BLE based Accessory-Smartphone communication (WBANs/WPANs), used for health-care, infotainment and many other applications, usually operate in dynamic environment (varying number of sensors, wireless conditions, etc.). These devices are typically configured in connection-oriented hub-and-spoke model with the Master controller. With an end-objective of optimizing the capacity of BLE (Bluetooth Low Energy) centric systems, we share analytical models, experimental […]
Read moreThis revision specifies technical corrections and clarifications to IEEE Std 802.11 for wireless localarea networks (WLANS) as well as enhancements to the existing medium access control (MAC) and physical layer (PHY) functions. TBD: It also incorporates Amendments 1 and 2 published in 2012.
Read moreThis paper proposes an efficient data compression technique dedicated to implantable intra-cortical neural recording devices. The proposed technique benefits from processing neural signals in the Discrete Haar Wavelet Transform space, a new spike extraction approach, and a novel data framing scheme to telemeter the recorded neural information to the outside world. Based on the proposed […]
Read moreFor real-time image/video transmission in implant body area networks, we have developed an in-bodytransceiver at around 30 MHz. The transceiver employs impulse radio (IR) technology with multi-pulse position modulation (MPPM) scheme. The transmit antenna was realized in a dimension of 1 × 2 cm by forming the radiation elements on a flexible magnetic sheet. Experimental results in a […]
Read moreAn experimental characterization of the off-body propagation channel for the ultrawideband (UWB) band from 3.1 GHz to 8 GHz for body area networks (BAN) is presented in this letter. The channel is evaluated in terms of path loss (PL) and Root Mean Square (RMS) delay spread. Channel statistics from measurements carried out considering subjects of different gender in standing still […]
