In mobile networks, backhaul is needed to connect the small cells to the core network, internet and other services.
Mobile operators consider this more challenging than macrocell backhaul because small cells are typically in hard-to-reach, near-street-level locations rather than in more open, above-rooftop locations and carrier grade connectivity must be provided at much lower cost per bit. Small cell backhaul planning consists in selecting the appropriate technology to connect small cells to the backhaul (fiber, microwave link, nLOS/NLOs) and setting the connection parameters.
Atoll takes into account backhaul accessibility in its site selection process for small cells to make sure that selected sites not only deliver the desired coverage and capacity but can also easily be connected to the backhaul. Atoll Microwave provides wireless operators with comprehensive link planning features, including non or near line of sight (NLOS/nLOS) conditions that can occur with small cell sites.
