- Channel Access: Designed for 802.11ax the set up OFDMA (Orthogonal Frequency Division Multiple Access) for effective the channel permits in high-density surroundings.
- RTS/CTS such as Request to Send / Clear to Send: Ensure the RTS/CTS mechanisms to decrease the collisions of environments in several APs or dense client populations. This is especially utilized in situations by hidden nodes.
- Implement Quality of Service (QoS) Settings
- 802.11e/WMM (WiFi Multimedia): Setting the WMM to arrange for traffic types like voice, video, best-effort, and background traffic. WMM is vital for applications that needs to low latency and high reliability like VoIP or video conferencing.
- Bandwidth Allocation and Traffic Prioritization: Describe the multiple service of classes to assign the bandwidth terms on application requirements. For sample to assign the higher priority of real-time traffic such as VoIP and lower priority for background traffic like file downloads.
- Set Up Application and Traffic Models
- Realistic User Traffic: To set up the client nodes to create the application-specific traffic like web browsing, file downloads, video streaming, and VoIP. Set packet size, data rate, and frequency based on typical usage patterns.
- Time-Based Traffic Loads: To replicate the peak usage of times through the configuration of time-based traffic loads. For instance, the replicate of higher loads through the business hours and lower loads at night.
- High-Density and High-Mobility Scenarios: In crowded environments such as the stadiums or conference centres to replicate a large number of clients linked to one or several APs. We planned for the mobility scenarios to replication of clients to roam among APs.
- Configure Security Settings
- WPA2/WPA3 Encryption: To utilized the WPA2 (WiFi Protected Access 2) or WPA3 for secure transmissions among APs and clients. WPA3 offered the stronger encode and enhance the security characterize the completed for WPA2.
- Access Control: To set up the access control lists (ACLs) to boundary the permits of authorized devices only, particularly for the enterprise networks.
- Network Isolation and VLANs: To execute the VLANs to distinct the traffic from several user groups for sample the guest, corporate. This increase the security and network management.
- Run the Simulation with Different Scenarios
- Variable Traffic Load Scenarios: Validate the network under several traffic loads to estimate performance, containing the scenarios with light, medium, and heavy usage.
- Roaming and Handoff Scenarios: To replicate with the several APs, test client roaming among APs to estimate the handoff activities and connectivity. Perceive how to faster the clients reconnect and how-to handoffs effect ongoing sessions.
- Interference Testing: To replicate the intrusion from neighbouring WiFi networks or further devices to operating the equal frequency of band. These assistances are permits how to fine the network activity of congested environments.
- Analyse Key Performance Metrics
- Throughput and Bandwidth Utilization: To estimate the data throughput and follow the bandwidth consumption on every AP. High throughput specifies the effectiveness of utilization in WiFi abilities.
- Latency and Jitter: To follow the delay and jitter for real-time applications like VoIP and video. Low latency and minimal jitter are complex for high-quality of real-time transmissions.
- Packet Delivery Ratio (PDR): To measure the ratio of effectively we offered the packets of total packets transferred. A high PDR is significant the consistent network of performance.
- Signal Strength and SNR (Signal-to-Noise Ratio): To calculate the signal strength of SNR to estimate the connectivity of quality. Higher SNR mostly specifies the better activity with fewer transmission errors.
- Client Connection Time and Handoff Success Rate: To evaluate on how rapidly clients link to the network and the success rate of handoffs among APs. Quick reconnections and high handoff success rates show the robust of coverage and seamless connectivity.
