pipelines, fiber optic cables and manholes paid to the city for underground use.
Due to this infovia, many municipal public agencies are integrated into a digital
telephony network that sum up an annual saving of R$ 1,7 millions in phone bills
to the public funding.
In the State of Rio de Janeiro, the INFOVIA-RJ Program was developed, which
establishes the integration of Rede Governo and Rede Rio structures, adopting a
single optical ring, using DWDM (Wavelength Division Multiplexing) technology
with rates up to 40 Gbps. INFOVIA-RJ allows for a reliable access to broadband
Internet and connects state agencies, educational and research institutions and
organizations. The main focus of INFOVIA-RJ investments in this new year are
the Digital City project expansion and the building of “digital corridors” through
several cities - the project aims to involve 92 cities in the state by the end of the
government management - which will have public lightning by wireless networking
technologies, replicating the project firstly implemented in Piraí and Rio das Flores
throughout Rio de Janeiro. Some of the next cities to be served by the Digital City
project are Valença, Vassouras, Rio Claro and Barra do Piraí. They will form the first
major “digital corridor” of the state, taking advantage of already covered areas to
expand the range of the network with lower cost 5 .
These experiences of implementing local area networks for voice and data transmission
happened through public and private sectors. Firstly, this expansion took
place by the local private sector, opening market for small and medium-sized regional
companies. In Corpus Christi, Texas 6 , for example, with a population of 300,000,
a wireless network was installed for voice and data transmission to automated reading
from gas and water gauges so doing a daily control of consumption curve is
possible. This telemetry service allows the gas use and water flow monitoring. With
information about system’s idle capacity, it was possible to expand access to public
buildings and schools.
These actions started their diffusion over different public service networks: education
management system, health care card, and security systems with data sharing
