Intel’s Launches WiDi 3.5: Faster, Lower Latency, Miracast Certified, USB Support
Before we dive into the new features, let's backtrack a quick moment. Intel's WiDi technology, if you're not familiar, cuts the cord and allows supported laptops and Ultrabooks to connect to a TV wirelessly. All that's required is a supported platform (Arrandale, Clarkdale, Sandy Bridge, and Ivy Bridge systems), an Intel wireless adapter, and a WiDi receiver, which you plug into your HDTV.
Version 3.5 of Intel's WiDi technology ups the ante with a 10x reduction in latency, though you'll need an Ivy Bridge system paired with the latest adapters to see that kind of improvement. It also adds support for streaming USB devices, so if the receiver is equipped with USB ports, you'll have access to wireless USB HID devices like keyboards and mice.
"Wi-Fi users around the world want to experience multimedia on the device of their choice - no matter what brand - and Miracast is the breakthrough they have been waiting for," said Edgar Figueroa, CEO of Wi-Fi Alliance. "We have been delighted with the level of enthusiasm and support among our member companies for this new offering."
In short, the new WiDi spec is faster than before (Intel claims 60ms latency on Ivy Bridge systems and 250ms on Sandy Bridge, using one of the new adapters), better supported, and has the ability to stream Full HD and 3D content.
