We’re big fans of WiFi. This shouldn’t come as a surprise since WiFi, just like Airtame, is a cable killer. But what do you actually know about WiFi? Take a look at all of these awesome WiFi facts we’ve compiled and check if you’re up to date.

1. WiFi could be older than you are

The group that would develop IEEE 802.11, later marketed as WiFi, met up to discuss the shape of the invention in September 1990. That’s almost 30 years ago.

2. The name doesn’t actually mean anything

You might have heard of the IEEE 802.11, but if not, here’s a recap: IEEE 802.11 refers to the set of standards that define communication for wireless local area networks.

IEEE stands for Institute of Electrical and Electronics Engineers. The number 802.11 refers to the methods and protocols of sending network information without any of the annoying cables. In short, it’s pretty geeky stuff.

It’s not a very catchy name, so with the help of a brand-consulting firm, the technology was instead marketed as ‘Wi-Fi’ in 1999. WiFi doesn’t actually mean anything, but we can all agree it’s a lot easier to remember. It is not, as commonly thought, an abbreviation for “Wireless Fidelity.”

The original term was ‘Wi-Fi’ with a hyphen, but like most hyphenated words, the use of the punctuation mark dissipates in time when the phrase is taken into common parlance. We like WiFi, but if you’re a bigger fan of Wi Fi or wifi, you’re (wi)fine too!

3. There are more than 9 billion WiFi devices in the world

It was estimated that more than 9 billion WiFi-enabled devices would be in use worldwide at the end of 2017. That number is likely a lot higher now, just a year later. But it makes sense. Just think about the different devices you have – and you probably have more than one.

4. WiFi uses radio waves

Let’s start with the basics. WiFi is a technology that uses radio waves to transfer information from one electronic device to the other. It’s what makes it possible for your computer to access the internet – without cables, which is the best fact of them all to us.

5. WiFi is very susceptible to interference

There’s nothing more frustrating than trying to stream a movie that keeps buffering, right?

The drop in your signal strength could be caused by interference. WiFi uses radio waves to send a signal, but they often bump paths with other radio waves at similar frequencies. With 9 billion WiFi devices in use, that’s no surprise.

Some of the sources that cause interference with WiFi networks include smart TVs, microwaves, cellphones, Bluetooth-enabled devices or even a fish tank. Different barriers may also cause interference, but whereas wood isn’t too bad, metal is sure to stop your signal.

6. Reduce interference by unplugging other devices

Your WiFi likes to be the only power in play, at least when it comes to interference.

Reduce interference by turning off and unplugging electronic devices such as TVs, Bluetooth devices, printer, baby monitors – and that microwave of yours as well! You could also change channels on your wireless network or move your WiFi closer to the computer.

7. The best WiFi blocker is YOU

Water is a great signal blocker. Seeing as you’re made up of 75% water, if you’re sitting between your router and your computer, your body can significantly lower the strength of your WiFi signal. Good thing you’re not made of metal though because as we specified above, metal is a better blocker than both wood and water.

8. Doughnut-shaped signals are a thing

If you have an antenna on your router, the radio frequency energy that radiates from it looks a lot like a doughnut. In reality, you can’t really see a doughnut protruding from your router, but the thought of a doughnut-shaped energy field sounds delicious, right?

9. WiFi frequencies are different

WiFi transmits at frequencies of 2.4GHz or 5GHz and the frequencies for WiFi are much higher than those for cellular transmission. Higher frequencies, in short, mean that signals can carry more data.

Generally speaking, you give up range in exchange for more data, and that’s amazing if you care about digital signage. What would you choose?

10. WiFi is more important than breakfast

Speaking of doughnuts, breakfast is the most important meal of the day. So our parents have told us. Red Roof Inn, the US hotel chain, conducted a survey together with Research+Data Insights that asked 800 economy travelers how important different amenities are to them.

The survey concluded that in-room WiFi is more important to travelers than good location, parking or even complimentary breakfast. 80% of the travelers even stated that they would feel more amicable towards a hotel if complimentary WiFi is included.

So if you plan to open a hotel any time soon, remember that high-speed complimentary WiFi will convince guests easier than oceanview or a tasty brunch.

11. There are several different kinds of WiFi

Alright, so we taught you earlier what 802.11 means, but there are actually several other versions out there. The original is from 1997 and not in use anymore, but since then we’ve had 802.11b, 802.11a, 802.11g, 802.11n, 802.11ac, and 802.11ad.

It’s quite an alphabet soup to digest, but we can say that in general, newer versions are backwards compatible with older versions, but not the other way round. For newer versions, there are several things to consider such as speed, range, and cost.

