Introduction

Band Steering is a solution ensures that clients are connected to the best radio. Dual Band supported Gateway can transmit SSIDs in both 2.4GHz and 5GHz frequency band. Band Steering solution does upgrade steering ( from 2.4 GHz to 5 GHz) and downgrade steering (5 GHz to 2.4 GHz) which allows optimal utilization of both bands. The Steering of the Wireless clients are based on the following parameter,

• Wireless Client Capacity
• Signal Strength in current and target band
• Bandwidth Utilization in current and target band
• Steering History
• Wireless Client Activity (Inactive Client/ Active Client)

The purpose of Band Steering feature is to maintain Wireless Clients in band best suited to them. For instance, a 5GHz capable client would be maintained in faster & wider-channeled 5GHz band but if the Received Signal Strength is lesser than the threshold value, the Client is moved to a wider-range 2.4GHz band.

Design Considerations

• Decision Overview

< Describe the system design in broad terms . Consider benefits, costs and schedule and technical risks. Describe how the proposed solution aligns with the enterprise architecture. >The most basic prerequisite of Band Steering is both the 2.4GHz and the 5GHz frequency band must have the same SSID and passphrase.

• Other Considerations (DAR)

...

< Identify output interfaces, function call protocol, and the nature of the data structures passed across the interface. >
