Outline1. Technical characteristics of VoIP-modularity
2. Analysis of VoIP economical characteristics, such as indivisible, fungible, cumulative and complementary in respect to internet protocol.
3. Layer model
4. Telecommunication industry toward the info-communication industry knowledge dynamics.
5. Two main models of VoIP application and the criteria for distinguished them.
3
Two main applications •IP network Voice service” providers are Internet Service Providers (ISP), technology applied to the broadband networks; they offer free calls and other bundling services, examples are Iliad/ Free, Talk-to-Talk, Vonage, FastWeb -1999 and 2001 •“VoIP software- service” allows communication PC-to-PC, thus the communication is made thanks to free software downloading, such as Skype, Yahoo voice messenger - 2002 and 2003
Incumbents have applied the technology only for enforcing the backbone- no new offers for consumers (less competitive)
4
Objective • The article shows how the VoIP
technology is transforming the telecommunication industry into the info-communication industry. How these generate knowledge dynamics into the industry as it became IP based and how these changes generate welfare for the consumers.
• Evolutionary approach and knowledge economy
5
1. Technical analysis
• Distinction among packet switching technology and circuit switching (traditional public switched network-PSTN)
• VoIP reduces the cost of communication
VoIP could be considered as a module
modularity- (Baldwin Clark, 1997; Steinmuller, 2005)
6
Economics characteristics of VoIP
VoIP is coming from a “general purpose technology” (Bresnahan, Trajtenberg, 1995; Verspagen, 2007) the internet protocol. For this reason, I assume that it has the same characteristics of knowledge: indivisibility, cumulative, fungible and competitiveness.
(Scotchmer, 2005, Antonelli, 2005)
7
Knowledge dynamics
Technological convergence (telecommunication/internet)
Convergence of Services/applications
(voice+ value added services)
VoIP software
Cumulative and indivisibility
(voice send on the internet network)
Fungible
(more internet based applications are possible
IP network voice providers
Cumulative and indivisibility
(applied to the TCP/IP network)
Competitiveness
(the merger/combination of voice and value added services)

IV Navigation (browsers engines, electronic payment security)
Google, Yahoo
III End-to-end connectivity (email, VoIP) Skype, PayPal (ISP-internet service providers et ASP-service acces providers)
II Network transmission (optical fibre, ADSL, cable, wireless -Wifi, Wimax)
Incumbents and new entrants on the network building
I Equipments and software (transmission equipments, switches)
Alcatel/Lucent, Cisco, Nortel

Some economics evidences
• Explanation into the resource based view (Penrose, 1959)
• Creation of economy of scale and scope (Davies , 1996, Maeda al. 2006)
• Vertical integration of production
11
Info-communication industry vs. old telecommunication industry
• Open innovation system• Low barriers to entry
many innovations• Based on general
purpose technology• Innovation incentive –
new technologies and applications
• Rapid, concurrent, innovation
• Closed innovation system• High barriers to entry• Few innovations• Fragmented Knowledge
based • Medium-powered
incentives• Slow, sequential,
innovation

Conclusions
• The Knowledge dynamics has been a vehicle of welfare for consumers
• Policy implication, VoIP diffusion fosters the widespread of broadband internet connection
