Layout for the 2-PCB design has been completed, but has not yet been reviewed.
See Monday’s presentation for review.
2-revision timeline remains on track to ensure any mistakes can be remedied.
Preliminary range testing with the 2.4 GHz “9” dBi dipole antennae and Wi-Fi XBees proved successful at ~250 m, but it was likely not representative of our target environment. Furthermore, longer-range testing was inconclusive.
Currently looking into whether or not CMU has a suitable RF chamber for our testing purposes.
More range testing will occur when the system has been further realized.
A 2.4 GHz “19” dBi directional dish antenna has been acquired (c/o Carnegie Tech Radio Club), and will be tested.
Risks that have been resolved as of this week’s entry:
Partially resolved the above issues from last week, but as indicated, further mitigation is required.
Design changes
No design changes have been made.
Updated schedule
No updates: We’re still on schedule in terms of PCB schematic and layout, as well as firmware bringup and implementation. (See our Gantt chart for more details.)
