How to choose between Auto (high band preferred) and dedicated radio band with smart mesh?

Zyxel_Bella

When configuring a mesh network, particularly with Smart Mesh technology, understanding the difference between 'Auto (high band preferred)' and dedicated radio band settings is crucial for network stability. These settings determine how your network manages its wireless connections, especially in environments with varying wireless signal strengths and interferences.

Topology and Scenario

Gateway --- Switch --- Root AP ))) ((( Repeater AP ))) Clients

Key Setting: 'Auto (high band preferred)' versus a fixed radio band.

Configuration

1. Go to Access points > AP detail page > Smart mesh > Band

2. Set Band Mode:

The 'Auto (high band preferred)' mode in a Smart Mesh network actively seeks the best possible connection by analyzing factors like RSSI and channel utilization. It dynamically switches between bands (high band like 5GHz preferred) to optimize connection quality, which can lead to temporary disconnects as the system searches for a more optimal link when mesh connections on 2.4GHz.

Fixed radio band (either 2.4GHz or 5GHz) disables this dynamic switching. The network remains on the selected band, providing a more stable connection but potentially missing out on a better connection that another band might offer at different times or in different areas of the coverage zone.

Verification

Check the smart mesh build in the band you setup.

Noted

Auto Mode Challenges: The 'Auto (high band preferred)' mode may cause frequent reconnections in fluctuating environments.

Fixed Band Stability: Choosing a fixed band can provide more consistent connectivity but may not always be optimal.

Observe Connection Stability: after setting, check for reduced disconnects.

Adjustments and Monitoring: Regular monitoring and adjustments may be required based on environmental factors and usage patterns.
