2 Submission doc.: IEEE 802.11-15/0340r1March 2015 Alecsander Eitan, QualcommSlide 2 Motivation and purpose In this presentation we present LOS/NLOS channel measurements in cubical environment We would like to learn the existing channel looking forward to 11ay

3 Submission doc.: IEEE 802.11-15/0340r1March 2015 Alecsander Eitan, QualcommSlide 3 Setup Test have been performed using two commercial Dell PCs running Linux Both recording HW and antennas are the same as provided in the product (32 antenna elements per array). Beamforming was done by the FW in the product itself. No interference during the measurement Test have been done with high SNR (EIRP>= 19 dBm) Channel estimation is based on the Golay correlators in the modem, running at 1.76GHz

4 Submission doc.: IEEE 802.11-15/0340r1March 2015 Alecsander Eitan, QualcommSlide 4 Environment Two Laptops

5 Submission doc.: IEEE 802.11-15/0340r1March 2015 Alecsander Eitan, QualcommSlide 5 Position 1 LOS case Reflection is stronger than LOS due to rotation Trms=2.5 ns (AP), 1.9 (STA)

6 Submission doc.: IEEE 802.11-15/0340r1March 2015 Alecsander Eitan, QualcommSlide 6 Position 2 LOS case 1 meter, boresight to boresight Trms=2.4 ns (AP), 1.3 ns (STA)

7 Submission doc.: IEEE 802.11-15/0340r1March 2015 Alecsander Eitan, QualcommSlide 7 Position 3 LOS case <1m, boresight to backside. LOS clearly seen. Trms=1 ns (AP), 1 ns (STA)

8 Submission doc.: IEEE 802.11-15/0340r1March 2015 Alecsander Eitan, QualcommSlide 8 Position 4 NLOS case 1 meter, boresight to boresight. Trms=1.8 ns (AP), 1.8 ns (STA)

9 Submission doc.: IEEE 802.11-15/0340r1March 2015 Alecsander Eitan, QualcommSlide 9 Position 5 LOS case AP on the wall, PC on cubicle. LOS is available Trms=3.5-4 ns (AP)

10 Submission doc.: IEEE 802.11-15/0340r1March 2015 Alecsander Eitan, QualcommSlide 10 Position 6 LOS case AP on the wall, PC on corridor LOS is available Trms=1 ns (AP)

11 Submission doc.: IEEE 802.11-15/0340r1March 2015 Alecsander Eitan, QualcommSlide 11 Position 7 LOS case AP on the wall, PC on corridor (far) LOS is available Trms=1.6-2 ns (AP), 2-2.6 (STA)

12 Submission doc.: IEEE 802.11-15/0340r1March 2015 Alecsander Eitan, QualcommSlide 12 Position 8 LOS case AP on the ceiling, PC in cubic LOS is available Trms=1.5-1.2 ns (AP), 2.1-2.3 (STA)

13 Submission doc.: IEEE 802.11-15/0340r1March 2015 Alecsander Eitan, QualcommSlide 13 Position 9 LOS case AP on the ceiling, PC in cubic LOS is available, boresight to boresight Trms=1.7-3.5ns (STA)

14 Submission doc.: IEEE 802.11-15/0340r1March 2015 Alecsander Eitan, QualcommSlide 14 Position 10 LOS case AP on the ceiling, PC in corridor LOS is available, boresight to boresight Trms=3-4 ns (STA)

15 Submission doc.: IEEE 802.11-15/0340r1March 2015 Alecsander Eitan, QualcommSlide 15 Position 11 LOS case AP on the ceiling, PC in cubic below LOS is available Trms=1.8 ns (STA), 1.4-1.8 ns (AP)

16 Submission doc.: IEEE 802.11-15/0340r1March 2015 Alecsander Eitan, QualcommSlide 16 Position 12 LOS case AP on the ceiling, PC is person height LOS is available Trms=1.5-2 ns (STA), 1.8 ns (AP) Far from ladder

17 Submission doc.: IEEE 802.11-15/0340r1March 2015 Alecsander Eitan, QualcommSlide 17 Summary Measured Trms range: 1-4 ns MMSE EQ degradation is expected to be 3-11 dB for LOS channels The NLOS channel tested had the same EQ degradation and the same delay spread (Trms) as the LOS channels (Perhaps due to diffraction taking the lead) We suggest to compare the 11ad measured channels with 11ad model to validate the model looking forward to 11ay.
