Ericsson Spectrum Sharing – A better way to build 5G
Ericsson Spectrum Sharing completely transforms the way 5G is introduced across the world. It brings 5G to everyone, everywhere, much faster. Ericsson Spectrum Sharing introduces a new way of rolling out 5G that re-uses hardware/spectrum/sites, increases coverage of mid/high band, and offer a clear path to 5G stand alone, allowing operators to shift capex investments from new sites to new 5G stand alone use cases.
The majority of new frequency bands allocated to 5G are in mid- and high-bands. To enable cost-efficient, wide-area 5G coverage and improve mid- and high-band spectrum utilization, it is necessary to also operate 5G in lower frequency bands. However, most operators today have long term evolution (LTE) technology in those lower bands. Entirely re-farming carriers from LTE to NR is not currently feasible due to the high penetration of existing LTE devices and the high traffic volume that they generate.
ESS transforms the end-user experience. Firstly, by opening up wide-area 5G coverage to give end-users unprecedented access to enhanced 5G use cases. Secondly, by enabling 1ms scheduling for best spectral efficiency as well as to enable new, low latency 5G SA use cases. Finally, when paired with carrier aggregation, enabling higher peak rates across a larger coverage area.
To enable cost-efficient, wide-area 5G coverage it’s necessary for 5G to also operate in lower frequency bands where most operators have currently deployed LTE technology. Entirely re-farming carriers is not feasible due to the high penetration of existing LTE users and the high traffic volume they generate. ESS therefore allows the introduction of 5G on existing 4G bands without re-farming carriers and with minimal impact on live end-user service.
For a 5G SA implementation, ESS can rapidly enable the continuous coverage required, bringing the full advantage of network slicing and lower latency to power new business opportunities across a multitude of industries in cities, on factory floors and roads worldwide. The coordination of devices at 1ms is a key ESS capability that will support these low latency use cases.
