However, unlike an Express configured as a remote or relay base station in a Wireless Distribution System (WDS), which shares or extends your wireless network to both wired and wireless clients, an Express set to ProxySTA does not extend or relay the network wirelessly it acts only as a bridge. In this mode, the Express acts as a wireless-to-Ethernet bridge, extending your wireless network to wired clients such as a TiVo, a game console, or a room of Ethernet-networked computers. The Express is also the first AirPort Base Station to provide a new feature called ProxySTA. (However, since the Express has no controls, you’ll still need to control playback from your computer.) Using multiple AirPort Express units, you can even stream audio, in sync, to multiple locations around your house. The Express’s AirTunes feature lets you stream iTunes audio-or, with help from the third-partyĪirFoil 3 ( $25), any other audio on your Mac-to a stereo or speakers connected to the Express’s analog/digital audio-out jack. The Express also continues to one-up the Extreme in a few areas. In addition to 802.11n support-which gives you better performance and range-the new Express inherits support for 802.11a networks, as well as PIN-based guest access, which allows you to keep your network password private, and time-based network access, which lets you limit the days and times at which particular computers can access your network. On the other hand, a number of features previously found only in the 802.11n Extreme Base Station have found their way into the latest Express model. (Although the latest documentation for the AirPort Express explicitly states that you can’t connect multiple USB printers using a hub, Apple told us that you can indeed do this with the latest Express however, the hub must be powered.) Finally, the Express supports only 10 clients the Extreme handles up to 50. (Given the Express’s single port, the benefits of faster Ethernet would likely be realized only if several wired clients were connected, via a switch, to an Express extending an 802.11n-only wireless network.) The Express’s USB port is also less functional than its larger sibling’s: although it lets you share a USB printer across your network, it doesn’t support sharing a hard drive, as you can with the Extreme’s AirDisk feature. On June 11 at the 2012 Worldwide Developers Conference, the 2nd generation AirPort Express was introduced with a new design and dual-band support of 802.11n over 2.4 and 5 GHz networks.Unlike the larger-and more expensive-AirPort Extreme Base Station, the Express doesn’t include a multi-port Ethernet switch, and its single Ethernet port is 100base-T rather than the Extreme’s faster 1000base-T (Gigabit) Ethernet. Support was later added for the draft specification of the 802.11n protocol.Ģnd-generation Airport Express 2nd generation Airport Express can also be used to easily expand wireless coverage via WDS-bridging. Audio-out supports digital optical and analog output. Now called AirPlay, the functionality requires iTunes 4.6, or newer. Airport Express supports AirTunes, which allows audio to be streamed over wireless network to the Airport Express, which then outputs the audio through its audio-out to stereos, for example. Much smaller than the full-sized AirPort Base Station, it held the title for the smallest AirPort router in existence, and included audio-out, USB for wireless printing, and an ethernet port. The original Airport Express used the 802.11g specification.
