Global designer and manufacturer of total-package solutions for wireless and broadcast infrastructure, Radio Frequency Systems (RFS), has announced the availability of 1 and 2ft antennas with higher performance radiation characteristics according to ETSI EN 202217 Class 4 standards. The company’s SerenityLine family of Class 4 microwave antennas continue to provide the market’s best RF performance and allow mobile operators to increase the link capacity of a network by deploying new microwave links where high levels of interference are present.

While RFS’ high quality ETSI Class 3 antennas are sufficient for most of today’s network scenarios, Class 4 antennas will allow RFS customers to offer the highest performance in even the most congested environments. The higher side lobe suppression of SerenityLine antennas supports networks in ultra-dense areas and enables earlier reuse of frequencies.

The lower interference increases the carrier-to-interference-ratio and allows smaller antennas with better link throughput, reducing tower leasing fees. The lower interference also enables higher modulation schemes, increasing the data capacity per antenna.

The lightweight, easy-to-install 1 and 2ft SerenityLine antennas minimise the total cost of ownership by improving network efficiency, facilitating better re-use of a frequency channel, and decreasing installation expenses. The latest offerings are available in both single (SL) and dual polarisation (SLX) versions.

“At RFS, we pride ourselves on offering a complete portfolio of high quality, innovative microwave products that not only address the requirements that operators and system integrators have today, but also well-positions them for the future,” said Benoit Bled, Product Line Manager, Microwave Antenna Systems, RFS. “Our SerenityLine antennas have a flexible feed design, better radiation performance, and allow for in-field updates so our customers can make the most of the limited spectrum they have available and embrace next-gen radio by easily upgrading from single to dual polarisation in the field.”

In addition to its antennas, RFS provides a complete, end-to-end microwave product portfolio, including elliptical waveguides, connectors, components and accessories to support wireless network deployments and upgrades.
