A network architect is designing a wireless network for a large office building. The design includes multiple access points (APs) and aims to provide seamless roaming between different parts of the building. Which of the following wireless concepts is crucial for achieving this seamless roaming capability?
- AChannel bonding
- BSSID broadcast suppression
- CPower over Ethernet (PoE)
- DRadio Resource Management (RRM)
Show answer & explanationAnswer & explanation
Correct answer: D. Radio Resource Management (RRM)
Radio Resource Management (RRM) is a feature, often found in wireless LAN controllers (WLCs), that dynamically adjusts AP power levels and channel assignments to optimize coverage and minimize interference, which is crucial for seamless client roaming.
Why the other options are wrong
- A. Channel bonding combines multiple channels to increase bandwidth, not directly for seamless roaming.
- B. SSID broadcast suppression hides the network name, which is a security measure and doesn't facilitate roaming.
- C. PoE provides power to APs over Ethernet cables, simplifying deployment but not directly related to roaming functionality.
Wireless Roaming
Wireless roaming allows a client device to maintain network connectivity as it moves between the coverage areas of different access points within the same network.
- Requires overlapping AP coverage.
- Often managed by wireless LAN controllers or intelligent APs.
- Factors like signal strength and interference influence roaming decisions.
