Questions about Wi-Fi adapters, amplifiers, and antennae

Hi:

I have this network adapter -- http://www.newegg.com/Product/Product.aspx?Item=N82E16833122382 -- WG311NAR

I'm looking for a way to strengthen my Wi-Fi reception regardless of the access point I'm using.

I need an antenna system with it's own power supply to strengthen the Wi-Fi signal. Current the signal strength registers at only 20%. I want to strengthen the reception to 100% -- or as strong as possible -- without increasing the transmission strength.

Ideally, I would like the transmission strength to be the minimum required to access the internet but with the reception strength being the maximum possible. I don't mind if the my internet speed is slow due to weak transmission.

Where I live, there is a coffee shop that allows free use of their open wireless access point. So if the signal being received by my network adapter is intense enough, I'd by able to access the net via the coffee shop from my residence.

A. Is there a way to amplify the received wireless radio signal after it has been picked by an antenna and then feed the strengthened signal into the WG311NAR adapter? If so, then it wouldn't matter whether or not the antenna is directional. Are there any devices that will do this? I've heard of wireless repeaters that will boost and then re-transmit radio signals but I don't want this because they will also amplify the radio signal my adapter transmits.

B. If such a device does not exist, then I would like to purchase a wireless adapter with the following characteristics:

1. The strength of the transmitted wireless carrier signal is the minimum required in order to access the net

2. The amplitude of the modulation signal about to be imposed on the wireless carrier signal about to be transmitted should be the minimum required in order to access the net

3. It doesn't matter to me whether the adapter uses one antenna or two antennae. In either case, however, reception should involve the use of an omni-directional antenna that picks up signals in all directions.

4. It doesn't matter to me whether the antenna[e] is [are] external or internal

5. It doesn't matter to me whether the wireless adapter is internal [e.g. PCI] or external [e.g. USB]

6. The antenna-gain or sensitivity does not matter to me

7. The strength of the received carrier signal does not matter to me

8. Amplification of the received wireless radio signal should be done after de-modulation. After de-modulation -- the resulting electric signal should amplified as much as physically-possible without damaging the wireless adapter. This will provide a relatively efficient wireless internet access while consuming relatively little power and transmitting a relatively weak radio signal. This process will also generated relatively little radio-frequency interference.

If the hypothetical device in A does exist, from where can I purchase it?

If the hypothetical device in A does not exist, which wireless adapter should I buy?


Thanks a bunch,

We can't really help you because you're leeching from someone else, if it was a home network it would be different.
