I think the argument about 1X being 3G or not is pointless. 3G is about content. 1X brings in voice capacity gains, and some data speed. Data speed of 1X is certainly good enough for the first wave of 3G content. By the time there is a need for apps that require faster data speeds such as video streaming, and by the time there are phones that have the processing power to handle those apps, networks will support faster speeds due to the natural evolution of 1X. If you had the speeds for streaming video in the network right now, phones would not be able to process it and keep up with the data speed. Processors in today's phones are not powerful enough to run data and play a video at the same time. Evolution is a good thing.

re: ITU IMT-2000 3G Guidelines for Data Transmission. << the original spec staked out a minimum of 384Kbs rising to 2Mbs as the systems evolved >> Actually, Rob, the minimum requisite (peak) data transmission speed to legitimately meet ITU IMT-2000 3G guidelines is 144 kbps in a "high mobility" (rural outdoors mobile) macro-cell environment in a vehicle traveling more than 120 kilometers per hour (75 MPH). The 384kbps requirement for full mobility (also referred to as pedestrian speed) is for 3G users who are travelling/moving less than 120 kilometers per hour in outdoor urban micro-cell environments. The 2Mbps low mobility (less than 10 kilometers per hour) guideline is for stationary indoor and short range outdoor pico-cell environments. One point that journalists tend to exagerate when criticizing dumbed down 3G is that the ITU did not specify average data throuhput. They were talking "peak". In the end, the carrier will decide what is "3G" and what isn't, so Verizon and PCS call 1xRTT Release 0 3G, while SKT calls it 2.5G and SKT reserves the appellation "3G" for 1xEV-DO & 3GSM WCDMA. Jørgen Sundgot comments on this: >> cdma2000 Claimed To Lead 3G Race Jørgen Sundgot infoSync 11.06.02 17:52 GMT The CDMA Development Group says CDMA2000 technology is leading 3G with over 98 percent market share - but there's heated debate as to what should be counted as 3G and not. The CDMA Development Group (CDG) today announced that there are more than 10 million CDMA2000 subscribers worldwide, accounting for more than 98 percent of the total number of 3G users. However, despite the impressive number of total users, the vast majority of these only have access to CDMA2000 1xRTT networks - a technology which is subject to heated debate concerning whether it should be counted as 3G or not. According to numbers provided by the CDG, CDMA2000 continues to grow at a phenomenal rate, now adding nearly 1.5 million subscribers per month. Numbers were however not disclosed for what percentage of subscribers utilize CDMA2000 1xRTT networks as opposed to CDMA2000 1xEV-DO networks - the latter of which without doubt qualifies as a 3G network. 1xRTT networks are capable of transmitting data at speeds of up to 144 Kbps to stationary terminals, but are not capable of doing so to mobile terminals, thus falling outside the IMT-2000 specification for 3G networks. In real life, speeds achieved from CDMA2000 1xRTT networks typically run as high as 40-60 Kbps, leading to further withering of the ground the CDG's claim rests on, and proving that the so-called 3G technology in reality competes with GPRS in terms of real life transfer speeds - which the industry has since long agreed to is a 2.5G technology. Still, the CDG continues to pitch CDMA2000 1xRTT as 3G technology as Perry LaForge, executive director of the CDG stated that "The CDMA community has once again shown extraordinary leadership in 3G wireless communications." Additionally, industry analyst and editor-in-chief of Forbes/Andrew Seybold's Wireless Outlook, Andy Seybold, follows up; "With 3G CDMA technology, operators are increasing revenue opportunities by providing subscribers with leading-edge multimedia applications, while consumers benefit from the wide variety of applications and devices available today. The CDMA industry's landmark achievement of reaching 10 million subscribers further validates the fact that CDMA is leading 3G." Currently, there are 15 operators in the Americas, Asia and Europe offering 3G services through CDMA2000 according to the CDG. Of these, only SK Telecom and KT Freetel (both of Korea) have operational CDMA2000 1xEV-DO networks - leaving the percentage of networks that undoubtedly can be called 3G networks at 13%. << Best, - Eric -
