More on the same with q IPR mentioned: FYI_ Korean market contiues to drop: South Korea Seoul Composite 280.00 -8.21 -2.85% Telia Tests W-CDMA to Find a Smooth Ride From GSM By Jeremy Scott-Joynt 16-JUN-98 Ericsson is to start tests on its wideband CDMA platform for third generation mobiles with Telia AB, Sweden's state-owned telecoms operator. ÿÿÿÿÿÿ The trials will start in the autumn, and are intended to allow both Ericsson and Telia - as a carrier planning eventually to introduce 3G W-CDMA services - to evaluate the capacities of the system. ÿÿÿÿÿÿ "We've mostly worked with time division multiple access systems (like GSM), and we are keen to see how code division multiple access works in practice," said Lorentz Engstr”m, Telia Mobile's head of strategic business development. "We need to know how to work out details such as cell planning and so on." ÿÿÿÿÿÿ The main focus will be experimenting with the air interface's multimedia capabilities, recognized by both vendors and carriers as the key selling point of 3G, when it comes onstream in Europe around the year 2002. ÿÿÿÿÿÿ But according to Engstr”m, it's also important to begin charting the upgrade path from GSM to W-CDMA, or the Universal Mobile Telecoms System (UMTS), as Europe has dubbed 3G. ÿÿÿÿÿÿ "In order to evaluate the system properly, we have to see how to grow out of the existing GSM system to the new one," he said. "We will be running W-CDMA on our GSM network as a test." ÿÿÿÿÿÿ Ericsson has already announced tests in Germany of W-CDMA, in collaboration with GSM900 operators Mannesmann Mobilfunk and T-Mobil, and has been working closely both with Nokia and with NTT DoCoMo, the other two W-CDMA pioneers, on tests in Japan for the last few months. ÿÿÿÿÿÿ Since the specification is by no means finalized, the trials will give the companies an opportunity to shake down the system in a real-world situation, as well as reassuring the operator community about the upgrade path. ÿÿÿÿÿÿ But another consideration is that intellectual property problems with CDMAOne originator QualComm continue to dog its development, after the US vendor announced earlier this month that its IPR - on which it claimed W-CDMA depended - would not be available in the absence of compatibility with its narrowband CDMAOne, or IS-95, system. ÿÿÿÿÿÿ Soon after QualComm's announcement, a DoCoMo official said the companies were talking about finding ways to get around any blockage imposed by QualComm. The trials may well act as a testbed for finding a solution to that problem.
