MAY 27, 2009 -- While microwave will remain the most common last-mile link medium, Ethernet is playing an increasing role in supporting backhaul needs for cellular and WiMAX networks. More than half of cellular backhaul capacity will use Ethernet by the end of 2011, reports In-Stat (search Lightwave for In-Stat). The transition to Ethernet will vary by region, depending on where mobile operators are in their transition to 3G and LTE networks.
"Backhaul is getting renewed attention as mobile operators plan for a more data-intensive network," says Daryl Schoolar, In-Stat analyst. "The old voice-based solutions cannot support the growth in data traffic operators currently face."
Cellular backhaul provides the crucial link between the mobile operator's radio access network and its core network. Some of the key findings from In-Stat's new research include:
- 90,000 Gbps of capacity in the last mile of the backhaul network will be needed by the end of 2013 to support the world's cellular and WiMAX networks.
- In Asia Pacific, the cellular backhaul last-mile backhaul capacity for LTE will be 2,500 Gbps in 2013.
- Scalability is very important for operators when selecting a backhaul technology. Operators want a clear and easy path to increase backhaul capacity.
- For voice over Ethernet, operators are starting to focus on IEEE 1588v2 and Synchronous Ethernet.
