DWG to iBwave: a handoff checklist for wireless design teams

A wireless design can look right on screen and still create work for the next engineer. If your customer requires an iBwave project, agree on the required deliverable before choosing how to model the site. A CAD drawing, an editable RF design and an accepted customer package are different deliverables.

The useful question is specific: which parts of this project must transfer, which can be rebuilt, and how much work will that leave? Use the checklist below to test the handoff on one representative floor before committing the entire project.

Start with the receiving team's requirement

Ask the engineer who will receive the project to identify the target application and version, the required file format, and the tasks they must perform after import. Viewing a floor plan is a different requirement from editing antenna properties, recalculating a link budget or running a new propagation study.

iBwave's Design product page describes CAD floor-plan import. That capability alone does not establish which objects or RF settings will transfer from a particular export. Test the actual source file and receiving workflow.

  • Does the customer need a drawing, an editable project, a report, or all three?
  • Which application version and component libraries will the recipient use?
  • Who accepts the deliverable, and what checks will they perform?
  • Which revisions must remain possible after handoff?

Check geometry before checking the network

Begin with a permitted sample containing a known dimension, two material types, a floor transition and a small equipment set. Avoid using a visually simple floor that cannot reveal the problems your production project is likely to encounter.

After import, compare the known dimension, drawing units, orientation, floor elevation and alignment. Check that the relevant layers are visible and that duplicate or missing geometry has not changed the model. Then review the building features that matter to the RF calculation: wall materials, thicknesses, openings and height assumptions.

Record the result separately for every item. A successful file import is the beginning of the test.

Separate drawing objects from RF objects

An antenna symbol may show the intended location without carrying the antenna model, pattern, mounting configuration or transmit settings needed for simulation. Apply the same distinction to cables, splitters, headend equipment and other network elements.

For each required object, inspect what the receiving engineer can edit and calculate. Document whether it transferred as usable geometry, retained the needed properties, requires reconstruction, or is outside the tested workflow. Do not label the whole project compatible because one layer looks correct.

A copyable handoff acceptance worksheet

For each line below, record: required output; test result; remaining work; responsible person; and acceptance date. Use the statuses Passed, Rebuild required, Not tested and Not required.

  1. Coordinates and dimensions: units, scale, orientation and a known reference measurement.
  2. Building model: floor alignment, elevations, wall geometry, materials and openings.
  3. Network geometry: equipment positions, labels, cable routes and floor transitions.
  4. RF properties: supported equipment models, antenna patterns, bands, power and relevant losses.
  5. Calculations: the inputs and outputs the receiving engineer must reproduce or rerun.
  6. Commercial package: bill of materials, report sections, revision identifier and open assumptions.
  7. Customer acceptance: reviewer, required format and explicit sign-off conditions.

Measure the complete workflow

Time the original modeling, export preparation, import checks, reconstruction and final review separately. Compare that total with the team's current process on the same project scope. Include a revision: a handoff that works once may become expensive when a customer changes the layout or equipment.

For example, a fictional pilot might save three hours in modeling but add one hour of export preparation and two hours of reconstruction. Its net time saving would be zero. This is an illustrative calculation, not an eino benchmark. It explains why the final accepted package is the right finish line.

Evaluate the eino handoff on your required output

eino's documentation includes a DWG export guide for iBwave handoffs and a file export reference. Detailed guides may require sign-in. Use the current supported workflow and a representative file to establish the result for your environment.

A DWG handoff should not be assumed to produce a native iBwave project, preserve every RF object, or satisfy a customer's acceptance criteria automatically. Define the requirement and test it with the receiving engineer.

Bring your required handoff to an eino demo. Start with the target format, a permitted sample and the worksheet above, so the evaluation answers a real delivery question.
