Designing a wireless network is a fascinating endeavor that encompasses various dimensions of modern networking technologies. It involves understanding the characteristics of wireless technologies, planning for coverage and capacity, ensuring the network's security, and devising strategies for interference mitigation. This blog post aims to serve as a comprehensive guide for students and professionals tackling a Wireless Network Design Assignment, focusing on each criterion outlined in the grading rubrics.

Understanding of Wireless Technologies and Standards

WiFi Standards

Understanding wireless technologies begins with familiarizing yourself with different WiFi standards. IEEE 802.11 is the umbrella term for wireless LAN standards, and its various amendments like 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, and the latest 802.11ax (Wi-Fi 6) offer distinct advantages and limitations in terms of speed, frequency, and range.

Approach to Solve the Wireless Network Design Assignment
  • 802.11a: Operates at 5GHz and offers up to 54 Mbps.
  • 802.11b: Operates at 2.4GHz and offers up to 11 Mbps.
  • 802.11g: Operates at 2.4GHz and offers up to 54 Mbps.
  • 802.11n: Operates at both 2.4GHz and 5GHz and offers up to 600 Mbps.
  • 802.11ac: Operates at 5GHz and offers up to 1300 Mbps.
  • 802.11ax (Wi-Fi 6): Operates at both 2.4GHz and 5GHz and offers higher throughput.

Understanding these standards is critical because your design will depend on the requirements of the situation. For instance, if you need high throughput for video streaming, then 802.11ax or 802.11ac would be more appropriate.

Cellular Technologies

Don't forget about cellular technologies like 4G and 5G, which provide an alternative to traditional WiFi for certain use-cases. For instance, if you’re designing a network that involves IoT (Internet of Things) devices in remote areas, cellular connectivity may be more appropriate.

Coverage and Capacity Planning

Site Survey

A site survey is essential to understand the physical layout where the network will be deployed. You can use specialized software tools for this purpose. The survey will help you decide on the number of Access Points (APs) needed, their placement, and the power levels they should operate at.

Capacity Calculation

Estimate the number of devices that will be connected to the network. Make sure to account for peak usage periods. Each AP has a maximum number of devices it can support efficiently.

Security and Authentication Mechanisms


The latest WPA3 (WiFi Protected Access 3) offers robust encryption and is currently the most secure method for protecting a WiFi network. Always opt for the most recent security protocols in your design.


Virtual Private Networks (VPN) offer an additional layer of security, especially for businesses that need to protect sensitive data.


For enterprise networks, Remote Authentication Dial-In User Service (RADIUS) servers provide a centralized way of managing authentication, authorization, and accounting.

Interference Mitigation Strategies

Frequency Planning

Choose channels that are least congested. Most routers offer 'Auto' settings, but for a more customized solution, manual frequency selection is advisable.

AP Positioning

Position your APs in a manner that minimizes interference. Keeping them too close can cause co-channel interference. Keep them too far apart, and you have dead zones.

Quality of Service (QoS)

Implement QoS settings to prioritize traffic. For instance, VoIP could be given higher priority over regular browsing to ensure call quality.

Documentation and Presentation

Network Diagrams

Use software like Microsoft Visio or specialized networking design tools to create comprehensive network diagrams that visually represent your design.

Written Documentation

Your written documentation should explain your design decisions and how they align with the project requirements. It should be clear enough for a person unfamiliar with the project to understand the design, implementation process, and the reasons behind your choices.

Presentation Skills

Finally, how you present your findings can make a significant difference in how your work is perceived. Utilize PowerPoint or similar tools effectively, engage your audience with clear explanations, and make sure to address questions comprehensively.


Designing a wireless network is a multidimensional task that requires a deep understanding of various technologies, meticulous planning, and a focus on security and efficiency. Following the grading rubrics not only ensures a higher grade but also results in a more efficient and secure network design.

By paying attention to each of these categories—Understanding of Wireless Technologies and Standards, Coverage and Capacity Planning, Security and Authentication Mechanisms, Interference Mitiation Strategies, and Documentation and Presentation—you can develop a comprehensive and efficient wireless network design that meets both current and future needs.
