International experience and track record. Able to serve several regions at once since 1992.
Full capability end to end
The only provider integrating the entire chain on radio base station projects.
Site Acquisition, Permitting and Negotiation
The first phase of the rollout cycle, site acquisition: we find the locations that meet the coverage target, negotiate the lease with the owner and handle the full permitting process until the site is ready to build. It is the stage that delays a rollout most when it is underestimated, and the one we have been solving since 1992.
Site hunting by coverage
Geospatial analysis with GIS technology to find candidate sites that meet the carrier's coverage and capacity target, assessing available height, line of sight and access.
CloudRF · GIS
Site survey and technical feasibility
Field visit with a photographic survey, checking vehicle access, availability of an electrical service entrance, space for the foundation and ground conditions.
Site acquisition
Lease and colocation agreements with owners of land and rooftops, including rights of way for the electrical service entrance and the fiber.
End-to-end permitting
Municipal authorities (zoning variables and building permit), INAC for height restrictions, the Ministry of Ecosocialism, municipal councils and other regulators.

Civil, Electrical and Mechanical Infrastructure Engineering
Design and construction of all the infrastructure that supports and powers a radio base station: from the soil survey and the tower foundation to the grounding system and the distribution switchboards. Multidisciplinary works (civil, mechanical and electrical) under a single contract, without splitting responsibility among several contractors.
Soil survey, earthworks and foundations
Standard Penetration Test (SPT) and soil classification to determine the bearing capacity. That figure sets the bearing depth and sizes the footing. It covers excavation, compaction, formwork, reinforcement and concrete pouring. This is the item that literally holds up everything else: an undersized foundation compromises the entire tower.
SPT · COVENIN 1756 · ACI 318
Power and metering
Low or medium voltage service entrance, DC and AC power systems, distribution switchboards, metering equipment and protection coordinated to the National Electrical Code.
Grounding system
Design and installation of ground grids and lightning protection, with soil resistivity measurement and verification of ground resistance to IEEE 80/81.
IEEE 80 · IEC 62305
Multidisciplinary works (civil, mechanical and electrical)
Full delivery under one contract: self-supporting and guyed structures, perimeter fencing, equipment shelter, raceways and mechanical assembly.

VenIoT® — Remote Infrastructure Monitoring and Control
Our own Internet of Things (IoT) platform to monitor and operate critical infrastructure remotely: power, climate, security and processes. It began as a problem of our own — knowing what was happening at hundreds of scattered radio base stations without sending someone — and today it is a product running at telecommunications sites, industrial plants and oil fields.
See VenIoT Demo →Power and climate monitoring
Measurement of electrical variables (voltage, current, frequency, kWh), genset and battery bank status, shelter temperature and air conditioning operation.
Security and access control
Cabinet and door opening, intrusion and smoke detection, with a record of who entered and when. It cuts copper and battery theft, the biggest loss at remote sites.
Remote control and automation
It does more than watch: it lets you switch equipment on, off and reprogram it remotely (genset start, load transfer, equipment reset), with confirmation that the command was carried out.
IoT: LoRa, WiFi 6, 4G/5G and satellite
The link is chosen to suit the site: LoRa for long range and low power in open field, WiFi 6 inside the plant, 4G/5G where there is coverage, and satellite where there is none.
LoRaWAN · MQTT · Modbus
Works without a permanent connection
The node decides on site according to the rules loaded into it and syncs when the link comes back. In Venezuela, where both connectivity and power are intermittent, that autonomy is the difference between a system that works and one that does not.
