The mentioned in the announcement developing a very efficient data codec for text compression, I'd presume something Binary and not over TLS, just raw data packets probably with some encryption
- oneplane 4y agoI'm sure the Apple use case is different from a web api, but it was more for illustrative purposes. I imagine most developers know how to wrap data in JSON and how to do a HTTP call over TLS. When using that as a point of reference, having such a transmission take a long time might show how little bandwidth some M2M networks have (or need). I wouldn't be surprised if the current Globalstar network is so limited it wouldn't even do voice.
- kylehotchkiss 4y agoThey support voice (https://www.globalstar.com/en-us/products/voice-and-data https://www.globalstar.com/en-us/products/voice-and-data), it's my understanding that it's analog and not digital though, like a really narrowband landline phone call
- oneplane 4y agoThat makes sense. Satphones are probably using that same super low symbol rate used by M2M.
- noway421 4y agoGiven that they're transmitting an app form over to Apple's server, they could encode checkboxes with bitmaps and text fields with dictionary LZMA. There probably will be only a few bytes of the actual data per emergency submission + protocol authentication and error correction overhead.
