HetNet Nodes Clause Samples

HetNet Nodes. Distinguished broadly by their transmit power level and backhaul are the small cell nodes in HetNets [36]. The underlying macro base station providing full coverage for such small cells will operate on approximately 5 - 40 W transmit power. Local to any hotspots, the small cells provide a reliable service in addition to alleviating macro coverage holes. High degree of flexibility is offered by the low power nodes as they can have access technologies different to that of the macro base station (Cellular, WLAN, etc) [37] [38]. Costs associated with small cells are also significantly lower that macro base stations. Outdoor low power nodes operating between 250 mW - 2 W of transmit powers do not need air conditioning units for their power amplifiers, proving to be even more cost effective. Next I present the low power base stations considered as transmission nodes in HetNets [34] as depicted in Figure (2.3) and discuss some of their key features:
