Benefits

  • Hardware-Software Co-Design: Evaluate how WiFi interacts with processors, memory, and buses.
  • Performance Bottleneck Detection: Identify collision hotspots and optimize arbitration.
  • Reliability & Scalability: Model hundreds of devices under realistic loads.
  • Cross-Domain Validation: Combine WiFi with Ethernet, TSN, CAN, and 5G in hybrid systems.
  • Early Trade-Off Analysis: Validate power-saving modes, QoS policies, and retry logic before implementation.

The WiFi Wireless Network model in VisualSim enables architects to simulate the full behavior of wireless communication protocols based on the IEEE 802.11 family. By modeling stations (STAs) and a hub or access point (AP), designers can analyze latency, throughput, contention delays, retries, and fairness under realistic traffic loads.

This model is not limited to standalone WiFi links—it can also be integrated into larger system-on-chip (SoC) models, automotive E/E architectures, industrial IoT networks, and aerospace communication systems. This allows engineers to evaluate end-to-end system performance where WiFi plays a role alongside processors, buses, memory controllers, and wired networks.

Overview

  • Wireless Stations (STAs): Represent wireless devices transmitting data frames.
  • Access Point / Hub: Acts as the central node managing connections and frame forwarding.
  • Contention & Arbitration Logic: Simulates CSMA/CA channel access delays, collisions, and retransmissions.
  • Latency Measurement: Provides detailed analysis of end-to-end transmission delays and jitter.

Supported Standards

VisualSim supports the full range of WiFi standards, ensuring compatibility with both legacy systems and next-generation deployments:

  • 802.11a/b/g – Legacy standards.
  • 802.11n (WiFi 4) – MIMO-based high throughput.
  • 802.11ac (WiFi 5) – Multi-Gigabit wireless.
  • 802.11ax (WiFi 6/6E) – OFDMA, MU-MIMO, extended spectrum.
  • 802.11be (WiFi 7) – Multi-link operation, 320 MHz channels, low-latency streaming.

This ensures users can evaluate coexistence, upgrade strategies, and migration paths from earlier versions to the latest WiFi 7.
