  2. Outline • Abstract • Scenario1 • Parameters • Results • Scenario3 • Parameters • Results • Conclusions • Reference Esa Tuomaala, Nokia

  3. Abstract • Simulation calibration verifies that simulators generate the same results on the same simulation scenario • Calibration improves simulations reliability • The presentation shows the calibration results for HEW scenario 1 and scenario 3 [1] with different channel allocation Esa Tuomaala, Nokia

  4. Esa Tuomaala, Nokia Scenario 1 and Parameters • Scenario: • 5 floors building with 20 rooms (10x10x3) per each floor • One AP per each room, x and y randomly chosen, z=1.5 • Same parameters as in [1], except: • Pathlos: 11nB • Wall loss: 12 dB • Floor loss: 17dB + 4dB per floor • TX Power: STA= 15dBm; AP= 20dBm; • 1x1 antenna with 0dBi for AP’s, -2dBi for STAs • Full buffer traffic model • Static MCS7: 64QAM 5/6

  5. Esa Tuomaala, Nokia Simulation Results • The presentation explains and shows results to following metrics: • SINR • Throughput • Number of concurrent transmissions • The results are presented for the following parameters: • Traffic: DL/UL • Number of STAs: 200, 1000

  6. Esa Tuomaala, Nokia SINR • These figures show the CDF of SINR per MPDU containing user data • Left and right figures show SINR performance of 2 and 10 STAs per AP respectively

  7. Esa Tuomaala, Nokia CDF of STA Throughput • Left and right figures show STA throughput performance of 2 and 10 STAs per AP respectively

  8. Esa Tuomaala, Nokia Number of Concurrent Transmissions Statistics • The number of concurrent transmissions statistics shows the number of transmitting devices at the same symbol • This metric does not show the number of successful transmissions • The number of concurrent transmissions indicates the level of channel reuse • The physical and virtual carrier sensing affect to the number of simultaneous transmissions • EDCA parameters, number of competing STAs and traffic amount affect to the number of simultaneous transmissions • The number concurrent transmissions affects to the interference level

  9. Esa Tuomaala, Nokia Number of Concurrent Transmissions • Left and right figures show the number of concurrent transmissions of 2 and 10 STAs per AP respectively

  10. Esa Tuomaala, Nokia Scenario 3 and Parameters • Same parameters as in [1], except: • Pathlos: 11nD • TX Power: STA= 15dBm; AP= 20dBm; • 1x1 antenna with 0dBi for AP’s, -2dBi for STAs • Full buffer traffic model • Static MCS7: 64QAM 5/6

  11. Esa Tuomaala, Nokia Simulation Results • The presentation explains and shows results to following metrics: • SINR • Throughput • Number of concurrent transmissions • The results are presented for the following parameters: • Traffic: DL/UL • Number of STAs: 570
