Why Has the Vision not Flown?

devices have not displaced other carried items

lack of clear vertical market focus

low-performance CPUs, small memories, poor battery life

inadequate input such as handwriting recognition

disappointing ease-of-use factors

inadequate display and keyboard sizes

lack of seamless and ubiquitous communications

cost/value!

Digital-ARM PartnershipDigital-ARM Partnership

DS has negotiated an architecture license from ARM Ltd.• unique position (others are manufacturing licensees only)

DS will develop and manufacture a series of standard products (SPs) and application specific SPs (ASSPs) based on the StrongARM core technology

• Standard Products are general purpose devices

• ASSPs are targeted at specific markets and applications

DS will develop a family of ARM compliant cores (the StrongARM family) which will be made available to ARM Ltd. for sub-license to their manufacturing licensees

• cores are enabling technology for ASSPs and CSSPs (customer specific SPs), from other ARM licensees

Communications Infrastructure Trends Next-generation wide-area technology in the U.S. evolving

towards PCS in spite of technological confusion;

GSM will continue to dominate in Europe and other overseas markets;

CDPD, packet radio (RAM Mobile, ARDIS), one- and two-way paging, will continue to find niche markets;

emerging: wireless cable, ESMR, satellite, television

wireless LANs will continue to grow; residential?

Market Projections

The installed base of wireless data subscribers in the U.S. is expected to grow from 500,000 in 1994 to nearly 10M in 2000.

Driving factors:

move towards the untethered, mobile workforce;

gradual build-out of the wireless infrastructure;

deregulation and spectrum auctions;

emergence of end-user client-server business applications and middleware.
