According to Insight Research, U.S. enterprises are expected to spend more than $49 billion over the next five years on Ethernet services. Ethernet metro area and wide area services are ubiquitous, available from all major data service providers, including cable MSOs, who are building a formidable base around Ethernet services in the small to mid-sized business market. Industry revenue is expected to grow from nearly $5.5 billion in 2013 to more than $13 billion by 2018.According to Insight Research's market analysis study, "US Carriers and Ethernet Services, 2013-2018," Ethernet's popularity is driven by its ability to meet growing bandwidth demands at lower cost and with greater flexibility than legacy TDM-based services. The large-scale migration of wireless backhaul cell sites from TDM to Ethernet continues to be a major factor in the next five years, as carriers complete their 4G LTE deployments.
