2. Planejamento e gerenciamento de recursos para redes IEEE 802.16 baseadas em rádio sobre fibra / Resource planning and management for IEEE 802.16 networks based on radio over fiber
The Radio over Fiber technology allows the reduction of the cost of installation and maintenance of wireless access networks, since it can allow an optimized use of radio frequency (RF). Moreover, it employs simplified and inexpensive antennas. The IEEE 802.16 wireless networks, known as WiMAX, are low cost solutions for the last mile access to the Internet.

5. Design of an optical transceiver for free space optical digital communication. / Projeto de um transceptor óptico para comunicação digital em espaço livre.
Os sistemas de comunicação óptica por espaço livre, comumente denominados sistemas FSO (Free Space Optics), servem para estabelecer enlaces de comunicação do tipo wireless, ponto-a-ponto, a uma elevada taxa de dados e com alcances que podem variar de algumas centenas de metros a alguns quilômetros. O interesse pela tecnologia FSO tem sido estimulado p

6. SIMULATION AND DEVELOPMENT OF A FREE-SPACE OPTICS IN RIO DE JANEIRO AND RELATIONSHIP WITH ITU-T G.826 / SIMULAÇÃO E DESENVOLVIMENTO DE UM ENLACE DE FREE-SPACE OPTICS NO RIO DE JANEIRO E A RELAÇÃO COM A ITU-T G.826
Very few works had been developed in Brazil, dealing with Free-Space Optics (FSO). In this arrangement, a laser beam carries information for a short range (up to 3-4 km), avoiding the use of optical fiber. FSO is a rapidly-improved solution and very economical, specifically in urban areas. In this work a FSO system operating in Rio is described. This work pr
