Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
Long-range Wi-Fi. Long-range Wi-Fi is used for low-cost, unregulated point-to-point computer network connections, as an alternative to other fixed wireless, cellular networks or satellite Internet access . Wi-Fi networks have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the ...
A Service Access Point ( SAP) is an identifying label for network endpoints used in Open Systems Interconnection (OSI) networking. The SAP is a conceptual location at which one OSI layer can request the services of another OSI layer. As an example, PD-SAP or PLME-SAP in IEEE 802.15.4 can be mentioned, where the medium access control (MAC) layer ...
Due to scheduled program upgrades, the Citizen Self Service (CSS) Portal will be unavailable Thursday, March 24 through Sunday, March 27. City staff will also not have access to the system...
Wireless access point. [1] [2] In computer networking, a wireless access point, or more generally 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 connection to a switch or router, but, in a wireless router ...
A network service access point address ( NSAP address ), defined in ISO/IEC 8348, is an identifying label for a service access point (SAP) used in OSI networking. These are roughly comparable to IP addresses used in the Internet Protocol; they can specify a piece of equipment connected to an Asynchronous Transfer Mode (ATM) network.

In telecommunications, a point-to-point connection refers to a communications connection between two communication endpoints or nodes. An example is a telephone call, in which one telephone is connected with one other, and what is said by one caller can only be heard by the other. This is contrasted with a point-to-multipoint or broadcast ...
The access point uses the MIH Command Service to tell the mobile device to initiate handover and includes a list of potential access points. 3. The mobile device MIHF passes this list to its various wireless layers and, using the MIH Information Service, requests them to determine the signal strength of each access point and report back to the ...
Mass-produced Wi-Fi access points equipment on 2.4 GHz and 5 GHz is now being used on nearby amateur frequencies to provide much faster links as HSMM or hinternet. Since it is based on IP, the AMPRNet supports the same transport and application protocols as the rest of the Internet, though there are regulatory restrictions on encryption and ...
