With increased data consumption and mobile device connectivity requirements, demand for base stations is also growing. A base station is a fixed-location wireless communication station, with one or more antennas, that receives and transmits signals in a cellular network to phones and other devices.
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 long term evolution (LTE), time division-LTE (TD-LTE) and 5G New Radio (5G-NR) networks.
In addition to the traditional macro network, which is used for wide area coverage, the rollout of smaller base station formats also are being pursued. These formats include picocell, small cell and carrier-grade Wi-Fi solutions to support growing data requirements in urban areas. These products will increase 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 rollout 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 data rates but can be used to increase the flexibility of the backhaul deployment.
