Mobile Use at Democratic National Convention Foreshadows Nationwide Demand

 

In the weeks leading up to the Democratic National Convention in early September, service providers in Charlotte, NC prepared for the arrival of the estimated 35,000 attendees by enabling Wi-Fi hotspots for free access and adding additional cell sites, portable COWs (cells on wheels) and extra antennas throughout the area. Time Warner Cable enabled 120 Wi-Fi access points … [Read more...]

New Multi-Antenna Technology Can Help Keep Up with Increasing Data Traffic

 

Researchers from Rice University, Yale University and Bell Labs have successfully demonstrated a new technology that will enable mobile network operators to increase capacity without adding spectrum by allowing cell towers to simultaneously beam signals to more than a dozen customers on the same frequency. Known as Argos, the new multi-antenna technology will assist wireless … [Read more...]

World’s Smallest Antenna Increases Wi-Fi Speed By 200 Times

 

Researchers from A*STAR’s Institute of Microelectronics (IME) in Singapore have successfully developed the world’s smallest high performance cavity-backed slot (CBS) antenna. Operating at an extremely high frequency of 135 GHz, the silicon-based antenna exhibited signal transmissions 30 times stronger than on-chip antennas operating at the same frequency. The antenna measures … [Read more...]

AT&T Disables Tower Frequencies after Emergency Communications Disrupted

 

ATT temporarily disabled a frequency emitted by 16 towers in Oakland Calif., Tuesday, Aug. 21, after the signals interfered with emergency responder radio communications. The towers caused radio failures in police cars and fire trucks when they were within a quarter to half mile radius, David Cruise, Oakland's public safety systems adviser, said. FCC confirmed the … [Read more...]

CISPR 16-1-5 specifies the requirements for calibration test sites used to perform antenna calibrations, as well as the test antenna characteristics, calibration site verification procedure and site compliance criteria. Measurement instrumentation specifications are given in CISPR 16-1-1 and CISPR 16-1-4. Further information and background on uncertainties in general is given … [Read more...]

Researchers Develop Holographic Antenna Prototype

 

EU-funded researchers are investigating the development of prototype holographic antennas in the microwave frequency range of the electromagnetic spectrum for use in a variety of applications as part of the ALOHA Torino-Sydney project. According to the abstract, the project aims to “investigate and experimentally characterize some prototypes of devices supporting the … [Read more...]

EMC Antenna Parameters and Their Relationships

 

*originally published in June 1997. Introduction The basics of the EMC profession often get buried under the day-to-day effort of continuous measurement and the volume of test and reporting paperwork. The fundamental parameter of the most common of technical tools, the EMC antenna, is used over and over without thought as to its actual meaning. This parameter is the antenna … [Read more...]
