The combination of an increasing global subscriber base, expansion of advanced wireless networks and the proliferation of powerful devices offering high-speed wireless internet access has dramatically increased mobile data traffic. This increase in data traffic is straining the existing wireless network infrastructure. As a result, operators are expanding their network capacity by acquiring additional wireless spectrum and by aggressively deploying LTE, TD-LTE and LTE-A networks.
In addition to the traditional macro network, which is used for wide area coverage, the roll out of smaller base station formats are being pursued. These formats include pico cell, small cell and carrier-grade Wi-Fi solutions to support growing data requirements in urban areas. These products will increase the data capacity and will be used in areas with poor coverage.
Wireless backhaul is one of many options to connect the base station to the core network, and, as data consumption grows, so does the need for high-speed backhaul. Line of sight (LOS) microwave solutions are used extensively and offer high data rate wireless backhaul solutions. With the roll out of small cells in urban environments where LOS is not always simple to achieve, non-line of sight (NLOS) solutions are being deployed, which offer lower date rates but can be used to increase the flexibility of the backhaul deployment.
