OHG, E buries hatchet and paired and unpaired frequency bands, brought to you by Mme Li Mofang (I wonder if she really supports Wu Jichuan or Zhu, and who butters her bread) Ericsson Buries Hatchet With CDMA Group By Jeremy Scott-Joynt 15 June 1999 Ericsson AB has completed its rapprochement with the cdmaOne community by joining the CDMA Development Group at the organisation's world congress in Hong Kong. The move buries the final hatchet in the long-running war of words, and worse, over third-generation cellular standardisation. The CDG has sometimes been perceived as boosting cdmaOne and its potential 3G offshoot, cdma2000 by knocking the competition, which has not always assisted the younger standard's efforts to build a name for itself. Ericsson's accession to the group, alongside other multi-standard vendors such as Motorola, may encourage more co-operation between the CDG and other industry bodies. The announcement rounds out other recent developments which have brought the warring 3G camps closer together. It follows a proposal emanating from the Operators' Harmonization Group of over 30 operators and 12 vendors including Ericsson earlier this month, which held out the prospect of solving the problem of competing 3G standards. The OHG proposal envisages handsets with a dual chip rate, to overcome a key stumbling block long identified by proponents of both cdma2000 and the European and Japanese implementations of W-CDMA. Since all the current 3G candidates are based on code division multiple access technology, the OHG suggests that they could work under a single umbrella standard with three modes, to handle the different modulation methods built into the competing standards. The OHG's proposal came as a welcome relief to the International Telecom Union, which has long made clear its preference for a single umbrella standard for 3G and whose group of radio experts on IMT2000 - the ITU's name for 3G services - met in Beijing last week. The experts' group - dubbed Task Group 8/1 - endorsed the OHG plans, and encouraged them to move on to other contentious aspects of 3G harmonization such as the unpaired time division duplex-based bands which form part of the European W-CDMA 3G standard. "I hope that the success of the OHG in harmonizing the Frequency Division Duplex (FDD) aspects of the CDMA proposals submitted to the ITU - those using paired frequency bands - will be followed with a similar rationalization of the TDD proposals," said Li Mofang, Chief Engineer of China Telecom Mobile Bureau and chair of the OHG. China Telecom is using a single time-divided band as the core of its implementation of 3G CDMA technology. The rush to rapprochement began in March, when the two most vocal combatants in the standards wars made peace. Ericsson and QualComm Inc., which claims IPR over much of the technology underlying cdmaOne, had been at daggers drawn for over two years. Both sides had claimed that the other infringed its intellectual property with respect to different implementations of 3G technology. But in March they settled their differences with an agreement to share technology. The deal gave Ericsson, which already has a strong position in GSM and IS-136, an entree into the only 2G mobile standard it did not support. QualComm, meanwhile, benefited both from getting Ericsson to take over its loss-making infrastructure unit, and from securing a promising stream of future IPR income. © EMAP Media 1999
