What is the relationship between EIRP and antenna gain?

Equivalent isotropic radiated power, EIRP, is the total radiated power from a transmitter antenna times the numerical directivity of the antenna in the direction of the receiver, or the power delivered to the antenna times the antenna numerical gain.

How do you calculate EIRP on antenna?

Calculation: E.I.R.P. = 16 dBm + 8 dBi – 3,2 dB – 1 dB = 19,8 dBm (i.e. the power level meets the requirements – less than 20 dBm).

What is EIRP used for?

Most often conveyed as either decibels (dB), or decibels over isotropic (dBi), EIRP is used to gauge the maximum possible radiation from an RF system, either for standards purposes or for specification. With an isotropic radiator, the radiation is emitted as a point source with a spherical radiation pattern.

What is EIRP in telecom?

Equivalent Isotropically Radiated Power (EIRP) is the product of transmitter power and the antenna gain in a given direction relative to an isotropic antenna of a radio transmitter. Normally the EIRP is given in dBi, or decibels over isotropic.

How does a high gain antenna work?

When transmitting, a high-gain antenna allows more of the transmitted power to be sent in the direction of the receiver, increasing the received signal strength. When receiving, a high gain antenna captures more of the signal, again increasing signal strength.

What is calculate EIRP limit?

Maximum Effective Isotropic Radiated Power (EIRP) is 36 dBm (4 watt). The maximum EIRP allowed is 53 dBm (30 dBm plus 23 dBi of antenna gain). In the 2.4 GHz band you can increase the antenna gain to get an EIRP above 36 dBm but for every 3dBi increase of antenna gain you must reduce the transmit power by 1 dBm.

What is difference between ERP and EIRP?

EIRP is the Effective isotropic radiated power is the total power radiated by a hypothetical isotropic antenna in a single direction. ERP is Effective Radiated Power is the total power radiated by an actual antenna relative to a half-wave dipole rather than a theoretical isotropic antenna.

What is power gain Electronics?

From Wikipedia, the free encyclopedia. The power gain of an electrical network is the ratio of an output power to an input power. Unlike other signal gains, such as voltage and current gain, “power gain” may be ambiguous as the meaning of terms “input power” and “output power” is not always clear.

How does high-gain antenna work?
