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