Certified Wireless Network Administrator (CWNA-109) – Complete Exam Information

Who Should Take the CWNA-109?

The CWNA-109 is the right exam for anyone working with or moving into enterprise wireless networking. Here’s who benefits most:

• Network Administrators and IT Generalists who manage wireless infrastructure in schools, hospitals, or corporate environments will find the CWNA validates skills they use every day — and opens doors to higher-level CWNP certifications.
• Help Desk and Field Technicians looking to move into network roles use the CWNA to build a solid foundation in Wi-Fi fundamentals, from channel planning to client troubleshooting.
• Network Engineers who already work with wired infrastructure but want to add wireless expertise to their skill set. The CWNA is the entry point to CWNP’s professional-level certifications like CWSP, CWDP, and CWAP. If you are looking to map out your long-term goals, review the full CWNP certification path.
• Wi-Fi Sales Engineers and Solutions Architects who need to speak fluently about 802.11 standards, WLAN design considerations, and security options with enterprise customers.
• Recent IT Graduates who want a vendor-neutral wireless credential that demonstrates real hands-on knowledge to employers — not just familiarity with one vendor’s product line.

Experience-wise, CWNP recommends at least one year working with wireless LAN technologies, along with basic knowledge of networking (routers, switches, cabling) and TCP/IP fundamentals.

CWNA-109 Exam Structure

The CWNA-109 uses standard multiple choice and multiple answer questions — no labs or simulations. This makes solid practice with scenario-based questions especially important, since the exam tests your ability to apply knowledge, not just recall it.

CWNA-109 Exam Domains and Objectives

The following domains come directly from the official CWNA-109 exam objectives document published by CWNP.

Domain 1: Radio Frequency (RF) Technologies – 15%

This domain covers the physics and math behind wireless signals — the foundation everything else builds on.

• RF signal characteristics: wavelength, frequency, amplitude, phase, and sine waves
• RF propagation behaviors: reflection, refraction, diffraction, scattering, multipath, and interference
• RF math: watts, milliwatts, decibels (dB), dBm, dBi, SNR, RSSI, EIRP, and FSPL calculations
• Antenna concepts: omni-directional, semi-directional, highly directional antennas; beamwidth; polarization; MIMO and antenna diversity
• RF accessories: cables, connectors, lightning arrestors, enclosures, and mounting considerations

Candidates often struggle with RF math, especially dBm-to-milliwatt conversions and EIRP calculations. Practice these until they’re second nature.

Domain 2: WLAN Regulations and Standards – 20%

This is one of the largest domains and covers the full 802.11 standard family along with regulatory requirements.

• Industry organizations: IEEE, Wi-Fi Alliance, IETF, and regulatory agencies
• 802.11 PHY standards: DSSS (802.11), HR-DSSS (802.11b), OFDM (802.11a), ERP (802.11g), Wi-Fi 4/HT (802.11n), Wi-Fi 5/VHT (802.11ac), Wi-Fi 6/HE (802.11ax), and Wi-Fi 6E (6 GHz)
• Spread spectrum and modulation: DSSS, OFDM, OFDMA, BPSK, QPSK, QAM (16 through 1024)
• Channel planning: primary channels, overlapping vs. non-overlapping channels, OBSS, throughput vs. data rate
• Regulatory domain requirements: frequency bands, power constraints, DFS, TPC, indoor/outdoor rules
• Use case scenarios: WLAN (BSS/ESS), wireless bridging, mesh, and peer-to-peer

Wi-Fi 6 and 6E content has grown in importance since the CWNA-109 release — spend meaningful time here.

Domain 3: WLAN Protocols and Devices – 20%

This domain digs into how 802.11 networks actually work at the protocol level.

• Service set components: STAs, BSS, SSID, BSSID, ESS, IBSS, Distribution System
• MAC and PHY terminology: MSDU, MPDU, PSDU, PPDU, A-MSDU, A-MPDU, PHY preamble
• 802.11 frame types and format: management, control, and data frames; MAC addressing
• Connection process: active/passive scanning, authentication, association, BSS selection, hidden SSIDs
• Channel access methods: DCF, EDCA, RTS/CTS, CTS-to-Self, NAV, interframe spaces (SIFS, DIFS, EIFS, AIFS)
• MAC operations: roaming, power save modes, protection mechanisms
• WLAN devices: access points, WLAN controllers, wireless network management systems, client devices

The channel access and frame exchange sections trip up many candidates — work through practice questions until the sequence feels natural.

Domain 4: WLAN Network Architecture and Design Concepts – 15%

This domain covers real-world deployment and design decisions.

• Power over Ethernet (PoE): PSE and PD types, midspan/endpoint PSEs, power classes, power budgets
• WLAN architectures: centralized vs. distributed data forwarding, control/management/data planes, scalability and availability, tunneling, QoS, and VLANs
• Design considerations: coverage, roaming, throughput, voice and video requirements, high-density deployments, guest access, BYOD, and legacy 802.11 device support
• Proprietary features: AirTime Fairness, band steering, dynamic power and channel management
• Supporting network services: DHCP, DNS, NTP/SNTP, VLANs, RADIUS/LDAP authentication, ACLs, wired capacity requirements

Domain 5: WLAN Network Security – 10%

This domain is smaller in percentage but critical for real-world practice.

