About IES ECE (Electronics and Communication Engineering)

Electronics & Communication Engineering(ECE) is a versatile branch in the field of engineering. The term "Electronics and Communication Engineering" denotes a broad spectrum engineering stream that integrates many sub streams such as analog electronics, digital electronics, consumer electronics, embedded systems, communication systems and power electronics. The discipline deals with the implementation of principles, applications and algorithms developed within related fields like control systems, radio engineering, telecommunications, computer engineering, instrumentation engineering, signal processing, systems engineering, electric power control, robotics, and many others. ECE handles electronic devices, circuits, communication equipments like transmitter, receiver, integrated circuits (IC).
The dynamic branch not only deals with electronic devices but also software interfaces. It strives to broaden the knowledge and skills of the students on the basic concepts and theories that will equip them in their professional work involving analysis, systems implementation, operation, production, and maintenance of the various applications in the field of Electronics and Communications Engineering.

Exam Pattern for IES ECE

A combined competitive examination is conducted by the Union Public Services Commission (UPSC) for recruitment to the Indian Engineering Services. The Examination constitutes of a written examination followed by an interview for personality test.
Every IES exam is divided into two sections - Paper I & Paper II .
While paper I remains common for all the branches/streams of engineering, the paper II is specialized with respect to the branch of engineering students.
In this case, it is Electronics and Communication Engineering.

IES jobs for ECE

Indian Engineering Services(IES) include technical and managerial services for government of India. The pay scale of Indian Engineering Services is as high as the pay scale of IAS officers.
