The “Internet Of Things”, or simply IoT, what’s it good for?

Internet of Things

Internet Of Things, the IoT

We’ve all heard the hype about the IoT, the Internet Of Things, but is it really a hype? Back in the dark ages (the 90s), a company called Novell already claimed that coffee machines and refrigerators would be equipped with a mini OS and an IP address, so automatic ordering systems could make sure you always have specific foods (or beer) in your fridge.

But at the same time the world was running low on IP addresses, so actually providing all these electronic devices with a unique address was a challenge. The solution was IPv6 which provides a few more addresses than IPv4 does.

Enhance your WiFi by using beer!

Beer can WiFi booster

Bad WiFi reception

Bad WiFi reception is one of the most common annoyances these days. Especially in residential areas where every house has at least 1 access point and each family is working hard to fill the ether with their own signals. A quick fix can solve this problem relatively easy by using an empty beer can (a soda can also works).

The aluminum of an empty beer can enhance the WiFi-signal significantly. You could buy an expensive repeater, but a beer can is immensely cheaper (and is more fun to get too). Our good friend youtube shows us this instructional video.

Step by step

  1. Go to the supermarket
  2. Buy (at least) 1 can of beer (a premium brand will do better than some random cheap brand)
  3. Empty the can (don’t throw the beer in the sink at all times! Drinking is the preferred method!)
  4. Clean the inside of the can by flushing it with some water
  5. you will need a knife or scissors to open up the can and some material to fix the empty can to your router
  6. Remove the lid, used to open the can
  7. Cut off the bottom of the can
  8. Cut off the top of the can, leaving a small piece near the old drinking opening
  9. Cut the can from top to bottom at the opposite side from the drinking opening
  10. Carefully bend the metal so it (sort of) looks like a satellite dish
  11. Place the brand new dish shaped beer can on your access point, by sticking the antenna through the old drinking opening
  12. Fix the “dish” so it doesn’t fall off

steps

This little trick should enhance the signal strength by a factor 2 or 3. This only works for access points equipped with an external antenna. For antenna-less models you could try creating a somewhat larger dish and placing the whole access point on the bigger dish, but I don’t guarantee this works. You could for example use a keg, but I doubt that you can cut it by using scissors 😉

 

EMC World 2014: short week and too much to do

EMC World 2014

It’s that time of the year again: EMC World

15 Thousand nerds gathering in Las Vegas for the yearly week of EMC propaganda. That’s what a lot of people might think it is anyway. It’s the 2014th edition… that doesn’t sound right. Ehm, oh well, you get my drift. Well, maybe it is nerd-week, but hey: every vendor who thinks they’re the best in something is doing this sort of events and besides that, it’s a great event to meet people you haven’t seen in a year or so.

Social networking in real life

Social networking, gathering knowledge of things to come, looking for solutions to challenges you already have in your normal day jobs, looking for insights in things on your wish list. Bacon, unicorns, hardware and a loooot of “software”, since that’s the trend since a few years. No matter how you explain it:

IT is in Las Vegas, baby!

WiFi – San Francisco International Airport

Free WiFi

SFO – San Francisco International Airport

Ok, Dublin was a good experience, but SFO is good and easy too! After looking for hot sport, I selected the “#SFO FREE WIFI”, opened a random website, got the following page:

WiFi

I selected “Accept the Terms” and that was pretty much it. No forms to fill out and so far I’ve seen no time limit. Good to go!

WiFi – Dublin Airport

Free WiFi

Free WiFi

DUB – Dublin Airport

Well, I wish all hot spots were like this! After I got off the airplane, I enabled WiFi again and voila, I selected the “Dublin Airport Free Wifi” hot spot. After clicking it, I got a new page:

DUB Free Internet

Click to accept and I was ready to go! This was really easy! No limits, not forms to fill out. Fantastic!

