the industry is still not sure how much actual savings will happen in going with Apple's "royalty free" promise if TS102 221 selected the Apple proposal (Nokia was going to hold back licensing their IP for it if Apple's was chosen, but now say they will).....
but there are certainly comparisons to some of IDCC's proposals in the WGs....that may have had some technical superiorities....but were not chosen because alternatives offered "less" royalties or could impact license negotiations....
