It's a compromise, and flight crew does try to use it this way. That said, consumer devices were regularly found to radiate in all kinds of crazy bands, and would not pass requirements for non-interference in aviation, but pass for home/office environment. The planes where you have wifi internet etc. are certified that they won't have issues with home/office rated equipment. Aviation is really a different regulatory domain and a lot of stuff was designed with the idea that there aren't hundreds of unknowable quality transceivers active in the passenger/cargo area. P.S. The uncompromising option is to pack sedated passengers in pods in racks, and believe me, it's not that uncommon dream among the flight crews.
