Basic : AP and Client connectivity link

Hello,

This may be a very basic question for all of you but Iam confused.

Suppose we have an AP which has a range of say 500m. So i assume 500m around the AP will be the coverage area.
I understand that throughput will decrease as we move further from the AP.

Now suppose we have a client having a range of say 100 m only (genrally clients r not as powerful as AP rite) and this client is situated at the 400m range from the AP.

Will the AP and the client get connected?
Is it that the AP packets will travel and be received by the client since the client lies within the AP range but the client packets will not reach the AP? so there wont be a connection? Iam confused!!


I have also added a diagram to explan my query. please throw some light.

The Client to AP relationship is a two-way street.
Both devices must be able to "hear" each other in order to
establish a connection. So to answer your question, if the client
has a range of only 100m, it will not be able to connect to the Access Point
beyond that distance.

Thanks for your post.

So do you mean that a far away client radio also shld be as powerful and boosted up as an AP?

Will not a client (having 100m range) get connected even at 400m from AP but with a lesser throughput than a client connected at 100m from AP?

or is it that only the client at 100m range will get connected?

it just doesn't work that way.

imagine that you have a graph showing the range of the wonderwhiz router when used with wonderwhiz notebook computers. a circle 100 feet across.

now use use the same wonderwhiz router with the new wonderwhiz mark II notebook, with 3 dB ( twice the power ) better antennas.

that circle is now 140 feet across ( 1.4, the square root of 2, times the original 100 feet )

use the same, unchanged router with 6 dB ( 4 times the power ) antennas, you double the range to 200 feet, and you have not changed the router one bit.

the range circle describes the range of the router when connected to clients with a certain antenna. change the antenna on either end, the range changes. the range circle is dependent on conditions on both ends.
