Eyeing 5G Trials In Markets Including India, RFS Launches Active Passive Antenna

Radio Frequency Systems (RFS), a designer and manufacturer of wireless and broadcast infrastructure solutions, announces its Active Passive Antenna (APA) solution that aims at solving potential antenna issues in 5G deployments.

The APA features a modular architecture that allows mobile operators to deploy any RFS passive antenna today then seamlessly upgrade the antenna with active components when required. The company claims it will have no impact on either the passive or active aspects of antenna performance.

RFS’ APA combines the passive components needed for legacy frequency transmissions with the active components needed for 3.5 GHz mMIMO transmissions in 5G networks in a single antenna. The main challenge associated with the interleaved architecture used in the APA is ensuring that frequency duplex division (FDD) transmissions that use passive components and time division duplex (TDD) transmissions that use active components do not interfere with one other and degrade performance.

High-capacity 5G TDD trials are currently underway in markets including Europe, India, the Americas and Asia where 4G and RFS believes 5G technologies will co-exist with 4G in these markets.

RFS’ evolved APA has been extensively tested and optimised to ensure the interleaved architecture does not affect the functionality or performance of either the passive or the active components in the antenna.

In addition, the antenna features a modular, plug-and-play architecture that allows mobile operators to immediately deploy RFS passive FDD antennas, then add active TDD transmission capabilities in the future without changing the appearance, size or tower leasing costs of the original antenna.

“We understand that mobile operators need the ability to easily evolve to 5G without doubling the number of antennas on already-crowded macro sites or increasing leasing costs,” says Herbert Merz, President and CEO at RFS. “With our future proof FUSION implementation, operators have a very cost-effective and practical strategy for 5G evolution. They can deploy our passive antennas today, then upgrade them as required to support 3.5 GHz mMIMO and smoothly evolve to a 5G future with no compromises to performance, no additional leasing costs and the lowest visual impact on the market.”
