Amplifier and antenna gain may sound the same, and both may be expressed in decibels, but they actually are measures of two different things. In an amplifier, gain is simply the ratio of the output divided by the input. Gain has no units as it is a ratio. However, amplifier gain is often expressed in […]

How to extend, boost and repeat Wi-Fi signals
Since the U.S. Federal Communications Commission (FCC) limits Wi-Fi transmitter power, it’s often necessary to increase the range of Wi-Fi signals using some signal boosting/extending technology. But transmit power is only half of the equation. Wi-Fi connections are always bidirectional and symmetrical. When working to extend Wi-Fi signals, the bidirectional nature of the connection is […]
The basics of Wi-Fi security and encryption
Wi-Fi security has significantly improved over the years from initially being more aspirational than real until today, where Wi-Fi 6 security is considered to be on a par with the security of 5G telephony. This FAQ will answer several questions related to Wi-Fi security and encryption: What’s the difference between WEP, WPA, WPA2, and WPA3? […]
RFICs provide beamforming and frequency conversion
A series of mmWave beamformers and up/down converters from pSemi provide the RF front end for repeaters, small cells, and indoor base stations. Beamforming at mmWave frequencies continues to take on importance, targeting signals at mobile devices. A series of beamforming and up/down converters from pSemi cover the n257, n258 and n260 bands support eight…
What to consider when selecting a Wi-Fi antenna
Antennas are a critical part of the link budget in all wireless communications applications, including Wi-Fi. In addition to the numerous antenna performance and link budget issues in wireless communications, there are general architectural challenges. The architectural options are the focus of this FAQ, including; long-distance versus local Wi-Fi and the use of directional vs. […]
Antenna markings help standardize radiation patterns, boost synchronicity of azimuth gain readings
Tallysman Wireless announced a North orientation mark to its TW3000 family of Accutenna precision antennas and its TW5000 family of smart antennas. This new feature will allow our customers to align their antennas, standardize radiation patterns, and increase the synchronicity of their azimuth gain readings across multiple devices. The new North mark orientation design has […]
Is 5G/Wi-Fi convergence coming?
Smooth transitions from 5G to Wi-Fi networks as you move seems obvious, but technology differences keep convergence from solidifying.
