Types of Load Balancing in Aruba Wireless APs
Band steering
Band steering is a crucial load balancing technique used in Aruba Wireless APs to optimize network performance. This method encourages dual-band capable clients to connect to the less congested 5 GHz band, reducing traffic on the often overcrowded 2.4 GHz band.
| Feature | 2.4 GHz Band | 5 GHz Band |
|---|---|---|
| Range | Longer | Shorter |
| Speed | Slower | Faster |
| Congestion | Higher | Lower |
Benefits of band steering include:

Client match
Client match is an advanced load balancing feature that intelligently distributes clients across multiple APs. It ensures that each client connects to the most suitable AP based on various factors:
- Signal strength
- AP capacity
- Channel utilization
This technology helps prevent situations where clients stick to a distant AP despite the presence of closer, less congested options.
Airtime fairness
Airtime fairness is a load balancing mechanism that allocates equal airtime to all connected clients, regardless of their individual connection speeds. This approach prevents slower devices from monopolizing network resources and ensures a fair distribution of bandwidth.
Key advantages:
- Improved overall network efficiency
- Enhanced user experience for all clients
- Mitigation of the “slow client problem”
Adaptive Radio Management (ARM)
ARM is a comprehensive load balancing solution that automatically optimizes radio settings to maintain optimal network performance. It continuously monitors and adjusts various parameters, including:
- Channel selection
- Transmit power levels
- Client connections
ARM’s dynamic nature allows it to respond to changing network conditions in real-time, ensuring consistent performance and reliability across the wireless infrastructure.
Implementing Load Balancing in Aruba Networks
Configuration steps
Implementing load balancing in Aruba Networks involves a series of configuration steps:
