      Reference to a HetNet often indicates the use of multiple types of access nodes in a wireless network. A Wide Area Network can use macrocells, picocells, and/or femtocells in order to offer wireless coverage in an environment with a wide variety of wireless coverage zones, ranging from an open outdoor environment to office buildings, homes, and underground areas. Mobile Experts defines the HetNet as a network with complex interoperation between macrocell, small cell, and in some cases WiFi network elements used together to provide a mosaic of coverage, with handoff capability between network elements.[3] A recent research study from ARCchart estimates that HetNets will help drive the mobile infrastructure market to account for nearly $57 Billion in spending globally by 2017.[4]

      Berg Insight forecasts small cell base stations to reach 40M units by 2018

      Berg Insight has reported the installed base of small cell base stations increased to about 4.1 million units worldwide in 2012. Berg Insight has forecasted small cell base station market to grow at a CAGR of 46.2 percent, the installed base is forecasted to reach 40 million units by 2018.

      “Mobile operators worldwide are experiencing rapid growth in mobile data and signaling traffic”, said André Malm, Senior Analyst, Berg Insight. He adds that total mobile data traffic in cellular networks is likely to grow at a compound annual growth rate (CAGR) of more than 50 percent from 2012 until 2018. A combination of approaches can be used to meet the rising demand for data traffic. These include acquiring more spectrum, using more advanced radio air interfaces, making the macro layer denser by installing more base stations in traffic hotspots, as well as introducing heterogeneous networks (HetNets). HetNets are composed of multiple radio access technologies, architectures, backhaul solutions and base stations of varying transmission power. Examples of low power nodes include Remote Radio Units (RRUs) and Distributed Antenna Systems (DAS), as well as small cell base stations such as microcells, picocells and femtocells.

      Small cell solutions have been available for many years. Mobile operators have for instance deployed microcells to improve coverage in outdoor locations where macrocell solutions are unsuitable mainly due to high cost. DAS have been used to enhance coverage in public indoor areas. More recently, operators have begun to deploy femtocells to improve network coverage for residential and small business customers. However, with the introduction of HetNets, operators will be able to install and manage a much larger number of small cells that increasingly become integrated nodes providing capacity enhancement to the network. “Furthermore, small cells are gradually becoming multi-mode solutions, incorporating cellular access technologies including 3G/LTE, in addition to Wi-Fi” concluded Mr Malm.
