Smart Communications, Inc. said Monday it has begun deploying remote-controlled robotic arms on its cell site towers to enable real-time network optimization and coverage improvement, particularly in underserved areas.
The Optical Compass and Robot Arm (OCRA) system allows operators to move antennas remotely, enabling real-time adjustments. Through its Network Strategy and Architecture team, and in partnership with OCRA manufacturer HUMAX Networks and system integrator Telkha, PLDT and Smart launched a proof-of-concept for the OCRA solution. The test aims to determine how this innovation can boost coverage in target areas, cut costs and enhance overall network performance.
“At PLDT and Smart, we view innovation as a cornerstone of nation-building,” said Menardo Jimenez, PLDT chief operating officer and network head. “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.”
For the pilot test, Smart installed OCRA at an existing cell site to serve two locations: a hospital in San Juan and a nearby high-rise condominium. Results showed the need for smarter, more flexible antenna solutions.
The system addresses long-standing issues in traditional wireless setups, where antennas are fixed in place and adjustments require physical site visits — often costly and time-consuming. With OCRA, Smart can now remotely fine-tune antenna alignment and optimize coverage in real time, reducing downtime and improving the customer experience.
After installing OCRA, paired with the Vega High Gain Antenna previously tested in Dipaculao, Aurora province, Smart recorded significant improvements in signal strength, quality and speed across both locations.
The OCRA system also allowed Smart to shift antenna coverage based on usage peaks throughout the day. This dynamic coverage ensures Smart’s network resources are used efficiently, delivering timely, stronger and faster connections where customers need them most.
“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 Smart’s network strategy and transformation office. “These efficiencies allow Smart to reinvest in expanding and enhancing its network, ultimately benefiting consumers.”
OCRA also supports Smart’s transition toward smarter, AI-driven network optimization by providing real-time visibility into antenna direction — an essential capability for intelligent network management. This milestone strengthens Smart’s leadership in 5G while laying the groundwork for future 6G advancements.
The initiative also underscores Smart’s commitment to innovation and customer service excellence, turning cutting-edge technologies like OCRA into practical solutions that deliver stronger, more reliable connectivity experiences.
“HUMAX Networks is proud to partner with Smart for OCRA, which has proven to be an essential solution that strengthens the company’s network leadership through smart network optimization,” said Lee Seungjae, chief executive of HUMAX Networks.
“As a leading provider of innovative network solutions designed for precision, optimization, and operational efficiency, HUMAX Networks, through advanced OCRA, addresses critical operator challenges in disaster recovery, accessibility, and safety while delivering significant OPEX and CAPEX savings,” he said.
