Hi All Usually I am just a listener here but the past week (or two) mail activity is not what I call technical discussion. start with the last: in Japan, KDDI corp utilize cdma2000 1X-RTT network, which some will call 3G but no one will compare it to WCDMA (UMTS) except of course if this one is a news reporter. second EDGE is 3G like cdma2000 1X-RTT is 3G, which both if you don't mind me saying are NOT 3G. 3rd Generation cellular networks provide up to 2Mbps (cdma2000 3X, UMTS), EDGE can NOT do that nor can 1X-RTT. Why don't you add this to the draft : "EDGE is a 2.75G technology" ? cheers dor -----Original Message----- From: Farid Khafizov [mailto:[email protected]] Sent: Wednesday, September 04, 2002 9:12 PM To: '[email protected]' Cc: Jayshree Bharatia Subject: RE: [pilc] Comments on draft-ietf-pilc-2.5g3g-10.txt Hi all, I agree with Jayshree's comments. See, for example, today's article from Reuters http://biz.yahoo.com/rf/020904/telecoms_qualcomm_1.html <http://biz.yahoo.com/rf/020904/telecoms_qualcomm_1.html> supporting the view that no geographical regions should be mentioned in the text: "CDMA2000 is leading WCDMA by a substantial margin in Japan, which is often described as the main battlefield between the two technologies. DoCoMo's 3G service had attracted 127,400 users as of the end of July, less than one tenth of 1.64 million subscribers for rival KDDI Corp (Tokyo:9433.T - News), which offers a CDMA2000-based 3G service."

In the Introduction section, it is mentioned that "Radio technology for both Wideband CDMA (W-CDMA) (Europe, Japan) and cdma2000 (US, South Korea) is based on code division multiple access allowing for higher data rates and more efficient spectrum utilization than 2G systems" In this paragraph, W-CDMA and CDMA technologies are associated with different countries which is misleading since one country can have both W-CDMA and CDMA. Hence, my suggestion is to remove name of countries mentioned in parenthesis. 2. Through out this draft there is a mention of 2.5G which may be just specific to certain wireless technology and not all, e.g. CDMA doesn't have 2.5G. Instead "pre-3G" term is more appropriate. Thanks, Jayshree
