Thank you @tony-white & @williangalvani!! We (finally) did a Blueboat mission using 4G connection with ZeroTier (+ Ping2 and Cerulean 450 SS). I think this mission will take longer to finish should we only use the standard BaseStation setup.
We put a Huawei E5577 (mifi hotspot) inside the starboard hull’s electronic tray. The modem has 2 antenna slots, we connected each of the slot to a Bingfu 4G LTE Antenna (as per this post & they do fit nice through the M14 holes on the hatch lid). BlueOS auto-connects to the modem everytime it turns ON.
