The performance gain of a antenna is being stated in dBi. As already stated, commercial 2.4GHz based WiFi components work with a transmission power of 50-100mW. The transmission power of a WiFi component can also be indicated with this unit. The unit dBm is an absolute power rating in relation to one milliwatt. The individual dB values are being added or subtracted to calculate the overall performance of a coherent system. The damping (loss of performance) of atenna cables or plug connections is being stated in dB. WiFi components are working with a relatively low transmission power and are therefore not stated in watt, but in the next smaller unit, millitwatt.ĭecibel is a measuring value for simplified calculation of perfomance, damping and increase of connected components and systems based on a logarithm. Commercial 2.4GHz WiFi components work with a transmission power of 50-100mW. With this unit the transmission power of active WiFi components (WiFi router, WiFi access points, USB adapter) is being stated. In general you can say straight away: The higher the indicated value (no matter whether it’s dbi, dBm or mW) the higher the transmission power of the particular component. In the fields of radio technology (therefore also with WiFi components) are different measured quantities which are served for power rating (transmission power / increasing performance) of individual components. What these indications mean and how to understand them is explained in the following text: In our offers you’ll often find the indications of dBi, dBm, mW or watt.
