Tokyo firm goes beyond UMTS
May 8, 2003
Communications Research Laboratory, a Tokyo-based firm, says it will
invest £1.05million in a new Singapore facility dedicated to developing
4G mobile technology.
CRL is a lab with links to the Japanese government that researches communications
and photonics (the integration of functions typically handled by optical
fibre into silicon chips), covering areas from ultrawideband radio to
satellites.
CRL and its Singapore partners will also work on cellular technology
that goes beyond the current 3G and into 4G.
While this 4G mobile network promises video conferencing and high-speed
Internet access, the most important change is that its next-generation
handsets can adjust to suit a person's needs.
"A user could be downloading a movie clip at lower data rates using the
cellular network, but when he moves into a wireless hot spot, the download
automatically kicks into higher gear -- all this switching is transparent,"
said Masayuki Fujise, director of CRL's Wireless Communications Laboratory.
The development of software defined radio (SDR) applications is the key,
he said.
Many see software radios -- which can mimic any kind of wireless standard
using only programs stored in memory -- as the answer to the problem of
incompatible wireless networks.
"Right now, the software inside a mobile phone is configured to access
only the cellular network. But with SDR, the software algorithm can be
tweaked to allow interoperability between different wireless networks,"
Fujise said.
