Ericsson Spectrum Sharing
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.
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.
