Overview
Robust Backhaul, Today!

The INTRALINK™ product family of Point-to-Point MW radios - from 6 GHz to 38 GHz - delivers reliable wireless connections as required by the demanding backhaul and private network applications.

The products are using advanced radio technology transporting native TDM and native Ethernet traffic, allowing for a cost-effective backhaul of 2G / 3G & 4G networks.

The INTRALINK™ rich-feature and future-proof platform meets the operators' most stringent demands by offering unparalleled configuration flexibility to support complex network architectures. With the ability to handle any TDM & Ethernet traffic mix, INTRALINK™ enables wireless carriers to implement PDH / Super PDH / SDH and pure Ethernet access and aggregation networks.
