Infrastructure as a Service.


A technology introduced by Apple that uses sensors to locate iOS or Android devices indoors and can send them notifications via Bluetooth Low Energy (BLE). This can be also used in stores or museums to give further information about item nearby.


Integrated Circuit Chip Identifier.


Also just ID, this marks objects for clear identification. Identifiers are usually letters, words, symbols, or numbers that can also be used to create a code that reveals a definite identity after it is decoded.


Recognizable attributes that are linked to an object, a person, etc. Those attributes expose the entity and allow for clear identification. If two things have the exact same attributes, they usually have the same identity, and they can’t be distinguished from each other.

Identity of Things (IDoT)

An area that involves assigning unique identifiers with associated metadata to devices and objects (things), enabling them to connect and communicate effectively with other entities over the Internet.

IEEE 802.11

The family of specifications developed by the IEEE for wireless LAN (WLAN) communications, first adopted in 1997. The addition of a letter, such as 802.11b, indicates a particular specification.

IEEE 802.11ac

Approved in January 2014, this is a wireless standard for high-throughput wireless local area networks (WLANs) on the 5 GHz band. In contrast to the four MIMO spatial streams in 802.11n, the 802.11ac standard supports eight.

IEEE 802.11n

Builds on previous 802.11 standards to use multiple antennas to increase data rates, adding MIMO to the physical layer. The full specification name is 802.11n-2009, which is an amendment to IEEE 802.11-2007.

IEEE 802.11p

Amends wireless access in vehicular environments (WAVE) to the IEEE 802.11 Wi-Fi standard. The amendment defines a way to wirelessly exchange data without the need to establish a basic service set (BSS), since links to roadside infrastructure may be available only for a limited amount of time. 802.11p uses channels of 10 MHz bandwidth in the 5.9 GHz band.
