Mixing Wireless “g” With “n” Range Question
My laptop has built in wireless “g” and I am having problems hitting wireless “g” systems in hotels and such, when I am on a fringe area. I was wondering if anyone would know, for sure, if I used a wireless “n” usb network adaptor, like a Linksys WUSB300N card, on my laptop, would it increase the distance or range that I might be able to get a better connection. The question is, does the “n” unit have better receiving sensitivity when used with a “g” router, than a “g” card in the laptop, or will it just be the same as using the built in “g” card?
In effect the answer would most probably be no.
But to get a more accurate answer you would need to compare the sensitivity specifications of each device. The device you are connecting to is of no relavence in this question as it is the constant.
If you ignore the sensitivity, then yes and no... the N would have no effect, but the external USB that can be moved around for a good signal is a plus... (look at a USB wifi dongle and a USB extension... I have a 15 footer so when in a motel I can lay on the bed and hang the cabl/dongle off the coat hook on the door.. when not far away, I can just unplug it and use the built in one....
you will get better range with a high power 802.11bg device with good recieve sensitivity -96dBm like the
200mW EUB-362 EXT

I have tested the latest n products and they do not compare for range even using a n router. 802.11n requires that the transmit power be reduced because it uses many channels and causes noise for other access points.
The only thing 802.11n gives you is more throughput but for internet access even 802.11b speeds are overkill.
AS fas as I can tell the only good application for 802.11n that 802.11bg can not do is streamin HDTV.
there is a good writeup with spectrum plots here
