Tsn lecture vol 1
This document provides a timeline and overview of the development of telecommunication technologies from 1844 to present day. It begins with early pioneers like Morse and Bell and key innovations like the electric telegraph, telephone, radio, and internet. Diagrams and explanations are provided for how basic telephone systems work through transmitting sound signals and establishing connections. The role of operators in manual telephone exchanges is described. Finally, modern communication applications and typical network architectures are briefly outlined.

Tsn%20 lecture%20vol 2
The document is a lecture on switching systems that discusses:
- The evolution of switching from manual operators to automatic telephone exchanges using digital controls.
- The two main types of switching technologies - circuit switching and packet switching.
- Key aspects of circuit switching networks like dedicated communication paths and potential inefficiencies.
- Components of a telephone exchange like the switching network, signaling, and control subsystems.
Tsn lecture vol 3
The document is a lecture on digital switching systems that contains the following key points:
1. It discusses digital signals, the process of digitization, and quantization levels.
2. It compares the advantages and disadvantages of digital transmission versus analog transmission.
3. It explains different types of data transmission including parallel, serial, asynchronous, and synchronous transmission.
4. It describes different switching techniques used in digital switching systems including space-division switching using crosspoint switches, time-division switching using time-slot interchange, and combined time-space-time switching.
Big data characteristics, value chain and challenges
Abstract—Recently the world is experiencing an deluge of
data from different domains such as telecom, healthcare
and supply chain systems. This growth of data has led to
an explosion, coining the term Big Data. In addition to the
growth in volume, Big Data also exhibits other unique
characteristics, such as velocity and variety. This large
volume, rapidly increasing and verities of data is becoming
the key basis of completion, underpinning new waves of
productivity growth, innovation and customer surplus. Big
Data is about to offer tremendous insight to the
organizations, but the traditional data analysis
architecture is not capable to handle Big Data. Therefore,
it calls for a sophisticated value chain and proper analytics
to unearth the opportunity it holds. This research
identifies the characteristics of Big Data and presents a
sophisticated Big Data value chain as finding of this
research. It also describes the typical challenges of Big
Data, which are required to be solved. As a part of this
research twenty experts from different industries and
academies of Finland were interviewed.
Evolution of the generations of mobile Communication system.
The document outlines the evolution of mobile communication systems from 0G to 4G. It discusses the key technologies and concepts behind each generation including:
- 0G systems used analog radio telephones in cars and early mobile telephone systems.
- 1G systems launched the first commercial cellular networks using analog technology like AMPS.
- 2G introduced digital networks and SMS, using technologies like GSM.
- 3G brought faster data speeds up to 2Mbps using WCDMA, and new applications like video calling and mobile internet.
- 4G aims to provide ultra-broadband speeds from 100Mbps to 1Gbps using LTE and WiMax, competing with home internet speeds
Tsn lecture vol 2
The document provides an overview of switching systems and technologies. It discusses how early telephone networks used manual switching operated by human operators. It then describes the evolution of automatic telephone exchanges using digital controls and technologies like circuit switching and packet switching. It also summarizes Strowger switching, the first widely used automatic telephone exchange system, which uses stepping switches operated by dial pulses to connect calls.
Wireless Body Area Networks
This document discusses wireless body area networks (WBANs) and some of the key considerations for their design and implementation. WBANs allow for communication between devices worn on or implanted in the human body. Key application areas include healthcare, fitness/sports, defense, and entertainment. Moving communications to higher millimeter wave frequencies offers advantages like increased data rates and security, but introduces challenges from atmospheric absorption and varying channel characteristics based on the human body. Ongoing research seeks to better characterize the on-body communication channel and develop optimized antennas and sensor network designs for WBANs.
