Nokia introduces integrated access and backhaul for 5G mmWave networks
Nokia has introduced a technology combining 5G network data traffic and backhaul connectivity within the same frequency band, enabling cost-effective millimeter-wave network deployments.
Espoo, Finland – Nokia Oyj has highlighted its Integrated Access and Backhaul (IAB) technology, designed to accelerate and reduce the cost of deploying 5G millimeter wave (mmWave) networks.
Previously, mmWave networks required dense base station deployments and costly fiber optic connections for data transfer between base stations to ensure sufficient speed and reliability. This new technology, developed according to the 3GPP Rel-16 standard, allows base stations to share the same spectrum for both user connections and backhaul traffic linking to other base stations.
The IAB solution reduces reliance on expensive fiber infrastructure and allows mmWave base stations to be deployed over a wider area. This significantly lowers network construction costs, making the implementation of 5G mmWave technology more economically viable. The solution also enables operators to utilize their existing mmWave spectrum licenses more efficiently.
According to Nokia, IAB technology aids in rapidly establishing coverage and facilitating the effective utilization of substantial traffic volumes. Future enhancements to the standardization are also planned in upcoming 3GPP releases, which will expand use cases and improve performance.
Nokia has been actively involved in the development of the IAB standard and considers the technology an effective tool for the cost-efficient deployment of 5G NR mmWave networks.
