To get RC and SDC from PC Area Networks (WPANs)

But we can’t get PC from SDC or RC as well as SDC from RC

What do we have so far l.jpg
What do we have so far? Area Networks (WPANs)

  • IBM data  Radio Channel

  • IMST data  Single Directional Channel

  • NICT data  Single Directional Channel

  • NICTA proposed measurements  Single Directional Channel

  • Umass proposed measurements  Single Directional Channel

Su-Khiong Yong, Samsung-SAIT


What are the possibilities l.jpg
What Are the Possibilities? Area Networks (WPANs)

  • Double directional channel is complex and not easy to deal given that we have limited time left and amount of resources we have.

  • Radio channel – We have the data and there are plenty of results to be captured from the literature, see an overview*.

  • Single directional channel – We have the data too and this is the way we should focus and work on it

Single directional channel l.jpg
Single Directional Channel Area Networks (WPANs)

  • SDC CIR can be captured by

    • rotating single antenna in a small interval over 360o,

    • virtual antenna array

    • antenna array

  • With SDC we can take into account for different antenna setups

Su-Khiong Yong, Samsung-SAIT


Different antenna setups l.jpg
Different Antenna Setups Area Networks (WPANs)

  • Based on the data we have e.g. NICT data

    • Typical Home (Japanese living room) LOS

      • Transmitting antenna Omni,  Receiving antenna 15 degree HornVertical polarized wave

      • Transmitting antenna 15 degree Horn, Receiving antenna 15 degreeHorn Vertical polarized wave

      • Transmitting antenna 30 degree Horn, Receiving antenna 15 degreeHorn Vertical polarized wave

    • Typical Japanese Office, NLOS

      • Transmitting antenna Omni,  Receiving antenna 15 degree HornVertical polarized wave

      • Transmitting antenna 30 degree Horn, Receiving antenna 15 degreeHorn Vertical polarized wave

To account other configurations l.jpg
To account other configurations Area Networks (WPANs)

  • The CIRs obtained, deconvolve the CIRs with the original antenna pattern and then convolve with the new antenna pattern.

  • Only applicable to one link end.

Su-Khiong Yong, Samsung-SAIT


Conclusion l.jpg
Conclusion Area Networks (WPANs)

  • We should focus on the single directional channel given that

    • Data availability

    • Less complex than the double directional but more useful than the radio channel for our performance evaluation
