This curriculum spans the technical and operational rigor of a multi-workshop wireless deployment program, covering the same scope of tasks as an on-site advisory engagement for enterprise Wi-Fi rollout, from initial site assessment to ongoing maintenance.

Module 1: Site Survey and RF Environment Assessment

  • Conducting passive and active site surveys using spectrum analyzers to identify existing Wi-Fi networks and non-Wi-Fi interference sources such as microwaves or Bluetooth devices.
  • Determining optimal access point placement based on building materials, physical obstructions, and expected user density.
  • Selecting appropriate survey tools (e.g., Ekahau, NetSpot, or inSSIDer) based on client environment complexity and budget constraints.
  • Mapping channel utilization across 2.4 GHz and 5 GHz bands to avoid co-channel interference in dense deployments.
  • Documenting signal-to-noise ratio (SNR) thresholds at various locations to ensure minimum connectivity standards are met.
  • Adjusting transmit power settings on access points to balance coverage and capacity while minimizing overlap.

Module 2: Access Point Selection and Hardware Deployment

  • Evaluating ceiling-mount versus wall-mount access points based on physical layout and coverage requirements.
  • Verifying PoE (Power over Ethernet) compatibility between switches and access points, including IEEE 802.3af/at/bt standards.
  • Planning cable runs and conduit placement for permanent installations, ensuring compliance with local fire and safety codes.
  • Configuring standalone versus cloud-managed APs based on organizational IT staffing and remote management needs.
  • Labeling and documenting each AP with location, MAC address, and VLAN assignment for operational tracking.
  • Testing AP firmware versions pre-deployment to avoid known bugs or compatibility issues with existing infrastructure.

Module 3: Wireless Network Configuration and SSID Design

  • Segmenting SSIDs by function (e.g., corporate, guest, IoT) and assigning appropriate VLANs for traffic isolation.
  • Configuring band steering and dual-band broadcasting to encourage client devices to use 5 GHz where available.
  • Setting appropriate beacon intervals and DTIM periods based on device types, especially for battery-powered clients.
  • Disabling legacy 802.11b rates in high-density environments to improve airtime efficiency.
  • Implementing multiple BSSIDs per AP when required for network segmentation without additional hardware.
  • Adjusting RTS/CTS thresholds to mitigate hidden node issues in large or obstructed coverage areas.

Module 4: Authentication, Security, and Policy Enforcement

  • Deploying WPA2-Enterprise with 802.1X/EAP-TLS instead of PSK in corporate environments to enable individual user accountability.
  • Integrating wireless authentication with existing directory services (e.g., Active Directory via RADIUS) and validating certificate trust chains.
  • Configuring captive portals for guest access with time-limited credentials and bandwidth throttling.
  • Enabling management frame protection (802.11w) to prevent deauthentication attacks on client sessions.
  • Disabling WPS due to known security vulnerabilities, even if requested by end users for convenience.
  • Implementing MAC address filtering only as a supplemental control, not as a primary security measure.

Module 5: DHCP, DNS, and IP Addressing Integration

  • Ensuring sufficient DHCP scope size and lease duration to support peak wireless client counts without exhaustion.
  • Configuring DHCP option 43 and 60 to enable plug-and-play provisioning for vendor-specific access points.
  • Validating DNS resolution from wireless clients, especially for internal resources and authentication servers.
  • Implementing IP helper addresses on VLAN interfaces to forward DHCP requests to centralized servers.
  • Reserving static IP addresses for critical APs and wireless controllers to simplify management and monitoring.
  • Monitoring for rogue DHCP servers on the wireless network that could disrupt client connectivity.

Module 6: Wireless Performance Monitoring and Troubleshooting

  • Using packet capture tools (e.g., Wireshark with wireless adapters) to diagnose retransmission and latency issues.
  • Interpreting airtime utilization metrics to identify over-saturated channels or malfunctioning clients.
  • Responding to user complaints by replicating issues with test devices and checking historical performance logs.
  • Identifying sticky clients that fail to roam by analyzing signal thresholds and AP load balancing settings.
  • Checking for asymmetric uplink/downlink performance caused by misconfigured QoS or bandwidth shaping.
  • Validating roaming behavior across APs by walking test paths and monitoring 802.11r/k/v handoff events.

Module 7: Guest Network and BYOD Policy Implementation

  • Isolating guest traffic at Layer 3 using dedicated VLANs and firewall rules to prevent access to internal resources.
  • Configuring splash pages with acceptable use policies and integrating with social or email registration where required.
  • Enforcing bandwidth limits per guest session to prevent network abuse and ensure fair usage.
  • Implementing device registration workflows for BYOD, including certificate enrollment and MDM onboarding.
  • Blocking high-risk application traffic (e.g., peer-to-peer, remote desktop) on guest and BYOD SSIDs via DPI or firewall policies.
  • Setting session timeouts and re-authentication intervals for guest users to maintain security hygiene.

Module 8: Documentation, Change Control, and Ongoing Maintenance

  • Maintaining up-to-date network diagrams that include AP locations, channel assignments, and VLAN mappings.
  • Logging configuration changes to wireless infrastructure in a change management system with rollback plans.
  • Scheduling regular firmware updates for APs and controllers, including testing in staging environments first.
  • Conducting periodic site validation to reassess coverage after physical changes (e.g., new walls, furniture).
  • Archiving survey data and performance baselines to support future troubleshooting and expansion.
  • Coordinating with facilities and security teams when deploying APs in restricted or high-security areas.
