de acuerdo a las normas de la buena ingeniería.
Existen algunas zonas que no cuentan con puntos de
presencia AUI, por lo que la conectividad de las estaciones
que cubran estas áreas debe ser inalámbrica
(backhaul).
Se implementó el backhaul inalámbrico con enlaces
“punto-a-multipunto” (PMP) o “punto-a-punto” (PtP)
en las bandas de 5.8 GHz o 5.4 GHz.
La conectividad inalámbrica convergiendo al punto
AUI más cercano cumple las condiciones de “línea de
vista despejada”. Además se han tenido en cuenta el
ancho de banda del tráfico AUI que insumirá cada estación
conectada.
3.3 Implementación
Una vez que se finalizó con el relevamiento y la provisión
de los elementos y equipamientos a utilizar, se
procedió a realizar la implementación de cada localidad
para lograr la cobertura Wi-Fi y brindar el servicio
de internet libre y gratuito a toda la comunidad.
Para ello se respeta estrictamente la solución de ingeniería
proyectada, y se instalan las estaciones base,
los enlaces y la interconexión con la Autopista de la
Información.
Se configura todo el sistema de acuerdo a lo planificado,
incluyendo los servicios que serán brindados
desde el Data Center de la AUI (ver figura 31).

There are areas that did not have AUI points of presence, reason by
which the connectivity of the stations that cover those areas had to
be wireless (Backhaul).
Wireless backhaul with “point-to-multipoint” (PMP) or Point-to-Point
(PtP) links was implemented, in the 5.8 GHz or 5.4 GHz bands.
Wireless connectivity converging to the nearest AUI point fulfills the
“line of sight” conditions. Also, the bandwidth of AUI traffic that each
station will consume was considered.
3.3 Implementation
Once the survey was finished and the necessary materials and equipment
were acquired, the implementation began in each locality in
order to have WiFi coverage and free internet service for the whole
province.
For this, the engineering solution was strictly respected and the base
stations, the links and the interconnection with the Information
Highway were installed.
The system was configured according to plan, including the services
that would be provided from the AUI’s Data Center (fig. 31).
3.4 Fine Tuning
Each station was analyzed individually, lowering the transmission
power to the minimum so that the intra-system interference, created
by other base stations, was not computed.
The coverage was measured in site, which allowed adjusting the planning,
adding stations of reduced heights in order to achieve “micro
cell” penetration, with reduced reach over the shadows of the initial
coverage. This means that the channel assignation of each station is
susceptible to analysis as new sites are added.
