Technical feasibility studies, including conceptual and functional design, line of sight analysis, service parameters and system design for any type of topology. These simulations can consider land use and obstructions modeled on 3D polygons. It considers multiple technologies (*), predicted performance, recommended security and applicable regulations (Subtel / DGAC / Town Hall).

Use of recently updated, high-resolution satellite maps to model 2D and 3D obstructions and consider land use. It uses Digital Elevation Models (DEM) such as:
-MDT: 2D-3D Digital Terrain Model. Elevations with resolutions up to 1m and recent updates.
-MDS: 2D-3D Digital Surface Model that includes all existing objects on the surface (buildings, trees, infrastructures, etc.).
-Clutter: Land use layer, for multipath / reflections / difractions calculations.

COMPLIANCE

Application for authorizations to install, operate and develop telecommunications services in Chile.

According to the legislation in Chile, any wireless telecommunications system requires authorization for its operation. Any telecommunications system in operation that is not authorized with the corresponding license, permit or concession risks fines issued by the regulator (Subtel).
Fresnel engineers are registered in Subtel, and they have extensive experience in chilean regulation. Thess includes, authorization, modification, renewal and / or regularization of all types of telecommunications systems.

 

LIMITED PERMITS

Operation authorization for wireless private networks, links and systems for voice, video and data such as; Point to point links (microwave, backhauls, etc.); Multipoint networks for CCTV, video surveillance, Voice over IP, Wireless LAN; VHF / UHF radio communications (base stations, repeaters, etc.), among others.

MEASUREMENTS AND CERTIFICATIONS

Wireless and wired

Radio spectrum measurements such as; signal power mapping, channel width, interference analysis, AM / FM / ASK / FSK demodulation, etc. Measurements and certifications for antenna wiring (distance to failure, VSWR), and also measurements and certifications for F.O. and copper wiring.

INSPECTION

Regulatory compliance

Measurements and technical visits in order to check and / or certify the regulatory compliance for telecommunications systems.

MUNICIPAL DEALING

Telecommunication infrastructure sites

Installation notice, construction permits and sensitivity report for telecommunication sites near sensitive places (example: schools or hospitals). Also, dealing process with Town Hall and/or related organizations.

TELECOMMUNICATIONS SITES ACQUISITION

Negotiated by specialists

Professional specialists carry out the whole process to acquire new sites for telecommunications sites. That is, sites search, negotiation with site owner, acquisition or lease and installation permits.
