Advanced Wireless Configuration
1. Wireless Mesh Networks
Wireless Mesh Networks (WMNs) are a type of network where each node (or access point) can relay data for other nodes, creating a mesh of interconnected devices. This decentralized architecture enhances network resilience and coverage.
Key Concepts:
- Self-Healing: If one node fails, the network can automatically reroute data through other nodes, ensuring continuous connectivity.
- Scalability: New nodes can be added to the network without significant reconfiguration, making it easy to expand coverage.
- Redundancy: Multiple paths for data transmission reduce the risk of network failure and improve reliability.
Example:
Imagine a large campus where Wi-Fi coverage is needed in every building. Instead of deploying a central access point for each building, a mesh network can be set up where each building's access point connects to neighboring buildings. If one building's access point fails, devices in that building can still connect through neighboring access points, ensuring uninterrupted service.
2. Load Balancing and Band Steering
Load Balancing and Band Steering are techniques used to optimize the performance of wireless networks by distributing client devices across available channels and frequency bands.
Key Concepts:
- Load Balancing: Distributes client connections across multiple access points to prevent overloading any single AP and to ensure even distribution of network traffic.
- Band Steering: Encourages client devices to connect to the less congested 5 GHz band, if supported, to improve overall network performance and reduce interference.
Example:
Consider a busy office where many employees are using Wi-Fi. Load balancing ensures that no single access point becomes overwhelmed with connections, distributing users across multiple APs. Band steering then directs devices capable of 5 GHz connectivity to that band, freeing up the congested 2.4 GHz band for devices that cannot operate on 5 GHz, thereby improving overall network speed and reliability.
