Capacity of cellular networks deployed in TV White Space

摘要: This paper investigates how suitable TV White Space (TVWS) is for use by cellular networks. Unlike in licensed bands, transmit power TVWS limited and considerable interference from towers exists. suggests that evaluating only terms of available bandwidth can be misleading, since performance wireless networks likely lower than the same amount dedicated spectrum. We quantify at example Germany, using European methodology developed CEPT ECC SE 43. In second step, we determine a network operating calibrated multi-cell multi-user system level simulation tool. way also consider between users, which previous studies has not been investigated detail. Not all locally channels are equally useful. thus compare different channel selection algorithms operator could apply to select set channels. found while spectrum usage theory quite high, its actual utility strongly depends on method requirements it based on. Due high towers, frequency re-use one (like LTE) have difficulties finding allow good cell edge. The inner part however considerably benefit TVWS. indicates primarily traffic offloading spotty coverage rather building large contiguous
