Lack of physical space on towers to deploy additional massive MIMO antennas

Passive-active antenna in single panel. Great solution by Commscope and Nokia for operators having space constraints on tower.

CommScope and Nokia have teamed up to develop a new interleaved passive-active antenna (IPAA) radio platform. CommScope brings its antenna expertise, and Nokia provides the radios. Operators can replace their current passive antennas on towers with the new IPAA 5G NR equipment that includes both passive and passive-active antennas.

The hybrid solution consists of two modules:
· A purely passive module that supports multiple bands in the range from 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.

These modules are “interleaved” in the same enclosure.
