Which device would a WLAN administrator install between an AP and the network to maximize bandwidth available to indoor users?

• A. A VPN concentrator.
• B. A bandwidth control unit (BCU).
• C. A router with NAT.
• D. A coax-to-Ethernet adapter.

Answer: (B)

Maximizing the bandwidth available to indoor WLAN users hinges on controlling and prioritizing how network capacity is used as wireless traffic moves toward the core. A Bandwidth Control Unit placed between the access points and the rest of the network provides traffic shaping and quality-of-service policies that allocate uplink capacity, prevent congestion, and smooth bursts. This directly improves the usable throughput for indoor clients by ensuring their traffic gets the necessary share of bandwidth. The other options address different functions: a VPN concentrator handles secure remote access rather than increasing local bandwidth; a router with NAT adds processing overhead and doesn’t inherently boost capacity; and a coax-to-Ethernet adapter is not relevant for enhancing WLAN bandwidth.
