CWSS study plan

CWSS · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

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.

Week 2

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.

Week 3

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.

Week 4

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.

Week 5

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.

Week 6

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.

Week 7

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.

Week 8

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.

  • Finalize a one-page pre-exam review sheet covering RF math, channel plans, security handshakes, and survey workflow.

Your checkpoint

A second timed practice score showing improvement over week 7, plus the completed one-page pre-exam review sheet.

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.
