Abstract
This paper addresses aspects of design and
planning of a Wireless network WiMAX (IEEE 802.16)
to establish a point-to-point, PTP, link from the Health
Sciences Faculty of University of Beira Interior
(FCS/UBI) to Hospital Sousa Martins (Guarda), and also
presents a field trial where we tested point-to-point links
with pre-WiMAX equipment. The design of the link had
into consideration the carrier to noise ratio, C/N, and the
minimum carrier to noise ratio with fading, C/Nmin_fad.
The use of two relays is needed to guarantee LoS
conditions. The use of BreezeNET B equipment from
Alvarion was assumed. From the dimensioning process, it
was verified that with γ = 2, for the second clause, the
three types of modulations can be used. Field trials results
were compared with the theoretical model, and very
similar conclusions were achieved.
