Technical Rate of Substitution of Spectrum in Future Mobile Broadband Provisioning

Dense deployment of base stations (BSs) and multi-antenna techniques are considered key enablers for future mobile networks. Meanwhile, spectrum sharing techniques and utilization of higher frequency bands make more bandwidth available. An important question for future system design is which element is more effective than others. In this paper, we introduce the concept of technical rate of substitution (TRS) from microeconomics and study the TRS of spectrum in terms of BS density and antenna number per BS. Numerical results show that TRS becomes higher with increasing user data rate requirement, suggesting that spectrum is the most effective means of provisioning extremely fast mobile broadband.Comment: 5 pages, 5 figures, conferenc

Siting Foreign Law: How Derrida Can Help

Secondary spectrum access to TV white spaces is considered as a promising solution to relieve the spectrum shortage. In Europe, SE43 working group in CEPT is leading the discussion on the technical requirements for exploiting TV white spaces through the recent ECC report 159. Its analytical approach for determining the maximum permissible power for the secondary user, however, overestimates the power level, and leads to significant violation of the interference limit for TV reception. In this letter, we address the problem by proposing a new approach for determining the secondary user transmit power based on the framework established in ECC report 159. Monte Carlo simulation shows that our method keeps the interference lose to the target.QC 20121113QUASA

Alvarado Revisited: A Missing Element in Alaska’s Quest to Provide Impartial Juries for Rural Alaskans

In Alvarado v. State, the Alaska Supreme Court declared that an impartial jury is a cross section of the community and that the community where the events at issue transpired must be represented in the jury. This decision spurred changes to jury selection procedures and the creation of Criminal Rule 18, an effort to ensure defendants from remote villages are judged by a jury representative of these rural areas. The Alaska Court of Appeals recently addressed an issue of first impression regarding the application of Criminal Rule 18. In Joseph v. State, the defendant was convicted of murdering his girlfriend in the tiny Native village of Rampart. His trial was conducted in Fairbanks by a jury selected from an area that does not include Rampart or any other similar Native village. Criminal Rule 18 allowed the defendant a limited time to transfer his trial to Nenana, which more closely resembles the characteristics of Rampart. However, the defendant was never informed of this right. His trial counsel believed trial location was a decision for the attorney and did not see a need to request the change. In a memorandum opinion that creates no binding precedent, the Court of Appeals agreed with this view and held it did not violate the defendant’s due process rights not to be informed of the opportunity to have his case heard at an alternative trial site. This Article challenges that view, arguing it fails to safeguard the spirit and purpose of the constitutional right to an impartial jury. To remote villagers in Bush Alaska whose customs, culture, and ways of life are vastly different than in larger cities within the state, the opportunity to be judged by those sharing similarities is of upmost importance. Consequently, decisions of trial venue, for purposes of Criminal Rule 18, should be knowingly made or waived by the defendant
