This shows some applications of DecaWave's ScenSor IC, an IEEE 802.15.4a UWB (ultra wide band) standard compliant RF (Radio Frequency) transceiver that enables precision RTLS (Real Time Location Systems) applications. The ScenSor is also applicable to Wireless Sensor (Mesh) Networks (WSN) where it delivers higher-speed and lower-power data transfer compared to other 802.15.4 PHY implementations as used by ZigBee, 6LoWPAN, and proprietary WSN. The ScenSor enables thing-to-thing (T2T) communications bringing the vision of an Internet of things (IoT) closer to reality.

In the video:
(1) Precise distance measurements are used to determine proximity and... (a) enable/disable devices (LapTop), (b) find lost items (Laptop and Teddy Bear), (c) enable access (opening door for doctor), (d) identify nearby patient info and so download correct records to doctor, (e) advise of approaching friends....
(2) An in-store location application guides shopper to the goods she desires
(3) proximity of tagged clothing, prompts suggestion of available matching shoes.
(4) Information transfer capability is seen as patient data is loaded.

Items are tagged with active RF devices using the ScenSor transceiver. This allows precise times of message sending and arrival to be measured, from which the time-of-flight can be calculated to yield a distance accurate to 10cm between peer devices without any other infrastructure.

With a fixed infra-structure of "Anchors" in a shop, factory or warehouse, range measurements can be combined to yield 3D location, or, with synchronised Anchors, TDOA (Time Difference of Arrival) can be used to locate items whose tags simply transmit an identifing blink message periodically. This is a low-power solution allowing operation with a small coin size battery for many years or perhaps indefinitely using energy-harvesting technology.

  • Wow this looks really good!

  • Ideal for stalking

  • Wahat if I don't want to be found? Like at 2:14

  • Stupid teddy-bear causing the Internet of Things !!!

  • so what are u guys using rfid or some zigbee type sensors

  • Nice movie! It doesn't really show the technology. But it's an excellent summary about what type of applications a consumer can expect in the "near" future.

    And what about civilian-government applications, or service providers, or energy management, etc. It would be nice to find the proper manner to introduce it to the market. A quick win with a lot of money.

    That's I think the main issue that need to be highlighted, what's the amount of money people are gonna save with this new technology?

  • Well done very good I would definitly be intersted in this!

  • Oh, it seems to be too much of technology...

  • wow thats so cool
