Abstract
This paper addresses the deployment of hybrid
WiMAX and Wi-Fi networks for the support of always best
connected telemedicine and health sciences education
applications. The available services include a LMS (Learning
Management System) and several structured functionalities for
b-Learning. For the support of these services, fixed and wireless
LANs have been deployed, as well as an experimental point-to-
multipoint IEEE 802.16-2004 network covering part of the city
of Covilhã. The FCS (Health Sciences Faculty) Campus as well
as the tutorial rooms of the Faculty spread at the different
Hospitals of the region of Beira Interior, Portugal, are
benefiting from WLAN coverage, whose backhaul is supported
by WiMAX point-to-point links with relays. Field trials results
were compared with the ones arising from the WiMAX radio
links design, and very similar results were achieved. Service
quality was guaranteed by adjusting QoS parameters.
