Module 7- Telecommunications


Module 7 Objectives

Describe the components of voice and data networks.
Describe essential features of cellular networks.
Describe additional methods of wireless data networking.

 

 Telecommunications refers to the electronic transmission and reception of signals for voice and data communications.

Telecommunications (telecom) networks play a vital role in our daily activities. From the global telecom networks that make up the Internet, to short-°©range wireless technologies that pass data back and forth between a mobile phone and an automobile’s media system, telecommunications technologies keep people and devices continuously connected.

Today, more than 72% of U.S. citizens own a smartphone. Statistics are similar in many developed nations around the world. A recent Pew survey found that smartphone ownership rates in emerging and developing nations are rising at an extraordinary rate, climbing from a median of 21% in 2013 to 37% in 2015. The survey concludes that overwhelming majorities in almost every nation surveyed report

owning some form of mobile device, even if they are not considered “smartphones.”

7.1 - Telecommunications

In telecommunications, infrastructure  refers to the hardware, software, and protocols that support telecommunications.

Both voice and data communications have become an important part of our daily lives. Understanding the hardware, software, and protocols that support this useful technology can help you select telecommunications services that are best suited to your needs.

7.2 - Cellular Networks

A cellular network  is a wide area network in which a geographic area is divided into cells, with a transceiver antenna (tower) and station at the center of each cell, to support wireless mobile communications.

Cellular network technologies have altered the way people live. Originally designed to support only voice communications, cellular technology has progressed to support data communications over the Internet. Today, more people access the Internet on cellular phones than any other type of computing device. Mobile technologies allow people to work more efficiently and flexibly. Cell phones have

become a necessity in many cultures. To gain the most benefits from cellular technology, it helps to understand how the technology works and what services it provides.

7.3 - Wireless Networking

Wireless data communications refers to telecommunications that take place over the air to provide data and Internet access.

Access to information anywhere, anytime has been a dream for many technology enthusiasts—a dream that has become a reality. Many wireless technologies are available for accessing data and information from various locations. Those who understand those technologies can lead more productive lives. Many wireless technologies are used to access different types of data and information from various

environments. Some, like GPS, have very specific functions. Others, such as Wi-Fi and Bluetooth, have become standards used by many every day for a variety of purposes. Combined, these wireless technologies are transforming our lives by making communication and access to information effortless from any place at any time. This section covers the most useful wireless data technologies available

today.
