​Core Features & Technical Specifications​

The ​​CBW140AC-K​​ is a Cisco Business Wireless access point optimized for South Korean small businesses requiring reliable, high-performance Wi-Fi with local compliance. Key specs include:

  • ​Dual-band 802.11ac Wave 2​​ support, delivering up to ​​1.267 Gbps​​ (867 Mbps on 5 GHz, 400 Mbps on 2.4 GHz).
  • ​2×2 MU-MIMO​​ for efficient connectivity in dense environments like cafes or co-working spaces.
  • ​PoE+ (802.3at) powered​​ with ​​24V passive PoE backup​​, compatible with Korean voltage standards (220V).
  • ​KC Certification​​ for electromagnetic compliance, ensuring adherence to South Korea’s regulatory requirements.
  • ​Integrated security​​ via Cisco’s Security Connector, offering basic threat detection and WPA3 encryption.

​Critical User Questions Answered​

​Q: How does the CBW140AC-K handle high-density environments like retail stores?​

The ​​MU-MIMO technology​​ allows simultaneous data streaming to multiple devices, supporting ​​40–60 concurrent users​​ in typical scenarios. For bandwidth-heavy applications (e.g., live streaming), limit to 20–25 devices per AP to maintain performance.


​Q: Is a separate wireless controller needed for management?​

No. The AP operates in ​​standalone mode​​ or uses Cisco’s ​​Mobility Express software​​ (hosted on another CBW AP) as a virtual controller. This eliminates hardware costs, ideal for small deployments like clinics or boutiques.


​Q: Can it prioritize critical traffic like VoIP in noisy RF environments?​

Yes. Use the ​​QoS presets​​ to prioritize VoIP (e.g., KakaoTalk) or video conferencing traffic. For example, assign “Gold” priority to Microsoft Teams to reduce jitter during calls.


​Ideal Deployment Scenarios in South Korea​

  • ​Retail​​: Deploy in stores to support guest Wi-Fi, NFC payment systems, and inventory management tablets.
  • ​Education​​: Cover small classrooms with wall-mounted APs, isolating student and administrative traffic via VLANs.
  • ​Hospitality​​: Provide seamless roaming for guests across floors while securing back-of-house operations.

​Observations from Real-World Use​

In a Seoul café deployment, the ​​KC-certified design​​ simplified compliance audits, while the ​​24V passive PoE​​ ensured uptime during power fluctuations common in older buildings. The lack of Wi-Fi 6 support limits future-proofing, but for sub-100 Mbps internet plans typical in Korean SMBs, its performance remains solid. For larger venues, pairing multiple units with Mobility Express creates a cost-effective mesh—proving that localized compliance and simplicity often outweigh raw specs in regulated markets.
