Efficiency in radio technology and heterogeneous networks (HetNet) for wireless communication has long been talked of. I first heard of it at the London Communication Symposium in 2009 at the University College London (UCL) where HIPNet (Heterogeneous IP Networks) was vastly discussed – more in theory than in-practice, at the time.
HetNets enable wireless networks of varying cell sizes, output power and radio access technologies to work together towards the goal of boosting network coverage and capacity. With many wireless operators believing that small cells would be an essential part of their future strategy, there is a big industry push towards HetNets. LTE Advanced will further drive the deployment and adoption of heterogeneous networks.
This article speak of HetNet as an essential element to ensure mobile broadband QoS.
