Test results

Below you can see all test results in two tables - one for 5 GHz and one for 2.4 GHz.

Results 5 GHz 

If we look at the results, a number of things stand out. First of all, we see that in a real world environment 160 MHz produces little more than 80 MHz wide channels. In the Faraday Cage, we do see the potential advantage, with speeds averaging between 100 Mbit/s (LAN-WLAN) and 200 Mbit/s (Wlan-LAN), higher than in the big bad outside world.

It is also striking that the PC Specialist laptop with the Killer WIreless-AC 1550 on board with 80 MHz wide channels knows how to get the most out of the chip: the results in the cage are almost the same in both directions. The same can certainly not be said of the laptop with the Intel 7260 adapter. The results obtained by these 80 MHz wide channels in the Faraday cage are about twice as high under the line as in the real world. In terms of performance, the added value of the Killer Wireless-AC 1550 is already clearly visible when using 80 MHz wide channels.

Results 2.4 GHz

At 2.4 GHz, we can safely conclude that we see strikingly consistent results across the board. It is also interesting to see that the throughput speed in the office environment is not much lower than in the Faraday cage.
