Siklu: The Advantages of E-Band Wireless Systems in Mobile Backhaul Applications

To meet growing subscriber demand, mobile operators are constantly seeking additional network capacity to enable the delivery of bandwidth-intensive data services. Nowhere are these challenges felt more acutely than in the backhaul network. Understanding the advantages, operators are migrating to all-Ethernet/IP backhaul networks. However, "traditional" packet-based backhaul transport suffers from a number of inherent limitations. In places where there is fiber coverage, fiber can provide the required capacity and more. However, fiber reach is often limited, and deploying new fiber links is often prohibitively expensive. Copper has limited capacity and reach, and "traditional" microwave links suffer from spectrum congestion and limited channel size.

Today, as the demand for bandwidth increases daily, operators who rely on wireless backhaul are turning to new frequency spectrums to lower their wireless backhaul costs. Wireless systems operating in the newly-allocated E-Band spectrum (71-76 GHz, 81-86 GHz and 92-95 GHz) - also referred to as millimeter-wave wireless systems - have clear technological and economic advantages. As such, the E-Band spectrum is expected to become the "Next Generation Wireless Backhaul Spectrum" playing an important role in easing the backhaul pain of mobile operators.
