Hmm, why cannot these GSM operators do what Viterbi did, "set aside" 1/3 of the capacity for data and then claim it doesn't take any voice capacity, as it already was taken??? Well, Viterbi did not do that, he is just smart, not fundamentally nor intellectually dishonest. Ilmarinen Interseting thing that TDMA (like in US-TDMA or GSM-TDMA??) has some "inherent" capacity advantage over (TDMA-)GSM?? I thought US-TDMa was just to narrowband to be practically usable?? Great that there are great journalists at wireless week who kind of BLAST out these smart things.. "Lucent last year announced plans to integrate smart antennas and a proprietary technology known as Bell Labs Layered Space-Time, or BLAST, in its 3G-ready Flexent OneBTS base station." Well, ok.. "A new CDMA voice vocoder, known as a selectable mode vocoder, could save operators an additional 50% to 60% in capacity" Interesting concept, to use CDMA in voice coding, must be something really orthogonal??? Maybe something invented for Mquerice and his code division clicking cockroaches, without regular human vocal tracts?? Hmm..strange physics.. "Still, as Nokia's Lappalainen pointed out, the methods available to increase capacity are limited by basic RF physics" That is, is it common to have drop out, never understood anything, engineers becoming journalists at wireless week?? (nothing personal, and journalists also have a task in life, just like clicking cockroaches, some even compete with the best of standup comedians)

Anyway, welcome to the thread... great link!! Where is page 53 <33% more voice capacity than TDMA (see figure on page 53)> Most sentences actually have some basic information in them, but it takes some real knowledge of telecommunication and journalistic, telecomm politics to recognize it, IMNHO. Ilmarinen. <"Those are contractual commitments to us with really significant penalties," Clift said. "The more efficiently we use the spectrum, the more we have available for data. It's going to be an aberration as it consumes spectrum, and none of us knows how fast this will happen."> Did the US old AMPS-TDMA license auctions have some clause on how many voice calls per bandwidth, similar to radiolinks,etc, had to be reached?? Lost some of those aspects of that tragic 30kHz time, although it kept AMPS alive until even some few years into the future for USA. (US-AMPS and US-TDMA are based on 30khz channels, and that is were they still are)
