About This Chapter
Radio-Based Wireless Networks - Chapter Summary
In this chapter, you'll review bite-sized lessons that outline the fundamentals of radio-based networks. Using a simplified and engaging teaching style, our computer science instructors explain the key differences between several network types, such as cellular networks, ultra wideband networks and sensor networks. You'll also see how radio waves and magnetic induction makes wireless communications possible. Following each lesson is a short quiz that helps you check your understanding of the material. If you have any questions along the way, you can always reach out to our subject-matter experts online. Use any computer or mobile device to study, and when you're finished, you should be able to:
- Discuss the uses of radio waves
- Facilitate wireless networking with magnetic induction
- Use cellular networks and ultra wideband networks for wireless communications
- Differentiate between CDMA and GSM
- Explain how sensor networks operate
- Describe the purpose of application in the Internet of things
- Select radio-based wireless networks
1. Radio Wave: Definition, Spectrum & Uses
Radio waves are used in almost all forms of wireless communication, and you certainly utilize them every day! In this lesson, learn more about how radio waves are produced, and then learn about the different types of radio waves and how they are used.
2. Using Magnetic Induction to Facilitate Wireless Networking
Magnetic Induction (MI) has emerged as an alternative to traditional wireless communication, especially for underground and underwater communication. Let us discuss MI based wireless communication in detail.
3. Using Ultra Wideband Networks for Wireless Communications
Ultra-Wideband Communications are not new and undoubtedly not very well known either, but it has been necessary for the industry. This lesson will take you through its history, real-world uses, and where it is most useful.
4. Using Cellular Networks for Wireless Communications
A cellular network is a mobile network (radio network) for wireless mobile communication. The cellular networks face great growth with the invention of technologies like GSM, GPRS, CDMA, and so on. This lesson gives an overview of cellular networks and how they work, their applications and major features.
5. GSM & CDMA: Definition & Differences
Cell phones are a big part of most people's lives these days. But how is it that you can talk to another person? How are the billions of calls that happen everyday handled? In this lesson, we'll take a look at two cell phone communications technologies, GSM and CDMA, what they are, and how they differ.
6. Sensor Networks: Definition, Operation & Relationship
A sensor network connects numerous sensor nodes that can detect information such as heat, pressure, and motion. With the rapid development of sensors, sensor networks are a vital part of the internet of things (IoT) and the modern world. In this lesson, we will define sensor networks, their components, their operation, implementation, and uses.
7. Application in Internet of Things: Definition & Purpose
In this lesson we will first understand the concept of the internet of things. Next we will learn about various applications involved with the internet of things which could be used in our everyday lives and what purpose they would serve.
