8 weeks · About 6 hours per week
Describe Wireless Networking Features and Functions & Define Basic RF Characteristics
Map the CWSS exam blueprint into a personal tracker, weighting Domain 2 at 30% and Domain 3 at 30% of total study time.
Define and compute the core RF quantities used throughout wireless work: wavelength, frequency, amplitude, and phase, including the inverse relationship between frequency and wavelength.
Convert between dBm, mW, and dB gains/losses without a calculator for the common values (0, 3, 10, 20 dBm and 3, 10 dB).
Explain how free-space path loss scales with frequency and distance, and state why 5 GHz attenuates faster than 2.4 GHz at equal distance.
Set up a study log template that records hours, topics, and self-quiz scores for all eight weeks.
Your checkpoint
A one-page RF math cheat sheet plus a completed 20-question self-quiz on units and dB conversions, scored and logged.
Describe Wireless Networking Features and Functions
Describe the 802.11 PHY amendments (a/b/g/n/ac/ax) and identify which band, channel width, and modulation each supports.
Diagram the 2.4 GHz and 5 GHz channel plans, marking the three non-overlapping 2.4 GHz channels and the DFS ranges in 5 GHz.
Explain OFDM, DSSS, and OFDMA at a conceptual level and match each to the amendments that use it.
Summarize CSMA/CA and the RTS/CTS exchange, and explain how hidden nodes cause collisions.
Compare 20, 40, 80, and 160 MHz channel widths in terms of throughput gain versus co-channel interference risk.
Your checkpoint
A channel-plan diagram for a two-floor building showing 2.4 GHz and 5 GHz assignments with non-overlapping channels annotated.
Describe Wireless Networking Features and Functions
Explain the 802.11 frame types (management, control, data) and the role of beacons, probes, and association requests.
Trace the full client join sequence from probe to 802.1X/EAP authentication to 4-way handshake to DHCP.
Differentiate WPA2-Personal, WPA2-Enterprise, WPA3-SAE, and WPA3-Enterprise by credential model and key exchange.
Describe roaming mechanics including 802.11k, 802.11v, and 802.11r and explain what each improves.
Identify common causes of poor roaming such as sticky clients and mismatched power settings.
Your checkpoint
A sequenced join-and-roam walkthrough written from memory, checked against notes, with every frame type labeled.
Describe Wireless Networking Features and Functions & Identify Wireless Hardware and Software
Classify access point categories (standalone, controller-based, cloud-managed) and state the tradeoffs of each for a mid-size organization.
Explain PoE standards (802.3af, at, bt) and calculate the power budget for a given AP count and per-AP draw.
Describe antenna types (omnidirectional, directional, patch, Yagi) and match each to a coverage scenario such as a warehouse aisle or outdoor bridge.
Interpret antenna gain, EIRP, and regulatory limits, and explain how cable loss reduces EIRP.
Compare WLC deployment models and describe how CAPWAP tunnels carry control and data traffic.
Your checkpoint
A hardware selection table for a sample 40-AP deployment listing AP model class, PoE class, antenna type, and calculated EIRP per area.
Identify Wireless Hardware and Software
Perform a manual site survey walkthrough: define requirements, take spectrum readings, place APs, and validate coverage.
Interpret a heat map and identify coverage holes, co-channel interference zones, and over-power cells.
Explain the difference between a predictive, passive, and active survey and when each is appropriate.
Describe spectrum analysis output and distinguish Wi-Fi interference from non-Wi-Fi interferers such as microwave ovens and cordless phones.
List the software and tool categories used in wireless work: survey tools, spectrum analyzers, protocol analyzers, and controller dashboards.
Your checkpoint
A mock survey report for a single floor with a coverage assessment, three identified problems, and remediation recommendations.
Understand Organizational Goals & Identify Wireless Hardware and Software
Translate business requirements (guest access, BYOD, IoT, PCI scope) into wireless design constraints.
Explain how capacity planning differs from coverage planning and estimate AP count from user density and per-client throughput targets.
Describe how a wireless deployment supports organizational goals such as uptime, security posture, and cost control.
Draft a budget outline covering hardware, licensing, installation, and ongoing support for a small deployment.
Identify stakeholders in a wireless project and the questions to ask each during requirements gathering.
Your checkpoint
A requirements document for a fictional organization capturing user density, applications, security needs, budget range, and success metrics.
Define Basic RF Characteristics & Describe Wireless Networking Features and Functions & Identify Wireless Hardware and Software
Re-derive the RF link budget for a point-to-point bridge including transmit power, antenna gain, cable loss, and path loss.
Reconstruct the full client onboarding and roaming flow and the security handshakes without notes.
Review all hardware and software categories and state one selection criterion for each.
Complete a timed 60-question mixed-domain practice set and tag every miss by domain.
Rewrite weak-topic notes into concise one-line rules for rapid recall.
Your checkpoint
A timed practice exam score with a domain-by-domain error breakdown and a prioritized list of the five weakest topics.
Understand Organizational Goals & Describe Wireless Networking Features and Functions & Define Basic RF Characteristics
Re-study the five weakest topics identified in week 7 and re-quiz each until scoring above 80%.
Practice explaining a full wireless design decision to a non-technical stakeholder in under three minutes.
Review organizational-goal scenarios and practice picking the design that best matches a stated business constraint.
Run a second timed 60-question practice set and compare the score against week 7.

Milestones
Week 2: Score 80% or higher on a 20-question quiz covering RF units, dB math, and 802.11 PHY/channel fundamentals; if below, repeat week 1 math drills before continuing.
Week 4: Explain the client join and roam sequence end to end without notes, and correctly answer 15 of 15 questions on frame types and WPA/WPA3 security models.
Week 6: Produce a requirements document and a hardware selection table that are internally consistent: AP count, PoE budget, and EIRP all match the stated user density and coverage area.
Week 8: Achieve 85% or higher on the final timed practice set with no domain scoring below 70%, and complete the one-page review sheet from memory before checking notes.