12. WiFi originated in Hawaii

Well, sort of at least. Not everyone agrees with this fact, but the fact still remains that an early predecessor of WiFi was launched in 1971 in Hawaii and was called The ALOHAnet. It was a pioneering computer networking system developed at the University of Hawaii.

Two decades later, NCR Corporation and AT&T Corporation invented WaveLAN, which is considered the true precursor to WiFi. In 1997, the first version of IEEE 802.11 wireless protocol was released.

While we agree that there’s some controversy surrounding this fact, we don’t have anything bad to say about the name ALOHAnet.

13. Lithuania has the fastest WiFi

You probably wouldn’t have guessed that, right? Well, according to Rotten Wifi, Lithuania has the fastest WiFi in the world at 16.6 Mbps as per November 2016. The Baltic region country tops the list over Singapore (15.1), Switzerland (13.8), Denmark (12), and the United Kingdom (11.7). The United States ranked 19th.

14. IoT and WiFi aren’t a perfect match

The Internet of Things or simply IoT is the concept of connecting all things in the world to the internet. For some IoT applications like in-house energy management, surveillance or home appliances, WiFi works just fine.

But that’s not the case with all IoT applications. Standard WiFi (based on 802.11a/b/g/n/ac) has some limitations in both range and energy efficiency. So in home environments or campuses where there are power outlets for all IoT applications, WiFi is still a go-to choice.

Other areas such as outdoors will require a more IoT-friendly connectivity. But who knows, maybe that’s already underway?

15. Free WiFi for all EU citizens could be happening

WiFi4EU (what a catchphrase!) is a project by the European Commission that offers vouchers worth €15,000 for EU municipalities to set up WiFi hotspots in public spaces. These include libraries, parks, and museums among others. But don’t take our word for it:

We propose today to equip every European village and every city with free wireless internet access around the main centers of public life by 2020

Jean-Claude Juncker, President of the European Commission

If EU municipalities decide to benefit from this particular EU funding, every European city could have free WiFi soon. So now you know where to travel next.

The post 15 things you didn’t know about WiFi appeared first on Airtame.

Already set up and ready to go wireless? Download the Airtame app directly from your computer.

1) Setting up and powering Airtame

Plug Airtame into the HDMI port on your TV or projector. Use an adaptor if there’s no HDMI input. Use the included AC adaptor to ensure Airtame has power or alternatively power Airtame through the TV via the micro-USB to USB cable. You will only be able to set up Airtame through a computer, as you need access to the Device Management Panel.

2) Placement for best stability and performance

If your WiFi signal is blocked, your streaming performance may be inhibited. Make sure that the AIrtame is placed as close to the edge of the TV as possible and preferably pointed towards the nearest access point. The distance from the access point to Airtame should be no more than 10 meters/32 feet, and with no WiFi blockers in between.

3) WiFi or Ethernet connection

Airtame relies on a good connection to stream without interruptions. We recommend using an Ethernet connection between Airtame and the network for optimal performance and minimal delay.

Many of the obstacles found with WiFi are not adherent with Ethernet. If you’re using a WiFi connection, however, make sure to limit the number of obstacles in between Airtame and the network, as described above. Remember that walls, other access points and physical objects will impair the connection.

Before setting up Airtame, we suggest to map out where your access points are and how your Airtame will be set up in relation to them. If you’re unsure whether your WiFi signal is strong enough to carry a good connection with Airtame, use a signal strength app or go to Airtame Cloud to check it.

4) Access and installation

We’ve made installing your Airtame as easy possible. Once you have plugged in the device via the HDMI port, select the correct HDMI input on your TV or projector. You’ll be presented with a welcome screen, and asked to visit airtame.com/setup to download the Airtame app to your laptop or computer.

Once the app is installed and launched, just follow the simple set-up instructions: name your Airtame, and connecting it to your preferred network.

5) Get the most out of Airtame Cloud

Go to https://airtame.cloud/ and set up a fee Airtame Cloud account. Add the Airtames in your organization It’s your cloud management tool where you can manage and monitor all of your devices.

In addition, you’ll be able to select the content shown on screens when no one is streaming to Airtame. Create groups of devices and set permissions in the Cloud, perform reboots or update chosen devices. In the cloud, you’ll see Homescreen. That’s your screens when Airtame is idle.

With the newest firmware update, you’re also able to customize Homescreen to show images, websites, custom backgrounds or app integrations. Currently, we offer these four app integrations for Homescreen: Trello, Unsplash, World Clock and Google Slides. They’re perfect for digital signage purposes, something we believe every business can benefit from exploring and utilizing.

