    WiGiG confirmed working on Haswell and newer. In order to upgrade system with WiGiG, one needs either:

    * A device with fully-wired A-key m.2 2230 WLAN card (recommended for best functionality);
    * A device with E-key m.2 2230 WLAN slot with both pcie lanes wired to the slot will require a cutout in Intel WiGiG card. Device with m.2 WLAN slot with single pcie lane wired to it WILL require exotic adapters *
    * A device with minipcie slot will require an m.2 adapter to second pcie lane, example - notice the jumper. *

    * - if Intel WiGiG implementation is used, these options WILL require a USB to DP (or HDMI) dongle for wireless display functionality - native video ports on the dock WON'T work.


    * Parts (Intel)
    1. Intel 17265 / 18260 / 18265 WLAN card; 18260 recommended because 18265 might come with wrong firmware (for WirelessVR) and won't work for Wireless docking, while 17265 is too wide to physically fit in many systems
    2. Intel 10041R WiGiG Antenna-M,
    3. MHF5-MHF5 cable of suitable length,
    4. Heat shield for WiGiG antenna,
    5. Some WiGiG docking station (Dell WLD15 recommended).

    * Parts (QCA)

    1. QCA9008-TBD1 WLAN card,
    2. Antenna,
    3. Weird proprietary cable of suitable length,
    4. Heat shield for WiGiG antenna,
    5. Acer Prodock Wireless docking station
    Some QCA WiGiG datasheets and drivers can be found here.

    * Installing WiGiG antenna:
    With a traditional laptop or tablet, antenna positioning on the display lid is pretty straightforward - just put it on upper part of the display lid wherever you want, on the side where cabling would be easier - or even inside the lower case if you have enough space.

    With a convertible or tablet, antenna positioning requires careful planning. Generally, you want it where you don't grab the tablet (obviously) and don't usually rest your hands. If you favor single portrait orientation, WiGiG antenna should be on the upper side in this orientation so that you don't disconnect when laying the device on your legs - otherwise you might want to position it closer to tablet center. Having enough space to route the cables is very important.

    * WWAN:
    For WWAN, I used WLAN antennas - because they occupy less space. My current LTE frequency is 1800MHz (Band 3), so coupled with EM7455 this setup works just fine; fallback to UMTS occurs earlier than smartphone when entering an area with poor LTE signal, but in areas with good LTE signal all is fine and dandy.

    Using WLAN antennas with thin cables was also of importance, since my system has cable guides for only 4 antennas, while I routed 5. You can see how I improvised on pictures below.

    * Additional:

    My research showed that all laptops with factory-installed WiGiG have the same WiGiG antenna orientation, even when it makes cabling harder - so I ended up rotating mine accordingly, there might be some reason for that after all. After rotating, I suffered problems with WiGiG & LTE coexistance - as soon as I used LTE (LTE particularly, HSPA was OK), WiGiG started disconnecting and reconnecting intermittently (producing error 0x1014 in Intel Wireless Dock Manager) to a point of being unusable. After long fruitless troubleshooting, I switched WWAN main and aux cables on the WWAN modem, and voila, works just fine. Some piece of plastic is required beneath WiGiG cable near the antenna connector, otherwise it may get loose and you'll have to reattach it; error code 0x1020 in Intel Wireless Dock Manager is pointing exactly at that.

    Thanks for the detailed post & pics Starlight5. Internals look identical to a Thinkpad Yoga 260.

    I must have opened up my TPY260 about 20 times by now to fix reception / antenna issues, and finally broke the LCD ! (Have replaced that now)

    So I got an EM7455 from aliexpress and installed it. The included antennas are only around 20 cm so they don't reach the top and if I try to put them near the edges then only 2 of them can go there so I put the GPS antenna near the bottom edge. See Image 1 below.
    Now, I get pretty ****ty reception compared to using the same SIM in any phone or dongle. Tried all permutations / combinations of the 3 antennas.

    My queries are:
    1. Can I extend the antenna cables by soldering a 20-30 cm section of wire ? so that I can try and put them in the positions indicated in your pics.
    2. The antennas are different shape than yours in the pic above (or my built-in wlan antennas in the TPY260) (see image 2 below), so should I get ones which look like the original built-in ones and with longer cables ? If yes, then will this one work ? or this one ?

    Thanks.

    @amitabhr my system is indeed TPY 260.

    First of all, you don't need a dedicated GPS antenna - it does not provide substantial benefit, yet makes things noticeably harder to fit. Your AUX antenna will serve as GPS antenna as well, if you disconnect the GPS antenna.

    To determine if antennas you bought are any good for your LTE frequency, try them outside the laptop at some distance, e.g. putting on a table in position you're going to use them inside your laptop. I recommend speedtest.net. Not sure how soldering cable (or using extension cable) would affect antenna performance, it's definitely easier to buy a set with longer cables.

    Try the built-in WLAN antennas for LTE as well, and compare their performance with the antennas you bought. Remove your WLAN card while doing so, or connect other antennas to it. This will provide a definitive answer on whether you should get similar WLAN antennas for LTE, or not. I personally used t460s WLAN antennas for LTE, but they are somewhat expensive.

    If you decide to buy a new set of antennas, measure the length of both factory-installed antenna cables, add a couple cm to the left and subtract about 10 cm from the right; also, add 3-4 cm if antenna sold has the wrong cable orientation - and that's the minimum cable length for each antenna you need. I'm not good with physics, so no idea whether buying a matching main+aux set of antennas makes any benefit or not.

    Good luck!

    p.s. Regarding the display replacement you bought - is it anti-glare like the factory one, or glossy? Does backlight control work fine? How much did it cost you?

    Apparently the 60ghz band is wanted for wireless VR...

    Intel Discontinues WiGig Cards to Focus on VR
    http://www.anandtech.com/show/11829/intel-discontinues-wigig-cards-to-focus-on-vr

    "In a surprising move, Intel has announced plans to altogether discontinue their 802.11ad products. The company intends to cease shipments of all of its current-generation WiGig devices by late 2017. Intel has not announced any replacements for the 802.11ad parts and says that it would focus on WiGig solutions designed for VR applications.

    Intel is formally initiating the EOL program for the Wireless Gigabit 11000 and Tri Band Wireless-AC 18260controllers, the Wireless Gigabit Antenna-M M100041 antenna and the Wireless Gigabit Sink W13100 sink today (September 8). Intel is asking its partners to place their final orders on its WiGig-supporting network cards, antenna and sink by September 29, 2017. The final shipments will be made by December 29, 2017.

    Typically, Intel continues to sell its products for at least several quarters after it initiates its product discontinuance plan.

    Four months is a relatively short period between the start of the EOL program and its finish, which may indicate that the company has a relatively limited amount of customers using the WiGig products and it does not expect them to be interested in the devices in 2018 and onwards.

    Last year Intel already announced EOL plan for its Tri Band Wireless-AC 17265 controllers and select W13100 dock SKUs. Coincidentally, the company stops their shipments on December 29, 2017, as well."

    What a shame. Hope driver support won't be depreciated until some replacement is introduced - wired docks just suck for my usage.

    Really nice info.
    So does Intel close their upgrades for Docking WiGig?

    @boombyte they closed the topic until 802.11ay, it seems. Hopefully that would be backwards compatible.

    Never heard about ay. Will wait for updates. Really want a wifi dock. It'll be wonderful.