WiFi – Brussels Airport

Free WiFi

BRU – Brussel Airport

My first report in the series “WiFi all over the world” is about BRU. The airport offers free WiFi through the TELENETHOTSPOT. It’s available just about everywhere you go on the airport, but on an Apple device this can be a bit of a hassle if you try to connect for the first time.

After selecting the hot spot, you are supposed to be connected to a logon page, but I faced that this page didn’t appear until I retried 3 or 4 times. Opening a browser and surfing to a random site might help.

You are presented with a page on which a commercial is shown. Again, on an Apple device this didn’t work, but I found out that simply waiting half a minute, maybe a minute, helps.

15 seconds (a bit longer)

You now see a page on which you need to fill out a form with PIn codes, passwords and your wife’s birthday (just kidding, but that form is unnecessary long).

You will then get logon credentials and you’re good to go. Enjoy your WiFi!

(Free) WiFi all over the world

This year I’m doing my fair share of traveling again and I’ve decided to write a blog on each of my Free WiFi experiences during the year (or longer?) It could very well be an ongoing comparison of the various places, public or private and even airplanes!

Free WiFi

WiFi at work is fantastic and at home it works like a charm as well, but tomorrow I’m flying to San Jose (California) and I need my internet access! I brought a book just in case I’ll be disconnected for a long period of time.

WiFi radiating

The “WiFi all over the world” series will start tomorrow when I’ll be flying from BRU to DUB to start with and from there to SFO. I will be picked up at the airport and I’m told the ride has on-board WiFi as well. I’ve never tried using WiFi in a car so far, but hey! I’m not driving myself this time, so I should be able to get some airtime when driving to the hotel 🙂 During my stay in San Jose and around there, in Silicon Valley, I will be using a variety of hot spots and I’m told I should have 99% coverage. I’ll be flying back home from SFO to DUB on Saturday and from DUB to BRU on Sunday.

WiFi antenna

I will dedicate a separate blog on each of the experiences and link to each of them from this starting point (this first blog). So expect to see some editing in this piece of text in the future.

Think about Free WiFi (or paid if I really really have to) in places like hotels, airports, a symposium, work, at customer’s sites, in cities, airplanes, taxis, regular cars (I’m getting one with WiFi in it myself in a few weeks)

Enjoy my first, but ongoing series!

Will the new WiFi super antenna change the world?

A Dutch invention will change the WiFi world drastically

At least, that’s what Roel Pieper and Marcel Boekhoorn are convinced of. The revolutionary super antenna should cause all problems concerning the reach of indoor WiFi signals to disappear. Furthermore this new product is supposed to make an end to wireless antennas interfering with each other’s frequencies and smartphones will get a better reception because of this new invention. The new antenna should be better and more advanced than anything else currently known to mankind. On average a smart phone needs about seven different antennas, but with the new invention only a single one is needed. And on top of this using the new antenna more data can be sent and received compared to the existing ones.

Mathematical super-formula

Boekhoorn and Pieper worked together in a company called “Antenna Company”, which will produce these next-gen antennas. The technique is based on a mathematical super-formula made up by Professor Gielis and it’s called the “Super-formula“.

Roel Pieper is appointed as the CEO of the “Antenna Company” and they’re already talking to various multinationals about applying the antenna in cell phones, cars and routers according to the Dutch newspaper “de Telegraaf”. Other applications could be airplanes, medical equipment, weaponry and radar systems, but other equipment that needs to communicate with other equipment, such as central heating thermostats.

World hit

Antenna Company “promises to be my most successful company ever”, according to Boekhoorn in an exclusive interview by Quote. The 3D-optimized antenna can potentially make billions of Euros. “This super antenna will be a hit.” HTC, LG and Samsung are potential customers according to the billionaire. The Antenna Company is already talking to several of these multinationals. Even Cisco is supposedly interested.

High Tech Campus

Production of these super-antennas will start in March. The Antenna Company will settle at the High Tech Campus in Eindhoven in the Netherlands. The Head Quarters is formally located on Curacao. Exactly how much Boekhoorn has invested in the project, he’s unwilling to say..
