Teleum Smart Distribution Box, remote inspection and recovery possible
Temporary permit granted by the ICT Regulatory Sandbox Review Committee
Official contract with SKT, expanded application to unmanned base stations


A solution that enables remote inspection and recovery when a power failure occurs in a 5G base station is being applied in the field.

The Ministry of Science and ICT announced on the 16th that Vice Minister Jang Seok-young visited 'Tellaum,' a company designated for the ICT regulatory sandbox, to listen to the company's difficulties and encourage the employees.

Telraum's 'Smart Distribution Box' combines IoT technology with an automatic recovery circuit breaker installed in the power boxes of telecommunication companies' unmanned base stations to remotely monitor power status and automatically restore it, and the service was launched last October.

The current Electrical Appliances Safety Act does not have safety standards for 'automatic reset earth leakage circuit breakers with remote control functions,' and there are no standards regarding the installation and operation of remote earth leakage circuit breakers under the Electric Power Business Act, so it was not possible to launch or operate earth leakage circuit breaker products that perform additional remote resets after three automatic resets.

In May last year, the Ministry of Science and ICT granted temporary permission at the 3rd ICT Regulatory Sandbox Review Committee for the development and application of an unmanned base station remote power management system, 5G It has become possible to provide efficient and stable communication quality in response to the rapid increase in base stations.

Since the market launch of the smart distribution box, Telraum has conducted a pilot project targeting SK Telecom’s unmanned base stations in areas prone to frequent lightning strikes and where it is difficult to dispatch maintenance personnel, and plans to apply and expand it to unmanned base stations through a formal contract.

With the application of an IoT-based remote power management system for unmanned base stations, base station management efficiency is expected to improve, costs will be reduced by preventing unnecessary dispatches, and stable 5G communication services will be made possible.
