Femtocell access points are inexpensive, plug and play home base stations designed to extend radio coverage and increase capacity within indoor environments. Their inherent uncoordinated and overlaid deployment however, means existing radio resource management (RRM) techniques are often ineffectual. Recent advances in dynamic RRM have emphasised the need(More)
—Femtocells are primarily used to extend high-quality radio coverage in indoor environments. Dense femtocell access point (FAP) deployment however, can lead to severe interference on femtocell user equipment (FUE) from neighbouring FAP, when they operate on the same channel. The problem is compounded as FAP are deployed in an uncoordinated manner by the(More)

Base station (BS) sleeping in cellular networks has emerged as a promising solution for more energy efficient communications, concomitant with lowering the network carbon footprint. Switching off specific BS entirely however, can lead to coverage holes and severe performance degradation. To avoid coverage holes, the transmit power of neighbouring BS must be(More)
Applying a Base Station (BS) sleep approach during low traffic periods has recently been advocated as a strategy for reducing energy consumption in cellular networks. The complete switching off of certain BS however, can lead to coverage holes and severe performance degradation in terms of off-cell user throughput, greater transmit power dissipation in both(More)
THE OXFORD/EDINBURGH HYBRID ARM Microprocessors are increasingly used in prosthetic applications. The flexibility they provide allows new functions to be added easily, and fitting and maintenance can be simplified [1,2,3]. Prosthetic controllers are available that can be adapted to different needs through field programming, allowing the prosthetist to try(More)

—Femtocells are low-power nodes which aim to extend high data-rate wireless services in indoor environments, where typically the radio signal quality is poor in conventional cellular systems. While low power operation allows more frequent spectrum reuse and significant improvement in network capacity, it also suffers from frequent handoffs between the macro(More)
