Hello, I’m interested in the idea of a free and open source phone, but I would like to learn more about the exact level of freedom it has. On the wikipedia page about currently existing “open source” phones, https://en.wikipedia.org/wiki/List_of_open-source_mobile_phones it is said: All availa…

Then I am at least wondering if the developers of purism are at least considering as an option to recover the apparently abandoned OsmocomBB? Or is that impossible for some reason?

[image] lamerator2018: Or is that impossible for some reason? Yes. Because GSM is being phased out in North America (dunno about other regions). Just search “gsm alarm sunset” and see for yourself; Alarm companies (first phase) are already alerting their customers. In a few years, you’ll not …

The future, in Canada at least, is going to be LTE. Carriers go with what’s cheapest. By future I mean like in 5 years.

Just for the records, the idea to develop a free baseband firmware is deeply rooted in our development and research. At the moment this goal is not feasible to target since there is too little information out there on existing chips and too little existing software to base on. To do everything from …

I am not disappointed with their decision (not custom develped baseband, but maximum separation from CPU/RAM). As it’s still the most secure and feasible solution on the market (the current situation is just a terrible risk from the security POV).

From what I’ve seen (see Harald Welte’s 33C3 talk ( video , slides ), also a Sierra Wireless press release and some reading on the Option modem which the GTA04 used), there are several vendors who basically stick a wrapper around a Qualcomm modem and package that out as a complete system. What this mea…

[image] nicole.faerber: To do everything from scratch would take way more than the money that we will have at hand for development (please keep in mind that the campaign money also has to pay for the devices, not only the development). I don’t know for sure, but it seems to me that a project …

[image] nicole.faerber: What I want to assure to you is that we will do all and everything we can possibly do within the constraints we have to build a device that is as free/open and as transparent as possible. And we also think about its future, i.e. that the parts that might not be free from …

[image] lamerator2018: “to develop from scratch and build a new baseband chip with fully open specifications and firmware” would attract much more money from the community. You may attract more attention by going “whole-hog”, but then, hypothetically but very likely, your timeline to completi…

[image] lamerator2018: I am still a bit surprised how counterintuitive the development of a new mobile network chip looks for you. Qualcomm builds these chips, plenty of other companies build their own (“commercial” as you say) chips for GSM/WiFi/Bluetooth, why should it be impossible for Purism…

Todd Weaver talked for several minutes about the baseband, regulation, possibility to free it, etc. in a recent interview with UBports.
