On a different subject. The IEEE 802.14a working group just today put out a ballot to its members to vote on whether or not to shut down the HiPHY working group. The working group had originally been coordinating their effort (they thought) with CableLabs for the the DOCSIS 1.2 project. A few weeks ago, the working group received a letter from David Fellows, Chairman of the DOCSIS Certification Board stating that DOCSIS wasn't interested in the IEEE 802.14a HiPHY work anymore and they [DOCSIS] would go their own way in specifying what they want. It'll take about five to six weeks for the ballot period to finish before the results are known. What this means is that CableLabs is going their own direction and time schedule now for upstream physical layer enhancements for DOCSIS. It is not clear at all at this time how this effects the original selection of S-CDMA for DOCSIS 1.2 or IEEE 802.14a. I gather from what I've heard via IEEE 802.14a, that CableLabs will be pursuing some of the advanced TDMA enhancements that were brought to the table by Broadcom. CableLabs also suggested that they will be looking at other advanced modulation techniques. Mark
