Using Infrared Light to Communicate Wirelessly

1. Using Infrared Light to Communicate Wirelessly

Infrared Light is used in wireless network communications due to its safety, security, and speed. This lesson gives you a clear idea about wireless infrared communication and its advantages, limitations, and applications.

What is Optical Fiber? - Definition & Concept

2. What is Optical Fiber? - Definition & Concept

Optical fiber is a type of cabling technology that uses light to carry voice and data communications (telecommunications) over distances both great and small. This lesson will provide a definition of optical fiber, explore the different types and explain how the different types are used. We'll also look at the advantages of optical fiber over traditional copper wiring and examine the limitations.

Synchronous Optical Networking: Definition & Application

3. Synchronous Optical Networking: Definition & Application

SONET is a high-speed data transmission protocol over optical fibres. Here we will learn about SONET (Synchronous Optical Networking), its evolution, working, its advantages over other protocols and application areas.

What is Li-Fi? - Definition & Comparison to Wi-Fi

4. What is Li-Fi? - Definition & Comparison to Wi-Fi

Light-based networking technology is not new, but may soon compete with traditional Wi-Fi offerings. In this lesson, you'll learn more about Li-Fi, how it works and how it compares to the Wi-Fi of today.

Point-to-Point Link-Based Systems: Definition & Uses

5. Point-to-Point Link-Based Systems: Definition & Uses

Point-to-point link-based systems provide a high-bandwidth and a dedicated connection between two systems. This lesson describes the Point-to-Point Protocol that establishes point-to-point links, working, applications and so on.

Practical Application for Wireless & Mobile Networking: Using Light-Based Wireless Networks

6. Practical Application for Wireless & Mobile Networking: Using Light-Based Wireless Networks

In this practical lesson, we'll explore some basic concepts of light-based wireless networks. We'll also consider some of the major characteristics of this new technology that differentiate it from radio-based wireless networks.
