`

`1 WHAT IS AUTOTUNE?
`
`AutoTune is a new feature in Impinj’s Monza 6 family tag chips that tunes the chip’s radio on
`every power-up to maximize tag sensitivity for the current environment.
`
`All tags experience varying performance from application to application due, for example, to
`the differences in materials of the tagged items such as shirts, jeans and polybags; or due to
`different operating frequencies in US and Europe. Currently, tag manufacturers take these
`factors into account either by increasing tag size or by carrying multiple application-specific
`tag designs. AutoTune compensates for these factors, allowing smaller tags or tags that can
`be used in more applications. Best of all, AutoTune does not require any user intervention or
`custom commands. AutoTune is fully automatic and works all the time.
`
`Every tag has a range of frequencies over which it offers the best readability. A tag’s
`bandwidth is the width of this frequency range. AutoTune increases a tag’s bandwidth.
`Wideband tags are more tolerant of tag-manufacturing variations, differences in materials of
`the tagged items and environmental variations (such as from store fixtures) than narrowband
`tags. AutoTune reduces tag SKU count throughout the supply chain, reducing complexity
`and cost. AutoTune also improves tag readability in retails stores and opens new item
`categories for retail tagging that require small tags.
`
`AutoTune is Impinj’s patented technology and available only in Monza tag chips.

`
` FREQUENTLY ASKED QUESTIONS
`
`Will AutoTune slow down my read/write process?
`
`No. AutoTune does its tuning during tag power-up.
`
`How does AutoTune affect my tag antenna design?
`
`AutoTune enables you to design smaller tags with improved sensitivity and/or wider
`bandwidth. It can reduce off-tuning from dielectric loading.
`
`Can I disable AutoTune?
`
`Yes. You may disable AutoTune using a Gen2-compliant write to a memory location outlined
`in the Monza 6 datasheet.
`
`How do I know what tuning value AutoTune chose?
`
`If you are an antenna designer and want to check the tuning value, you can do so using a
`Gen2-compliant read of a memory location outlined in the Monza 6 datasheet.
`
`Do I need to buy new readers to use AutoTune?

`

`No. AutoTune does not require new equipment or any changes to existing reader
`infrastructures. AutoTune just works, invisibly and automatically.
