ARdio

Immersive tech enabled field tools bring benefit to IBC Design

In-Building Coverage (IBC) Radio Frequency (RF) designs typically go through a multi-step process detailed in the table below. Field validation is typically involved to move a project from quote to installation. ARdio was conceived in order to optimise workflows around field validation, by allowing for RF design visualisation in AR and 3D real-time while on site.

Prior to ARdio Adoption

Despite the field validation, the actual performance levels after project completion often fall short behind the design, making costly re-works necessary and prolonging project duration.

Business Challenges AR Introduction Addresses

Through the RF design visualisation in AR, that the ARdio toolset is able to implement together with efficient workflow processes, an accurate RF design can be achieved with one single site visit – avoiding costly repeated site visits as well as even more costly rectifications post installation.

Use Case with AR

ARdio App is installed on a handheld device to be used by a field technician, feeding into the designated backend enabling the connected workforce and workflow management.

Part 1: Using smart visualisation (2D and immersive as required), the on-site field technician validates and, if needed, rectifies the most common and detrimental RF-design pitfalls:

  • walls and other obstructions inaccurately represented in as-built-drawings and floorplans, and
  • planned equipment installation locations including cabling not feasible.

Part 2: The corrected and marked-up floorplan gets pushed via API to the RF design tool Twinkler, returning immediately the resulting RF propagation. Using ARdio App, the field technician is able to visualise this predicted coverage in 3D in AR as well as via 2D heatmaps as required.

Part 3: Based on this, equipment choices, locations and settings are approved or amended by the field technician, supported by back-office where required. Design gets finalised while field technician is still on site.

Part 4: Finalised design and resulting RF propagation are visualised on site for final checks and customer approval.

Above parts are all elements of the field design validation. In-Building Coverage Radio Frequency designs generally go through the following process steps:

Outcome with ARdio

 

Presales

based on floor plans and customer requirements, prepare preliminary RF design in back-office, including passive DAS design and power budget

  • preliminary BOM

  • high level quote

(same as without ARdio)

Field Design Validation

site survey to validate, edit & update:

  • floorplans,

  • RF design,

  • equipment locations & cabling

  • marked-up plans including all information necessary to prepare detailed design

  • final BOM

  • final floorplans

  • final heatmaps

  • cabling design

  • link budget

Detailed Design

in back-office, prepare:

  • final designs: floorplans, DAS, heatmaps, equipment room, cabling

  • approvals: internal, client, builder, architect, MCF

  • final BOM

  • final floorplans

  • final heatmaps

  • cabling design

  • link budget

  • approval reports

  • for-construction documentation
