2D/3D DIGITAL MODELING
2D-3D Modeling for outdoor radioelectric systems using Digital Elevation Models (DEM):
-DTM: Digital 2D-3D Terrain Model. Elevations with resolutions up to 50cm. (susceptible to add building layer from 5m meters high).
-DSM: 3D Digital Surface Model that includes all existing objects on the surface (buildings, trees, infrastructures, etc.).
Technical feasibility studies for any type of topology, including conceptual and functional design, Line of Sight analysis, service parameters, system design. It uses 2D / 3D modeling and considers feasible technologies, predicted performance, recommended security and applicable regulations (Subtel / DGAC / Municipal).
Coverage studies for radiant systems of any type and technology, using 2D / 3D digital modeling.
Planning and design of high capacity indoor and outdoor Wi-Fi networks, taking into account materials (walls, floor), doors, windows, height and direction of antennas, among others.
Measurements of coverage, performance, signal strength and capacity.
Engineering considers technologies such as:
DAB, DVB, DRM, ISDB, ATS, FM / 3G, 4G, 5G, SON / DMR ,TETRA, LTE / LTE-TD, WIMAX, GPON, EPON / OTN, MPLS, C-Eth, SDH, Microwave, SDN / M2M, NB-LTE, LORA, SIGFOX / WiFI
Application for authorizations to install, operate and develop telecommunications services in Chile.
According to the applicable legislation in Chile, any 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 with extensive experience and registered in Subtel, are responsible for entering requests for authorization, modification, renewal and / or regularization of all types of telecommunications systems.
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, etc .; VHF / UHF radio communication, (base stations, repeaters, etc.); Cable and satellite television, among others.
PUBLIC SERVICE CONCESSIONS
Concessions with and without public tender process, for telecommunications operators that provide public or intermediate telecommunications services such as; Packet switched transmission for fixed and mobile telephony and data (internet); Specialized radio communication systems; Wireless ISP (WISP); Public WIFI, among others.
Procedures in Subtel for request and support in the regulation of unregulated bands or without current regulations.
NEW CABLE DUCT LAW
Design and presentation of the project of the telecommunications system of the building (wiring and antennas, for internet, telephony, television, etc.) services and subsequent report of conformity (measurements for works reception).
Development of bidding rules or technical proposals, for public and private tenders, both for the project regulatory specifications, and for the technical requirements design (equipment, accessories, detailed engineering and plans)
MEASUREMENTS AND CERTIFICATIONS
Wireless and wired
Radio spectrum measurements (signal power mapping, channel width, interference analysis, AM / FM / ASK / FSK demodulation, etc.). Measurements and certifications for antenna wiring (distance to failure, VSWR). Measurements and certifications for F.O. and copper wiring.
Measurements and inspective visits in order to review and / or certify the regulatory compliance for telecommunications systems.
Telecommunication infrastructure sites
Installation Notice, construction permits and Sensitivity report (schools, offices, hospitals, existing antennas, in the distances determined by law) for telecommunications infrastructure sites, antennas and supporting structures. Processing in Municipal Works Department (DOM) and/or related organizations.
TELECOMMUNICATIONS SITES ACQUISITION
Negotiated by specialists
Professional specialists, carry out the whole process of implementing new sites for mobile and fixed wireless telecommunications infrastructure (sites search, negotiation with site owner, acquisition or lease and installation permits).
Intrusion test specialized in wireless systems and multiple technologies, in order to find, analyze and fix vulnerabilities. Involves different types of pentesting (Black / white / Gray box), and architectures such as IoT, IIoT, WiFI, WiMAX and propietary, among others.
Since 2009, we have participated fully in hundreds of wireless and security telecommunications projects of all sizes and complexity throughout the Chilean territory, which, added to the knowledge, expertise and management capacity of our human resources, allows us to guarantee delivery of quality, rigor, precision, diligence and seriousness in all our services.
