Turn your device to landscape mode

For the best experience,

Ready

IoT devices are under attack!

Interference monsters are disrupting coexistence between devices in crowded wireless environments where they need to operate. Use your K.E.Y.sight goggles to locate the interference monsters in 3 different wireless settings, and bring coexistence to these IoT devices so they can work as expected.

Tutorial

This tallies your total score, based on how many interference monsters you are able to identify and eliminate.

The progress bar tracks how many monsters- and bosses- you have left. Bosses are marked in orange.

Every monster you fail to take down damages your shield- be careful not to lose your last shield, or you’ll be taken out of the fight!

Hunt monsters with your cursor- when you get close, they'll display a telltale glow and the icon below:

Around dinnertime each night, your laptop connection gets very slow. What might be the cause?

All of the above

Those new LED lightbulbs you installed in the kitchen are emitting interference noise signals when they are turned on.

The nearby airport has a lot of aircraft landing and your router has to find new channels to use.

The microwave oven interferes with your WiFi router signal.

For an IoT device to operate as intended, it must coexist with other devices. Coexistence is the ability of an IoT device to operate in the presence of other devices or wireless equipment using dissimilar operating protocols or standards.

When you visit your friend in the hospital, an alarm from a medical device in the room sometimes goes on, even though it is not triggered by an actual medical event. How can you help avoid this?

All of the above

Wear heavier coats to shield your body

Remove your jewelry

Turn off your smartphone

In the wireless coexistence section of the document, “Radio Frequency Wireless Technology in Medical Devices and Guidance for Industry and Food and Drug Administration Staff” issued on August 14, 2013, the FDA specifically recommends that you address your device’s environmental specifications and needs including which of the following? (Check all that apply)

Associated sources of EMD expected in specific known use environments

Co-channel interference from medical devices and other users of the RF band

Non-ionizing x-radiation emitted from imaging equipment

Unanticipated hostile actors intent on disrupting medical device performance

Adjacent channel interference from medical devices and other users of the RF band

Which technique is commonly used to improve coexistence of IoT devices and networks?

As more smart devices are added to your building, they begin to get less reliable. What may be the cause?

All of the above

There are too many devices in a small place to handle all the data traffic

Other infrastructure (wireless keyboards and printers) interfere with the smart building sensors

They use different wireless protocols and interfere with each other

Which of these techniques can be used to mitigate in-band coexistence challenges in industrial IoT applications? (Check all that apply)

Medium access control (MAC) scheduling

Adaptive frequency hopping (AFH)

Statistical ripple control (SRC)

Interference-aware packet scheduling

Direct sequence spread spectrum (DSSS)

Time-division multiple access (TDMA)

When configuring your test equipment for coexistence test, the set up you implement will depend on

Whether or not your device will operate in a Multiple-Input Multiple-Output (MIMO) network

The spectrum analyzer you use

Competing network devices

Your Device Under Test (DUT) and the device that connects or pairs with the DUT

All of the above
