In computer networking, a wireless access point (WAP) (also just access point (AP)) is a networking hardware device that allows other Wi-Fi devices to connect to a wired network or wireless network. As a standalone device, the AP may have a wired or wireless connection to a switch or router , but in a wireless router it can also be an integral ...
A temporary network created by a cellular telephone to share its Internet access with other devices is a common example. In contrast to the stations in an infrastructure-mode network, the stations in a wireless ad hoc network communicate directly with one another, i.e. without a dependence on a distribution point to relay traffic between them.

An 802.11n-only network may be impractical for many users because they need to support legacy equipment that still is 802.11b/g only. In a mixed-mode system, an optimal solution would be to use a dual-radio access point and place the 802.11b/g traffic on the 2.4 GHz radio and the 802.11n traffic on the 5 GHz radio. [20]
This Linksys WRT54GS, a combined router and Wi‑Fi access point, operates using the 802.11g standard in the 2.4 GHz ISM band using signalling rates up to 54 Mbit/s. IEEE 802.11 Wi-fi networks are the most widely used wireless networks in the world, connecting devices like laptops (left) to the internet through a wireless router (right).
802.11g is the third modulation standard for wireless LANs.It works in the 2.4 GHz band (like 802.11b) but operates at a maximum raw data rate of 54 Mbit/s.Using the CSMA/CA transmission scheme, 31.4 Mbit/s [9] is the maximum net throughput possible for packets of 1500 bytes in size and a 54 Mbit/s wireless rate (identical to 802.11a core, except for some additional legacy overhead for ...
802.11ac-class device wireless speeds are often advertised as AC followed by a number, that number being the highest link rates in Mbit/s of all the simultaneously-usable radios in the device added up. For example, an AC1900 access point might have 600 Mbit/s capability on its 2.4 GHz radio and 1300 Mbit/s capability on its 5 GHz radio.
Wi-Fi client devices typically connect to the access point that can provide the strongest signal within that service set. [109] Increasing the number of Wi-Fi access points for a network provides redundancy, better range, support for fast handover, and increased overall network capacity by using more channels or by defining smaller cells.
This will add another 12/13 Channels to the overall 5 GHz band enabling significant overall wireless network capacity enabling the possibility of 24+ channels in some countries. 802.11a is not interoperable with 802.11b as they operate on separate bands. Most enterprise class Access Points have dual band capability.
