Telenor can't object Oniway closure January 6, 2003 Telenor cannot oppose the closure of its partly owned Portuguese 3G license holder Oniway said Santander Central Hispano, a bank of Spain. Electricidade de Portugal, which has a 68% stake in Oniway, decided in late last year to close down the startup 3G unit. Telenor (20%) and minority shareholder Iberdrola (8%) said they would oppose the decision, fearing it may require an injection in cash. Oniway's 3G assets would be sold to the three other operators, TMN, Telecel and Optimus. In addition Telecel agreed to purchase all of Oniway's shares, which gives it the right to use the operator's tax credits. But Telecel may face difficulties in fulfilling its promise. "Thus, this part of the transaction might be at risk and ultimately penalise OniWay's shareholder value," SCH said. Investments in Oniway had reached €484 million but repeated delays in the launch of 3G has forced EDP's decision to pull the plug on Oniway. In October 2002, OniWay carried out a live demonstration of its UMTS network in Portugal. The trial consisted of voice calls and a variety of visual and audio communications such as video conference, video and audio streaming and web browsing. 3gnewsroom.com

Ben, re "fundamental to the 3GPP2 standard for 1xevdo are specifications for the integration of 1xrtt voice channel(s) for voice+data services." Consider the following: (1) Although a data link with sufficient throughput could support voice, I don't think we are talking about Voice-Over-IP here. (2) The word "voice" is NOT USED EVEN ONCE in the 1xEV-DO specification. See 3GPP2 C.S0024 "cdma2000 High Rate Packet Data Air Interface Specification" (Sep 12, 2000). 3gpp2.org Interestingly,the 1xEV-DO acronym is not defined in the spec. (3) The word "voice" is NOT USED EVEN ONCE on QCOM's FAQ About 1xEV-DO. The link Kayaker provided is qualcomm.com. As Kayaker quoted, QCOM interprets "DO" <=> "Data Optimized". (4) The MSM5500 is QCOM's first ASIC to support both 1x voice and 1xEV-DO data. A PR for this chip says: "The MSM5500 and CSM5500 solutions support the industry-adopted CDMA2000 1X Evolution Data-Optimized (1xEV-DO) standard, designed for high-speed wireless data, which uses a spectrally efficient 1.25 Megahertz (MHz) channel to provide a peak data rate of 2.4 Megabits per second (Mbps) on the forward link." and "The MSM5500 solution supports hybrid mode operation between CDMA2000 1X and CDMA2000 1xEV-DO systems ... " re "hybrid mode". This implies side-by-side support (silicon, firmware, software, etc.) It is hardly an indication that DO supports voice+data. QCOM is consist and again says "DO" <=> "Data Optimized". (5) AFAIK with DO, voice plus data requires an rf overlay. In other words, any given rf channel does not do both 1x and 1xEV-DO .. at the same time. A minimum of 2.5 MHz downlink and 2.5 MHz uplink bandwidth is required to support both voice and data in a geographical area. That sure doesn't sound like DO supports both either. (If you want a link to support this point, I shall try to find one.) The BTS is mostly unchanged AFAIK .. maybe an added PC card .. and a connection to the data network, of course. The minimum bandwidth requirements would IMHO become 1.25 MHz downlink and 1.25 MHz uplink if cdma2000 1xEV-DV ever becomes a reality. Are you maybe thinking of the 1xEV-DV spec? Or maybe erroneously extending the functional integration within the MSM5500 into other network areas? If neither is true, would you please provide additional support for your statement at the opening of this post? Thanks. Ron :-)
