Samsung Electronics, a member of the WiGig Alliance, has just announced an implementation that is capable of achieving 4.6 gigabit (575MB/s) speeds under the 802.11ad standard. Samsung claims that they have overcome "the barriers to commercialization" of wireless over 60GHz. This band has several disadvantages, including resonance with oxygen molecules (included under the blanket of "path loss" in the press release) and its opacity to many solid objects (referred to as "weak penetration properties" in the release).

Some features that Samsung credits themselves with are beam-forming with less than four-tenths of a millisecond latency and the ability to track multiple devices simultaneously. Beam-forming in particular is said to help offset the mostly line-of-sight properties of earlier 60GHz prototypes. This allows the signal to be directed toward devices, typically by manipulating interference patterns to reduce the energy lost by transmitting to locations without a receiver and thus giving more energy to the locations that do.
Its usage as a product will mostly depend on how tolerant they are to non line-of-sight situations. This rate is comparable to a high-end SATA SSD. Samsung claims that it will be useful for their Smart Home and Internet of Things initiatives, similar to the Stanford and Berkeley announcement last month, but also mention it in terms of medical devices.

Dell has launched a new docking station for its laptops. In an interesting twist, the dock connects to the computer over an 802.11ad “WiGig” link to provide up to 7Gbps bandwidth between the dock and laptop. The Dell Wireless D5000 docking station supports multi-display, USB 3.0, and audio output. According to Dell, it is the worlds first commercially available wireless dock.
The Wireless D5000 dock pairs with Dell's 1601 WiGig card, which is currently only available with Dell's Latitude 6430u laptop. Pairing is a simple matter of hitting the pairing button and hitting connect in Dell's Connection Manager software. A single USB 3.0 port and headphone jack are also available on the front of the device.
Rear IO on the Dell Wireless D5000 dock includes DC power jack, Ethernet jack, two USB 3.0 ports, a single HDMI port, and one DisplayPort output. Additionally, the D5000 uses a WiGig radio to provide the connectivitiy over a wireless link. WiGig, or 802.11ad, uses the 60GHz wireless spectrum to provide high bandwidth at short distances. The chip Dell is using in the dock is capable of falling back to 2.4GHz or 5GHz bands–you can expect significantly slower speeds in that situation though. You will be able to take your computer with you, set it on the desk and have two desktop monitors, a wired network connection, and USB 3.0 ports. Not bad, though Justin Kerr over at Maximum PC notes that wireless power for charging your laptop would have really ratcheted-up the dock's usefulness.
In terms of connectivity, there is nothing especially new here that Thunderbolt docks are not already providing (aside from the wireless nature, of course). I say this because the Dell D5000 dock's pricing is in line with many of the Thunderbolt options. If you can stand a wired connection to the dock and your laptop/ultrabook has a Thunderbolt port, you could grab a dock with similar port options, higher theoretical bandwith, and a Thunderbolt passthrough. The Dell D5000 is available for $270 at Dell's online store, but it is reportedly cheaper if purchased with the Dell Latitude 6430U laptop. In that scenario, the wireless dock is only $190 (which is, admittedly, pretty good even against Thunderbolt docks).
