Business Innovation Strategies to Reduce the Revenue Gap for Wireless Broadband Services

by Jan Markendahl, Östen Mäkitalo, Jan Werding, Bengt G. Mölleryd
"... Abstract: Mobile broadband is increasing rapidly both when it comes to traffic and number of subscriptions. The swift growth of the demand will require substantial capacity expansions. Operators are challenged by the fact that revenues from mobile broadband are limited, just a few per cent of APRU, ..."

Asymmetric–valued Spectrum Auction and Competition in Wireless Broadband Services

by Sang Yeob Jung, Seung Min Yu, Seong-lyun Kim
"... Abstract—We study bidding and pricing competition between two spiteful mobile network operators (MNOs) with considering their existing spectrum holdings. Given asymmetric-valued spec-trum blocks are auctioned off to them via a first-price sealed-bid auction, we investigate the interactions between t ..."

always lowers his service price despite providing double-speed LTE service to users. We also show that the MNO who acquires the high-valued spectrum block, despite charing a higher price, still achieves more market share than the other MNO. We further show that the competition between two MNOs leads

Versatile Low Power Media Access for Wireless Sensor Networks

by Joseph Polastre, Jason Hill, David Culler , 2004
"... We propose B-MAC, a carrier sense media access protocol for wireless sensor networks that provides a flexible interface to obtain ultra low power operation, effective collision avoidance, and high channel utilization. To achieve low power operation, B-MAC employs an adaptive preamble sampling scheme ..."

SEAD: Secure Efficient Distance Vector Routing for Mobile Wireless Ad Hoc Networks

by Yih-Chun Hu, David B. Johnson, Adrian Perrig , 2003
"... An ad hoc network is a collection of wireless computers (nodes), communicating among themselves over possibly multihop paths, without the help of any infrastructure such as base stations or access points. Although many previous ad hoc network routing protocols have been based in part on distance vec ..."
