Telecommunications engineer working to maintain London's phone service during World War 2, in 1942. Telecommunications engineering is a subfield of electronics engineering which seeks to design and devise systems of communication at a distance.
In a cellular system, as the distributed mobile transceivers move from cell to cell during an ongoing continuous communication, switching from one cell frequency to a different cell frequency is done electronically without interruption and without a base station operator or manual switching. This is called the handover or handoff. Typically, a ...
In telecommunications, long-term evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals based on the GSM/EDGE and UMTS/HSPA standards. It improves on those standards' capacity and speed by using a different radio interface and core network improvements.
Communications system engineering is the translation of user requirements for the exchange of information into cost-effective and low-risk technical solutions in terms of equipment and subsystems. Contents
Teletraffic engineering in telecommunications network planning ensures that network costs are minimised without compromising the quality of service (QoS) delivered to the user of the network. This field of engineering is based on probability theory and can be used to analyse mobile radio networks, as well as other telecommunications networks.
Wireless engineering is an engineering subject dealing with engineering problems using wireless technology such as radio communications and radar, but it is more general than the conventional radio engineering. It may include using other techniques such as acoustic, infrared, and optical technologies.
A smartphone is a tool of mobile computing. Mobile computing is human–computer interaction in which a computer is expected to be transported during normal usage and allow for transmission of data, which can include voice and video transmissions. Mobile computing involves mobile communication, mobile hardware, and mobile software ...
With the integration of mobile communication and mobile computing technology, mobile technology has gradually matured, and the mobile interaction brought by the application and development of mobile technology has provided online connection and communication for Ubiquitous Computing and Any time, anywhere Liaison and information exchange ...
