CommScope and Nokia have teamed up to develop a new interleaved passive-active antenna (IPAA) radio platform. The modular IPAA simplifies the introduction of 5G NR by enabling its deployment on the existing sites – without the need for additional footprint. This means operators can roll-out 5G services faster and keep pace with the increasing subscriber demand for mobile broadband.
This hybrid solution consists of two field-replaceable modules:
- A purely passive module that supports multiple bands in the range 700 MHz to 2.7 GHz.
- A passive-active module that includes TDD beamforming functionality for 5G n78 (3.4-3.8 GHz). This passive-active module also includes an extension of the low band arrays to avoid re-optimizing existing networks at 700-900 MHz.
Both modules can be customized to support various combinations of low- and mid-band capabilities and different radio options for 5G band n78, ranging from 8T8R to 64T64R. This capability allows operators to fully utilize limited space on cell towers and ease typical deployment challenges.
“Integration of active and passive antennas will be a major challenge for the industry over the next five years,” said Joe Madden, Founder and Chief Analyst for Mobile Experts. “The laws of physics can create some difficulties in making integrated antennas small and lightweight…but operators will need the integration to add capacity on their crowded towers. We expect clever engineering to create opportunities for the most innovative antenna suppliers.”
