Difference between the Kasens g5000 and g 9000? vs Alfa USB dongles?

[DJW]

I have a kasens g5000 high power wifi usb adapter with a RTL8187L chipset that I like a lot. But been thinking of getting another USB wifi dongle and I see a kasens g9000 high power wifi USB adapter with I think also has a RTL8187L chipset. The G5000 is 2000mW did that mean it is a 2 watt? The G9000 is 6000mW what would the increase mean? Does that mean its 6 watt and does that mean better range in reception and transmission? The only difference I see is that number and the Os(s) supported is a bit higher for windows and Mac.

Also besides the Kasens models I have been looking at Alfa models that look similar on the outside but they have different chipsets. Is Realtek RTL8187L and ralink rt3070 chipset the same? I would guess not but is Realtek and Ralink the same company or related in some way?

I agree with your mW conversions. My routers are maxed out at 251mW, a
big difference
from yours. It's nice to know there's other models out there. I'm
unsure a higher power buys
you anything, perhaps if you were located miles away from the city.

Your conversions are correct. More power does generally translate into better range the caveat being obstructions notwithstanding. If you have a large building in between your transceiver and the city transceiver, additional power may not make much difference (I believe WiFi signals are generally considered 'line of sight').

You can think of a WiFi link as a set of two virtual bridges between your transceiver and the transceiver of the service provider (in this case, the city). One bridge handles traffic from your transceiver to the service provider transceiver (these are the requests from your computing equipment, smart phones & TVs, tablets, laptops, etc.). The second bridge handles traffic from the service provider transceiver to your transceiver (the web pages, emails, etc.). By increasing the transmit power of your transceiver, you are in essence making the first bridge longer or able to handle traffic from further away. But unless the power of the service providers transceiver is also increased, the second bridge remains the same. For improved connections at greater distances, both bridges need to be addressed. Since we can't easily modify the service provider side, that means improving the sensitivity of your transceiver. This is best accomplished by the addition of a good external antenna to boost reception to make the second bridge longer.

So if you are moving up to a more powerful transceiver, it would be a good idea to also look into improving your reception. In combination, you should be able to improve your QOS and connect to transceivers further away.

so your saying not more sensitivity in reception just transmission. What about an amplifier on the coaxial antenna cable? Do they make them and can they help or like a TV amp can also amp the garbage of a signal and not really help?

Also whats up with the two antenna USB WIFI dongles do they get better sending and reception quility? could I attach each side to a cable to an outdoor antenna on either side of my house to pull in Starbucks on one side and McDonald's on the other? Can the antennas be separated or both have to work together?
