That is not uncommon to planning projects :-) I was paid to run such
loops for several years...
But having the loop here ist much better that after step 16.

That are all good options for a GTA02+ path.
For a GTA03 there is a quite different approach - glue together PDA
and UMTS modules and a Battery. There are some quite interesting PDA
reference designs or modules on the market.
That may be a little more expensive in terms of BOM but saves a lot of
money in the area that we currently don't have: detail engineering.
