Smart Communications Inc., the wireless unit of PLDT, has started testing a remote-controlled robotic arm system on its cell sites to adjust antennas in real time and improve coverage, especially in underserved areas.
The Optical Compass and Robot Arm system, or OCRA, allows network teams to move antennas remotely instead of sending crews to sites for manual adjustments. PLDT and Smart worked with OCRA manufacturer HUMAX Networks and system integrator Telkha to run a proof of concept to see how the system can help improve coverage, reduce operating costs, and support overall network performance.
“By leading the adoption of advanced technologies like OCRA, we are shaping a future where every Filipino has access to reliable, high-quality connectivity, wherever they are,” said Menardo “Butch” Jimenez, chief operating officer and network head of PLDT.
For the pilot, Smart installed OCRA on an existing cell site to serve two locations: a hospital in San Juan and a nearby high-rise condominium. Initial findings pointed to the need for more flexible antenna setups in these areas.
Traditional antennas are fixed in place and can only be adjusted through site visits, which can be costly and slow. With OCRA, Smart can fine-tune antenna direction remotely, helping reduce downtime and improve service quality.
After installing OCRA together with the Vega High Gain Antenna previously tested in Dipaculao, Aurora province, Smart reported better signal strength, improved quality, and faster data speeds in both locations.
The system also enables Smart shift antenna coverage based on changes in network use throughout the day. This helps the company manage its network more efficiently and direct signal where it is most needed.
“Enabling remote antenna adjustments also reduces the need for physical site visits and helps telcos avoid unnecessary base station installations, saving time and expense,” said Radames Zalameda, head of the Network Strategy and Transformation Office at Smart. “These efficiencies allow Smart to reinvest in expanding and enhancing its network, ultimately benefiting consumers.”
OCRA is also expected to support Smart’s move toward AI-driven network optimization by providing real-time data on antenna direction, which is important for automated network management. The company said this test will help strengthen its 5G rollout and prepare for future 6G developments.
“HUMAX Networks, through advanced OCRA, addresses critical operator challenges in disaster recovery, accessibility, and safety while delivering significant OPEX and CAPEX savings,” said Lee Seungjae, CEO of HUMAX Networks.
