Learning Daily | #1 | 802.11ad

Humans are creatures of learning. It is what we do, and what consumes much of our lives. The brain is a sponge, and we never stop soaking-up knowledge. We learn daily, so hopefully my sharing of what I learn will possibly introduce you to things of which you have not-yet-heard or learned.

So… 802.11ad is the relatively new, totally-redesigned wireless standard. I learned of it recently and better-rounded my knowledge of its specifications and quirks today:

802.11ad introduces a new band of frequencies for transmission: 60GHz. This new band has a throughput of about 5Gb/s. You will read that the ad standard has a throughput of about 7Gb/s, but I assume that to be the combination of throughputs of the 2.4GHz, 5GHz, and 60GHz bands combined. 

The downfall: Shorter wavelengths do not pass through obstacles as well as longer wavelengths. So substantially increasing the wavelength of the new frequency band to 60GHz should make it not as able pass through objects as easily as the bands in the previous standards? …that is correct! So why, then? Line-of-sight seems to be a must for the new standard. –I don’t know whether this is an attribute of TP-Link’s router design or not, but indoors, the 60GHz frequency band seems to bounce around objects in a room (a great connection without line-of-sight).  Along with that, ad doesn’t stand a chance outdoors. Just a human body between connection points can cause the connection to drop completely, and there is nothing for the signal to bounce-on to make it around obstructions.

Does it suck? Well, kind-of, but not really. The speed is fantastic compared to the previous 1Gb/s-throughout wireless standard (ac). If your router provides you with a solid connection as you move about your workspace (so if the signal bouncing around objects is really real), then no, it absolutely does not suck
