Designing and Implementing Future Aerial Communication Networks
Providing "connectivity from the sky" is the new innovative trend in wireless
communications. High and low altitude platforms, drones, aircrafts and airships
are being considered as the candidates for deploying wireless communications
complementing the terrestrial communication infrastructure. In this article, we
report the detailed account of the design and implementation challenges of an
aerial network consisting of LTE Advanced (LTE-A) base stations. In particular,
we review achievements and innovations harnessed by an aerial network composed
of Helikite platforms. Helikites can be raised in the sky to bring Internet
access during special events and in the aftermath of an emergency. The trial
phase of the system mounting LTE-A technology onboard Helikites to serve users
on the ground showed not only to be very encouraging but that such a system
could offer even a longer lasting solution provided that inefficiency in
powering the radio frequency equipment in the Helikite can be overcome.Comment: IEEE Communications Magazine 201
Willingness to pay for genetic testing for inherited retinal disease
This paper investigates the willingness of adults with inherited retinal disease to undergo and pay for diagnostic genetic testing in three hypothetical scenarios and to explore the factors that influence decision making. Fifty patients were presented with three scenarios whereby genetic testing provided increasing information: confirming the diagnosis and inheritance pattern alone, providing additional information on future visual function, and identifying in addition a new treatment which could stabilise their condition. Willingness to pay (WTP) was elicited using an iterative bidding game. Regression analysis was used to investigate the probability of agreeing to and paying for testing. Qualitative data were also reviewed to provide a comprehensive understanding of WTP and decision making. The majority of participants agreed to undergo genetic testing in each of the three scenarios. Scenario 2 was the least acceptable with 78% of participants agreeing to genetic testing. The probability of agreeing to genetic testing decreased with age. Between 72 and 96% of participants reported a WTP for genetic testing. Average WTP was £539, £1516, and £6895 for scenarios 1, 2, and 3 respectively. Older participants and participants with higher incomes were willing to pay more for testing. Qualitative data provided additional detail about the rationale behind participants’ decisions. The study suggests that patients with inherited retinal disease were willing to undergo and to pay for diagnostic genetic testing, suggesting that they valued the information it may provide. However, several patients preferred not to receive prognostic information and were less willing to pay for genetic testing that yielded such detail
