Yes, that's what we could do initially, it's not something we need
urgently. The discussion is whether we should consider this for some
later revision of UmTRX.

The concern about a separate PoE splitter is that it might reduce
overall system reliability. OTOH, it's easier to replace a broken
separate PoE splitter then replace the whole UmTRX if built-in PoE is
broken. AT the same time, separate PoE is more expensive and require
more space. Thus it's not clear to me whether a built-in PoE would be
a benefit or not.
