RF Amplification ( Signal Boosting) (modified 0 times) pbrandonc00 Profile I was wondering if anyone knew if it would be possible to use the led's on a 802.11b card like D-Link DWL520 to do the tx/rx switching in an Rf amp?? 03-29-2003 18:59:41

RE:RF Amplification ( Signal Boosting) (modified 0 times) 02U2 Profile According to one individual @ seattlewireless.net, Beware with DWL-520 and ADM8211 (DWL-520c1), this chipset has a very bad receiver sensitivity. Althrought in manual sensitivity is -84dBm i cant even associate with -54dBm. If i use exact the same transmission line and antenna ( i only change DWL-520C1 to DWL-520 rev B and of course change driver) the radio associate like magic with excelent signal 46dB SNR!! I wrote to Admtek they send to be linux driver(binary) but not more any help if i can change sensitivity by soft. This card is to me for indoor use only and in the same room without walls (IMHO). http://www.seattlewireless.net/index.cgi/DlinkDwl520 07-19-2003 12:38:03

RE:RF Amplification ( Signal Boosting) (modified 0 times) 02U2 Profile WOWZERS! I'm writing this sitting about 1 block away from a public access point using a SMC 2532W-B 200mw pc card and a 2.4 ghz flat panel antenna! THIS REALLY ROCKS! No more waiting for front row parking!!! AWESOME! Of course it is unsecure but still rocks! Wonder if I can warm my pastry in the morning with this setup... 03-17-2004 19:39:16

RE:RF Amplification ( Signal Boosting) (modified 0 times) 02U2 Profile Evidently Asus sells a Usb wireless adapter that is similar to the Hawking H-WU36D. http://usa.asus.com/products/communication/wireless/wl-140/overview.htm 24MW power output. Lot safer than the 200mw pc card that I tested above and seems to get almost the same results. 03-21-2004 11:10:15

RE:RF Amplification ( Signal Boosting) (modified 0 times) 02U2 Profile I finally took the bottom cover off the Hawking H-WU36D while waiting for one of my feral Cats to show up for it's daily dinner. The PCB assembly has ASUS WL-140 stenciled on it. Evidently Hawking just rebadged these. 04-09-2004 09:43:14
