Third generation cellphones might not be able to receive lengthy music or
movie clips, according to Keiichi Enoki of NTT DoCoMo, the Japanese pioneer of
mobile Internet services. DoCoMo tested transmission over a prototype 3G
network, and concluded that only video clips of 10 to 15 seconds will be viable,
because they hog so much expensive bandwidth. Japan’s 3G network is due for
launch next year. Enoki believes such networks will find it hard to justify the
billions they have spent on 3G licences, and some observers now think digital
radio will be better at sending full-length video clips to handsets.
