“DoCoMo (meaning ‘anywhere’ in Japanese) is a NTT subsidiary and Japan’s biggest mobile service
provider, with over 31 million subscriber as of June 2000. In February 1999, NTT DoCoMo launched its
i-mode service. Within one year, it had over four million subscribers, and within another six months it
went up to eight million and had overtaken other Japanese Internet service providers (ISPs) that provide
service to the desktop. DoCoMo’s i-mode is the only network in the world that now allows subscribers
continuous access to the Internet via mobile telephone. The service lets uses send and receive e-mail,
exchange photographs, do online shopping and banking, obtain financial information, d.................
NTT DoCoMo has looked at ways to penetrate the U.S. market. Some observers are skeptical about
whether i-mode would succeed elsewhere. They note that Japan may be a unique market, with unique
characteristics that, may not exist elsewhere, such as a huge audience interested I using the Internet,
culturally specific content, and a huge commuting population. According to one analyst, successful
mobile applications are highly specific to cultures and national demographics. What flies in Japan won’t
necessarily fly in the States or Europe.
Questions:
1. How does this case demonstrate the importance of data transmission rates in business? Does it
imply that people in Japan are willing to accept lower data rates than people in the U.S.?
2. Some people say that the Internet fosters globalization by providing world wide access to the
Web. Discuss arguments for and against this statement.

Caselet 2
Transmeta Corporation was founded in 1995 to build a new type of computer chip directed at mobile
applications that rely on battery power to run laptop computers and other portable devices. The company
said nothing about its product until an unveiling on January 19, 200. By October 2000, NEC, Sony, and
Fujitsu had all launched notebook computers based on its Crusoe chip. Sony said it will use the processor
in its new Vaio Picture Book CIVN notebook, and Transmeta claimed that Crusoe should nearly double
the battery life of the new model. Transmeta’s Crusoe product ..........................
notebook computer also consumes a lot of power. He thought the battery life advantage in this market
would be no more than 30% to 40%. After IBM decided not to go ahead with the Crusoe for its new
product, a spokes-woman said, “The IBM 480 notebook has a battery life of 4.5 hours and it was hoped
that Crusoe would extend this to eight hours. However, Crusoe only managed 5.5 hours in IBM’s
benchmarking test.” A Gartner Group consultant said,” The main issue is performance. The chip uses
emulation or ‘code morphing’ and therefore does not give the same performance as you get with
Intel…..the reason IBM moved away from the chip is that either there was not enough power or there was
not enough performance.” There was no guarantee that the Crusoe chip or Transmeta would succeed,
especially since Intel and other companies were developing chips for the same market.
Questions:
1. Why might portable computing and desktop computing call for different types of microprocessors?
2. Review the performance variables. In which areas did the Transmeta chip try to excel?
1. DNS is a distributed database system that operates on the basis of a hierarchy of names. Explain
the statement & also explain how DNS servers work.
2. Explain the workings of GSM, UWC, CdmaOne & PDC technologies of digital cellular.
