IrDA. Ma’lumotlarni uzatishning infraqizil assotsiatsiyasi 1993 yildan boshlab qisqa masofada ma’lumotlarni uzatishning infraqizil uchun ochiq standart asosida ishlaydi.

IrDA spetsifikatsiyasi ikkita standartga asoslangan – Hewlett Packard tomonidan ishlab chiqilgan 115 Kbit/s fizik daraja protokoli.

Hozirgi vaqtda IrDA – ochiq infraqizil kanali bo’yicha ma’lumotlarni uzatishni tashkil qilish uchun eng keng tarqalgan standartlardan biridir. Bu 9,6 Kbit/s va 16 Mbit/s gacha bo’lgan tezlikda 1 metrgacha bo’lgan masofada ishlashga mo’ljallangan «nuqta-nuqta» aloqa protokolidir.
