&gt; I spent most of my career as an engineer working on R&amp;D for software that would likely sit in a baseband in a production implementation. We spent millions of dollars building it, and nothing comparable is publicly available. The secret sauce in a baseband is definitely the sort of thing that&#x27;s in short supply.<p>A lot of those millions of dollars are because you have crappy processes, crappy tools (&quot;rational&quot; ones for example), base-level engineers (with some exception) and stupid management<p>I bet most of your &quot;secret sauce&quot; is mostly application of Computer Science 101&#x2F;201<p>I know, those softwares are complicated. But I&#x27;m not feeling sorry for most big companies who like to justify cost with their own crap dragging them down<p>(And yeah, I know, telecom protocols are awful)<p>That&#x27;s why Android and Apple wiped traditional phone companies
