What is IAB (Integrated Access and Backhaul)?

IAB is a significant Rel-16 element in 5G New Radio (NR). It empowers quick and cost-effective millimeter wave deployments through self-backhauling in the similar spectrum. IAB permits administrators to use their current mmWave range licenses. It also permits administrators to have the opportunity to send separate backhaul where required, without extra interference analysis that can be subject to regulatory review. IAB takes into account multi-hop backhauling utilizing the similar frequencies employed for utilized equipment (UE) access or a distinct, dedicated, recurrence.
