be an answer for the health care solutions will definitely help the living easier. In this setup we use a wireless technology with the help of ZigBee and AvR microcontroller. With the help of this system configuration, the diagnostic details of a person sitting in any place could reach continuously to his

among the efficiencies of different physical layers, this paper illustrates the design and implementation of lowpower and high-performance nodes in WSN from the perspectives of 2.4G physical layer baseband spread spectrum and O-QPSK modulation demodulation, proposes a cascade de-spreading method

-conversion receivers and transmitters and summarizes some of the key problems in their implementations. Solutions to these problems arise not only from more appropriate circuit design but also from exploiting system characteristics, such as the modulation format in the system. Baseband digital signal processing must

In 1993, IBM first began offering its ASIC product line to non-IBM companies. In March of this year, DataQuest announced that IBM had surpassed all competitors to capture the lead in ASIC worldwide market share. How did we accomplish this? World-class hardware certainly played a major role, but it is not the complete story. What we’ve learned in the seven years that we’ve offered this product to the merchant marketplace is this: our first piece of business with a new customer is most often won by what we say our hardware can do. However, in most cases, customers tell us that they keep returning because of the unique advantages of IBM’s design-automation (DA) tools. Many of IBM’s proprietary DA tools have been discussed in public forums, but the focus has been on implementation process steps—not on the benefits our customers derive by

patient. ECG Acquisition system is designed and the signals are plotted in LabVIEW. The Signal from ECG acquisition module is given to Zigbee module. The transmitted signals are then received by Zigbee Transceiver. TTL output from the receiver Zigbee module is converted to RS232 using MAX232 level

to the receiver. The receiver according to the control signals controls the speed of the DC motor provided by Pulse Width Modulation (PWM).The control signals are transmitted using RF wireless module Zigbee. Hence forth the speed of the DC Motor can be controlled wirelessly through a control room which makes

In this paper, we analyze the Multiband orthogonal frequency-division multiplexing (OFDM) system for high-rate wireless personal area networks (WPANs) based on ultra-wideband (UWB) transmission and with the help of Zigbee transceiver. We also propose system performance through the application

network as it implements a wireless link in which the waves can penetrate a limited number of walls. In such cases a wireless link is preferred. In proposed system ZigBee module is used to establish wireless link between transmitter and receiver. The proposed advanced control room can be addressed as a
