In computer networks, a wireless access point is a device that allows people to connect Wi-Fi devices such as laptop computers on a wireless LAN, to a wired network. The access point is often connected to a wireless Router.
A wireless ad hoc network uses two or more devices without a wireless access point. Ad hoc networks are easier to set up because an access point is not needed. This makes it similar to Bluetooth.
It is suggested for each access point to only serve 15-25 client devices[1] This depends on the number of devices in an area, the needed speed of data transfer, location and radio channels of the access point, obstacles and more. A repeater, which repeats the signal, can be used to reach farther places.
There are only a few radio channels for wireless networks. Nearby access points may use different channels to prevent them from obstructing each other.
