About

The CWNA is CWNP's Associate-level foundation certification, validating expertise in wireless LAN administration, RF fundamentals, and 802.11 standards. Launched in 1999 and continuously updated (CWNA-109 released in 2023), it is the mandatory prerequisite for all CWNP professional certifications. It is held by network administrators, engineers, and support professionals responsible for deploying, securing, and troubleshooting enterprise and SMB wireless networks. The exam covers practical skills across RF theory, regulatory compliance, security baselines, and site survey methodologies.

Domain context — Networking / Wireless

Wireless networking is a specialized segment of enterprise networking focused on radio-frequency (RF) transmission, 802.11 standards compliance, WLAN infrastructure design, and integration with wired networks. It encompasses radio propagation, antenna theory, regulatory frameworks, security protocols, and troubleshooting methodologies.

Topics covered

The CWNA-109 exam blueprint covers six primary knowledge domains with the following weight distribution:

• Radio Frequency (RF) Technologies (15%) — Wavelength, frequency, modulation, propagation, interference, fading, path loss, and antenna fundamentals; understanding RF behavior to predict coverage and optimize network performance.
• WLAN Regulations and Standards (20%) — FCC, ETSI, and ISED frequency allocations; regulatory compliance; power limits; channel planning in 2.4 GHz and 5 GHz bands; Wi-Fi standards evolution.
• WLAN Protocols and Devices (20%) — 802.11 frame structure; MAC layer operations; QoS mechanisms; access points, clients, bridges, and repeaters; roaming behavior and authentication states.
• WLAN Network Architecture and Design Concepts (15%) — Network topology, site survey planning, AP placement, capacity planning, scalability, failover mechanisms, and integration with wired infrastructure.
• WLAN Network Security (10%) — Authentication methods (802.1X, Open, Shared Key, WPA, WPA2, WPA3); encryption (TKIP, CCMP, GCMP); threats and mitigation; guest network segmentation.
• RF Validation and Remediation (20%) — Spectrum analysis, interference identification, troubleshooting poor coverage, documenting site surveys, validating post-deployment performance using tools like Wi-Fi analyzers and spectrum analyzers.