• Weak security to avoid: WEP, shared key authentication, SSID hiding, MAC filtering, TKIP-based WPA/WPA2
• Effective enterprise security: AES encryption, WPA2-Personal (PSK limitations), WPA2-Enterprise with 802.1X and RADIUS
• WPA3 and OWE: security enhancements over WPA2, SAE (Simultaneous Authentication of Equals), Opportunistic Wireless Encryption for public networks
• Security tools and options: access control, protected management frames, fast secure roaming, WIPS/rogue AP detection, protocol and spectrum analyzers, secure management protocols

Domain 6: RF Validation and WLAN Remediation – 20%

This domain covers post-deployment validation and troubleshooting — skills that separate good wireless admins from great ones.

• Post-implementation surveys: verifying coverage, throughput, roaming, and connectivity against design requirements
• RF interference identification: co-channel contention, overlapping channels, non-802.11 interference sources, mitigation options
• Application testing: VoIP testing, real-time application testing, throughput testing, network and service availability checks
• Validation tools: throughput testers, wireless validation software, survey tools, protocol analyzers, spectrum analyzers
• Troubleshooting common issues: insufficient throughput, PoE budget problems, DHCP/DNS/NTP failures, security configuration mismatches, hidden node issues, and RF interference resolution using spectrum analyzers

CWNA-109 Cost and Eligibility

The CWNA-109 exam costs $274.99 USD and is delivered at Prometric Testing Centers worldwide or via CWNP’s approved remote proctoring option.

There are no formal prerequisites — you don’t need to hold the CWTS or CWSS certification first, though CWNP recommends it. Practically speaking, you should have at least one year of hands-on experience with wireless LANs and solid foundational networking knowledge before attempting the exam.

The CWNA certification is valid for three years. To recertify, pass one of the professional-level CWNP exams (CWSP, CWDP, or CWAP) before your CWNA expires — this renews the CWNA for another three years. Or simply retake the current CWNA exam.

Note: The CWNA-109 is available through December 31, 2026. The CWNA-110 is scheduled for release in September 2026.

Why CWNA-109 Certification Matters in 2026

Wi-Fi isn’t optional infrastructure anymore. It’s load-bearing. Hospitals, warehouses, universities, corporate campuses, and retail environments all depend on reliable, high-performance wireless networks — and the people who design, manage, and fix those networks need proven credentials. To understand the full value of this track to employers, explore the benefits of CWNP certification and see if CWNP certification is worth it for your specific career goals.

The CWNA is the foundational enterprise Wi-Fi certification in the CWNP program, and it’s widely recognized as the most technically rigorous vendor-neutral wireless credential available. Unlike vendor-specific certifications that lock you into one ecosystem, the CWNA applies to any enterprise WLAN environment.

In terms of career impact, CWNA holders typically work as network administrators, wireless engineers, systems engineers, and IT infrastructure specialists. According to salary data on PayScale and Glassdoor, wireless network engineers in the US earn between $70,000 and $110,000 annually depending on experience and location, with CWNP certifications consistently listed among the credentials employers look for in job postings.

The CWNA also serves as a required stepping stone to the higher CWNP certifications — CWSP (security), CWDP (design), and CWAP (analysis) — as well as the expert-level CWNE. So passing CWNA-109 isn’t just a credential win; it’s the foundation for a longer career path in wireless networking.

With Wi-Fi 6E deployment accelerating and Wi-Fi 7 on the horizon, organizations need wireless administrators who understand the full technology stack — from RF physics to 802.11ax architecture to enterprise security. The CWNA-109 covers all of it.

Proven Study Strategies for CWNA-109 Success

• Start with the official exam objectives: Download the CWNA-109 objectives PDF from CWNP and use it as your study roadmap. Everything on the exam comes from that document.
• Follow a 6-week study plan: Here’s a realistic timeline:

1. Week 1: RF Technologies and antenna concepts (Domain 1)
2. Week 2: WLAN Regulations and Standards — 802.11 PHY standards, modulation, channels (Domain 2)
3. Week 3: WLAN Protocols and Devices — frame types, channel access, connection process (Domain 3)
4. Week 4: Network Architecture and Design + Network Security (Domains 4 and 5)
5. Week 5: RF Validation and troubleshooting (Domain 6), then review weak areas
6. Week 6: Full practice exams, timed simulation, review explanations for wrong answers

• Use PassITExams practice tests as your daily check: After studying each domain, take a targeted practice test on that topic before moving on. This locks in knowledge faster than reviewing notes alone.
• Don’t skip the RF math: The dB rules of 3 and 10, EIRP calculations, and FSPL concepts show up directly in exam questions. Practice these until they’re automatic.
• Get hands-on time with real gear if you can. Even basic experience configuring an AP, running a wireless scan, or watching a protocol analyzer helps the theoretical concepts click.
• Learn to read azimuth and elevation charts. Antenna coverage pattern questions appear on the exam, and candidates who’ve never looked at these charts before often get them wrong.
• Time yourself on practice exams. You have 90 minutes for 60 questions — that’s 90 seconds per question. Practice at that pace so you’re not rushing on test day.
• Focus extra attention on Domains 2, 3, and 6 — each carries 20% of the exam weight. Together they make up 60% of your score.
