Tentative, subject to change.
2022-01-04
Our first lecture will be on Thursday, January 6 at 1:30 PM in a Virtual Classroom.
2022-01-14
Lab 1 is available and will start next Tuesday (January 18). Set S will do the lab the first week and set T will do the lab on the second week.
You may do the lab at home if you can install the GNU Radio software your own computer. If you install the software on a laptop you will be able to use it in a future lab involving propagation measurements.
2022-02-21
As per the course schedule, there is no lab this week. The due date for Lab 5 (IoT) has been corrected to March 8.
2022-02-23
The final exam for ELEX 7860 will be on Friday, April 22 at 14:30 (14:30 to 17:30) in SW03-1750.
2022-03-02
The second midterm exam will be held on Friday, March 4 at 10:30 in SW1-3150. It will cover lectures 1 through 3 (primarily multipath propagation, LOS path loss and NLOS path loss). The lecture notes have been updated to include learning objectives, which are the specific things you may be asked on the exam. Previous exams are available on my course materials archive site.

Unfortunately, the version of the NLOS Propagation lab that we used yesterday did not ask you to measure distances to the transmitter and so you may not be able to estimate the path loss exponent.
A floor plan for the third floor of SW1 at a scale of 1:500 is available and can be used to estimate distance to the transmitter (d). A sample from last year's lab is:
If you began your measurements outside the door to the lab, a reasonable starting distance might be 3m. A reasonable ending distance (where the signal drops into the noise) might have been 30m. This is one decade of distance. If you estimate the range of signal levels in dB (20log(voltage)) over this range of distances (e.g. by looking at the average signal levels around these points) then the path loss exponent will be one tenth of the difference in dB between these signal levels.
For example if the signal levels in dB at 3m and 30m were -40dB and -60dB respectively then the path loss exponent would be (-40-(-60))/(10log(30/3)=2. The estimate of the path loss exponent is relatively insensitive to errors in these measurements (at least, relative to the variability of the underlying parameter). Use your own measurements in your report.
A revised version of this lab is available.

There was a proposal to change the marking scheme for the course from:
MT = ( MT1 + MT2 ) / 2
to:
MT = ( max(MT1,MT2) + max( min(MT1,MT2), FE ) ) / 2
where MT1 and MT2 are the midterm marks and FE is the final exam marks (all converted to percentages). The effect is to replace the lowest midterm mark with the final exam mark if the final exam mark is higher than the lowest midterm mark.
Because this change is being proposed so late in the term, I will not make the change unless there is near-unanimous agreement.
Please let me know by e-mail me if you would like to retain the previous marking scheme rather than this one.
2022-03-28
Quiz 3 will be on Friday, April 1 as scheduled. It will cover Lectures 4 (Diversity), 5 (Capacity), 9 (IP3) and 10 (Noise Figure).

Congratulations, everyone passed the course.
The final exam has been marked and emailed back. The solutions and the marking scheme have been posted. Let me know as soon as possible if you have any questions.
The unofficial final marks have been computed but are subject to change.
The distributions of the final exam marks and final course marks are shown below.
