Ericsson Spectrum Sharing for immersive, wide-area 5G coverage

With 5G networks going live and consumers getting their hands on the first 5G devices, user expectations are high. Communications service providers need to make the best use of their spectrum assets and utilize each band’s performance characteristics to support their business strategies, while maintaining coexistence between all technologies deployed in the network. Ericsson Spectrum Sharing (ESS) allows operators to run LTE and NR simultaneously on the same carrier frequencies and base station hardware.

With a simple software installation, ESS offers quick introduction of 5G over a wide area, for all 5G-enabled devices leveraging 4G spectrum and existing Ericsson Radio System infrastructure.

The challenge

Operators will need new spectrum for 5G, not least because its high expectations are fully achieved in the new mid- and high-bands.

In millimeter-wave frequencies, with extremely wide bands, operators will achieve 5G’s ultra-high peak rates and low latency. This will create new capacity and throughput levels for mobile broadband, especially as a way of offloading congested 4G networks (and for new special use cases).

But there is also broad interest in deploying 5G technology in new mid-bands (3.5–6GHz), an optimal compromise between coverage, capacity and latency; as well as existing mid-bands (1.8–2.6GHz), to achieve wide 5G coverage as rapidly as possible.

The solution

ESS is a unique solution, including coordinated scheduling with 1ms granularity and frequency division multiplexing. Deploying ESS in a network is highly TCO efficient – existing Ericsson Radio System baseband and radio units can be upgraded with software to support ESS, without the need for additional hardware.

With a simple software update and based on unique, intelligent scheduler algorithms, ESS permits dynamic spectrum allocation to 4G and 5G on the same band.

ESS and inter-band NR carrier aggregation enable a fast introduction of 5G and smooth evolution of 5G networks which maximize the infrastructure usage and spectrum assets. This hands service providers the control to introduce 5G coverage at a pace that suits their business needs.

Migration from 4G/LTE to 5G NR can be made simpler, more efficient and faster by giving both technologies instant access to the same spectrum.
