Course content

2 sections • 16 lectures • 1h 59m total length

  • What to expect in Aruba Mobility Basics4:55

    Explore the fundamentals of wireless networking, including RF propagation, modulation, channels, power levels, RSSI, and roaming, with emphasis on wireless LAN design and security.

  • Need help?1:54

    Join the course's discord server for centralized, faster support across this and other courses, with optional email or phone verification, and use Udemy Q&A if preferred.

  • Udemy tips and tricks3:20

    Discover practical Udemy interface tips to enhance learning in Aruba Mobility Basics, including playback speed, volume, video quality, captions, transcripts, resources, notes, and offline access.

  • Wired vs Wireless Networking Comparison11:13

    Compare wired and wireless networking, showing wired transmission over bounded cables with switches enabling full-duplex, collision-free domains, while wireless uses shared RF with contention and collision avoidance through access points.

  • Wireless LAN Organizations Setting Standards6:44

    Explore the key wireless LAN standards bodies and certifications that govern deployment, including the IETF, FCC, IEEE, the Wi-Fi Alliance, and Aruba's certification path.

  • Data Modulation Ones and Zeroes11:49

    Explore how data modulation encodes ones and zeros into radio waves using amplitude, frequency, and phase shifts to adapt to interference and path loss for wireless throughput.

  • Major Types of Antennas & how they function11:15

    Learn how antennas convert radio signals into directed coverage, comparing internal and external, omnidirectional and directional designs, including dipole, Yagi, and dish types for floor-to-floor networks.

  • RF Signal Propagation: Signal to Noise Ratio (SNR)8:54

    Learn how RF signal propagation relies on signal to noise ratio and RSSI. Understand how distance, walls, absorption, and interference affect two point four gigahertz and five gigahertz channels.

  • RF Power: Rules of 3 & 107:40

    Measure RF power with milliwatts and DBMS, apply the rules of three and ten to relate power changes to distance and antenna gains, and interpret received signal strength indicators.

  • RF Channels: What are they & how do we use them?10:39

    Learn what RF channels are, compare 2.4 and 5 GHz bands, identify non overlapping channels 1, 6, 11, and explain 20 to 160 MHz widths under FCC rules.

  • MIMO and Co-Channel Interference10:09
  • Planning Concepts: it's important to plan ahead!7:24

    Plan wireless deployments by minimizing competing devices in homes and small offices. Distribute multiple access points, optimize power and channels, and free up air time to reduce interference and collisions.

Requirements

  • Willingness to learn

Description

Welcome!

I'm really happy to announce that I've partnered with Aruba Education Services to bring you this free network security basics course. Learn the basics of ethical hacking and network security with Aruba.


Description:

In Aruba Mobility Basics, you will learn how Radio Frequency (RF) works! You will compare the differences between a wired and a wireless network, identify WLAN organizations that set Wi-Fi standards and the basics of radio communication.  This course introduces you to what goes into setting up a wireless network and how wireless functions at a basic level without requiring any technical experience.

Typical candidates for this course are individuals who are new to networking and want to learn the basics of wireless networking.


Topics:

The course is an introduction to Wireless Networking and covers topics such as:

- WiFi standards

- Radio Frequency (RF)

- WiFi planning concetps

- MIMO

- RF channels

- RF interference


Prerequisites

There are no prerequisite, this course is foundational.
