Is More Antenna Gain Better? The Logarithmic dB Scale Antenna engineers use a logarithmic scale to express this apparent 2x (times two) mirror power doubling as “+3 dBi”. It still means “doubling”. Here are some other examples of ratios or multipliers on the engineering dBi gain log sca...
The dBd value is compared with a dipole antenna, which itself has 2.14 dB gain over isotropic radiator. With this logic, antenna having gain of 7dBd will have gain of 9.14 in units of dBi. In other words both 7dBd and 9.14dBi with respect to antenna gain are equivalent. ...
Decibel (dB) definition Decibel (Symbol: dB) is a logarithmic unit that indicates ratio or gain. Decibel is used to indicate the level of acoustic waves and electronic signals. The logarithmic scale can describe very big or very small numbers with shorter notation. ...
In this commentary, we suggest continuing their effort to understand what is distinctive about Chinese multinational enterprises (CMNEs). We look for underlying explanations that are analytically useful and potentially generalizable, unlike a firm's nationality, which is a catch-all variable with no ...

Units of Antenna Gain While field strength at any location is independent of antenna gain, received voltage at the receiver is not. Therefore, let us first consider antenna gain. Gain may be expressed as either a power multiplier or in dB. Antenna gain stated in dB is referenced ...
Azure Cosmos DB supports PostgreSQL, MongoDB, and Apache Cassandra, is fully managed, auto-updates, and auto-scales.The future of SQL The future of SQL is in the cloud, which is why many organizations are now opting for cloud databases over traditional, on-premises solutions. A cloud data...
Uber:Uber utilizes big data to gain better insights and provide better service to its users. With its huge database of drivers, it can suggest to users the most suitable one. Uber charges customers based on the time it takes to get to their destination. This prediction is helped by variou...
This is an intentional attack on a system with the aim of finding security vulnerabilities, through which an attacker can gain access to the entire system that includes the database. If a weakness is found, then the immediate action is to fix and mitigate any threat such a vulnerability could...
applications, such as self-service analytics, can be game changers for nearly any department, but IT teams must put the time and effort into education, familiarization, and training; this is a long-term investment that produces significant organizational changes in order to gain insights and ...