Invite other users by clicking on “Invite user” in the upper right corner of the Cloud and entering their email. In the overview of users, your coworkers will now show up.

You can set-up your colleagues as any of the three user roles: Administrator, Manager and User, each featuring different levels of maturity and access to the Cloud. If you need to remove a user, you can do so by going to the “Team” tab and removing the person.

6) Set up more than one Airtame

Mass deployment to more than one computer is also possible. For Windows users, download a mass deployment installer here to pre-configure and install on many PCs.

For Mac OS, use a third party deployment service along with the existing .dmg file along with Soundflower for audio capturing. The Soundflower driver is included in the .dmg package, but for mass deployment you need to install it separately.

Here’s some more general points about mass Airtame installation and deployment in business environments, and here for schools.

7) Calibrate your display ?

Pre-set image settings on most TVs and projectors work best with watching satellite TV. To improve image quality when streaming, you can calibrate your screen to best fit Airtame. Adjust screen settings by opening a blank spreadsheet document for color reference.

Find standard mode or reset adjustments on your screen and reduce contrast (often around 70-80% of max value) until all lines in the spreadsheet are visible. Reduce sharpen until the text is easy to read (often 0-20% of max value). See more tips on how to adjust display settings here.

8) Troubleshooting

If a problem should occur either with the connection, updates or other, we recommend first checking the source of the problem. If you have no connection, check your WiFi signal. With update issues, you should look at your firewall restrictions.

We also have a help center with many useful articles on troubleshooting and getting the most out of Airtame. If you aren’t able to fix the issue yourself, we’re always ready to assist you. Go to our website and chat directly with one of our competent Customer Success team members by clicking the chat icon in the bottom right corner.

9) Customize your Airtame settings

There are many ways you can personalizing Airtame for your workplace. Beyond the digital signage options outlined above, you can find the many settings for your device(s) in the Airtame app, such as framerate (Frames Per Second) and buffer time. You can even download your log files if you need to troubleshoot, and contact us directly via the chat functionality.

 

10) Audio and video streaming

Click the sound button in the Airtame app to enable audio. Audio is disabled by default to minimize latency, but with a stable connection, you can stream both audio and video with sound.

11) Setting up guest networks

Creating guest networks within your internal networks is not only smart for security purposes, it’s great for organizations with a steady flow of guests too. We also offer a Windows Guest app for one-time users so they don’t have to install the regular app.

We’ve created a list of network configurations and requirements to accommodate internal and guest users. See more recommendations for Airtame and guests here.

The post 11 important steps to consider for your first Airtame installation appeared first on Airtame.

1. Plugging in a cable is less complicated

We don’t think so. Haven’t you ever been in a corporate meeting or a study project presentation where the presenter had to detangle a spaghetti monster of cables? The frustration of having to detangle cables, find suitable adapters or having to set up early to test is common. Setting up a wireless screen sharing solution may require a few additional steps, but once completed, it works both quicker and easier because you only have to click one button.

2. Picture quality is poor

That depends on the device. It’s true that for the best video streaming quality, a cabled connection is better. In most business or education environments though, heavy video streaming is not as important, if at all. Perhaps you’re experiencing delay rather than poor quality, and this is quite normal. A small amount of delay will not interfere with your work or presentation, and it doesn’t mean that the quality is bad. Everything has delay, even HDMI cables, but with a cabled connection it’s less than what a human would likely be able to detect. The average reaction time for humans to a visual stimulus is 0.25 seconds, and delay is generally below that. Delay is mostly dependent on the network, so if the network is fast, your wireless solution probably is too.

3. It requires something to be attached to the computer

No, not always. Some solutions, like ClickShare, have stuck to a more traditional way with devices also attached to the computer, maybe because it felt more intuitive earlier on. But more and more software solutions that use the wireless hardware already built in to the laptop or mobile device have surfaced. Like Airtame 2, that means you only need a receiving device.

4. Wireless screen mirroring uses Bluetooth

Nope, that’s not possible. Bluetooth only transmits very little data per second, not enough for screen mirroring.

5. A good internet connection is a good network for wireless screen mirroring

That’s not necessarily the case. When we mirror screens wirelessly, it stays within our network and never reaches the internet. Think of the internet as one big network and your network as a smaller, local one. Screen mirroring quality is mainly based on your network’s performance, and Airtame 2 supports both WiFi and Ethernet.

Generally speaking, Airtame 2 is not very “bandwidth hungry”, as our optimized streaming uses only very little bandwidth. Dropouts or long responsive times will however have an impact as this will cause the image to freeze or jump.
