3 wifi fun facts illustrated: A calendar with the number 20 on a wifi symbol, a doughnut with a no wifi symbol in the hole in the middle, and a portrait of Nikola Tesla

Did you know this about wireless internet access?

“Wi-Fi” Does Not Really Mean Anything

Sure, “wi” stands for wireless, of course, but that last part? It stands for nothing except “the naming consultants liked the pun on hi-fi”. The most important thing was to come up with a name that was more accessible than the name of the wireless standards (802.11x), and admittedly that seems to have worked!

The World’s Longest Wifi Signal

The longest wifi signal recorded in the Guinness Book of Records is from 2007. That was when Ermanno Pietrosemoli sent a wireless signal 382 km (237 miles) between two mountain peaks in the Venezuelan Andes. The throughput was a whopping 3 Mbps! Source: Guinness World Records

Here it may be appropriate to remind that it is neither wise nor, in many cases, legal to fiddle with the antennas of your router to extend the signals?
Don’t. Boost. Your Wi-Fi Signal.

A Wireless Doughnut

A classic router or repeater with visible antennas creates a doughnut-shaped wireless coverage field around it. In the middle there is a “hole”, that is, a zone straight up and straight down between the antennae where there is no Wi-Fi coverage.

In Wi-Fi the Weakest Link Wins Every Time

The weakest party pretty much calls all the shots in Wi-Fi. New smartphone and old router? The router drags the phone down to its level. Shiny new router and old PC? Your PC is going to be just as slow online as it used to be.

World Wi-Fi Day

… is not one of the UN’s international commemorations, but an initiative of the Wireless Broadband Alliance, which is a collaboration between several major industry players. The day is June 20, and the goal, according to the alliance, is to help bridge the digital gap. Source: World Wi-Fi Day

American Wi-Fi is Different

Local and regional laws and guidelines place restrictions on what you can do with wireless signals, and thus what wifi equipment will support.

This means that if you take equipment from one geographical area to another, or buy electronics designed for a different market, it is not certain that this will work as expected.

The best-known example of this is the use of frequency channels 12 and 13 on the 2.4 GHz band. These channels are available in most of the world, Norway included, but not in the United States. Equipment intended for the US market will therefore not support these channels.

Nikola Tesla Predicted the Internet and Wifi

The Croatian-American inventor and scientist Nikola Tesla (1856-1943) predicted a lot of technology that was to come – or become applicable – only after his time. “When wireless is perfectly applied the whole earth will be converted into a huge brain,” Tesla said in a 1926 interview. He also said “Present wireless receiving apparatus will be scrapped for much simpler machines; static and all forms of interference will be eliminated, so that innumerable transmitters and receivers may be operated without interference.”

While we wait for the last bit of that all forms of interference to be eliminated, here’s a reminder of what’s interfering with and blocking wifi signals in a typical home today.
