Modern airports are bustling centers of communications, with an increasing number of people using mobile devices on the go and expecting anytime, anywhere connectivity. Further taxing wireless networks are airport facilities workers and public safety activities. What makes that communication so challenging is the airport’s large coverage area and high-capacity requirements. Such issues make providing adequate coverage and capacity for all users an elusive goal. That’s exactly the challenge YYC Calgary International Airport faced when it began building its new international terminal. The airport had virtually no commercial or public safety coverage from the macro, and as a result, the new international terminal faced both coverage and capacity issues.
In this work, a high-gain broadband printed Yagi directional antenna for applications in ISM bands (686 and 915 MHz) is presented. The proposed antenna was designed to be implemented in a wireless system, devoted to water and wastewater level and underground flow measurements.
This paper describes the effects of various quality variables on microwave antenna performance, and provides insight into the long-term consequences of using a low-cost/ poor-quality antenna. It demonstrates the effect of operators’ preference for low-cost antennas without considering the total cost of ownership, as well as possible ill effects on their quality of service.
This application note presents a new predictive capability for simulating massive MIMO antennas and beamforming in dense urban propagation environments. Wireless InSite MIMO predicts the complex channel matrix for mobile devices within a small cell. Beamforming techniques are used to display the actual physical beams and evaluate signal power and interference, including pilot contamination distortion.
Narda Safety Test Solutions presents the AMS-8061 Area Monitor designed for monitoring electromagnetic fields from 100 kHz to 6 GHz in up to 20 freely definable frequency bands. Capable of independent operation, this monitor functions on the power of solar cells and rechargeable batteries, which enables uninterrupted measurements over an unlimited period of time. Results are stored internally and can be read out locally via Ethernet, USB, or RS 232, transferred to an SD card, or accessed remotely over a cell phone link.
Skyworks has expanded its tuning product portfolio with the addition of several new high performance solutions for antenna tuning, impedance tuning, and band switching applications. These antenna aperture tuner switches are designed for enabling higher data throughput and smaller footprints, minimizing dropped calls, and improving the consumer experience.
Teledyne Labtech, a business unit of Teledyne Microwave Solutions (TMS), is one of the few companies in the world who can offer large format PCB for use in RF/microwave applications. Their products and PCBs can be found in a large range of products ranging from antennas for large phased array radar, to components used in the world's most sophisticated fighter aircraft. Their continued investment has expanded their capabilities to enable Teledyne Labtech to offer a large range of non-standard PCBs. The auto-clave vacuum oven capability allows Teledyne Labtech to manufacture large format multilayer PCBs.
Highly mobile shelters deployed in harsh environments rely on the high connectivity, security, and other benefits that an RF-over-Fiber system has to offer. HUBER+SUHNER provides fiber optic cables that allow for shelters to be positioned far away from the antennas, yet still ensure that antenna links and the shelter are secure. These fiber optic cables are also able to reduce the cable footprint of the application, making the solution lighter in weight, higher in mobility, and dramatically speed up and simplify installation and maintenance.
The Re-Entry Vehicle Toolbox from the IDS Computational Electromagnetic Laboratory has been integrated into the ADF-EMS v5.1 system. The software aims to provide a set of capabilities for the analysis and optimization of RF links between a re-entry vehicle and ground or satellite relay stations.
Urban multipath can be extremely complex, particularly with devices in motion. Remcom offers a unique ray tracing capability for simulating these effects and predicting MIMO system performance.
HUBER+SUHNER presents the SENCITY® Shield antenna platform especially designed to support all communication bands including LTE, 2G/3G cellular, 2.4/5 GHz WiFi, 3.5 GHz, and 4.9 GHz public safety. The SENCITY® Shield antenna features high RF power handling, small form factors, low visibility, and uniform signal distribution.
