A Telecomasia article, Global operators face challenge on increasing backhaul capacities based on a recent study by ABI, argues that operators around the world are facing bandwidth constraints in their backhaul networks due to the growth of data traffic and bandwidth intensive services like multimedia content. Backhaul are the high-capacity pipes phone companies and Internet service providers use to haul traffic over large distances. Backhaul capacity in this context refers to the networks within a country or within a contiguous region. Backhaul is distinct from the under the ocean submarine cables which currently have excess, unused capacity thanks to the dot-com bubble driven investments into this high capacity links that connect continents. A number of technologies are proposed for the backhaul links that are suited for specific regions based on what kind of infrastructure already exists.
