  • then came cisco and the rest is history a history friendly model of the local Area Networking industry
    Journal of Evolutionary Economics, 2015
    Co-Authors: Roberto Fontana, Lorenzo Zirulia
    Abstract:

    We study the role that switching costs, compatibility, and mergers and acquisitions play in influencing the evolution of a multi-market industry. By looking at the case of the Local Area Networking industry, we propose a ‘history friendly model’ to replicate its evolution during the 1990s. Our model explains how a firm can start from a dominant position in one of the existing markets and exploit switching costs and compatibility to enter a new market. Mergers and acquisitions also play an important role as the new market is pioneered by a start-up, which is soon acquired by the dominant incumbent. As a result of the acquisition, the acquiring firm becomes the leader also in the new market.

As a result of the acquisition, the acquiring firm becomes leader also in the new market.

  • 4 times 12 5 gb s wdm optical wireless communication system for indoor applications
    Journal of Lightwave Technology, 2011
    Co-Authors: Ke Wang, Ampalavanapillai Nirmalathas, Christina Lim, Efstratios Skafidas
    Abstract:

    A novel high-speed optical wireless communication system incorporating wavelength division multiplexing technology for indoor personal Area Networking applications is proposed in this paper. Even with the simplest single wide field-of-view (45°) nonimaging receiver, bit rate as high as 4 × 12.5 Gb/s has been successfully demonstrated by experiments. It is shown that error-free reception (bit error rate <; 10-9) can be achieved over the entire beam footprint of about 1 m, so limited mobility can be provided to subscribers. In addition, a new localization system based on this optical wireless communication system has also been proposed and verified by experiments. When these two systems are incorporated together, high-speed optical wireless communication with mobility feature can be provided to users over the entire room.

  • high speed optical wireless communication system for indoor applications
    IEEE Photonics Technology Letters, 2011
    Co-Authors: Ke Wang, Ampalavanapillai Nirmalathas, Christina Lim, Efstratios Skafidas
    Abstract:

    A novel high-speed optical wireless communication system for indoor personal Area Networking applications is proposed and studied. A proof-of-concept experiment at 12.5-Gb/s wireless transmission has been successfully demonstrated with limited mobility. When integrated with a WiFi-based localization system, high-speed optical wireless communication with a mobility feature can be achieved over the entire room. The performance trade-offs between the maximum beam footprint and overall bit rate have also been studied and quantified experimentally and the results show that error-free (BER<;10-9) reception can always be achieved for a wide range of bit rates from 1 to 12.5 Gb/s.

  • Upstream Access and Local Area Networking in Passive Optical Networks Using Self-Seeded Reflective Semiconductor Optical Amplifier
    IEEE Photonics Technology Letters, 2007
    Co-Authors: Nishaanthan Nadarajah, Ampalavanapillai Nirmalathas
    Abstract:

    A scheme for upstream access and local Area Networking in passive optical networks (PONs) using a single self-seeded reflective semiconductor optical amplifier (RSOA) placed in customer premises is proposed and experimentally demonstrated. The self-seeding of the RSOA is performed with the use of fiber Bragg gratings placed at the customer premises to obtain two separate wavelength channels for the transmission of upstream access traffic and local Area network traffic. The experimental results show that this scheme is capable of supporting high bandwidth data transmission in a PON.

  • Sponsors, Communities, and Standards: Ethernet vs. Token Ring in the Local Area Networking Business
    Industry and Innovation, 2003
    Co-Authors: Urs Von Burg, Martin Kenney
    Abstract:

    The discipline of economics has treated technological standards creation as an outcome of network externalities and decisions on the demand side. They pay little attention to the supply side, where firms make strategic choices as to which standard to support. These choices can ignite a contest between adherents to the different proposed standards. This case study examines the contest between the Ethernet and Token Ring standards for local Area Networking. IBM sponsored Token Ring, but then made it difficult for other firms to be successful in supplying components. In contrast, Ethernet's sponsors, DEC, Intel, and Xerox, structured the marketplace in such a way as to encourage supporters. The resulting Ethernet community was able to lower costs and improve the technology so dramatically that the Token Ring standard, which had initially been technically superior, was overwhelmed. We find that the critical difference in explaining the success of Ethernet was the nature and strategy of the standard's sponsors...

  • venture capital and the birth of the local Area Networking industry
    Research Policy, 2000
    Co-Authors: Urs Von Burg, Martin Kenney
    Abstract:

    Abstract Venture capital has played an important role in funding the development of a number of US high-technology industries. Economists and business scholars utilizing models based in traditional economics have studied venture capital from the perspective of investment decision-making. These models provide significant insights, and yet they do not explain the actual operation of venture capital. This case study of the creation of LAN industry utilizes a synthesis of the dominant design and social constructionist perspectives to create a more nuanced explanation of how the practice of venture capitalists operates to create firms and industries.
