Multicore Technology — Much More Than 2 Carriers Together !

By Dudy Cohen 4 min read

There are lots of ways to resolve your 5G wireless backhaul challenges

but at what cost?

Mobile network modernization towards 5G gives rise to growing requirements from your wireless backhaul network. In turn, your wireless backhaul network becomes a strategic asset as it enables (or limits) your ability to achieve your business goals.

These goals, which include providing more capacity, delivering more services, and serving more customers, can be achieved in many ways. But the real challenge is achieving them with minimal use of resources such as spectrum, real estate, and tower space so that you maintain a feasible business case.

Ceragon’s multicore technology, built using vertically-integrated, in-house-designed RFIC and modem chipsets - does just that. This unique technology – which comprises an advanced, parallel radio-processing engine built around Ceragon’s in-house baseband modem and RFIC chipsets embedded in the FibeAir IP-20 platform – was designed to accommodate multiple carriers in a single box. It also offers advanced, unique capabilities such as 4x4 LoS MIMO, Advanced Frequency Reuse (AFR), and Advanced Space Diversity (ASD), while minimizing footprint and power consumption (unlike dual-carrier solutions that are merely a physical enclosure for two single-carrier products).

Multicore technology enables you to achieve 5G wireless backhaul capacity while utilizing only a ¼ of the spectrum and ½ of the real-estate and power consumption otherwise required. This is based on the field-proven 4x4 LoS MIMO capability, which uses only a fraction of the spectrum for a given capacity.


Multicore technology also allows you to densify your network and deploy sites where needed, and overcome wireless backhaul spectrum constraints by doubling the frequency reuse of this spectrum. This is based on the unique AFR feature, which leverages multicore technology to reevaluate channel parameters and mitigate the interference caused by an adjacent link. With AFR, the angular separation between links using the same frequency can decrease from 90O to as little as 15O, thus allowing more links that use the same frequency channel to co-exist in close proximity.


 Multicore technology also enables you to extend your network reach without tower space limitations by using the unique ASD technology. ASD utilizes multicore technology algorithms and beam-forming capabilities to reduce the number of radios and antennas in a space-diversity configuration by 25% (3 radios instead of 4). This translates into 25% less real estate, equipment, and power.



To conclude, Ceragon’s unique multicore technology and vertically-integrated chipsets allow you to achieve 5G wireless backhaul capabilities AND increase your operational efficiency by reducing labor, power, rent, and spectrum-related costs. This means you can future-proof your strategic asset – your wireless backhaul infrastructure – so that it answers your requirements today and in the future!
