QoS measurement of Zigbee home automation network using various modulation schemes
FREE-DOWNLOAD G Kaur… – International Journal of Engineering Science, 2011 -Increased demands on implementation of wireless sensor networks in automation praxis resulted in relatively new wireless standard – Zigbee. The research 802.15.4 standard specifies the multiple PHYs for 868, 915 and 2400 MHz three frequency bands. In this paper we
Enabling Coexistence of Heterogeneous Wireless Systems: Case for ZigBee and WiFi
FREE-DOWNLOAD X Zhang… – Proc. of ACM MobiHoc, 2011 ABSTRACT The ISM spectrum is becoming increasingly populated by emerging wireless networks. Spectrum sharing among the same network of devices can be arbitrated by MAC proto- cols (eg, CSMA), but the coexistence between heteroge- neous networks remains
Low-Power Quadrature Receivers for ZigBee (research 802.15. 4) Applications
FREE-DOWNLOAD tM Tedeschi, A Liscidini… – Solid-State Circuits, research …, 2010 – Abstract—Two very compact and low power quadrature re- ceivers for ZigBee applications are presented. Area and power savings are obtained through both current reuse and oscillator tank sharing between the I and Q paths. Since this choice can cause I and Q amplitude/phase
