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 ...
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.
Access Point Name. An Access Point Name ( APN) is the name of a gateway [1] between a mobile network ( GSM, GPRS, 3G, 4G and 5G) and another computer network, frequently the public Internet. [2] A mobile device making a data connection must be configured with an APN to present to the carrier. The carrier will then examine this identifier to ...
A mesh basic service set ( MBSS) is a self-contained network of mesh stations that share a mesh profile, defined in 802.11s. [9] Each node may also be an access point hosting its own basic service set, for example using the mesh BSS to provide Internet access for local users. In such a system, the BSS created by the access point is distinct ...
A Network (Layer) Service Access Point Identifier ( NSAPI) is an identifier used in GPRS (cellular data) networks. It is used to identify a Packet Data Protocol (PDP) context (a unique data session) in the Mobile Station (MS) and in the Serving GPRS Support Node (SGSN). It is dynamically selected by the MS (however, the MS should ensure that ...
A public-safety answering point ( PSAP ), sometimes called a public-safety access point, is a type of call center where the public's telephone calls for first responders (such as police, fire department, or emergency medical services / ambulance) are received and handled. It takes calls from any landline, mobile phone line, or VoIP (Voice over ...
A wireless distribution system ( WDS) is a system enabling the wireless interconnection of access points in an IEEE 802.11 network. It allows a wireless network to be expanded using multiple access points without the traditional requirement for a wired backbone to link them. The notable advantage of WDS over other solutions is that it preserves ...
