Bus Shelter Install Notes ========================= DHD20160301 LoRa range-test run. Installation crew: Damon HD & Deniz E. Sensors: 1) b9f9 LoRa (node 04) REV14 3) c2a1 LoRa (node 22) REV14 8) b5ac LoRa (node 20) REV14 Observations during install: * (1) Replaced, in seat void. (TX success rate similar to eaves void.) * (3) Placed in timetable flag near Shoreditch LoRa node. * (8) Removed: battery still at 2.54V, ie had not run down in a week with QM-1 powered down, so probable 2+ week life even without LoRa module sleeping correctly. Had a great deal of trouble getting any LoRa module to TX to antenna more than ~200m away, though line of sight was not necessary, ie not instant radio shadow when on other side of building from base station. Also having trouble making LoRa modules accept config for lower data rates (and higher spreading factors). 2016/03/02: with lower data rate and larger spreading factor may have achieved from DigiCat to Doubletree Hotel on Penton Rise ~1.3km. (Maybe 30%--50% further that the ~0.9km to Calshot St junction yesterday.) Higher spreading factors / lower data date seem to be a good idea.
