PDF and spreadsheet

Important note on accuracy
The workbook is intended as an engineering aid and documentation template. It does not replace professional judgement, manufacturer datasheets, or the latest revision of the relevant standard. For cellular band and channel data, always verify against the current 3GPP specification and your operator or regulator requirements.

FAQ
Is this the same as the free online calculator?
The free online calculators remain available. This bundle adds a printable planning workbook and an editable spreadsheet for offline use.
Does the spreadsheet calculate my own link?
Yes. Change the highlighted inputs to recalculate path loss and link-budget results. The PDF is a printable reference and worksheet, and the purchase does not include bespoke engineering advice.
Can I use it at work?
Yes, for the purchaser’s personal and internal professional use. You may not redistribute, resell or publicly share the files.
How do I receive the files?
We verify the completed payment in PayPal and email both files within 24 hours to the address on that payment. Returning to our website does not itself confirm payment.
