An Access Point device, such as a wireless router, helps wireless devices connect to a network. Most such points have built-in routers, while others must be connected to a router to provide network access. In any case, the access point is typically hard-wired with other devices, such as network switches or broadband modems.
You can see the access point anywhere, whether home, business or even in public places. In most homes, this access point is a wireless router connected to a DSL or cable modem. But at the same time, some modems also have a wireless facility, making the modem itself an access point.
In large businesses, many access points are provided to easily connect to the central network from any location (the range of the location increases). The public access point can be easily found in shops, coffee shops, restaurants, libraries and other locations. Some smart cities even provide public (public) access points in the form of wireless transmitters connected to streetlights, signs, and other public objects.
While the access point is used to access the Internet wirelessly, some are used only to access a closed network. For example, a business can provide secure access points to its employees to access files randomly from a network server. Most access points provide Wi-Fi access, but an access point can refer to a Bluetooth device or another type of wireless connection. But the main purpose of most access points is to provide internet access to the connected user.
The term “access point” is often used to refer to an abstract term for “base station”, but the base station is only suitable for Wi-Fi devices from a technical point of view. It is also called WAP (or wireless access point). But WAP is not used on-demand like AP (Access Point).
