2024-10-18 Meshtastic BBS practicality
_ I have compared Meshtastic BBS (TC²-BBS) practicality using LongFast, MediumSlow and MediumFast at SE Portland residential area.
I thought LongFast had advantages because of reach and other nodes hop.
Actually LS was about 0.5 miles practical distance and MS was about 0.9 -1.0 miles practical distance.
The antenna was original and hight was first floor.
That means typical one neighborhood in SE can be covered by one or two BBS nodes.
I also noticed when I used my BBS, the channel utilization went to 30-32% using LF. 15-17% using MS.
MF was about 0.8-0.9 miles practical distance. I also noticed when I used my BBS, the channel utilization went to 3.3% using MF.
LF 0.5-0.8 miles-30-32% util
MS 0.9-1.0 miles -15-17% util
MF 0.8-0.9 miles - 3.3-3.4 % util
_ LF is about 55 active nodes in two hours means about 15-20 % ch util usually. MS and MF both are pretty empty here.
_ All testing points are very few. So this results are just rough impressions base.
_ I noticed LF sometimes need long waiting time to see responses from BBS.
