Hi land_crusin, I too enjoy intellegent dialogue. Here are my thoughts. 1)we both know sectorization does not work well in the cities I would not rush to "not work well" conclusion. Besides as I said, CDMA is still a relatively new technology, the fact that there are so many "proposals" and "debates" in standard body tells you how much rooms it can still grow. The bottom line is it is interference limited so how to deal with that interference is the key. Just look at how many CR's being filed from either 3gpp or 3gpp2 will tell you it's far from perfection. 2)About the recent 1X trials, from what I gather from a very reliable source, this was achieved purely by allocating 3X the normal # of walsh codes to that cell. Nope, better check your source again. Actually the capacity is not because of number of walsh codes(128 in 1x for 1.25Mhz), walsh code only serves the mean to seperate users. the key point is Eb/Nt , like I said before, CDMA in its spirit is a game of power. Codecs do the show and powers win the game. You can only use that many codes under the power restriction. 3) but the problem IMO is that is is still built on top of voice based networks Yes and no, it minimizes the cost by doing the overlay on top of the current cell infrastructure. But the traffic itself going directly to the internet. All you need to do is add in new cards and a router and there you go. HDR using different frame size for data. The size is the trade of between data characterristic and BER. You can't choose too big a frame size because radio environment is not as reliable as wired connection. Do you work in the industry? Simply put, yes:-) BTW, I don't really feel comfortable to talk in length about Qcom technology on MCOM board, esp. that I don't have in depth knowledge in MCOM technology. So I suggest we move HDR discussion to Qcom board in the future to keep the discussion on topic. -Regards
