This paper presents a software prototype of wireless network for the Internet Things (IoT) based on DECT (Digital Enhanced Cordless Telecommunication) standard. It proposes an architecture encapsulating commands from most common IoT protocol, MQTT (Message Queuing Telemetry Transport), into SIP (Session Initiation Protocol) packets. A module is created to embed MQTT-SN (MQTT Sensor Networks) pa...

Recently there has been a considerable effort devoted to intelligent joint speech coding and iorward error correction (FEC) coding [I] as well as to equal [2] and un-equal protection coded modulation [3]. In reference [4] Hagenauer introduced an intelligent framework for considering source significance-, channel stateand decoder reliability-information in order to achieve the best possible perf...

BACKGROUND The use of cellular and cordless telephones has increased dramatically during the last decade. There is concern of health problems such as malignant diseases due to microwave exposure during the use of these devices. The brain is the main target organ. METHODS Since the second part of the 1990's we have performed six case-control studies on this topic encompassing use of both cellu...

This paper presents a telephony solution for Local Multi-point Distribution Service (LMDS) using technology for Personal Communications Services (PCS). An actual system based on Digital Enhanced Cordless Telecommunications (DECT) has been implemented. The system architecture of the DECT-based LMDS telephony system is discussed. Performance measurement results show that a DECT-based system does ...

OBJECTIVE On April 25, 2012, the first laparoscopic cordless ultrasonic device (Sonicision, Covidien, Mansfield, Massachusetts) was used in a clinical setting. We describe our initial experience. METHODS The cordless device is assembled with a reusable battery and generator on a base hand-piece. It has a minimum and maximum power setting controlled by a single trigger for both coagulation and...

Digital mobile communications comes to company sites. No cabling is required and the employees can be reached at any time at any place. However, planning of wireless digital networks is quite different from planning traditional wire-based systems. Small, local radio transmitters (senders) have to be installed to provide the wireless devices with signals. The specifics of radio wave propagation ...

To investigate the difficulties in communication, socialization abilities, and emotion perception deficits in individuals with autism spectrum disorders (ASD), we propose the project SARA. Its main goal is to assess how abstracted emotional facial expressions influence the categorization of the emotions by children and adolescents with highfunctioning ASD. This paper focuses on the first pilot ...

background: various strategies such as teaching self care to hemodialysis patients have been employed to increase the level of their hope. this study aimed at examining the effects of a telephone follow-up program on the level of hope in a self care education program. methods: in this single-blind randomized controlled clinical trial, 75 hemodialysis patients, selected by convenient sampling, w...
