SDR Benefits

• Increased compatibility between dissimilar standards

• Eases technology insertion and generational changes– Allows incremental deployment and upgrade

• Hardware and software can evolve separately– Potentially enables third party HW/SW

• May reduce number of waveforms (and if it doesn’t, it will make them easier to cope with)

• Shorter time to market; fewer hardware platforms in inventory

• Significantly reduces impact of software bugs

Cost of Software “Bug” Fixes – A Real Example• Examples of recent recalls of one manufacturer’s commercial wireless

phones:– February 2001 - Network operator 1: 420,000 phones recalled

(software problem)– May 2001 - Network operator 2: 126,000 phones recalled (software

problem)– July 2001 - Network operator 2: 560,000 phones (design flaw)

• Cost estimate of handset recalls - an example: – Manufacturer’s estimate for cost of recall: $95 M– Independent analyst’s estimate of cost of recall: $160 M

• Cost per terminal of the recall: $115 per terminal

Historical Perspective• 50 years ago wireless systems were entirely hard wired analog components

comprising:

– Ant - Antenna– RFFE - Radio Frequency Front End– (A/D) - Analog / Digital Converter– HSSP - High Speed Signal Processing– LSSP - Low Speed Signal Processing– PS - Protocol Stack– LC - Local Control– HI - Human Interface

• As digital technology has matured, analog discrete components have been replaced first with digital discretes and then with integrated circuits (IC’s) and software

The Open Systems Challenge• Open systems are based on published subsystem and component interfaces

allowing for– Maximum innovation within subsystems and components– Maximum ability to integrate subsystems and components from

optimal sources• Open Systems are the best mechanism to achieve the full social benefits of

SDR• Some industry participants oppose Open Systems

– Seek to retain perceived advantage– There really is no advantage

• Direct regulation of subsystem and component interfaces is – Limited by regulatory charters– Efforts to extend charters have in the past proven to be counter

productive• Regulators should

– Recognize limits of their charters– Use their influence to strongly encourage Open Systems

approaches

Remaining challenges• Regulatory environment

– Universal regulatory environment to promote global circulation of handsets

• Antennas– Efficient, broadband, small

• AD Converters– Faster, cheaper, more power efficient

• Download security– Critical element

• Batteries/power usage– Size and weight are important

What is the SDR Forum’s role?

• A venue to discuss common problems and to promote industry standards without raising issues of collusion

• Regulators’ resource for industry opinion to facilitate creation of rules to ease global circulation

• Create concepts and influence standards for implementation

• Industry water cooler or chat room-- it’s a place to learn about the state of the art

Summary• SDR technology is beyond the education and initiation

phase.

• The SDR Forum is addressing the real needs of SDR development as it looks towards implementation and application of SDRs in a variety of marketplaces.

• The SRD Forum is on track with an active technical specification and standards development program.

• The SDR Forum continues an active program to promote public policy decisions to facilitate SDR adoption and deployment.

• The SDR Forum is actively cultivating liaisons and interfaces with relevant external organizations.
