Answer 2

Access point ap

Question 3

And antennas – – – – – – – – – – describes the relative strength over a three-dimensional area I’m all electromagnetic energy in the antenna sent or received

Answer 3

Radiation pattern

Question 4

This in China issues wireless St. Louis along a single direction this type is used when the source needs to communicate with One Direction is in a point to point link or in a specific area

Answer 4

Directional antenna or unite directional John

Question 5

This antenna issues and receives wireless signal with someone equal strength and clarity in all directions

Answer 5

Omni directional antenna

Question 6

You can determine the gain or loss of an access point attached to an external seller by considering initial power output of the HP, signal loss along the antenna cable, and signal gain from the antenna itself and it is a theoretical ratio used to measure and Teleperformance this overall calculation is referred to as – – – –

Answer 6

E IRP effective iso tropic radiant power

Question 12

After the signal is transmitting the father of moves away from the transmission source the more it weakens this is called – – – – –

Answer 12

Attenuation

Question 13

As a single runs into various obstacles generally will gradually fade which causes the strength of a signal that reaches the receiver to be lower than that transmit signals or strength this is known as

Answer 13

Fading 

Question 14

Electromagnetic waves at the atmosphere can interfere with wireless communication similar to have EMI affects wire transmissions because wireless signals cannot depend on a conduit or shielding to protect them from EMI then we’ll vulnerable to noise then wire transmissions are this is known as 

Answer 14

Interference

Question 15

The proportion of noise to the strength of a signal is called

Answer 15

Signal to noise ratio
