I did not have malfunctioning, forgetting handsets in mind, just a handset diving through deep and multipath fading, additionally far from the basestation, badly needing that fast power control, but the downlink with that control is just as faded. The MIPS amount needed to track this for an otherwise slow voice channel is tremendous, and data decisions are few (8kbps vs 1 or 4MHz chip rate, wavelength of carrier and speed of car) If the decisions go bad there is no way one can track the fadings, level has to be increased, affects all other handsets,etc.. GSM, on the ohter hand, has a new training signal in every timeslot, every timelost is a totally new independent "universe". Adjusting the position of the time slot is non-critical, one cannot move so fast towards or away from a basestation that it would cause severe overlapping. The reason for GPRS not going for using 8 nor 7 out of 8 timeslots for receiving, but 6, is that the transmit timeslot should not overlap with the receive timeslots, takes time to turn off the transmitter and let things get silent, ring out in the receive path. (DC levels, AGCs,etc) The basestation can have much more expensive, bulkier, power hungry filters to separate tx and rx bands. Ilmarinen

NOK's Jorma. \|No sequential decline in mkt share. 40% is a tough target. Slower NOK growth in 1st half of 2002. Just can't predict profits in 2002 due to uncertainties of 3G adoption pattern. Sees 3G revenues possibly kicking in by Summer 2002. Much hemming and hawing at questions. Refused to give specifics about current field testing on GPRS. Concl: Jorma says all is OK because GPRS and 3G scheduled to kick in in Q4 2001 and then in mid 2002. He is hanging his hope on getting this new technology out on a timely basis and on the market really likeing it. Under huge pressure to deliver something tangible. Opinion: GPRS will continue to be delayed and will be a dud in many markets when it arrives. Shear momentum will force many operators to buy GPRS phones if they work at all. There will be an accumulation of bitterness among operators about failure to provide new killer products.
