Wi-Fi Assessment & Design
Whether for a single location or multiple unique sites, our Wi-Fi Assessment & Design services are always delivered in a methodical and proven approach, following industry best practices. Our personnel leverage industry-best tools and provide all customers with top-notch results throughout all engagement phases, ensuring a trusted, enterprise-class Wi-Fi infrastructure.
Needs Assessment
Trestle Networks will work closely with the customer to identify all the business and technical requirements, through intensive face-to-face data collection and data analysis. We will focus on topics including:
- Identifying in-scope and out-of-scope locations
- Recent operational issues with existing Wi-Fi infrastructure, if applicable
- Coverage and capacity needs
- Application visibility, intrusion prevention and other security features
- Aesthetic requirements for AP installation (enclosures, placement, other)
- PCI DSS 3.2, HIPAA other compliance requirements
- Manageability, scalability and modularity
- Anticipated 6 to 12-month site changes that may impact any current WiFi analysis or design recommendation
Pre-Deployment Site Survey
After completion of the needs assessment, Trestle Networks will visit each in-scope customer site and perform an initial inspection of the environment. Our work will include:
- RF spectrum analysis of the customer site(s) including the detection and measurement of RF interference from microwave equipment, neighboring and legacy Wi-Fi infrastructure, Bluetooth devices and other radio sources. This is essential to any successful Wi-Fi deployment. For any interference sources identified, Trestle Networks will work with each customer in addressing any interference sources prior to proceeding with Wi-Fi survey activities.
- Validation of the site dimensions (in feet or meters) against each customer-provided floor plan or – at additional cost – Trestle Networks-created floor plan.
- Identification of existing Wi-Fi infrastructure and all AP placement (if applicable)
- Identification of RF obstacles and site building materials for use in predictive planning
- If there is no existing Wi-Fi infrastructure to utilize in the survey our team will perform a combination of initial predictive planning of APs placement and “AP on a stick” Wi-Fi validation. This task will further ensure the accuracy of our Wi-Fi design based on the precise RF attenuation characteristics of the site.
Predictive Design
Trestle Networks will use our many years of Wi-Fi experience and state-of-the-art predictive planning tools to deliver a Wi-Fi architecture (or re-design an existing environment) meeting each customer’s requirements with the flexibility/modularity to evolve along as per-site requirements change. Our work will include:
- Wi-Fi industry best practices and platform-specific AP model recommendations (existing, new and refresh for placement) based on customer’s feature, security and performance requirements
- Design for client coverage, density, application types, application throughput and device types (including guest and PCI DSS CDE in-scope devices)
- CoS and QoS settings recommendations, based on customer’s traffic types, WAN speeds and other factor
- 5GHz and 2.4GHz cell sizing, channel planning and addressing of 802.11 legacy standards (including setting minimum data rates)
- AP placement onto customer-provided floor plans or Trestle-created floor plans (extra charge required for floor plan creation), including multi-level environment
- Per-AP client capacity planning, based on airtime consumption, required per-client bandwidth and application traffic types
If this is a “greenfield” Wi-Fi installation or a Wi-Fi refresh, we will happily offer a design using our preferred vendors as part of our managed services offering. However, our team also has the experience to offer design recommendations that suit many other vendor’s equipment.
Deployment & Active Site Survey
Trestle Networks will collaborate with the customer and any of their 3rd party vendors to deploy Wi-Fi design (Trestle Networks-provided APs or 3rd-party APs) and then perform extensive, hands-on site survey to verify all Wi-Fi features and functionality. Our on-site work will include:
- Verification of RSSI and SNR at points across the entire coverage area
- TCP and UDP throughput testing during off-peak and peak client density
- Client splash page loading and authentication verification for all SSIDs
- Client roaming between APs
- Redundant AP coverage verification for 2.4GHz and 5GHz radios
- As-necessary design & configuration adjustments based on active site survey results
