Problem addressed
Wideband 5G services require the use of a large amount of spectrum. 5G licensed cellular bands are limited and expensive. The major costs of 5G services are the spectrum licensing fee and new equipment cost. Both are high. Industry attention is focused on the public network, with little attention to and support for private and enterprise network deployment.
Innovation
- 5G NR unlicensed spectrum (NR-U) access technologies
- 5G NR / 4G LTE Dynamic Spectrum Sharing (DSS) technologies
- Multi-Operator Radio Access Network (MORAN) / Multi-Operator Core Netowk (MOCN) fo enabling multiple operators to share a 5G network
Key impact
- Equipment costs are reduced due to ASTRI’s commercial grade reference design.
- Customers benefit from reduced service costs.
- Allows 5G trials and private network deployment through free unlicensed bands.
- Existing 4G and emerging 5G operators share the same band.
- Offers smooth and progressive transition from 4G to 5G spectrum usage for operators. Speeds up NR deployment with existing LTE bands.
Application
- Spectrum sharing
- Private network deployment
- Enterprise network deployment consultation
- 5G network sharing
