MQTT (originally an initialism of MQ Telemetry Transport [a]) is a lightweight, publish-subscribe, machine to machine network protocol for message queue/message queuing service. It is designed for connections with remote locations that have devices with resource constraints or limited network bandwidth , such as in the Internet of Things (IoT).
Mobile architecture. (Redirected from Mobile Architecture) In the past computers needed to be disconnected from their internal network if they needed to be taken or moved anywhere. Mobile architecture allows maintaining this connection whilst during transit. [1] Each day the number of mobile devices is increasing, mobile architecture is the ...
e. The Radio Resource Control (RRC) protocol is used in UMTS, LTE and 5G on the Air interface. It is a layer 3 (Network Layer) protocol used between UE and Base Station. This protocol is specified by 3GPP in TS 25.331 [2] for UMTS, in TS 36.331 [3] for LTE and in TS 38.331 [4] for 5G New Radio. RRC messages are transported via the PDCP -Protocol.
Non-access stratum. Non-access stratum (NAS) is a functional layer in the NR, LTE, UMTS and GSM wireless telecom protocol stacks between the core network and user equipment. [1] This layer is used to manage the establishment of communication sessions and for maintaining continuous communications with the user equipment as it moves.
GPRS Tunnelling Protocol (GTP) is a group of IP -based communications protocols used to carry general packet radio service (GPRS) within GSM, UMTS, LTE and 5G NR radio networks. In 3GPP architectures, GTP and Proxy Mobile IPv6 based interfaces are specified on various interface points. GTP can be decomposed into separate protocols, GTP-C, GTP-U ...
An air gapped network (right) with no connection to a nearby internet-connected network (left) An air gap, air wall, air gapping [1] or disconnected network is a network security measure employed on one or more computers to ensure that a secure computer network is physically isolated from unsecured networks, such as the public Internet or an unsecured local area network.

The RIL provides the system interface between the CellCore layer within the Windows Mobile OS and the radio protocol stack used by the wireless modem hardware. The RIL, therefore, also allows OEMs to integrate a variety of modems into their equipment by providing this interface. The RIL comprises two separate components: a RIL driver, which ...
SDLC. OSI layer. Data link layer. High-Level Data Link Control (HDLC) is a communication protocol used for transmitting data between devices in telecommunication and networking. Developed by the International Organization for Standardization (ISO), it is defined in the standard ISO/IEC 13239:2002. HDLC ensures reliable data transfer, allowing ...
