COMMUNICATIONS

 

The deregulation of communications encouraged CTI MÓVIL to expand its already important national network to the Buenos Aires Metropolitan Area (AMBA).

The development of this project was based on technology provided by LUCENT TECHNOLOGIES, and involved about 200 PCS cells in the Buenos Aires Metropolitan Area.

TECHINT S.A. was in charge of the construction, which in turn trusted COINTEC with the information gathering, design and multidisciplinary engineering of 24 of the most complex stations of the AMBA.

SEARCH OF SITES

 

Both PCS and Fiber Optic Transmission systems require retransmission and regenerating stations.

The location and acquisition of suitable sites are milestones of a good design. For this reason COINTEC not only develops the basic and detail engineering for theses sites; but has also developed important management tools for the search, auditing, redesign and Purchase/Lease Administration of sites destined to these facilities, both in urban and rural areas, throughout the country.

COINTEC has carried out auditing on sites for PCS inside of CRM – Movicom  in the cities of Córdoba, Rosario, Santa Fe and Paraná, with highly satisfactory results.

Futhermore, TECHINT – TESUR entrusted COINTEC with the search of sites for the regenerating stations of Abasto – Rosario Fiber Optics lay out, of SOUTHERN – CONE. 

 

 

 

 

 

 

 

 

Due to Market deregulation in Argentina, many telecommunication companies started the construction of fiber optic networks for the transmission of data and communication.

For this reason COINTEC has developed a design and in-work site inspection structure for this kind of projects.

The staff that forms this structure has specific experience in inspection of fiber optic projects done previously by companies such as TELECOM and TELEFONICA ARGENTINA.

Human Capital and COINTEC’s experience in planning as well as in technical investment control concerning telecommunication works, results in a highly convenient approach to ensure the best result for the investment undertaken.

IMPSAT 

 

  •  Control Data and Communications Buildings Transference

 

Communication’s new challenge and in particular the one on data transference, have taken IMPSAT to undertake an important project called IMPSAT 2000. This project results in the creation of a fiber optics network in Argentina which extends to Latin America and specially Brazil as well as Venezuela.

IMPSAT put COINTEC in charge of the bidding contract of the Control, Data Transfer and Communication Buildings.

These buildings are meant to hold the telecommunication equipment which responds to UIT-T (Union Internacional de Telecomunicaciones) Standards and ETSI-European Telecommunication Standards as regards electromagnetic shielding.

Furthermore, they have the most sophisticated alternative power supply services with power generating sets and UPS systems, fire detection and extinguishing system for electronic equipment, Perimeter Security System, Closed TV Circuits and Electronic Systems for Access Control.

PCS INTERIOR 2000 Project

Linking for DATA NETWORK AMBA Project

Fiber Optic Network AMBA Project

 

Keeping on with its expansion project in the Argentinean telecommunications market, MOVICOM BELLSOUTH faced many projects on mobile phone service in PCS band and data transmission.

This second stage of enlargement of the Buenos Aires Metropolitan Area (AMBA) PCS network was carried out with outdoor technology from LUCENT TECHNOLOGIES. COINTEC was selected to collaborate very closely with these undertakings, being in charge of different aspects.

This collaboration refers to:

  • Basic studies
  • Economic studies
  • Auditing on Technical Feasibility for the installation of PCS Cells.
  • Programming and Control on Engineering Advancement, Supplies, Construction and Assembly.
  • Survey of Sites and existing Structures.
  • Design and Calculations of Masts, Towers and Monopoles.
  • Multidisciplinary Engineering of PCS Cells and Links for Data Networking.
  • Inspections in Supply Factory.
  • Supervision of PCS Cells Construction.
  • Supervision of MTSO’s Construction.
  • Orientation of Antennas.
  • Measurements of the System’s SWR and Attenuation.
  • Supervision of the Fiber Optics Lay Out.

 

These projects are currently being carried out, thus establishing a very close and productive relationship between both companies and have involved, until now, the construction of 300 stations throughout Argentina.

PCS – Personal Communication System

Due to an ever-increasing competitive- ness in the argentinian cellular phone market as a consequence of the opening of the telecommunications market, MOVICOM – BELLSOUTH started in 1999 an enlargement plan for its PCS cellular network in the Buenos Aires Metropolitan Area (AMBA).

MOVICOM – BELLSOUTH chose COINTEC as one of its collaborating companies to carry out the demanding infrastructure works program.

Setting a control mechanism that allows quick error-correction decisions, while keeping in sight a global overview of their progression is of outmost importance in decentralized projects that have to be carried out in hundreds of different sites and with a very little time to do them.

Within the services provided by COINTEC, a programming & follow-up method was included, adapted not only to this kind of projects, but also to the MOVICOM – BELLSOUTH operative structure.

This system included:

 

  • Planning, programming and follow up of works, including:

–         Gathering of internal information on methods and timing.

–         Registration and updating of the engineering state, and contracting & purchases.

–         General planning.

–         Detailed programming for general control purposes.

–         Programming ordered according to priorities and work supervisors for construction control.

–         Programming ordered according to responsible sectors and contractors for operation control.

–         Weekly gathering of progress information and progress auditing.

–         Weekly performance control on contractors in charge of systematic tasks and recommendations on crew required.

–         Weekly progress reports with graphic visualizations on task progress, contractors, in-site drawbacks and (works) status.

 

  • Budget control

In addition to participating in these services, COINTEC also took part in the following tasks:

 

  • Supervision in the construction of PCS cells, including:

–         Supplies requirements and engineering completion.

–         Activation of supplies and contractors.

–         Data gathering.

–         Technical supervision of works, in civil constructions, assembly of metal structures, assembly of lines and antennas, gain and standing wave ratio measurements, energy and complementary works enlargement or installation, technology shifts for antennas and energy, assembly of shelters and construction of cabins, etc.

–         Progress reports.

–         Coordination with proprietors, services companies, town halls and other institutions.

 

 

 

 

 

 

 

 

 

 

 

 

We could (without any fear of being mistaken) describe as extraordinary the progress that communications have undergone in the last few years.

Improvement on mobile communications in frequency bands that allow the transfer of a great deal of data, the advancement of fiber optics and the geometrical expansion of Internet are the three pillars that back this development.

COINTEC has encompassed this progress by evolving along with market requirements, and by developing its services adapted specifically to the new demands.

Thus, it currently includes a permanent staff of professionals from the most diverse disciplines who have combined and specialized in the rendering of services under new requirements.
