Telecommunications infrastructure

communication network where the last link is wireless

device that allows wireless devices to connect to a wired network using Wi-Fi, or related standards

telecommunications system used in public switched telephone networks or in large enterprises

network for communications over distance

system to carry telephone calls

communications channel that connects two or more communicating devices

in telephony, the last part of the connection to the customer

cellular telephone site where antennae and electronic communications equipment are placed — typically on a radio mast, tower, or other raised structure — to create a cell (or adjacent cells) in a cellular network

In telecommunications, a femtocell is a small, low-power cellular base station, typically designed for use in a home or small business. A broader term which is more widespread in the industry is small cell, with femtocell as a subset. It typically connects to the service provider's network via the Internet through a wired broadband link (such as DSL or cable); current designs typically support four to eight simultaneously active mobile phones in a residential setting depending on version number and femtocell hardware, and eight to sixteen mobile phones in enterprise settings. A femtocell allow

Device-to-Device (D2D) communication in cellular networks is defined as direct communication between two mobile users without traversing the Base Station (BS) or core network. D2D communication is generally non-transparent to the cellular network and it can occur on the cellular frequencies (i.e., inband) or unlicensed spectrum (i.e., outband).

E-UTRAN Node B, also known as Evolved Node B (abbreviated as eNodeB or eNB), is the element in E-UTRA of LTE that is the evolution of the element Node B in UTRA of UMTS. It is the hardware that is connected to the mobile phone network that communicates directly wirelessly with mobile handsets (UEs), like a base transceiver station (BTS) in GSM networks. thumb|right|CableFree 4G/5G Remote Radio Head (RRH) with 2x2 MIMO, 2x20W RF power and CPRI fibre interface Traditionally, a Node B has minimum functionality, and is controlled by a Radio Network Controller (RNC).
