60 GHz Wi-Fi: A 2026 Reference to WiGig and Samsung's 2014 Claim
The short answer
60 GHz Wi-Fi, often called WiGig, is for fast local links with suitable hardware and a clear signal path. Samsung's 4.6 Gbps figure came from a 2014 announcement. It is not a promise of faster broadband or better coverage through walls.

What's covered6
60 GHz Wi-Fi uses a much higher radio band than the familiar 2.4 GHz and 5 GHz home network. It can carry lots of data over a local link. The catch is the path: a wall or an object in the way can matter more than the headline speed.
This reference starts with the Samsung news that drew attention to the band in 2014. It then separates that announcement from the standards and from what a PC owner can use. For a whole-home connection, start with our router and Wi-Fi setup guide.
60 GHz Wi-Fi suits a fast local link when both devices support it and the signal path is clear. Samsung's 4.6 Gbps claim dates to 2014. Check the exact hardware pair and its placement rules before buying. A faster local radio link does not raise your broadband service speed.
Samsung's 60 GHz Wi-Fi announcement in October 2014
On 12 October 2014, Samsung announced its 802.11ad-based 60 GHz Wi-Fi technology. The company stated a rate of up to 4.6 Gbps, or 575 MB per second. Its fivefold comparison used 866 Mbps as the earlier consumer-device rate.
Those numbers describe Samsung's announcement at that time. They are not results from PC4U tests, a speed promised by every WiGig device, or a comparison with every router sold today. Gbps measures gigabits per second; MB/s measures megabytes per second. Keep the units when comparing the two.
Samsung described beam-forming antennas, which aim the radio signal toward the other device, and fast changes to that aim as conditions shift. It also acknowledged weak signal penetration and loss along the path as barriers to using the band. Its planned uses ranged from audiovisual to medical equipment. These were plans in the 2014 release, not proof that a particular product later shipped.
What 802.11ad and WiGig mean
802.11ad is part of the IEEE 802.11 family of wireless networking standards. IEEE's working-group overview describes the amendment as enabling very high throughput in the 60 GHz band, typically 57 to 66 GHz. WiGig is the name used for this kind of multi-gigabit wireless link.
Think of three separate questions. The standard sets out how a radio link can work. A chip or device implements some of those capabilities. An application, such as copying a file or driving a dock, gets the result of the complete system. The name of the standard alone does not answer all three.
For example, Lenovo's ThinkPad WiGig FAQ covers a specific set of ThinkPads and a specific WiGig dock. It says the wireless module and antenna were fitted at manufacture and could not be added later to those systems. That is a useful warning against buying an old dock on the strength of a laptop's ordinary Wi-Fi label.
Why 60 GHz range needs a model-specific answer
There is no single useful distance to promise for every 60 GHz product. Read the instructions for the pair of devices you plan to use. A desk dock and an outdoor radio link are different systems, even if both use the same broad band.
Lenovo's dock FAQ requires a clear line of sight between the dock and ThinkPad. It says objects can block the signal and that it cannot pass through walls. For that dock, Lenovo lists 3 feet with a tablet or closed lid and 6 feet in notebook, stand or tent modes. These are limits for the named equipment, not a range rating for all WiGig.
The same FAQ reports USB reads up to 80 MB/s and writes up to 60 MB/s. Those application figures show why a large radio rate should not be treated as the speed of every task. Check the peripheral and its port as well. Do not use a 4.6 Gbps headline to estimate the time to copy a folder through an unrelated dock.
802.11ad versus 802.11ay
802.11ay builds on the earlier work in the 60 GHz band. IEEE lists its publication date as 28 July 2021. The IEEE 802.11ay-2021 summary describes at least one mode designed to support a maximum throughput of at least 20 Gbps, measured at the MAC data service access point. That is a defined place in the network stack, not a measured home file-copy result.
NIST's research on 802.11ay explains several changes: channel bonding and aggregation, plus multiple-input and multiple-output radio links, or MIMO. Bonding joins channels to provide more room for data. MIMO uses multiple radio paths. NIST discusses these as ways to extend 802.11ad; it does not establish the speed of a product you might buy.
The practical distinction is hardware support. Read the full model specifications and the maker's compatibility list. Do not infer support for a newer mode, a particular dock or a headset from the phrase “60 GHz” alone.
Does WiGig matter for a home PC?
It can matter when you have a specific local job and a compatible pair of devices. Before spending money, work through these checks:
- Name the job. Is it a supported wireless dock, a headset link or a transfer between local devices? Write down the exact models at both ends.
- Check the PC hardware. Look for explicit WiGig or 802.11ad/ay support in the manufacturer's documentation, plus any required antenna, card, driver and operating system.
- Check the partner device. A suitable radio in the PC does not establish that a particular dock or accessory works with it.
- Check the path. Use the maker's range and placement rules. Test the desk position with the screen and other large objects where they will normally sit.
- Check the task rate. Use figures for the actual port or workload where available. A wireless link rate is only one part of the route.
- Keep broadband separate. Faster transfer between two local devices does not raise the rate supplied by your internet service.
These are buying and setup checks, not a claim that every PC needs WiGig. If the problem is weak reception in another room, inspect the home network first. If you are planning a machine, include the required connectivity in the PC build and budget plan.
Verdict: choose 60 GHz Wi-Fi for a defined local link
Samsung's 2014 story is a useful starting point for understanding the appeal of 60 GHz Wi-Fi. Keep the dated claim attached to its date and source. For a purchase now, check the exact device pair and its placement limits. Choose for that job rather than treating WiGig as a general fix for home Wi-Fi.
