Predictive Wi-Fi Survey

DW Wi-Fi offers a predictive survey to provide the customer with a prediction of the number of access points and suggested locations to provide the required Wi-Fi reception of their site. Scaled floor plans are required from the customer. These are imported into modelling software. The drawing are scaled and then annotated.

This process requires various mediums throughout the site (walls, lift shafts, etc) are identified in terms of their material and thickness and assigned a Wi-Fi signal loss. This enables the modelling software to predict the effects the mediums have on Wi-Fi signal in terms of reflection, refraction and absorption. The floor plans can be populated by virtual access points. The modelling software then processes the information input to produce a set of visualisations (heat maps).

A survey report containing a selection of visualisations together with a bespoke document detailing the proposed solution consisting of the make and model of Wi-Fi access point together with any ancillary components such as antennas, PoE+ power injectors.

Wi-Fi Site Survey

DW WiFi offers a ‘live’ on-site survey using a mobile battery powered Wi-Fi access point. Heat mapping software is used in conjunction with your scaled floor plans to take Wi-Fi measurements using a laptop at regular intervals throughout your site.

The mobile access point can be located in optimum locations as the discretion of the Wi-Fi engineer. The area in range of the access point is then surveyed. The process is repeated having moved the mobile access point to the next location until the survey of the entire site is complete. The survey software is then able to combine the results for each access point location.

In addition, spectrum analysis of the Wi-Fi bands is completed during the visit to monitor for any sources of interference. Comprehensive documentation is provided detailing the proposed solution including photographs of the proposed access point locations in a bespoke report.

Also provided is a separate survey report containing a selection of visualisations depicting Wi-Fi signal levels, Wi-Fi coverage etc commonly known as ‘heat maps’.

Wi-Fi Verification Survey

DW WiFi offers a ‘live’ on-site survey of an existing Wi-Fi network. Heat mapping software is used in conjunction with your scaled floor plans to take Wi-Fi measurements using a laptop at regular intervals throughout your site.  This survey differs from our Wi-Fi site survey in that it is a survey of an existing Wi-Fi network. It is important that all Wi-Fi access points are hence operational prior to commencing the survey.

In addition, spectrum analysis of the Wi-Fi bands is completed during the visit to monitor for any sources of interference.

Comprehensive documentation is provided detailing the proposed solution including photographs of the proposed access point locations in a bespoke report. Also provided is a separate survey report containing a selection of visualisations depicting Wi-Fi signal levels, Wi-Fi coverage etc commonly known as ‘heat maps’.

Wi-Fi Health Check

This service includes the steps of a Wi-Fi Verification survey but also includes a full assessment of the configuration of the Wi-Fi access points.

If applicable, the configuration of the Wi-Fi client devices can also be assessed with a view to optimising the configuration on both the Wi-Fi access points and end devices. This is a very popular service as it is tailored to trouble-shoot the common issues when Wi-Fi is deployed including co-channel and adjacent channel interference. Spectrum Analysis of the Wi-Fi bands is also conducted to assess the site for any sources of interference that may be contributing to poor performance of the Wi-Fi network.

A comprehensive Wi-Fi Health Check report is provided along with the Wi-Fi Verification Survey report containing the visualisations and the results of the Spectrum Analysis.

This report provides a summary the various tests carried out and highlights any issues that have been identified. Any recommendations are also included in this report.
