What matters the most to the future of Wi-Fi technologies? Major concerns include high data rate, high capacity, and a good range of coverage. This white paper covers these areas of interest, the problems involved in implementing Wi-Fi growth requirements, and possible solutions.
It can be hard to fully account for thermal management and affected parameters in wireless access points or customer premises equipment prior to FCC certification. This article is the first in a series that looks at the design challenges for Wi-Fi front end designs. Part 2 will cover coexistence and interference.
The population of adults 85 and older in the U.S. will roughly triple between 2015 and 2060, making it the fastest-growing age group over this time period. This has become a major concern for families taking care of seniors who will be living on their own. Qorvo’s Senior Lifestyle System has been tested and used for the last 15 years in assisted living communities in Europe to help seniors live more independently. Within a few weeks, this system learns the routine day-to-day activities of the senior resident, provides intelligent status updates in a dashboard app, and sends alerts to designated caregivers if something unexpected happens.
By monitoring behavior patterns through unobtrusive wireless sensors located around the home, the system is able to detect changes in behavior that may cause concern, and then alerts family members or caregivers via messages.
Advancements in Gallium Nitride technologies are leading to amplifier operation at higher powers, supply voltages, and frequencies. The whitepaper includes load-pull measurements, thermal considerations, and EM simulations of the input/output matching networks.
The smart home revolution has taken a lot longer to get up and running due to the disagreements over what protocols and platforms should be used in the base technologies, as well as the poor choices in consumer words like “smart home” and “IoT.”
Solid state amplifiers can be constructed through the use of MMIC amplifiers to reach output powers and performance levels that have only been achievable by traveling wave tube amplifiers (TWTAs). This white paper demonstrates building a 120 Watt power amplifier operating from 27 to 31 GHz.
Carrier aggregation (CA) enables mobile network operators worldwide to provide faster data, and allows mobile devices to communicate on multiple LTE bands simultaneously. This, however, creates the challenge of avoiding interference between the bands while keeping up good reception and battery life. Multiplexers are an excellent solution for CA combinations that use closely spaced bands since they provide isolation between and within bands, while allowing them to connect to the antenna at the same time. This white paper discusses the challenges of carrier aggregation, and the important benefits of using multiplexer solutions to solve them.
There are robust plans for rapid 5G deployment, especially in regions where wide bandwidth provided by new 5G bands are able to produce higher data rates for consumers. This download offers five points to reaching this goal and predicts what to expect from 5G technologies in the future.
The CATV industry is looking to set new standards for the next generation of cable ecosystems, including the Full Duplex (FDX) DOCSIS 3.1, which promises to deliver 10 Gbps data rates upstream and downstream on existing hybrid fiber-coaxial (HFC) systems. Achieving FDX will require highly linear devices enabled for digital predistortion (DPD) — including 75-ohm CATV switches. This article explores how DPD works in CATV optical nodes, as well as some considerations for selecting the right switch for each application.
