Box-5 Calibration [1]
Box 0, 1, and 2 calibration are almost done
Box 3 calibration is now in progress
Box 5 calibration was initially discussed in September meeting
Box 5: Integrated system simulator calibration
The objective is to align a combination of all PHY and MAC features

4. Box-5 PHY Details [2] May 2015 PHY parametersBW
All BSSs at 5GHz [80 MHz, no dynamic bandwidth]
Channel model
TGac D NLOS per link
Shadow fading
iid log-normal shadowing (5 dB standard deviation) per link
Data Preamble Type
[5GHz, 11ac], always decoded correctly after successful reception, duration is considered.
STA TX Power
15 dBm per antenna 
AP TX Power
20 dBm  per antenna
AP number of TX/RX antennas
1/1
STA number of TX /RX antennas
AP antenna gain
0 dBi
STA antenna gain
-2 dBi
Noise Figure
7dB
CCA threshold
-56 dBm (measured across the entire bandwidth after large-scale fading)
Rx sensitivity
-76 dBm (a packet with lower rx power is dropped)
Link Adaption
Fixed MCS =5 (234.0 Mbps)
Channel estimation
ideal
PHY abstraction
RBIR, BCC [1, 5]
Channel correlation
Independent or time-correlated channel per packet

5. Box-5 MAC Details [2] May 2015 MAC parameters
Access protocol
[EDCA, AC_BE with default parameters] [CWmin = 15, CWmax = 1023, AIFSn=3 ]
Queue length
A single queue for each traffic link is set inside AP/STA sized of 2000 packets
Traffic type
UDP CBR with rate 10^8bps (may not enough to model full buffer)
MPDU size
1540 Bytes (1472 Data + 28 IP header + 40 MAC header)
Aggregation
[A-MPDU / max aggregation size / BA window size, No A-MSDU, with immediate BA], Max aggregation: 64 MPDUs with 4-byte MPDU delimiter
Max number of retries 10
Beacon
Disabled
RTS/CTS
OFF
Traffic direction
UL Only
Output metric
-CDF or Histogram of per non-AP STA throughput (received bits/overall simulation time)
-PER of all AP/STA (1 - # of success subframes / # of transmitted subframes)

7. History on Box-5 Calibration
May 2015
History on Box-5 Calibration
We have discussed Box-5 calibration from September meeting
Many issues have been agreed and addressed in DCN 1523r5
However, we still found big performance difference among members
Simulator members agreed that we have to focus on 1 BSS UL case in March meeting (BSS B)

8. Focusing case No shadowing Fixed MCS = 5 instead of 7 currently used

Focusing case
No shadowing
Fixed MCS = 5 instead of 7 currently used
Firstly calibrate 3 combinations of 2-STA case (3+9, 3+27, 3+15)
Then we turn to 3-STA case (3+9+27, )
