In th is paper, we explore the feasibility of designing an outdoor cellular network based on the IEEE 802.11 standard, which was developed originally for wireless local -area networks. For channels typical in cellular networks, we study the radio link power budg et and, via simulation, the bit -error performance of three kinds of receiver: (1) the(More)
This paper explores the feasibility of designing an outdoor cellular network based on the IEEE 802.11 standard, which was developed originally for wireless localarea networks. Specifically, the performance of the 802.11 radio and multiple access control (MAC) protocol in outdoor environments is investigated. For channels typical in cellular networks, we(More)
A patient with Rubinstein-Taybi syndrome is presented with the characteristic clinical features including small and short stature, severe mental retardation, and small maxilla with a dental malocclusion. Treatment for this patient was accomplished utilizing a general anesthetic. These special patients who lack the ability to accept dental treatment in the(More)
The purpose of this investigation was to determine the type and prevalence of dental injuries seen in a hospital emergency room. Of the 10,436 patients who were treated at the hospital emergency room as a result of a traumatic episode, 765 (7.3%) had sustained injuries to structures of the oral cavity. The leading cause of dental injury was falls,(More)
This paper outlines a study of minimum meansquare error (MMSE) diversity combining for wide-band digital cellular radio, designed to combat intersymbol interference (ISI) caused by frequency selective fading. The systems we analyze use 1) binary phase shift keying (BPSK), quarternary phase shift keying (QPSK) or 16 level quadrature amplitude modulation (16(More)
