Apple has made yet more improvements to AirPlay in iOS 8 by enabling compatible devices to make direct connections with each other for content streaming. This eliminates AirPlay’s reliance on a Wi-Fi network and fixes one of its biggest limitations. In previous versions of iOS — including the latest iOS 7.1.1 release — all of your devices must be connected to the same Wi-Fi network to partake in AirPlay streaming. You couldn’t stream music from your iPad to your iPhone while on the train, then, and you couldn’t stream video from an iPhone to an Apple TV in a hotel that doesn’t offer Wi-Fi.
