Observations (details started to emerge last year with a basic Sony run operator service in pilot deployment in Tokyo since last Sept) -
YAPLPWAN (Yet another proprietary LPWAN offering! 
)
@~80bps and with focus on bubble-up (uplink centric) apps more a competitor to Sigfox than LoRa/LoRaWAN?
Offered in a (16mm x 16mmx2mm 65pad LGA) SIP/Module c/w GPS/GNSS receiver and MCU
Based on a BPSK RF modulation variant but also with a sub-modulation based on a linear chirp
Signal resiliance based on similar mechanisms to Sigfox and BlueTooth with the same data being repeated (decreased battery life/increase uJ/message?) with 4x repeat (BT & Sigfox use 3x repeat IIR) (~1.6s for 128bit payload?)
Initially targeting Japan market and freq bands - local approvals in place and also now an ETSI substandard? (TS 103 357 “Lfour Family.”)
-142db Rx sensitivity with 20dBm Tx available, LDPC Error correction built in
Carrier Sense for LBT tx?
