There are billions of us around the world, who use public channels on a daily basis. This number is growing and is estimated to increase even more in the near future. These public channels such as Television, Radio newspaper, and many others have been integrated into our daily routine where we use them at work, at school and also for entertainment purposes. Our increasing love for public channels is not only affecting how we communicate but it has greatly impacted how we carry and do businesses. Several years back we were completely fine without social media, but can you imagine our world today without social media? Is it even possible to go a day without checking your Facebook or Instagram account?

How have publicinformation channels affected our society?

As we all know how the world has completely been transformedsince the advent of social media and although they have their disadvantagetheir advantages are even more when used as they were meant to be used. Below are some of the impacts of publicchannels that can be seen to have affected our society most.

• They have given us an inside perspective ofplaces that are faraway, the public channel connects the world and throughsharing, we are able to have an inside perspective of foreign places.
• They have helped to respond to disaster in abetter way by reaching the general public on what to do during the occurrenceof disaster and how to respond to it.
• They also help us in tackling some of thebiggest challenges of the world such as climate change and violation of humanrights as public channels enable activitist to be brought together.
• Public channel platforms seem to have a greatimpact on banks as they are changing banking relationships such as improvingcustomer services.
• Public channels also have a great impact on howwe are being governed and how we govern. Public channels are allowing citizensto be the main source of plans, ideas and initiatives in an even easier waythan before and future leaders are expected to embrace this kind oftransparency.

Below are some of the public channels that have been impacting our society greatly in ways that they cannot be ignored.

Television

Television is a reservoir of information in today’s worldand this is where we get all the information from sports, to finance toscience. It is also through this channel that awareness can be spread andeducating the public about general issues that are affecting society and how toapproach them. Moreover, television is one of the best channel to nature newtalents through the numerous reality TV stations where people can showcasetheir talents to millions of people who are watching.

Globalization ofculture also takes place here where we are able to learn and understand thevarious cultures in the world. The negative impacts that this channel hascannot be ignored. Most of our children take most of their time watching thevarious TV programs and they lose concentration in their studies. The TV does not only influence our culturebut it also affects our eating habits.

Radio

Although over the years its popularity has decreased due tothe rising technology, it is a public channel that you are sure to reach almosteveryone nationwide. We all wanthappiness and radio has always played a major role in entertaining us throughmusic and the various interesting Radio talks. It is here that we get toexpress our opinion without any fear of judgement. Since radios are affordableand they are also available in our phones, this has become a major platformwhere if you want to reach many people nationwide, this is the best publicinformation channel to use.

Newspapers

In civil society, newspapers have always been traditionallyimportant. They provide information to the citizens of a country and they havealways served as watchdogs abuses and any form of violation of the rights ofcitizens by those who are in power. At both the local and national level, thereseems to be a positive relationship between the reading of newspaper and civicengagements. It is through here that you see people begin boycotting certainproducts or services in the market or the participation of people in localevents.

Social media

Social media platforms such as twitter, Facebook and Instagram have greatly impacted how we carry out our day to day activities. They have become a major platform for networking, connecting with friends and it is also a major advertising platform for many businesses. It is here that any form of news spreads faster than in any other communication channel.

The power that public communication channel has, it canmanipulate and transform a large population of a given country or even thewhole nation. Public channels can either be used as weapons of destruction orweapons that can be used to build a nation. This power lies in how we use thispublic information channels and this will determine if we will better ourselvesor destroy ourselves.

The lectures introduce principles and functionalities of mobile networks with special focus on currently deployed technologies and future mobile networks. Furthermore, architecture and fundamental principles of GSM, UMTS, LTE and LTE-A will be explained. Then, selected key technologies for future mobile networks (e.g., 5G) will be explained.

Students must have fundamental knowledge of modulations, coding techniques and multiple access methods for wireless networks. Furthermore, they must understand to components of a communication chain, signal propagation and radio channel characteristics (attenuation, gain, interference, noise) and characteristics of spectrum and signals (mean value, energy, power, correlation, etc.). They also should have fundamental knowledge of individual layers of RM-OSI model.
