Lately advancements in cellular technologies have resulted in significant increase in connection speeds over the air. This paper briefly describes how the mobile backhaul networks have to catch up with all these changes and thus tend to counterbalance the enhancements on the rest of the network. A large number of the existing backhaul networks are based on legacy technologies, incapable of supporting higher speeds or service requirements. Explosion of packet data traffic over voice, unlimited data/voice services, faster download rates have fuelled the demand for higher backhaul network capacity and intelligence.
