Spectrum fragmentation: Causes, measures and applications

Spectrum fragmentation, a concept that describes the degree of split for a given portion of spectrum, is a newly emerging issue which can affect productivity and technical efficiency in spectrum use as the telecommunication service paradigm evolves from voice oriented to data oriented services.

This paper proposes ten indices, compares them and calculates their values for Korea and Japan. The values of all indices range between zero and one, so one can use them for international comparison of spectrum fragmentation. Out of ten indices, three are Theil indices, comparing the discrepancies between spectrum and subscriber distributions. In addition, this paper discusses policy alternatives to lessen the spectrum fragmentation problem.

ARRIS: Every Carrier Will Become a Wireless Provider, So We Bought Ruckus Wireless

ARRIS will acquire Ruckus Wireless and ICX Switch business from Broadcom subsidiary Brocade Communication System for $800 million in cash, as well as unvested employee stock awards. The deal is contingent upon Broadcom successfully completing the acquisition of Brocade Communications, which owns both ARRIS’ acquisition targets. Acquiring Ruckus and ICX Switch will further expand ARRIS’s presence in wired and wireless networking technology and markets beyond the home to encompass the education, public venue, enterprise, hospitality and MDU market segments. Off the back of acquiring Ruckus and the ICX Switch business line, management intends to create a business unit dedicated to marketing innovative wireless networking and wired switching technology that can meet the needs of various industry sector verticals. ARRIS previously acquired Motorola and Pace. “We’ve set an aggressive growth strategy for ARRIS that includes expanding our technology breadth and depth with a focus on wireless broadband,” said CEO Bruce McClelland.
