  • Low RF Power Harvesting Circuit for Wireless Sensor Nodes in Industrial Plants
    Low RF Power Harvesting Circuit for Wireless Sensor Nodes In Industrial Plants Issam Chaour∗† Olfa Kanoun∗ and Ahmed Fakhfakh† ∗Chair for Measurement and Sensor Technology, Technische Universitat¨ Chemnitz , GERMANY †National Engineering School of Sfax, University of Sfax, Sfax, TUNISIA Email: [email protected] Abstract—Techniques and methods of energy harvesting are developed to recuperate energy coming from the ambiance to be transmitted to electronic systems. Energy should be useful in specific applications, to generate a certain voltage level and make capable of delivering a recommended Power to the load. So, the main challenge for energy harvesting is to obtain a significant amount of power efficiently from the environment. This paper describes an overview of power transfer systems and methods of charging low power sensors in industrial plants using harvested RF signals. It introduces a scheme investigation of the RF harvester consisting of receiver antenna and a rectifier circuit to convert the RF signal to DC voltage. Low power consumption Fig. 1.

Assumption is that everyone is familiar with testing equipment so test setup and equipment settings will not covered. The approval process for these types of equipment was previously called Type Acceptance or Notification. Now all methods of equipment approval are called Certification. This information generally applies to all Radio Service Rules for scopes B1 through B4. 2 General Information Understanding how FCC rules for licensed equipment are written and how FCC operates The FCC rules are Title 47 of the Code of Federal Regulations Part 2 of the FCC Rules covers general regulations & Filing procedures which apply to all other rule parts Technical standards for licensed equipment are found in the various radio service rule parts (e.g. Part 22, Part 24, Part 25, Part 80, and Part 90, etc.) All material covered in this training is either in these rules or based on these rules October, 2005 ¾TCB Workshop 3 There are about 15 different radio service rule Parts which require equipment to be authorized before an operators license can be obtained.

  • Range Calculation for 300Mhz to 1000Mhz Communication Systems
    APPLICATION NOTE Range Calculation for 300MHz to 1000MHz Communication Systems RANGE CALCULATION Description For restricted-power UHF* communication systems, as defined in FCC Rules and Regula- tions Title 47 Part 15 Subpart C “intentional radiators*”, communication range capability is a topic which generates much interest. Although determined by several factors, communica- tion range is quantified by a surprisingly simple equation developed in 1946 by H.T. Friis of Denmark. This paper begins by introducing the Friis Transmission Equation and examining the terms comprising it. Then, real-world-environment factors which influence RF commu- nication range and how they affect a “Link Budget*” are investigated. Following that, some methods for optimizing RF-link range are given. Range-calculation spreadsheets, including the special case of RKE, are presented. Finally, information concerning FCC rules govern- ing “intentional radiators”, FCC-established radiation limits, and similar reference material is provided. Section 7. “Appendix” on page 13 includes definitions (words are marked with an asterisk *) and formulas. Note: “For additional information, two excel spreadsheets, RKE Range Calculation (MF).xls and Generic Range Calculation.xls, have been attached to this PDF. To open the attachments, in the Attachments panel, select the attachment, and then click Open or choose Open Attachment from the Options menu. For addi- tional information on attachments, please refer to Adobe Acrobat Help menu“ 9144C-RKE-07/15 1. The Friis Transmission Equation For anyone using a radio to communicate across some distance, whatever the type of communication, range capability is inevitably a primary concern. Whether it is a cell-phone user concerned about dropped calls, kids playing with their walkie- talkies, a HAM radio operator with VHF/UHF equipment providing emergency communications during a natural disaster, or a driver opening a garage door from their car in the pouring rain, an expectation for reliable communication always exists.

  • Radiofrequency Radiation Measurements Public Wifi
    Radiofrequency Radiation Measurements for Public Wi-Fi Installations in Hong Kong Office of the Communications Authority 25 May 2017 Introduction The Office of the Communications Authority (formerly Office of the Telecommunications Authority, hereinafter collectively referred to as “OFCA”) has since 2007 regularly conducted territory-wide survey of the non-ionizing radiation (“NIR) levels in the public areas due to public Wi-Fi access points (“APs”). The survey aims to gauge the abovementioned NIR levels and ensure that the NIR generated from public Wi-Fi APs does not cause exposure to the public in excess of the exposure limit recommended by the International Commission on Non-Ionizing Radiation Protection (“ICNIRP”) which is adopted by the Communications Authority (“CA”), in consultation with the Department of Health, for the protection of the public against the NIR hazards from radio transmitting equipment. 2. This report1 presents the results of the survey conducted between November 2016 and February 2017. It is the fourth report in the series (previous ones were published in 2007, 2011 and 2014 respectively). As with the previous surveys, the latest survey results indicated that the NIR levels at the measurement locations with public Wi-Fi APs installed were well below the exposure limit recommended by the ICNIRP (the “ICNIRP limit”), ranging from less than 0.1% to 0.6% of the limit. The results tally with the finding of the World Health Organization (“WHO”) that exposure levels due to Wi-Fi are generally very low. According to the WHO, there is no convincing scientific evidence that the weak radiofrequency signals from wireless networks (including Wi-Fi) would cause adverse health effects.
