• Verizon and AT&T earn substantial scarcity rents from holding nearly all of the original low-frequency Cellular licenses, which gives them operational and quality advantages reflected in their prices and profits. • The 700 MHz spectrum has high " foreclosure value " to Verizon and AT&T, separate from the true " economic value " of building and operating a network. Market entry by new 700 MHz ...

The most important issues in auction design are the traditional concerns of competition policy–preventing collusive, predatory, and entry-deterring behaviour. Ascending and uniform-price auctions are particularly vulnerable to these problems, and the Anglo-Dutch auction–a hybrid of the sealed-bid and ascending auctions–may often perform better. Effective anti-trust policy is also critical. Howe...

In cognitive radio networks (CRNs), spectrum trading is an efficient way for secondary users (SUs) to achieve dynamic spectrum access and to bring economic benefits for the primary users (PUs). Existing methods requires full payment from SU, which blocked many potential “buyers”, and thus limited the PU’s expected income. To better improve PUs’ revenue from spectrum trading in a CRN, we introdu...

We present a bidder aid tool that allows bidders to more effectively participate in combinatorial FCC spectrum auctions by enabling concise expression of preferences. In addition to logical relationships between items, bidders may express spectrum-specific preferences such as those related to minimum population coverage, bandwidth, and budget. The tool can be used to simultaneously generate and...

Mobile communication plays an important role in the future of communication systems. To meet personalized and intelligent requirements, mobile communication has evolved from single wireless cellular network to heterogeneous mobile communication network, including wireless cellular network, wireless local network, and wireless personal network. In the heterogeneous communication system, to entir...

In this article, we investigate the multichannel cooperative spectrum sharing in hybrid satellite-terrestrial Internet of Things (IoT) networks with auction mechanism, which is designed to reduce operational expenditure satellite-based IoT (S-IoT) network while alleviating scarcity issues terrestrial-based (T-IoT) network. The cluster heads selected T-IoT assist primary satellite users transmis...
