What is IAB – MT ?
Integrated Access Backhaul allows for single or multi-hop backhauling using the same frequencies employed for user equipment (UE) access or a distinct, dedicated, frequency.
IAB leverages the spectral efficiencies of new radio and the increased capacity afforded by the higher bands available in 5G to deliver an alternative to optical cell site backhaul. This alleviates one of the primary issues surrounding the deployment of 5G that can be employed as a short-term alternative to fiber or as a permanent option for more isolated antennas or those without right of way access.
Any future migration is aided by IAB’s adoption of the Internet Protocol (IP) over a new Backhaul Adaption Protocol (BAP) layer defined within 3GPP TS 38.340.

mmwave signals have limited reach. A chain of relays/IAB is the solution. It allows for single or multi-hop backhauling using the same frequencies employed for user equipment (UE) access or a distinct, dedicated, frequency.
