Inkjet coders (connected production lines)
Fixed installation, little data, steady reporting of status and consumables: a 4G Cat 1 or Cat 1 bis DTU is the most economical.
222G/3G switch-offs planned in the next 36 months
What matters
- For fixed equipment, indoor coverage at the site matters; add an external antenna if needed
- When exporting to several countries, pick models that cover every 4G band there
- Remote maintenance should weigh data costs against long-term connection stability
