Optimal line-of-sight data transfer spanning up to 1 meter (approx. 3 feet) within a 30-degree receiving cone .
Typically feature native plug-and-play support, automatically recognizing the USB-to-IrDA bridge chip (frequently utilizing MosChip, SigmaTel, or ASIX controller architectures).
Because infrared data transfers depend entirely on light particles (photons), maintaining proper physical alignment is key to achieving the maximum .
