with respect, iridium is not low power. even the small "IoT" modem https://www.iridium.com/products/iridium-core-9523/ https://www.iridium.com/products/iridium-core-9523/ requires 2.5 watts peak. even once a day, you're lucky to get a months worth of reports from anything less than 10whr battery.
Especially if you are in an urban/sky contrained environment.
- diamondo25 8y agoWe are not running on Iridium, but our own satellites and frequencies.
- KaiserPro 8y agosorry yes, I should have read this first: https://support.hiber.global/hc/en-us/article_attachments/360003823774/HBR-DS-18003_LPGANmodem-shortForm_v1.1.pdf https://support.hiber.global/hc/en-us/article_attachments/36... transmit is on average 4.1 watts. I get that for satellites that's pretty low power, but that's still in the order of 30dbm (assuming losses). compare that to the peak of 23dbm for LTE-m or 14dbm for lora. Now the OP author doesn't seem to grasp that the reason bluetooth le can last so long/update so much is because its got a limited range. Hiber at a minimum has to reach 600km, more when the satellite is not directly above. LTE-M only has to reach a few KM at best, lora has tiny packets with low duty cycle.
