computer connected to a cable modem. Most software applications create a temporary wireless access point or virtual router.
Computers that are already connected via a local area network can use access point software to route Internet traffic over a single connection. Laptops using wireless technology can connect to the Internet through the LAN connection. For example, a school teacher whose laptop is part of a local domain server can connect to the Internet through the server when the laptop is used in a remote location. Encryption and authentication are typically the core components of this type of access point software.
Home users who may have a virtual LAN set up between two or three computers could use some type of software to share Internet access. Virtual AP software converts one of the computers in a LAN into a wireless access point that a laptop can use. Instead of establishing a physical connection between both computers in a modem or router, one machine can virtually leverage the other’s physical connection. Access point software typically allows users to specify the communication port and access specifications that will be used.
Web-based software allows any laptop to become a wireless bridge or hotspot for other machines. The software may have minimum operating system requirements. A specific application of the programming language may also be required. Once Internet connection sharing is enabled within the computer’s operating system, laptops equipped with wireless technology can use the Internet by connecting to the computer.
Other types of software create a virtual router for computers running certain operating systems. A number of wireless enabled devices may be able to share a single Internet connection through this type of software application. For example, if an individual has a laptop, a smartphone and an MP3 player, they may be able to use the same bandwidth connection across all of these devices. Some simple access point software is provided free of charge, while other types are more sophisticated and include encryption technology.
Companies that may have server software installed on large numbers of computers could create enterprise-scale virtual routers. Some applications allow you to turn encryption features on and off, while other versions maintain encryption at all times. This is often demonstrated when unauthorized users attempt to access secure wireless networks and are prompted for a password or network name.
