Introduction: Some General Thoughts on Sources and Methodology
The page below documents the substance of my research, but I thought it might be helpful to start with some reflections on methodology.
In general, my research went from technology, to business/economics, to law, only reaching the specific questions we're interested in after a few weeks of background orientation. I found access to an engineering library to be essential for the first phase, in order to get a general sense of what the building blocks of networks are and what the broad areas of recent innovation have been.
As I began to look at the business and economics, I found B-school cases to provide invaluable general context, though they play a little too fast and loose with the details to be helpful with specifics. Through other work I also happened to have access to some pretty great analyst overviews as well as opportunities to have direct conversations with some of the leading analysts who research the field for institutional investors, and if you can get those they can be pure gold. Reading the annual reports of some of the large actors also proved surprisingly helpful.
Once I had a general sense of the players on the field, I moved onto the specifics of the legal models and dynamics of IP. I suspect that the Carnegie Melon and SEER studies will be touchstones for all our research areas, as they were for me. I also found articles in practitioners' legal periodicals (as distinguished form traditional law reviews) to be helpful. My sense is that these articles provide a useful insider's impressionistic perspective of industry dynamics that can be lacking from traditional law review articles. There was a lot of other secondary academic empirical research, but I honestly haven't find that much beyond the Carnegie Mellon and SEER studies that I found particularly helpful.
Various previously published case studies and news articles about specific companies and transactions provided the examples that filled out the legal section of the overview. I found these to be very helpful, but I also tried to be very cautious about drawing too many conclusions from just a few high profile examples, which I think is an easy trap.
Field Definition
Basic Definition
"The word 'telecommunications,' a twentieth century amalgam of Greek and Latin roots, literally means the art of conveying information 'from a distance.' . . . Today, although precise definitions differ, 'telecommunications' is broadly defined as the transmission of information by means of electromagnetic signals: over copper wires, coaxial cable, fiber-optic strands, or the airwaves." (Neuchterlein & Weiser 2007, at 1-2)
Taxonomy of Telecommunications Industries
Focus Market Segments
- Wireline
- Cable
- Commercial Wireless (Cell Phone)
- Unlicensed Wireless Data (esp. 802.11)
- Internet-Based Communications Platforms
Deprioritized Market Segments
- Satellite MVPD
- Broadcast TV
- Broadcast Radio
- Satellite Radio
- Other Wireless (public safety radios, dispatch radios, maritime communication, cordless phones, etc.)
Excluded From Field Definition
- Pure Content, including:
- Television, or Radio Programmers (Other than Broadcast Networks, which are in a vertically integrated distribution-and-content businesses)
- Online Content Platforms (vs. Communications Platforms) (e.g. Hulu, iTunes, Netflix). We also place user-generated content platforms like YouTube and Wikipedia in this category, although arguably they have a communications dimension.
Overview of the Field
Analysis of the field based on Field Research Methodology, but compacted and rearranged somewhat. I've also provided a reference page providing a Research Methodology Index for Telecommunications which maps specifically from the questions in the research methodology to the narrative below.
(Note that the sections below are abandoned, as I've now moved my work on this summary to an offline document, to be posted to the Google Group shortly.)
- Introduction to Telecommunications Industries
- Value Chain in Telecommunications
- Economics of Intellectual Property in Telecommunications
Case Studies
Possible Ways to Organize Case Studies
Network Components
- Fiber
- Legacy Last Mile/Last 100 Feet (DOCSIS/DSL/MoCa?)
- Wireless Last Mile/Last 100 Feet (3G/4G/802.11)
- Services (Operator Provided Content & Managed Services / Internet "Over-the-Top" Services)
Layers
- Physical Layer
- Network Logical Layer
- Data Link Layers
- IP Layer
- Service/Application/Content Layer
Candidates for Case Studies
CDMA/Qualcomm (Wireless Last Mile ; Logical Layer)
The most oft-told story of aggressive patent use. Lots of supporting material should make this one easy to write.
- David Mock, The Qualcomm Equation: How a Fledgling Telecom Company Forged a New Path to Big Profits and Market, 2005.
- David J. Goodman & Robert A. Myers, 3G Cellular Standards and Patents, 2005 IEEE Wireless Comm. ?, available at http://eeweb.poly.edu/dgoodman/wirelesscom2005.pdf
GSM (Wireless Last Mile ; Logical Layer)
- Rudi Bekkers Bart Verspagen, Jan Smits, Intellectual Property Rights and Standardization: The Case of GSM, 26 Telecom. Pol. 171 (2002).
- Rudi Bekkers et al., Intellectual Property Rights, Strategic Technology Agreements and Market Structure: The Case of GSM (Sept. 2000), at http://www-edocs.unimaas.nl/files/mer00030.pdf

Erbium Doped Fiber Amplifier (EDFA) (Fiber ; Physical Layer)
A good physical layer example, showing a significant role for university research.
- Philippe C. Becker, N. Anders Olsson & Jay R. Simpson, Erbium-Doped Fiber Amplifiers: Fundamentals and Technology, 1999.
Others
- SONET optical standard? - Fiber ; Logical Layer
- Discrete Multitone (part of the the DSL Standard) - Legacy Last Mile ; Logical Layer
- Some discrete component of DOCSIS standard (perhaps security protocols?) - Legacy Last Mile ; Logical Layer
- Some part of 802.11 standard - Wireless Last 100 Feet ; Logical Layer
- Internet Protocol - All Network Components ; Logical Layer (well known story, hugely important, illustrates public sector importance)
- Google Voice vs. New Alcatel-Lucent Voice Product - Service & Application Layer (direct competition between in-network and over-the-top services)
- WebEx Cisco Acquisition - Service & Application Layer (over the top provider gets bought by tradition in-network equipment provider)
- Some open source Internet-based telecom Project? - Service & Application Layer
Interviews
My current intention is to do interviews after I have written the narrative, and share that with interviewees as a first pass to get their reactions. Possible candidates for interviews:
- Tom Eisenmann, HBS
- Terry Huval, Director of Lafayette, LA Utility Systems‘ FTTH project
