I have a Intel WiGig laptop + dock that uses wireless ad under the hood.

The bandwidth can be used for much more than just network transfers. I've personally had 2 1080P displays playing video + USB3 external hard drive transferring at max speed + Gigabit Ethernet transfers using the dock without anything skipping a beat.

Wireless ad docking + wireless charging on a laptop will be absolutely amazing.

That's 7Gbps shared between all connected wireless devices connected to 8-24 1Gbps switched wired ports.

Thats actually OK. Advertised wifi speeds usually manage 20% of that in real life so sounds about right.

Bullshit, your device is at fault and not the protocol. I bought a 802.11ac dongle with external 10dbi gain antennas and have been enjoying extreme speeds and connection strenght throughout the house, not to mention to the routers of 30 of my neighbours.. And that's only 5GHz. For comparison, at my desk three walls away I used to get about 40-50nW signal level off my built-in adapter and antenna in my Lenovo laptop. With the new setup - 60mW... The router sends at 100mW. We're talking pushing 90MB/s+ constantly no matter where in the house with absolutely no connection drops.

Why are people down voting this?

If you buy a cheap AC router and expect a tiny built antenna to max out the bandwidth you will be disappointed.

I get over 1Gbit real tested bandwidth between my main desktop using a decent dongle with external antennas and a high end router.

Even iscsi works well with this setup the NAS is connected on 10gig Ethernet to my router. With MU/MIMO you can also get full duplex if you set it up. The dongle is built into the motherboard and it's connected via pcie. Before that I had an asus pcie x4 wireless card which worked just as well(maybe even better).

Probably because his comment was rude while also not being particularly constructive. If he'd said it more nicely, it might have been better received.

> ... while also not being particularly constructive.

Eh?

The guy mentioned that he switched from using the built-in antenna on his laptop to a honking external antenna and now gets 720mbit/s performance anywhere in his house. That's quite constructive. I guess the only way it could get more constructive is if he mentioned the model of hardware involved... but I expect that you'd get similar results with any AP capable of 720mbit/s transfer to a single client. If your AP is fast enough, then it's all about SNR.

>but I expect that you'd get similar results with any AP capable of 720mbit/s transfer to a single client.

One should expect that, but almost no one uses wireless that way. If you have just a single client the most efficient method is to run a cat5 cable and get 1000mbit/s at a much lower cost than putting in expensive AC equipment, barring an expensive engineering issue of making a cable reach that place. The problem with wireless is everybody has to play nice and be able to see each other or it quickly falls to the 20% actual usable bandwidth rather quickly. Do you have neighbors with a wide bandwidth AC router and healthy streaming video habit? Don't expect to get max data transfer rates. Do you have lots of portable devices, especially cell phones that like to go into low power mode, or get set in places where they can reach the router but become hidden nodes to other clients in the network?

Can you tell us what model router and dongles you are using?

RSSI -- Receive Signal Strength Indicator -- is reported in dBm, which is a log-scale unit of watts. +20dBm is approx. the max transmit power for WiFi, and equates to 100mW. 1nw is eqivalent to -60dBm which is a pretty decent signal strength for WiFi, but won't provide max data rate. By comparison, the minimum power to operate at 1Mbps is about -98dBm.

Then again, receiving at 60mw (+17dBm) would overdrive any of the WiFi devices I ever tested and path loss of just 3dB (assuming +20dBm transmit power) is not achievable over the air, even with a near-field antenna. Keep in mind many devices actively tamper with the RSSI value reported up through NDIS, so while it's possible for a card to report it is receiving at +17dBm, unless you have hard-wired the hirose connectors between AP and STA it's not actually the case. Nor would a receiver work very well with so little path loss in any case, it would be completely over-driven.

Transmission power in milliwatts (mW) is directly convertible to decibel-milliwatt (dBm).

This is arguing if your car is doing 1 to 60 miles or 1 to 100km in 4.3 seconds.

For the most part you measure transmition power in mW and received signal strength in dBm.

On the flipside, is it ok that we are still shipping 1gb lan ports like 20 years after they became commonplace? I'd hope that at least enthusiast class hardware would start using 10gb at some point.
